The hot water heater hose parts. . . I was going to take a picture of each part before I put it together, but before I could, DH grabbed it all and put it together. I think he was jealous of all the time I spent working on the trailer.
So it's the plumbing hose, and I got 1/2" connections on each end. The original mod I saw had one end descending to 3/8", but the valve I found was 1/2", so I got the 1/2" on each end. I got a 1/4 turn valve (easier than the multiple turn). And between the hose and the hot water heater was a 1/2" plastic plumbing nipple (
looked like this but was plastic).
Plumbers tape between all the connections and put it all together. Tested for leaks. . . no problems. Very easy mod and so useful.
