See the output port on the Jandy valve in the photo? I need to cut everything off from that Tee downward and put a 2" union on it so I can repipe all the way to the pump. My question is, after i cut the Tee off, that will leave only about a half inch of pipe to glue a 2 inch union onto. Is that enough? If not, I'll have to buy a new Jandy valve and start from the ground up.
