The Zoeller Model 507 manual (Section: 6.10.070) provides the following table. Discharge Flow Feet of Head Gal. per Min. --------- ------------ 5 23 10 15 15 5 17.5 Shut-off Head The above data assumes a fully charged 12 V battery. Hope that this helps.

I restricted the flow on the 2 pumps I bought, it did not damage them. The pump did not work any less just a slower flow of water.

The closer to full the tank is, the fewer pumps it takes. For a full tank, it takes me about 20 pumps to fully pressurize the tank.

The first one I had would but the second one got hot and never worked again. I would still recommend this pump. It's a hard worker and one bad one won't keep me from buying another.

That I don't know. I've only owned the one fountain. I have had for over 10 years and replaced the pump only once.

You can only pump once. That one pump is enough to carry it at rated speed. If you do it more than once nothing more happens.

Hi I have a two tier fountain and the pump is almost enough . You need a more powerful pump .

The pump has an automatic water level switch, not sure about height of discharge

There are 2 pumps that are controlled by 2 knobs. However, it circulates automatically using 1 pump to keep the temperature set.

I'm not totally sure but I would think it would matter more if you are pumping it vertical vs horizontal. I can tell you that i tried pumping water from a small sump tank up to the main tank and it struggled. I ended up raising my sump tank about 3 inches and that made it work fine, it just couldn't fight the extra pressure of those few inches.

2.2 GPM with both on. with one on I would speculate it is more than 1.1 as it increases the water output of the single device. I would guess maybe between 1.4 and 1.7 with just 1 on.

It comes with multiple adapters. Don't expect it pump water up more than 2' or max, 3'.

The pump does not make much noise...it's quiet unless the water level is below the intake.P

Mine pumps seven feet but I had to move the check valve to three feet off the floor. I think the weight of the water on the valve at one foot was to much for the pump to push the valve open again. Plan on buying a check valve, the one that comes with it is junk. Overall it's a good pump.
