This is my first season with a pool and I'm trying to do as much myself as possible.
I've backwashed/rinsed the filter and while it's running in backwash mode I get about 10PSI. If I set it to filter, even with no DE in it, I get about 25 PSI. I loaded in the DE and it's still reading around 25PSI.
Is this normal operating pressure for one of these filters? I'm just looking for some general guidance about where they should run.
