Air in pump basket

[Nclonglorn]

I have a Jandy Stealth VSP, where the pump basket is integral to the pump. After a filter washout/clean up back in May, I noticed that after starting the system back up, I had an air gap in basket, even when running at 2500 rpm.

I was worried, but let the system run. The flow didn’t seem as strong as it should have been. After looking at some sites, I went ahead and ordered a new lid. Before it arrived, I took the filters apart again (they were really dirty anyway) and when I put it all back together, no air in the basket, and I thought all was well and sent the lid back when it finally showed up.

This morning, I shut it down to clean out pump basket again, and sure enough, when I put the cover back on, I’ve got the air gap again.

I tried a couple of reseats and lubed the gasket, but still no joy.

Any ideas on what’s going on?

Welcome to the forum!
Cleaning the filters solved it last time, might want to check them again.
I suggest you read through Pool Care Basics - Trouble Free Pool and even look at a few of our videos TFP-TV - Trouble Free Pool

I have a Hayward 2 speed. I noticed that I started getting air in the pump basket. Inspected and lubed O-ring, reinstalled. No change. Eventually I ordered a new O-ring, lubed it and replaced the old one. For about one week the behavior was about the same. I would go out there and, with the pump off, remove the lid and put it back on. I noticed that over the course of about a week and a half, I was able to get several more degrees of turn on the lid While tightening. Eventually the air went away. I think what was happening is that the old O-ring lost its compressibility, and the new O-ring needed A week or so to deform enough to make a nice tight seal. I would try replacing the O-ring with a brand new one, give it a good lube, and snug it up daily for a week or so and see if the problem persists.
