Hey guys... This is an amazing forum.
I have a decent size inground vinyl pool.
I am getting a lot of air in one of the returns, and I notice plenty of air in the gasket. The pressue is normally perfect, and the pool does not seem to be losing water.
I never turn off the filter. I let it run 24 hours a day in the summer, only putting it on a timer if I go away. Because of this, I end up backwashing the filter and adding new DE about once a week. I don't have a good reason for this, other than I am in NY, and the pool season is so short, I figure, let the thing run and be clean
My problem is when I backwash the pool and add DE, the pressure drops very significantly. What I need to do is, wait for a few hours with the filter off before I turn it back on. If I give it about 2 or 3 hours without running, the pressure will come up to 19 which is exactly where my pool normally sits at, and the jets look great. (Other than air in one of them)...
If I just backwash, add DE, and turn on the pump, the pressure stays at about 7, and the jets barely feel like anything is coming out. This happens without fail, every time I backwash the filter.
I put in brand new pavers around the entire pool before these issues, and I really dont want to dig them up. This is why I am not messing with the plumbing for the air that is in there. Most of the time the pool runs great, just a little carbonated
Any help or suggestions you guys can give me would be greatly appreciated.
