I am working on a 24' round 52" pool with a 1.5hp, 2 speed motor and a 26" sand filter, with 1.5 inch flex pipes, one 12 foot long to the filter ans another 12 fool o e to the return.
When I run on low, no bubbles in the basket attached to the pump or the return.
When I run on high, it seems like it sucks in bubbles through the basket attached to the pump, I can see them and a bunch of super small ones come out of the return.
I've put in a new o-ring with lube and tightened it as much as I can and on high the bubbles still come in.
Is there anything else I can try?
Pump is a waterway SD 15-2n11m. To answer a comment, it is a permanent install
Thanks for the help.
