What is the flow rate of the valve? My tankless needs at least .4 gpm to activate.

I do not think that this valve will give you the required flow while hot water is not being used. It is designed to work in series with the Watts circulating pump and as such I do not think that it will have any effect in a tank-less hot water system.

I talked to someone that said these valves only operate at .2gpm and that's what makes them no good for tankless

you can probably have as much flow rate as you want. i just have to get it to connect with them pump

we have an electric tank less that is rated at 4.5 GPM. We have very hard water in this part of MA and also have a well. We have been in this house for 30 years and have had problems with pipes rotting away. When we installed the electric tank less we installed this filter also. We used the heater for a few months and than had the plumber perform the maintenance suggested by the tank less mfg. It was clean as a whistle. Our flow rate is not as high as yours but if you had one in line with each heater - i would think it would work fine. Our heater used 120A for 4.5 GPM - if yours is electric it most use a lot of power! For our use I am very satisfied with the filter and given our water quality situation and how clean the heater was - i would highly recommend this filter. KR in MA

Hello,If you are using 1/2" pipe throughout the calulated flow rate for one SW-37 wnd the TopsFlo pump is 0.17 gpm. If you have very long runs it may be slightly slower. While this seems like a very low flow rate it is adequate to remove all the sloar heat from the panel efficiently. If you have more than one panel the flow rate will increase due to the fact that they are connected in parallel.Thank YouHeliatos Solar

It all depends on what you have in your tank and how much flow you would like or need I have two of these on either side of my tank and it's a 26g nano softie/lps reef tank. If you have a fish only or a freshwater tank and just looking to had some circulation in the tank than this should be fine although if this is the only pump your adding I would suggest the next higher model up I believe it's around 420 gph? Hope this answers your question

Not that I know of. I think it's pure physics since all of these style faucets with the pull out nozzles have smaller diameter hoses in them. You could do a simple test and check the actual water flow in GPM and compare that to the mfg rated flow. I'm happy with the flow rate and we are on a deep well with pressure much lower than city water.

It is not a 68 GPM pump. It comes close to 68 gal per hour, however. I also wanted to decrease the flowrate and I bought a (Pulsed Width Modulator)PWM. This did not work even thought my voltmeter showed a smooth increase and decrease in voltage. I tried the PWM with a different motor, a battery operated cooling fan we used on our dog kennel when we flew with them. The PWM controlled the speed of the fan nicely. I don't know exactly why but it did not work with the pump. I was using 2, 6 volt batteries in series to get the 12 v for the motor. When I used just one 6 v battery, the motor ran at slower speed and this would have worked but it was still more output than I wanted. I would up installing a tee on the discharge with a small valve at the outlet so that I could control the discharge while allowing a significant portion of the flow to bypass throught the branch of the tee.

need to define "very low output water flow". I fill a 5 gal container in about 1.5 hours. with 45 psi from the spigot

does this require high pressure? NO can it be used with a 12 v pump water system in an rv? YES how many gallons per hour? 30 GPM

I have a 27GL cube sized tank with this filter. The spraybar spreads out the flow. It is not to much current. With the water forced though the filter media, actual flow rate is half what Sunsun claims. Flow is not adjustable as is but I read online that you can buy a valve to put on the inlet hose to adjust flow.

An excell 2750 psi runs with 2.5 gal per min. The 3.0 size is a match. Charts are available on the web. You need psi and gpm

I don't know about the gpm; I had a plumber install. My water pressure and flow rate from the faucet is really strong.

That is just the model number not GPH. The flow rate for the 1200 is 315 gallons per hour and that is true flow rate not like marineland who boasts a 360 gph rate that is( by their own spec's) actually only 220. Hand down the penn plax is by far a better pump. I have 5 of them after going through fluval, marineland, API.

I just set my Finnex PX-360 up on a 10 gallon tank and I have the canister several feet below the tank. I'm not sure how much it effects the flow rate (it's definitely stronger when it's closer to the water level) but I still get very strong flow (in fact, maybe a little too much for bettas - the only way to change the flow is by raising and lowering the canister, I don't believe there's a pump speed controller.) I have an inline UV sterilizer and it doesn't seem to be detrimental to the flow rate.

From my experiments, I have calculated that this 50 GPD Flow Restrictor produces a flow rate of about 442ml/min. Reducing the flow of the water source produces the same results.

I have a 2 gal tank & it takes my viair compressor 4 minutes to fill up to 75psi

Dunno about the particals, but the flow rate is supposed to be 3.5 gallans per hour flow. I use two of these in a Rotax engine on an ultralight aircraft which burns about 3.5 gph and not had an issue in 12 months so far. Its good to be able to see the filter condition through the glass.
