I think I am finally figuring out this well pump system of mine. I have a pump with a squareD 9013FTW2 pressure switch on a ProSource PS19S bladder tank that supplies well water to a large aerator tank. The aerator tank supplies to a pump with a 9013FSG2 pressure switch on another ProSource tank like the first. This pump/tank supplies the house. Wanted to make sure all pressures were correct.
The house pump/tank is set to 50/30 as seen on already installed gauge. I decided to check the air charge to the the tanks for the first time since it was installed 2 years ago. Found the air charge on the empty house tank was only 12psi. Pulled out the compressor and pumped it up to 28psi. Turned the pump back on and pressured up the system. Came back up to 50. Turned off power and opened a valve. Couldn't tell the exact cut in pressure the contacts closed at because the crappy chinese gauge that somebody put on started sticking. When the house was built and the well system was installed, I found the gauge on the house pump was cracked and not working. I told my construction manger and somebody installed this Made in China gauge. I will replace it tomorrow so I can verify the cut in pressure. Is it correct to assume that the bladder in this tank was being overexerted with an mt tank air charge of 12 and a cut in of 30?
The well pump/tank that supplies the aerator has a pressure switch that only has a range nut, not a differential nut. Now, all info I have found says the switching point on the rising pressure (cut out) is adjustable, but not the falling pressure (cut in). However, inside the cover of the switch, it says to turn the nut to raise the on pressure. Is this turn-on pressure or pressure while pump is on? Below that it says the on pressure is 30 and the off pressure is not listed. The non adjustable differential of this switch is suppose to be 20. In reality, it isn't 20. I found this pump set to 30/20 (courtesy of a new SS fluid filled gauge). I am wanting to spread the gap, but with the differential being n/a, it has become a little difficult. I have found that as I tighten the range nut, the differential is increasing a little. Currently, I have it at 36/21. The empty tank has an air charge of 18. I am trying to maintain the cut in at 20-21 and raise the cutout. Why the contradiction between the label in the switch cover and documentation from the supplier? Or, does "on pressure" mean the same as "cut out"? And why isn't the n/a differential always 20.
One other question...my tanks are 19gal capacity and have a draw down of 5.8 (50/30) or 6.9 (40/20). If draw down is how much water comes out before the pump comes on and the air charge on the tank is 2psi lower than the cut in, am I correct to assume that the tank doesn't fill to capacity, but more like a little over the draw down?
Hope this isn't too much coming from a newbie. I appreciate all the info here and look forward to help understanding this stuff.
