Can one drop cause that much air?

Okay, I’ve got a ton of air coming from my return jets. Tiny bubbles.

My pump housing doesn’t fill completely, but I’m getting plenty of pressure as measured at the filter. The pressure is what I would call normal when it last ran without bubbles.

Ive got a one drop every 7 seconds leak between the pump and filter.
I am not losing water from the pool, either during pressure or at rest.

can that much air really come from such a tiny leak? Of course I will fix it, but I want to get an idea as to whether there is something more to worry about.

Air in the returns is probably from the suction side of the pump.

If you have a SWG, it produces tiny hydrogen bubbles as it produces chlorine.

DSF,

Is this a saltwater pool with a SWCG?

A small leak between the Pump and the Filter should not cause bubbles out of the returns. It can however, let the water in the pump drain out when the pump is off. This would cause a lot of bubbles when first turning the pump back on.

Do you have a VS pump? Does the basket stay full overnight with the pump off?

When running, are there large bubbles under the pump lid?

When was the last time you opened and cleaned your DE filter?

What is the filter pressure?

Thanks,

Jim R.

Well, just to roll the dice, I cut the pipe cleaned the pipe dope and reinstalled on the suction side between my jandy valves and the pump.

Problem solved

I just did the same thing @DallasSocFan. Tried everyting to eliminate a suction side air leak. Checked, cleaned and lubed every union / o-ring. Smoke and soap bubble checked every connection. Swapped the teflon tape for teflon dope on the pump male fittings.... problem solved.
