    Pump strainer question

    I just finished my build.... I have a 1hp pentair... I see tiny air bubbles coming from the returns.... But the pump never loses prime... Should the strainer basket on the pump be full of water? I can see water sloshing around through the clear lid... Should there be air in there? Or should it be so full you can only see "still" water....

    Re: Pump strainer question

    In my experience once the pump primes and runs for 10 min, I have zero air (sometimes a small 2cm bubble) and it stays that way until I break vacuum on the plumbing (after the pump is off).

    You have an air leak if you constantly have a significant amt of air in the pump basket.

    A common place is the pump basket lid o-ring. Inspect and generously lube. After that run water over each PVC joint for about 5 minto see if air moves out of the basket.

    Goodness, you did a DIY build in a month? Sure would like to see some pics of that. That's insane bordering on incredible.

    Congrats!

    Haha... Thanks!! And I did everything by myself!! Except the dig...

    Depends on how much air! If the leak is relatively small you see what you have.
