I have a Paddock IG pool, 12.5k gal, has five returns. Two on deep end, one each side and one by steps in shallow end. The return right in front of the drain basket is not returning. The eyeball and lock ring are off to make sure it was not the eyeball. Nothing is coming out. ??
The return by the steps causes the filter pressure to rise to about 19-20 psi with the eyeball in. When I took over this house, there was no eyeball in it, and pressure was about 12psi. As soon as I put an eyeball in it, the pressure goes to 19-20psi.?
Filter has new sand as of last July. Have backflushed as of this morning.
Any suggestions to either challenge would be greatly appreciated.
