Air charge too low in pre-charged tank.
DISCONNECT POWER and open faucets until all pressure is relieved. Using tire
pressure gauge, check air pressure in tank at valve stem located on the tank.
If necessary, pump air into tank from outside source until air pressure is
equal to cut-in setting of switch. Check air valve for leaks, using soapy
solution, and replace core if necessary.
Air spurts from faucets.
Pump is picking up prime.
When pump picks up prime, all air will be ejected.
Leak in suction side of pump.
Suction pipe is sucking air. Check joints.
Well is gaseous.
Change installation as described in manual.
Intermittent over-pumping of well.
Lower foot valve if possible, otherwise restrict pump discharge.
