I am replacing my Hayward T Cell -15 with a Pool Pilot Nano +and need to redo the plumbing. Unfortunately the union for the T cell is right next to the 3 way valve and I can't find a fitting to attach to the Hayward union, non standard threads. I was hoping to buy a GLX-CELL-Pipe and cut the pipe in half and connect a standard 2 inch PVC fitting to the pipe and continue the Nano+ installation. Does anyone know if the pipe is a standard size? If yes what size is it?
