Problems with air bubbles returning into pool
I have air bubbles coming back through the return jets. I did not have the problem until about a month or so ago. I have checked the fittings and the drain pipe at the pump. I even switched the filter basket gasket. (I have the same style pump running my solar heat system.....no air bubbles in that separate system after the switch.)
I do have a lot of joints since my old oil fired pool heater broke down last summer. It is not running through the old heater, but there are some new connections. But it was all done last year and I never had the problem until a month ago.
I have not noticed an leaks from any joints.
Any thoughts on this?
Thanks.
