Atwood water heater drain valve...

I would like to replace the water heater drain plug with a valve so I can drain it easily after each trip.

I went to a couple of home stores and could not find a simple nylon valve that would fit in the space provided.

The area is so cramped because of the lp line that it would have to be a short valve. I was thinking of using a nylon adapter that goes to a barbed fitting to a short hose. Then put some kind of valve on the end of the short extension.


Has anyone come up with a neat idea for this?

Home stores are not the place to look.

Go to an auto parts store and look for a radiator drain valve that will work, it will likely be brass, and there is no need for a hose.

Hmm...Since the tank is aluminum, would a brass plug cause a deterioration situation? I always thought you had to be careful with dissimilar metals. Hence the plastic drain plug in the aluminum tank.

Water heater drain valve

one of the camping mags I have has an anode rod that fits in the 6 gallon & it has a built in drain valve, in the center of the rod. That's what I'm going to be ordering ,when & if I ever get our "new unit back from the corrections center" at JC. On our last unit I picked up a valve from HD & put that in where the drain plug was located. I then attached a short plastic hose to drain the water out away from the unit. Worked great, but I like that anode rod thing, so will be going that way, with the new unit.
Best,

The way it is on mine there is a nylon plug with a threaded hole filling the hole in the heater and that has the brass radiator drain in that so no contact between the metals

Richard,

I like your idea about the drain. I think I should be able to make that work.

On the other hand, when I installed my atwood I used brass nipples on the water lines because I could not find nylon ones.

I did wrap them with teflon tape pretty good. Perhaps that will save me from the dissimilar metals problem?
