This should be equal to or greater than the amount of water the pump can push up our of the well in one minute. The amount of water you can take from the tank before the pump starts to run is called draw-down. What you're looking for is about a 20 psi differential between the cut-in pressure and the cut-out pressure, with the maximum pressure not exceeding 70-80 psi. It may be set for 40-60 instead of 30-50 but that's OK. Probably set to turn the pump on (cut-in)when the pressure lowers to about 30 psi and turn it off again (cut-out)about 50 psi. What Goldhiller said - The switch on the tank tee is probably a pressure switch not a reset switch. Knowledge is power, but only if applied in a timely fashion.
If your kick-in is 30psi.you may have to let off some air (to 28psi) or the pump won't turn on. Pretty sure that WellXTrol comes with 38psi precharge (lots of tanks come pre-chage of 27psi). 30-50 switch is pretty standard, but who knows how yours is currently adjusted. Check that kick-in before you remove the old tank so you know what you're shooting for. to 2-3 lbs less than the kick-in pressure on your switch. Bigger tank equals less frequent starts of pump and that equals longer pump life.Īdjust tank precharge via Shcrader valve (looks like tire valve).without any water in the tank. 30 would be great, but you don't likely have room for one that large. At least absolute minimum drawdown of 6 gallons. Get the biggest tank you can afford and that will fit in the space you have. It screws into the ell on the bottom of the tank. Standard fitting for bladder tanks hookups, so your tank likely is a bladder type. The fitting you're referring to is known as a But it may not have provision to renew the bladder. If it's painted as opposed to galvy, then it likely is. If your time is worth 's a waste of it.Īnd I'm not familiar with that AO Smith tank. I've done four or five and I ain't doin' another. Replace tank instead.įrankly.replacing bladders is be a big pain in the butt and most folks just toss in a new tank. No big plate with perimeter bolts under there.so no bladder replacement. Some of these bladder tanks allow for bladder replacement and some don't. Can't tell if you are, but before you toy with the notion of replacing just the diaphragm, you'd best make sure you can.
