Shipping

Please check the shipping address listed in your paypal transaction as you check out! If that address is wrong contact me ASAP since I pack and ship orders quickly and I do it based on the address paypal gives me. I prefer you have a confirmed paypal address since unconfirmed addresses mean I need to confirm the shipping address with you (this takes time and can delay shipping.) If you get an e-mail from me with a subject like Re: Payment received from your e-mail@your e-mail.com it is me trying to confirm something about your order before I can ship, please open it and respond if you want your order shipped asap.

I do not earn money on the shipping. The paypal calculator is not very flexible so if it over charges you for shipping, I will refund the difference. There is a place on paypal where you can add instructions about shipping (for instance if the shipping address is a business address according to UPS/Fed Ex it might allow me to save you money on shipping for certain products if I know about it, otherwise I have to assume residential shipping. If you add your phone number there I can use your phone number if I ship via Fed Ex for certain products and they can call you if there is an issue with delivery.)

If Paypal doesn't charge you for shipping, it is probably because you are in another country or someplace I don't normally ship to, I will be contacting you about it since I will need to find out the shipping costs to your location and send you an invoice for the shipping or refund your order if I can not ship to you or if you don't want to pay the shipping. I normally Sell in the USA but have occasionally shipped packages internationally.

Plants and Fish I only sell in Florida at this time and I am not set up to ship fish yet.

Return and Refund Policy

I try very hard to quickly answer questions about products before the sale. If you are uncertain about a product please ask, I want to make sure that what you buy is what you need and what will actually work for you.

If you buy a product and change your mind about it later and want to return it, I will have to charge a re-stocking fee and I can only accept returns on unused items. I can only make refunds for 60 days after the purchase through paypal. I do not refund the shipping or pay return shipping unless the reason for the return is on my end.

Please contact me for instructions before returning anything. If I'm not expecting something to come back, I won't know what to do with it if it actually makes it to me. Some packages are shipped direct from the manufacturer and simply mailing something back to them won't get you a refund.

If there is a problem with a product, please contact me so we can work something out. Some items are covered by warranty.

  • Hello, I’m installing 3- 4x4x1 foot (16 cu. ft. each) media beds on my aquaponics system. Looking to maybe expand it to 6 beds at some point down the road.Want to flood and drain it and need an indexing valve and some advice. I will be using a 9-1200 gal danner submersible pump and 1″ pvc. What valve do you recommend? Any advice and a price on the valve would be greatly appreciated. Thanks,James

  • TCLynx

    Above are the list prices but if you want to find the discount prices from your Aquaponics Indexing valve dealer in your area, Check out this link http://www.aquaponiclynx.com/indexing-valve-dealer-map.htm
    and click on the map for your area till you get to the contact information for your dealer or to their price list.
    Any of the six outlet valves can start out with a 3 zone cam and later be set up for 6 zones. Just make sure to cap the unused outlets in some non permanent fashion.

    However, I’ve never tested the pump you mention with the indexing valves. I think it will probably be strong enough to operate the 1 1/4″ 6 way valve with the Gravity Modified Stem Disk Assembly as long as your heights are kept minimal. In my install where I am using a less powerful pump to operate the gravity modified 1 1/4″ valve, the fish tank is in ground and the valve is installed less than 18 inches above the water line and the tops of the grow beds are only about 18 inches above that. I made sure to upsize the plumbing from the pump to the indexing valve and I minimized the length of the plumbing runs.

    The Danner MD18 (or 1800 gph) pump can handle any of the indexing valves with the low flow (normal aquaponics) stem disk assembly.

    You will need a timer to turn your pump on and off since the valve only indexes forward when the flow to it stops.

  • Brian

    Do you have anyone in Hawaii that sells these Valves?

