Will this system work with low well water pressure and/or rainwater collection water pressure, both of which are about 1 gpm?

System needs between 20-30 psi to be effective. Most "normal" houses have a water pressure of 40psi or better, which is why this system comes with a regulator. A low pressure well should operate at or slightly above 30 psi, so it should work perfectly fine.

I expect it would work at lower pressure. I would not guess at a lower limit but cannot imagin any damage to the unit as a result.

I'm not sure of any pressure numbers, but this works perfectly with normal municiple water services.

I measured 1.64 gpm, plus or minus about 0.03. That's 9% above spec. I've had the showerhead for several months, so any adjustment within the showerhead should have happened long ago.

We have a well, and our water pressure is lower than city water pressures. We have found the pressure to be more than adequate. I am not using the full amount of pressure because it is plenty strong.

This unit only requires a .4 GPM flow rate to ignite. Your water pressure has little to do with it, so it will likely work just fine. That said, if your water pressure is "all over the place", you may need a new pressure tank. It has a pressurized bladder in it that helps stabilize the water pressure as the pump turns on and off. I have a well, and the water heater works great, by the way. Good luck.

Yes, i have my own massage shower head with a rating of 2.5 GPM, and it works great. Make sure that you use the sealing tape while fixing the head so that there is no leaking.

If there is no water in the incoming pipe the unit still turns off and on per the timer. I doubt there is any pressure sensitivity, and expect it will work on a rain barrel as the time simply turns a valve off and on.

There are charts to look at. My read says a size 2 at 1.3 gal per min will give 1500 psi. Look for yourself. The 3 will work but give a lower pressure.

I think it would work for a much longer outage than that. I'm not sure what your pump is rated in gpm vs. basepump gpm, but as long as they're close, you should be fine.

I don't know the GPM; there are three of us in the house and if one let the shower going for the duration the next person may not have enough hot water so we have to conserve i have a 40 gallon hot water tank, i tried to change to a less water flow shower head but the ladies in the house objected they like it allot, i bought the extension arm along with the shower head and I would say i am glad I did.

I would say no unless you are running a couple hundred 1 GPH drippers. You need to be moving some water for this part to work. It worked well for me with a rain bird garden sprinkler, a oscillating sprinkler and the Latest set up of 20 ten GPH micro sprinklers. If you want something that works with drip tape or low flow application go with the EZ FLO. that will work down to 10 GPH regulator inline.

You can see a chart on depth/psi and some additional specs here: http://www.redlionproducts.com/clean-water/4-submersible-well-pumps/Mine is at 100' - I didn't get a chance to measure the gpm on my install, but it seems at least 12 gpm. Of course, my well is a slow artesian so I usually have 100' of head water on top of the pump. But so far it's been a great pump.

The valve is battery operated, so I see no reason why it should not work with your lower pressure. You may have to set it for a longer water duration time to get the amount of water you want.

I've used it with some very low pressure before. It will work with any pressure really.

It reads to .1 gallons so I assume it can measure that low of flow...but I have only run it from 3-8 gpm. Still works after two years.

Yes - that's what I used mine for. I put it on a timer so it only runs during waking hours. My water pressure is slightly below 70 psi and there are no problems.
