Ah yeah that was me too hehe. It's been an issue for a while.

So I don't see a vortex on the skimmer, and the leak detection company didn't find a leak with the skimmer, but speaking with others in the area they mentioned that we have a "black bottom" skimmer which is a type prone to leaks.

Yeah still have air passing through when solar is disabled, and the bubbles get larger at higher RPM's. I also tried shaving cream and pool lubricant on all of the PVC joints on the suction side but didn't seen any leaks. I guess another question I have, is if I just keep running it as is...

I only have the issue when running the solar, or the booster pump. At low RPM's the air bubble is small. At high RPM's, the bubble is around 6 inches deep. When the solar heater and the booster pump are running, the pump is nearly dry. I see air coming out of the returns all times that the pump...

I mean, yeah, it's working. But when the booster pump is on for the sweep, or I am increasing RPM to 2500+ to pump up to the solar water heater, the air bubble is a good 6 inches and the pump runs a bit dry. The pump has lasted just fine for 3 years or so, but my worry I guess is having to...

Appreciate the reply. Cavitation might be the wrong word. We had a leak detection company come out and pressure test, and they did not find any suction side leaks. I've replaced the pump lid, o-ring, etc with no luck. We have a variable speed pump, and at lower RPM's there is no to little air...

Hi there. We have an old pool, 25k gallons, with old 1 1/2” pipes. However, the previous owners installed a pentair VSP with 2” pipes, and solar water heater. The pipe reduction from 1 1/2” to 2” is causing cavitation and the pump to lose prime at high speeds. We’ve gotten some quotes on...

Booster pump is attached on the pressure side, after the water returns from the solar heaters. If solar is turned off I adjust the diverted to send water straight to the booster. Filter was cleaned about a month ago. At high RPM the gauge reads about 12 psi, at low RPM about 7 psi

It is being controlled by an automation system, Sun Touch system is the name

Here’s some more pictures

Thanks Jim. I’ve had it running all summer without the solar, and it does okay at low RPMs but once I turn on the booster for the sweep it starts pulling a good amount of air. I just turned the solar back on yesterday to test it, and it’s about the same as when the sweep booster pump is on...