  • Bill

    Hi TCLynx,
    I have enjoyed your website and prolific and informative posts on Aquaponic Gardening. I am in the process of building a deep water trough and raft AP system, but am having some second thoughts about media beds. My current plan is to continuously pump from the last trough into the fish tank which is maintained at constant height with a stand pipe. My question is can I use an indexing valve to alternately feed several banks of half barrel media beds using only the gravity flow from my tank? I will have about 3 feet of head (water level in fish tank to water level in grow troughs) to work with. I have never used an indexing valve but understand that I will have to interrupt the water flow for it to index. Does that mean I will need a solenoid valve to accomplish this task? Your thoughts on this will be much appreciated. I expect total system flow to be on the order of 20 gpm. Thanks for you consideration.

    Bill

    • TCLynx

      Hi Bill,
      It is possible to operate an indexing valve under gravity flow provided you have a little bit of head to work with. However it is challenging to figure out some means of stopping/starting the flow to the valve since most inexpensive solenoid valves won’t operate under such low pressure nor will they allow enough flow through at those low pressure to operate the indexing valve.

      I have operated (just for testing purposes) a 1 1/4″ gravity modified indexing valve using a Barrelponics sort of flush tank. The high water in the flush tank was about 26″ above the valve when the “flush” happened and it did work at least for the few hours I was testing it. Here is sort of a diagram

      Anyway, not sure if this is quite what you have in mind to add an extra tank to manage the flow to the indexing valve and the media beds since you would need to make sure the flush tank was big enough to hold enough water to flood one bed at a time.

      I am always working on other options and ideas for this. I have also made an automated high flow low pressure valve before but it quit working when a bug got fried in the electronics on me. Currently my big system is alternating between an extra pump in a Flush tank and when the pump turns off the FLOUT will sink to flood some other beds. See the Pumperflouternating blog post for more info on that.

  • Bill

    Thanks TCL, I don’t know that I have enough head space to add another tank. Perhaps I can modify the Barrelponics flush system to operate on just the top 1 foot of my fish tank (~1,000 gal & 7 ft dia). That would give me a flush every 10 minutes or so and with a four port indexing valve would flood and drain each media bed every 40 minutes. I don’t know how the fish would respond to the water level rising and falling every 10 minutes, and it would add more “stuff” into my fish tank. How much head does a gravity modified indexing valve require?
    I enjoyed reading about your adventures with the FLOUT system. Very ingenious adaptation.

    • TCLynx

      I like to draw the flow from the bottom of my fish tank (hence the SLO drain in my fish tank and the FLOUT tank next to the fish tank.)
      The indexing valve needs some where between 18-26 inches of head pressure with as full a flow as possible to really engage the gravity modified version.

  • Bill

    Yes, I agree. I plan to use a stand pipe with on oversized sleeve that opens only at the bottom of the tank so water will flow up from the bottom of the tank to reach the top of the stand pipe.

  • Blair

    Hey TCLynx,
    The above Indexing Valve animation seems to imply that the indexing valve only cycles due to a start/stop of the water inflow.
    IE It has no water coming in the animated piston pops up. Then water comes in and it cycles to port 1. Then when the water stops it pops the piston back up.

    Does it require the water to cycle ON/OFF/ON/OFF….

    And will a 500/1000 GPH pump be sufficient to work the low flow valve?

    • TCLynx

      Exactly Blair, the valve does require the flow to stop and start in order to index forward.

      And in general, NO a 500/1000 gph pump is not enough to operate the standard or low flow valves.

      There is a gravity modified version of the valve that I have manged to run in a limited set up (not pumping very high) where I did manage to get it to work with a Quiet One 4000 pump which is nominally close to a 1000 gph pump but it has more lift than most other 1000 gph pumps I know of. I generally recommend a Danner MD 18 or similar pump to operate most of the indexing valves and I usually only recommend the gravity modified version of the 1 1/4″ valve when I discuss the set up with the person and determine that the lift will be small enough and that the Quiet One 4000 will be able to manage the job.

      I usually use a repeat cycle timer to control the pump for these systems since it would require a more complex set up and a very big pump to use a solenoid valve to control flow to the Indexing valve.

  • Do you have any distributor in Hong Kong or Asia region?

  • antonio

    How does work a gravity modified a stem disk assembly? would that allow to use the valve upside down or in a orizontal position?

