3152 ato pump issues loosing suction

[AdamNC]

It seems constantly my 3152 ato pump seems to be loosing its suction when in the reservoir. I have to shake the pump and/or flip it upside down to release air bubbles trap in it. The pump is in a 5 gallon bucket full of ro/di water constantly and has never been out of the water while running. The out take of the tubing is about 1/2" from the water surface. The unit itself works as I can hear the pump working and as I said once I shake the pump it starts pumping out water into the tank.

Hi Adam,

I think I am already answering you on another thread so I will continue the discussion there.
