The pool, Bestway 14x42 Metal Frame with 1.25" nipple hose fittings and small cartridge pump. Now that I have all of my needed Intex parts, I plan to install our sand filter this weekend. I will be cutting the liner to fit the Intex large fittings (three of them). Do I need to drain the whole pool to relieve stress on the liner while installing these? I want to drain to just below the fitting levels, but, am having nightmares about marking the pool, then it blowing out as soon as the knife makes the first incision. What have those of you who have been through this done?
One other question, I have not yet purchased the PVC parts needed. I'll be making my Intex adapters using the Dura brand PVC spa bushings, which will allow me to go with either 1.5", or 1.25" plumbing. The filter is the Intex 14", 2650 GPH sand filter. Which size would be best to use?
