Re: Monarch pump, lack of suction

Thanks! I've got plenty of water source, and the foot valve rubber is fairly new, but I'll double check that. At least the pump is good!|
: You did not mention the foot valve or the
: water source. If you are losing your prime
: you will want to make sure your foot valve
: is not leaking. Fill the suction line with
: water and allow it to sit for an hour or so.
: Go back and see if the water level is down.
: If so, replace the foot valve.
: As to your water source... is it deep
: enough? Your foot valve needs to be at least
: a few inches below the water surface or it
: will suck in air. Also, if shallow, it could
: be sucking up debris from the bottom,
: clogging the foot valve screen.
: Whatever it turns out to be, it sounds like
: the pump itself is okay. Air is your pumps
: worst enemy, especially on the suction side,
: and that is exactly what it sounds like. Air
: can also be a problem on the discharge side.
: Make sure your water has a clean exit with
: no air pockets.
: Hope this helps!
