Returns making bubbling sound

[anisudha21]

Hello,

I have a built in floor cleaning system (paramount) and last two days returns started making bubbling noise. When the cleaning heads starts, bubbles coming in from that too. I can't find any leaks or anything. Is it something i should worry about? Anyone seen this before?

Sounds like you are getting air from somewhere, and you shouldn't be seeing that.

Pump running, air will only get into the system from the suction side of the system.

There is an article in Pool School on Suction Side Air Leaks.

First check all the easy things, be sure that the pool level is not too low. Then look at skimmers, either very full of debris, or perhaps a door blocked partway, either of which will cause skimmer to suck air. (I had a pine cone keep one skimmer door nearly shut and that skimmer was sucking air.)
Then look at all the harder to fix things.
