My old, achy bones are getting tired of lugging 100 lbs of chlorine from the pool store every few weeks during the summer and I'm going to break down and get an SWG. I'm looking at the Circupool RJ-60 PLUS. I've got everything figured out except the flow switch: how the heck do you install that into existing plumbing? It looks like a standard PVC coupling connection-wise. That means it's literally impossible to cut a length from existing plumbing and install it. The way my plumbing is set up there is no possibility of using some elbows to make the install possible. Is my only option to rig some unions onto that sucker? That could be challenging in the short length of pipe I have. Hopefully I'm just missing something.
