Water pump issue

[dms721]

My water pump sputters anytime I turn the faucet on. It does pump but seems to pick up air and sputters both hot & cold. I did try just a 5 gallon bucket of water into pump and still does it.. Pump has been replaced once. Thanks for any answers..

Another thing to check is the short hose line (if you have one) to be used for sucking anti-freeze into the system. If the cap on that line is loose then air can be sucked in.

Ours does that if we don't change the setting from city to pump/tank use outside.

If the pump sputters there is an air leak. a small enough hole may not drip water but will leak air.. Inspect the water line between pump and tank.

ALso remove line from tank if you can there may be an outlet strainer and it may be clogged.

Sputtering Hot & Cold..........air is being pulled into SUCTION side of pump
Suction line from fresh water tank
Winterizing Kit
Strainer
Pump casing

those are the places air can enter....suction side of pump

There may be a small leak between the water tank and the pump where air is sucked in.

If the problem is just fast cycling of the pump, drain the water heater and refill to establish the air pocket in the top of the tank.
