So I am trying to find the right fittings and such to make a braided hose or tubing drain line permanently attached to the drain port on my travel trailer's water heater. I figure I need about 9" to 12" hose or tubing, a fitting to fit the actual drain port on the water heater, and a valve of some type at the other end. Why am I doing this? Because engineers are not technicians, and some engineer numb-nut saw fit to put the cheap nylon threaded drain plug behind the gas line and below the gas burner exhaust deflector, which makes accessing the drain plug a monumental PITA. Accessing the drain plug is one issue, but the cheap nylon drain plugs are too soft to use an open end or box end wrench. I have to use channel locks to remove the drain plug after removing the gas burner exhaust deflector. Needless to say this makes winterizing my RV water heater a pain. Any advice on what to make this with and where to get the parts? I tried Home Depot and it was a waste of time. Wish my Pops was still alive, he was a journeyman plumber for years and would have this project licked in about 5 minutes... FWIW, he did teach me a few things about basic plumbing (pipe sweating, different types of fittings, installing a faucet and sink, etc...) so I'm not a total newb, but getting the goods for this project is proving troublesome. Thanks in advance for any guidance you can provide!
