Soooooo, the sand filter pressure has run around 18 for the last 6 years. I leave the pool open here, year round in Virginia so I can enjoy the beautiful water and not look at the cover!
This year, the pressure was running around 22ish- not a huge cause for concern. However, I replaced the capacitor a few days ago, and now the pressure is running 28-30. Definitely cause for concern as I have gone from 18 to 28 as my new "normal" pressure.
I have backwashed several times and today, I opened the filter and did the deep clean with the hose, with no improvement in the pressure reading. Still running around 28
Gauge returns to zero when turned off and runs around 5 on recirculate. Pressure from the returns is strong on both filter and recirculate modes.
I have researched this site and cannot find a fix for my issue. Of course, we are about to leave on vacation and I want to resolve this before we leave. Many thanks in advance for your assistance!
