Hello, first post here so i dont even know if its in the right place until I get fully registered or however this works.
Anyways, i have an inground pool with a sand filter, and was wondering if its normal to have air bubbles in the basket just before the pump.
It seems every 4-5 days the pump pressure goes up and nothing comes out the returns unless i backwash and then all seems normal again, with those bubbles in the basket area.
It is spring, so there is more pollen and dust/dirt than normal, but overall the amount of leaves and stuff has decreased to the point that there is nothing significant. Would it be just the filter collecting all the debris thats causing nothing to come out the returns?
On a side note, i just had one of the skimmer elbows repaired for a leak maybe 3-4 weeks ago. Would it be possible for air to enter the system through a "faulty repair"? but would that mean water could also leak out? Pool water level is stable and not dropping (it would drop an inch a week before the repair).
Any direction here would be appreciated, thanks.
