here is the problem with my water pump control switch settings. the water is being used, runs dry and stays off for sometimes 3 minutes or so.i realize the springs control the cut in and cut out. do i need to make the spring more compressed to make the pump come on sooner? or do i need to make the spring looser to make the switch come on sooner?when i read/hear about adjusting the cut in. the answers seem vague because i do not know the perspecitve of the spring.does compressing the spring make the swith flip easier? or does compressing the spring make the switch harder to flip on?i installed a new 30/50 switch today. My air tank was at 50 or so PSI. but i dropped it to about 30. is the goeal to make the entire full system 50 pounds? because after my pump cycles i get about 70 psi!!!
The problem lies with the new 30/50 switch. With Your pressure tank empty of water, set the air pressure at 28psi. What is happening is when the water pressure drops below about 45 psi - the air pressure (50psi) on the bladder is forcing the water out rapidly. Then the pump has to work like cracy to overcome that bladder pressure! Easy Fix. Make sure the tank has no water in it.
with the switch set to operate at 30/50 the tank should have 27 or 28 pounds of air with no water in tank and a faucet open with pump turned off...once this is set the pump will come on at 30 and off at 50 if it goes higher than this the switch is bad or the adjustments have been changed....tightening the tall spring turns both cut in and cut off pressure higher...loosening the tall spring turns both cut in and cut off lower....the short spring sets the difference between the two...tightening the shorth spring raises cut off pressure only...loosening the short spring lowers cut off pressure only....
