Air Locks

Twisting my lemon. Auto calibration on, de detected after 7 seconds when it's working properly. De not detected when an air lock is in the hose, pump keeps pumping and hardly any water coming through even at 99. If I stop the flow with the tap and turn it on again, it will blast out then slow down to a trickle. I just wish I could get a consistent flow.

Any ideas?

Disconnect closest to pump if you don't get anything out suck up the pipe to help it as sometimes can't push air through system and hose. All this while running on max.

Or check your filter in tank before pump.

As above, also check your connections as your drawing in air from somewhere......

Either that or you can sometimes get airlocks if you run low on water
