I'm a bit of a plumbing neophyte. I'm trying to add a by-pass to my water heater. It has plastic tubing with some odd fittings which use barbed ends with threaded nuts. I figure I would rip it all out and replace it with those easy to use "quick connect" fittings. Well... turns out my hose is 5/8" OD and seems most all fittings don't come in that size. I did see some fittings on West Marine's site that claim to be 5/8" OD. But they are made by Seatech and oddly enough, Seatech's web site doesn't show any 5/8" fittings. Any guidance on how best to proceed would be appreciated.