    • TCLynx

      No, the valve still needs to be installed the normal way around. The only thing the gravity modification helps with is to allow the valve to work at a slightly lower pressure and flow rate than the low flow or standard stem disks assemblies.

  • Marshall

    Would your gravity modified indexing valve work with our diaphragm pump?

    • TCLynx

      I don’t know anything about your diaphragm pump. The Indexing valves work with water flow, so is your diaphragm pump a water pump? I would need to know the flow rate and pressure the pump produces in order to tell you if it would work with the gravity modified indexing valve. I can tell you that the smallest water pump I have used the gravity modified indexing valve with was about a 1000 gph pump.

  • Adam

    We are trying to flow 18 gallons a minute. How much pressure will it take to index an 8 way indexing valve?

    • TCLynx

      I generally recommend the 1 1/4″ valves for the lower pressure applications to get the most flow with the least loss and trickling out the unused ports. The 8 way valves only comes in 1″. I do believe the gravity modified version of the valve will work on 18 gallons per minute at the valve (provided the pump is also able to pump at least 10 feet or so higher than the height the valve is at.) However, I have never personally used the 8 way valve to test it under low pressure applications.

  • Rudy

    Hey thanks for all the info TC. I need to pump water to 4 different grow beds each about 10ft off the ground. What disk assembly should I go with for that kind of pressure on the 1″ 4 cam? I have a mag drive 18 right now but I’m guessing I will want to be somewhere in the 2500gph range? The system will be about 6000 gallons

    • TCLynx

      Wow, 10′ off the ground? Is this system for Tarzan?
      But how high from the water level the pump is in will the top of the beds be? That is the important question. Head is measured from the surface of the water the pump is pumping from, if that fluctuates use the low water level to measure.

      I think perhaps with the 1″ 4 zone valve, if you were going with the stronger pump, you might want the standard stem disk. However hearing that the system is 6000 gallons (is that the fish tank volume?) I’m thinking perhaps you need the 1 1/2″ valve to get more flow through the system. The 1″ valve is going to restrict flow and unless you have a second pump and bio-filter going I don’t know that 2500 gph pump at 10′ head is going to take care of you on a 6000 gallon fish tank if you stock at all heavily.

  • Rudy

    Slight typo, the total head will be just under 10′. The top grow bed is a little over 5′ high, and the sump will be buried. There will be 2 tanks built like raceways (which as of now I’m leaning towards making them 3366 gal each). Ontop of those and to the side I’m planning on having 6796 gal of grow bed volume. I’m not trying to move a ton of water thru the beds, ideally I would want to circulate those maybe 4 times per day but if this will be a 1 pump system it will have to be much more for the fish tank circulation. Unless I use air lifts in the fish tank (forgot the actual name). The index valve will only be going to the beds, I’ll either have a bypass to the tanks or a 2nd pump (ever seen videos of an air atomizer?). Also the top level on each of the grow bed rows will be 6″ of gravel for filtration.

    I’m designing this for a navy SEAL who wants to go all out and get creative. His greenhouse is 23×84 and money is not much of an issue. Could it get any better? Haha

    • TCLynx

      I’ll recommend doing lots of reading before you finalize the designs.

      I like deep (12-24 inches of media) gravel beds for filtration and I usually flood them once an hour. Of course I also run zipgrow towers and Ive taken to running water through those on something like a 5 or 10 minute on/off cycle.

      I’ve been switching over to these diversion valves instead of turning my pumps on/off
      Automated Diversion Valves
      automated diversion valves this way I can alternate between pumping to the grow beds and then to towers or maybe I alternate pumping between two different indexing valves or maybe just alternate between pumping to the fish tank and pumping to the indexing valve.

      So how big is the fish tank going to be? You want to move at least the volume of your fish tank at the height required or even up to 2-4 times the fish tank volume depending on the type of fish and density of the stocking. What are the goals of this system? Is He more interested in growing fish? Or growing plants?

  • Rudy

    That diversion valve looks like what I will need. He wants mainly plants rather than fish. We decided against the raceway style fish tank. We’re going to go with (4) 1000gal tanks. Is there anyway I could get your email to send you a layout of what I’m trying to do to get your advice on it? I’ve been following your stuff for at least a year and would love your input.(I’m stoked to see your progress!)

