I'm getting ready to do this once I get the correct p/n shipped. My pump booklet has the wrong p/n in it.
I may (probably will ) have to cut the piping on the output side so as to unscrew the old housing...however...can you take a look at the attached pic and tell me if the threaded connection going into the multi port valve on the left will unscrew? Are they typically connected without being glued to the pipe? If so then I will be able to remove the housing without cutting piping. My guess is that the threaded coupling is glued onto the 2 inch pipe. I'm assuming that is the easiest / cheapest way of connecting the threaded assy to the piping. Just a long shot. The image is upside down, not sure why that is.
