Hi,My problem is of this automatic water pump ,it is disrupt always I don't no why..I also want to knew what is the function of the pressure air tank??? The picture is here:
WHAT does it is disrupt always really MEAN?? OK, that said... pumps such as this work to maintain a pressure with two set points even though the regulator only has one indicated.. The lower set point which as pressure drops, the pump turns on, and the upper set point where when the pressure rises to that point, the pump shuts off. When the pressure drops to the lower set point, it triggers the pump to run. When the pressure rises to the upper set point, the pump turns off. If the set point is 50 pounds, it may turn on at 47 and off at 53, or the window could be smaller and on at 49 and off at 51. The air bladder works as a shock absorber, just as the shocks work in your car to smooth the ride. When the pump turns ON there is a pressure pulse that without the air space, would promptly turn the pump off again. This is called short cycling and will cause your pump to on-off-on-off-on-off rapidly. The solution is to refill the air bladder. People with well pumps instead of city water have this problem frequently as the air bladder loses the bubble and does not work as a spring or shock absorber. I have city water NOW, but I used to use a well (which is still operational if I choose to use it) and I experienced pump short cycling the very first year I bought the house. The thing IS, I was ignorant. I missed the thing about a well and a septic tank that also uses a pump to an above ground drain field. YES. I was STUPID because I had NOT paid attention. NOW, years later, I have learned, the HARD way mind you, how these sanitary systems WORK in real life in RURAL America....
