Mainly posting so I don't chicken out when it comes time to cut my liner, with my wife breathing down my neck "Honey, are you sure this is going to work and you aren't going to ruin the pool you just spent all week getting in perfect condition??"
My issue is that my plunger valve tends to work its way off of the rubber inner sleeve on the return, after I upgraded from the tiny A cartridge type pump/filter that comes with the 15' Intex metal frame pool to the 2650 GPH sand filter.
I am about to go on vacation and I'm scared that it will come off while I'm away and all my hard work will be ruined.
I will document the process - win or lose - with lots of pictures. Stay tuned!
