Hi all, found this forum, thought maybe a few experts here could help out.
When it first start, everything seems to be working very well -- back pressure is about 15psi. After 30 minutes or so, the back pressure (as deteriorates to near zero. This happens regardless of how I configure the skimmers and/or pool vac. I have even run it with the pool vac inlet full open and it happens.
At first I thought it was an issue with the pump -- so detached it and cleaned it up but that didn't help (its a 1 yr old pump, too). Backflushed and cleaned out the sand filter as well with no change.
There does seem to be more air bubbles in the lines -- maybe I have a in-line air leak?
I have quite a few mesquite trees dropping debris into the pool, so this may be some kind of debris issue, but if it was a clog, why would the flow rate / pressure start off fine?
Thanks in advance for any help you can offer...