    In a nut shell though there will be (4) 4×28 grow beds (plus a 4×56 raft) and in order to run a bell siphon on something that big I need the indexing valve. However I’d prefer my pump to stay on and the diversion valve to switch between the tanks and the indexing valve. I’d like to flood the beds 4 times per day.

    I’m also trying to figure out how Murray gets his “Flomedia” system to work, but if I can’t before this gardens set up I’ll just use 2 pumps for now until he releases his secret.

    Thanks TC

  • Marvin Sorg

    I am using a 1″ eight way standard flow indexing valve in my system. The valve does not index every time. I have approximately 25 GPM flow through the valve. I am using a diversion valve to interrupt the flow. Any suggestions why the valve is not indexing consistanly?

    • TCLynx

      I’ve never actually done any testing using the standard flow stem disk assembly. All my work with the valves has really focused on the low flow stem disks (normal for aquaponics) or the gravity modified stem disks. That said, if your pump is only just barely providing 25 gpm at the valve, then any little thing might occasionally keep the pump from moving that much water which would keep it from fully engaging and therefore it wouldn’t index. However, if the valve is getting stuck on one outlet and not popping up properly, then the probably could be due to debris in the valve or the disk sticking inside the valve due to lime scale build up or possibly there are rough spots on the cam or stem that causes the valve to stick at a particular outlet.

      How long has the valve been installed? In the lower pressure applications I usually find that the bio-slime actually helps keep things lubricated so the valves seem to get stuck less after the coating of bio-slime builds up so I don’t actually like to clean the valves too well other than simply removing debris and maybe scraping the edge of the disk of lime scale is building up but I otherwise try to leave the slime mostly intact.

  • Marvin Sorg

    I have only 2 of 8 growbeds on line at this time and the unused ports had short lines into a sump. Air was getting back into the valve body and SEEMED to be causing indexing problems.I installed loops down into the water in the sump to avoid air getting back into the valve.
    I am still checking out the operation but it seems to be more consistant.
    thanks

  • DAVE

    I hope you can help me, I seems that I have quite a strange problem with this FIMCO Valve.

    > I replaced a 34 year old existing FIMCO 4-Outlet, 3 cam valve system for an exact replacement 4-Outlet Hydro Indexing Valve for home sprinkler irrigation, using a 3-zone cam – for my 3 zones of yard grass.

    > Everything was going good for about 2 years until one day I needed to prime the pump (Check valve must be messed up and not preventing water from going back down into the well) – but that’s not the problem. I’ll fix that later.

    > I have a:

     West Zone
     North Zone and
     South Zone

    >> Problem: The West Zone will go on and then the North Zone as normal, but then go back to the West Zone.

    > Then I’ll go to the timer and turn off the (2nd ON time) West Zone, then turn it back on and it will go to the North Zone again. Then I’ll turn that off again and then back on and it will go to the SOUTH ZONE – by hand but not automatically. WEIRD……

    > Back to above, to when I needed to prime the pump.

    I noticed that every time I primed it – that it would go forward one Zone. Well I know that makes sense because I am pushing water now through the cam and making it go to the next Outlet.

    > I realize that when I do prime it – that it is most likely filling up with water before the check valve and then filling up the pump itself and then going to an Open Outlet and activating the Plunger type thing going up and down around the cam.

    I’m sure that if I screwed it up this way that I can Fix it this way too?!?!?!?

    What do you suggest?

    Thanx for your help, Dave in Plantation, FL

    • TCLynx

      Dave, I am not in the business of selling these valves for non aquaponic purposes and don’t have the time to spend fixing situations not related to my own sales.

      I have forwarded your message to FIMCO you may follow up with them if you need more help. Only thing I’ve ever experienced that makes the valves skip a particular outlet consistently is not having the correct cam installed.

