Ok, bought a house last year that had an existing pool which apparently was never kept up on by previous owner. My pool pump died this week and should be expecting a new one in the next day or 2 and I started the process of removing the old pump to make way for the new install. Thinking that the pipe connections would untwist apparently whom ever installed this equipment used putty/caulk every where with no screwable pvc fittings. I used a hacksaw to cut as close as I could to the old pump hoping to see it was threaded, which it was not. My question is what is the best method to remove the old pvc piping on the union that connects the pool cleaner and skimmer lines to the pump? Am I that screwed and may need to get a contractor to perform the install?
