Pump is cycling off and on
Pressure switch not set correctly
Cut off pressure must be higher than valve pressure. Reset pressure switch cut off to at least 10 psi higher than valve pressure.
Waterlogged pressure tank
Bad or torn diaphragm
This is usually due to back pressure being higher than 150 PSI. You will have to change models to a CSV1A if this is the case. Replace valve.
Demand is more than pump can provide at desired pressure
Reduce demand so it is within pump capabilities to maintain desired pressure.
Check psi marking on valve
Switch to correct model valve
Too much air in tank
Reduce air pressure in tank to 5-10 PSI below pressure switch cut in pressure.
Pump rapid cycles at start up and then begins to function correctly
Pressure switch is located on the main line or closer to the main line than the pressure tank.
Move pressure switch to small line at the base of the tank on a line no larger than 1 1/4" in diameter
CSV setting is too close to cut off pressure
Set pressure switch cut off pressure at least 10 PSI higher than CSV setting
Air pressure in tank too high
Reduce air pressure in tank to 5-10 psi below cut in pressure.
Multiple check valves in system working against each other
Remove all but the check valve or foot valve on the pump itself.