  • Ben

    Hi, I am really interested in buying one of these valves for my compact aquaponics system. The plan is to start a system in a small 7′x8′ greenhouse. The three walls without a door in them will have grow beds that come out two feet from the wall all the way around. This leaves just enough space in the middle for me to put the 250 gallon fish tank underground. I plan to build this system without a sump, so I’m thinking five different grow beds. The pump will have to be pumping about 7 feet high, if I plan on four feet below ground and three more above for the water to get over the top of the grow beds. How would an indexing valve work for this kind of a setup? Thank you so much!

    • TCLynx

      Yes it could work, you just need to have a strong enough pump to operate the valve and some means to stop/start the flow to the valve. This can be done with a Danner MD18 pump and a timer but turning that size pump on/off all the time tends to break the impellers in about 4-6 months. Now days I like to use one of those motorized pool diversion valves to divert the flow back and forth to the valves so I can leave the pump running all the time.

      It may be possible to use a somewhat smaller pump and the gravity modified valve but I have only tested a few pumps at lesser heights for this and if a pump looses efficiency (for instance if the impeller loses a fin) and isn’t pumping enough water flow or pressure anymore the valve will stop working properly so at the heights you describe you will likely need a bigger pump and larger pipe sizes to make sure the pump can do the job.

  • Ben

    Thank you for the quick reply! How exactly does this pool diversion valve work? Also, how is a cam different than a water outlet? The indexing valve needs to be placed above water, right? Would I still have enough head pressure at four feet? What size pipes should I be using? Sorry, lots of questions!

    • TCLynx

      the Pool diversion valves are automatable motorized valves that can be hooked up to a timer or controller that will tell the valve send water to one outlet for a certain amount of time and then send water to the other outlet for a certain amount of time. I have one system where the diversion valve sends water to one indexing valve for 10 minutes and then to another indexing valve for ten minutes. I have 12 grow beds on that system.

      Yes the indexing valve needs to be placed above the water level. There are different cams that can be installed in the valves to allow you to feed different numbers of outlets. The outlets are the actually plumbing parts.
      If you have a strong enough pump, you can have enough pressure at 4 feet. If you get a pump that will only provide enough pressure at 18″ and then install the valve at 4 feet, it may not work.
      You pipes should be at least as big as the indexing valve inlets but I often up size to 1 1/2″ plumbing between the pump and the indexing valve just to make sure I have as much flow/pressure as possible.

  • Ben

    Thanks, that helps. If the diversion valve sends water to different places just like the indexing valve does, then what is the purpose of the indexing valve? In other words, if I only had three grow beds could I just use the diversion valve without the indexing valve?

  • Ben

    So the parts I am going to need, besides the pump, are a diversion valve, an actuator, an indexing valve, and a timer. Am I missing anything?

    • TCLynx

      Well the plumbing to connect it all together and the system to use it with and the power for the pump and controller.

      As for the timer, it is a bit more complex than just a simple timer. To control the diversion valve you need to switch 24 V AC. I’ve made myself some DIY little picaxe controllers so if you are into electronics and stuff I can sell the diagrams for that. It will cost quite a bit more for me to actually make them for you or I might be able to hook you up with other options for controllers (we have modified some of the Bigelow Brook Farms controllers to control the diversion valves before) or a transformer and relay could be hooked up that will plug into any old timer as well as separate power to control the actuator.

  • Ben

    I’m guessing that the transformer and relay option would probably be the cheapest?

    • TCLynx

      If you can get a timer that does the times you want and know how to wire up the relay and power supplies and can protect it all from the weather, yea that is less $$.
      If you are handy with electronics and into something like picaxe or adurino or something you could build your own timer controller for a reasonable price and be able to program it how you want (single most expensive part of the controllers I’ve built has been the weather proof plastic housing and my time getting the parts and building/testing it.)

  • Ben

    I recently discovered Novaris’s sequencing unit using car door actuators. I also understand that this is something you have tinkered with. Is this a viable option? Do you know if he is still using this type of setup?

    • TCLynx

      I did try it a bit however I was never nearly as successful with them as Novaris was. I’m now using the motorized swimming pool diversion valves to send water to my indexing valves.

