Early this season I had the winterization pipe attached to one of the return jets to use for aeration and double as a fountain for the kids and somebody turned it to the point it got stuck. I've just left it all season, but now winter closing is on the mind and I need to get it off to be able to close the pool - currently it's stuck almost straight horizontal.
I've tried wrenches and oil filter clamps, had one person hold one on the outside border of the return piping while I try the PVC from inside the pool and it won't budge. I'm sure I'm turning the right way because I took others off to double-check the thread direction. It's a male threaded 1 1/2" going into the female threaded that's glued to the buried pipe. I still try to be careful because I don't want to snap the pipe in the wall, but have put quite a bit of pressure to no avail. The pipe is about a foot under water and even to the point I'd drain the pool for winter (just below the skimmers), it'd still completely cover the pipe.
Any ideas on how to get it off? My only thought is to cut it, but not sure the best way to do that without risking damage to the female thread of the wall pipe, especially as it's under water, so power tools are not an option.
