Hi, bought a home that came with a 1999 Coleman Spa. The previous owner did not drain it and a 1 1/2" PVC pipe froze up and broke along about a 6 foot run. No big deal. BUT along that run is five 1 1/2" T fittings that tie into flexible PVC tubing. And a female 3/4 inch is too small and a 1" female PVC is too big???!!! I figured spas had their own format, So I ordered 1 1/2 T's with a 1" opening for the lines. They are too big. The lines seems to match the outside diameter of a standard 3/4" PVC fitting. But no female openings are designed for external diameter fittings; only internal. So how what "T" do I use and where do I get it? The local MAxx/Coleman dealer had the 3/4" but they do not work.
