I have an odd problem.
Recently got my skimmer basket and skimmer line replaced. Once it was ready I started trying to get the pump filter up and running.
When pump in on recirculate I have no problems. Pump can run for days without losing suction.
When i put pump on filter is when I have issues. Starts off with really low pressure. (2-3psi) Then the pressure slowly climbs up to about 10 over the course of about 2 hours. It stays at 10 psi for about 3-4 more hours then looses suction and stops pulling water in from skimmer line or main drain.
Here is what I have done.
1. Took apart filter and clean out filters. Then back washed for about 5 minutes.
2. Made sure skimmer baskets are clean.
3. Let air out of filter (isn't much air in the filter. )
4. Same thing happens if It set to skimmer line only of half / half skimmer main drain.
Not sure where to look yet. Appreciate any help.
