After a difficult week here in the tropic wetlands of philadelphia suburbs, my pool level is too high. I have also noticed my CH creeping up (420 today). I do not know how to drain water from the pool using existing system. Can anyone help? We have a newly installed (opened mem day this year), 36K gallon inground gunnite 46 x 27 free form pool, with hayward goldline prologic SWG/pump, two skimmers. I have a valve that can shut off skimmers, and be open only to pool main drain, as well as a clear cover on pump i can see water washing through when pump is running (I clean basket in it regularly). Help please! Thanks!
