Home Improvement Asked by JM1 on February 22, 2021
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 feet long to the filter and another 12 feet 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.
It seems that the water flow on high speed is too much for that skimmer and air is sucked into the water flow. Apparently a higher capacity skimmer is required, or run motor at low speed. Or add a second inlet ,skimmer or bottom.

If you have separate valves for the skimmer and drain, reduce the skimmer flow and increase the drain flow. You're operating your skimmer at a higher suction rate than it can handle and therefore sucking some air. Is the pool full? You might have to increase the water level of the skimmer. If you just have a skimmer and it's always full, then check the lid over the basket on the pump to make sure it tight and that the "o"ring is good. Also check your pump inlet connection for tightness.
