trying to close an old pool
I'm hoping someone can help me. I have an old gunnite pool. It's in great shape and all of the systems seem to work fine. This year I decided to start closing the pool myself. However, all of the instructions I can find are for newer pools with side skimmers. My system has a bottom drain and two return jets that are about two feet down from the pool deck. There doesn't seem to be a way to cap these and when I blow the lines out with my compressor and then turn the compressor off, the lines simply fill back up with water. And without capping those lines off, the line to the bottom drain doesn't empty. Does anyone have idea for how to cap or stop these return jets on the side wall?
Thanks to anyone who can help!
