odd thing about my pool.
It skims well (after adjusting jets of course) but I noticed that the water level of the pool must be
at least 1/4" ABOVE the middle markings of the skimmer or it vortexes and sucks air every 10 seconds.
If the water level is at the middle mark it has this problem. Above that causes no problem.
Odd since most skimmers have those markings as the ideal fill level for skimming action.
I have a 1.5 hp superpump and wonder if it might be part of the issue as it seems over kill for my pool volume.
If I vacuum without an inlet regulator (it draws in a slight amount of water with an adjustable ring) between
the skimmer inlet and the vac hose, my pump makes a straining sound which in other threads ive seen here
may again indicate too much hp.
or did the builders just install my skimmer too high?
This is more of a curiosity than problem since I just make sure to top up if the water level ever gets
close to the skimmer mid line.