      If you are really good at tinkering and like that sort of thing, go for it. However, I won’t be of much help to you since I never got them to be reliable long term, the rubber bands kept breaking.

  • Troy

    Hello,

    I have a 8 bed aquaponic system and a 1500 gallon in the ground concrete tank.
    using food and drain with a bell siphon (timer).

    Thinking of expanding but need to split my flow or add another pump in order to do that.

    The highest point of my system (swirl filter)is about 7 feet above the water in the tank.

    pump is a 2150 gph with 20′ max.

    does the index valve need to go at the highest point in the system as the area that the plumbing comes together is only about 2′ above the tank water and then branches off from there. so this would be the easiest area to put a valve in and split the flow.

    the delivery line is 1 1/4 util just before the grow-beds which go to 3/4″ (each are valved to regulate the flow)

    I think the 4 ports would allow me enough grow room for the future. Do you think this will work with my system and if so what size should I order.

    Thanks

    Troy

    • TCLynx

      For an indexing valve to work, you have to stop and start the flow to it AND you also need enough flow and pressure to properly engage the vales.

      The Low flow stem disk assembly needs at least 6 gpm at 10 psi. The Gravity modified versions can operate at less pressure (as little as about 3 feet of water column) but they still need plenty of water flow, AND the flow to the valve still has to stop and start for it to function.

      The indexing valve doesn’t have to be the highest point in the system if there is enough pump pressure to activate it and it can drain somehow when the pump is off but if there is no way for the valve to drain back to the pump, then I would probably recommend the valve be higher than the grow beds it is feeding.

      It is hard for me to know if the indexing valve will work for you since I’m not really envisioning where you are planning to place it in the scheme of things or how you are planning to drive the valve.

      If you are planning to have gravity flow feed the indexing valve after the swirl filter or something, then you will need an automated diversion valve and I will recommend the 1 1/2″ gravity modified valve. If you will pump to the indexing valve, then I need to see a flow chart for the pump and know how high the valve will be installed at to know which valve is most appropriate for sure but pumping to the valve with that size pump I expect most any valve would work unless you are not sending most of the flow to the indexing valve. The low flow valves need at least 6 gpm at 10 psi and the standard valves need at least 10 gpm at 10 psi.

      You mention using siphons and a timer? I do not recommend using indexing valves with siphons!

  • troy

    thanks for the reply…. in my system everything will go to the index valve and then to a series of beds. the location where I would like to put the valve is at about water level of the tank so i can raise the plumbing so the valve sits above the water line or above the grow beds or both. The pump is only rated for 20 feet or 8.66 psi? so sounds like the gravity version is for me.

    the pump is turned on and off with a relay on a timer so no problem there.

    What size do you think and is the gravity version right for me…. other question is how much head loss should I expect with the valve or would it be similar to the losses in a 90 bend?

    Thanks

    Troy

    • TCLynx

      Hi Troy,
      I’ve e-mailed you the headloss chart pdf

      For lower pressure operation, I’ve found the 1 1/4″ gravity modified valve seems to provide the best flow with the least restriction while still operating with the minimal pressure and flow. Without being able to measure how high you are pumping or knowing exactly how strong your pump is I’m reluctant to guarantee the valve will engage properly. I have used the 1 1/4″ gravity modified valves with pumping up only about 3′ using a pump that was nominally a 1000 gph pump with a max head of about 14 feet but for most other pumps I would probably recommend at least a 1200 gph pump for a minimal head situation and much higher I generally recommend a 1500-1800 gph pump.

  • Marcello

    I am working with someone to design in AutoCAD the whole layout of their system first before we order parts. I am looking for a dimensional drawing of this index valve with the 4 ports so I can draw it up and run the plumbing to it? Also I was told the best way to install this is with the main inlet pipe facing down and the outlet pipes facing out, is this correct? or is there a better way to install this?

    Thank you

    • TCLynx

      I do not have autoCAD templates for the valves and I can’t seem to find a cad drawing of them.

      The Valves need to be installed with the outlets facing down. The valves use gravity in their operation so if you install them any other way, they may not operate properly.
