All of the (above ground) plumbing on my AGP is 1-1/2" flexi-hose but I'm looking to hard-pipe a segment of the return line to support an in-line chlorinator.
Couldn't find a particular 1-1/2" PVC fitting I needed in the local pool store, but found the ABS (black) equivalent in a plumbing store. Nipped back to the pool store just to double-check that a stop-valve I was planning to use (with male NPT thread) fitted OK, which it did. Store guy comes over, I explain what I intend to do, and he says you cant use ABS fittings. Why? Because they use different cement. I said, the only thing I'm gluing is the Sch 40 pipe (black) and ABS fittings, and for that I was planning to use the same primer-cement combo - Sluyter 3 primer (clear) and PVC/ABS Transition Solvent Cement (white) - that I use on all Sh 40 plumbing around the home. I asked if it was something to do with the pressure-vaccuum rating, or maybe chlorine-resistance of PVC/ABS welds, and he says, no, as I told you, it's because they use different cement and you should use only PVC fittings.
Strange conversation, but is he correct?
