I recently had my single speed pump and old sand filter replaced with a VS Pentair pump and a Hayward sand filter. There would usually be bubbles in the old pump basket, but I figured it was due to the age (>15 years old). With the new pump and filter installed, I was able to start using low rpm pump speeds, which didn't fill up the pump basket completely, and had the filter pressure at <5psi. I figured this was normal since it could pump a certain amount of water in.
I checked it the next day, while it had been operating at about 2400 rpm for a while (still slamming after opening), and the filter pressure was at 22 psi, and there wasn't much coming out of the jets. I figured it needed to be backwashed, so I proceeded to do that. Upon getting the pump back to 2400 rpm after backwashing and priming, the filter psi hadn't dropped at all. It's normally at ~16psi after a backwash, so I was a tad confused. Then I noticed that there were still bubbles in the pump basket at medium speed, and even high speed, and now there were bubbles coming out of the returns even at max rpm.
I honestly can't remember if bubbles have always come out of the return or not, even with the single speed, but it seems after some googling that I might potentially have some air leaks somewhere? I'm attaching a link to video of the pool return, and then the pump/filter.
Any advice would be appreciated. Since then, I've rescheduled the pump to run at max rpm 24hrs a day until my slam process is complete.
