A:  This works off the pressure and should be mounted on the pipe between the well and the tank. I would never recommend you screw anything to your water tank - not a good idea.

A:  No. The pressure switch, which is activated by water pressure, needs to be installed so it senses the water pressure that is in the flow of water. The pressure/bladder tank is air pressure and will not activate the switch.

A:  40-60 is a safe pressure for a 2 story house. You'll probably want to adjust it on the high side, unless you have low flow faucets and /or shower heads.

A:  I had the same cconfusion. We are in a five bedroom house and the plumber suggested going with the one that offered higher pressure (40-60). It works very well.

A:  What is your pressure now? They are adjustable so you can turn it up or down. I have the higher one and turned it up a few turns. Once you have your pressure what you want, adjust the pressure in the tank, look it up but if I remember correctly it should be about 2 lbs below what your pressure is. This will make it so the water flows evenly without the pressure noticeably going up and down while in use.

A:  I live in a single story house and I switched to to 40 lb. And I got a better water pressure result in the shower. I am on well water and I think it cycles the well pump to run more often, so if you're on city water, I'd go with the 40 lb. Everyone wants a bit more pressure at the tap, right?

A:  Hello Wayne, This pressure switch comes with a factory cut-on setting at 40 PSI and cut-off at 60 PSI. Warm regards. Schneider Electric Customer Care

A:  Yes

A:  Yes it does. Working really well.

A:  Not sure what you're asking. Pump turns on when pressure falls below 20 or 30 psi, and then shuts off well pump when pressure gets to 60 psi. I'm sure the pump will continue running until the pressure gets to what I'd call the cutoff, which is 60 psi. Hope this helps. Jack

A:  If you mean below where the pump starts the anser is no, it will keep pumping!
