Draininig the hot water tank

We will not be using the RV for a couple of months and I have drained all the tanks except the hot water tank. I see a white plug when looking at the tank from the outside compartment. Do i unscrew it to drain that tank?


Thanks again!

Yes, that will work. Either an 11/16" or 13/16" combination wrench will fit the plug. On some MH's opening the two low point drains will also drain the hot water heater. Don't forget to open the pressure relief valve on the HWH when you drain it. When you are draining the HWH, stand back if it's full...

As obvious as it sounds: Make sure the contents are cold before draining.

You don't want to have a contribution to the "bonehead mistakes" thread.

After pulling the drain plug you can also open the presure releif valve (tab) toward the top of the water heater. This pulls air into the tank letting the water pour out faster instead of glugging out like a pop bottle turned upside down.

If you have used the water heater a lot you may get sediment and/or crud in the bottom.

There are little "wands" that attach to hoses and have bent tips to flush out the bottom of the tank. They do the same job as the wands that you put down the toilet to flush out the bottom of the black tank.

Cost is about $10 or less.

There replacement plugs if yours leaks when you put it back in.

If you don't have electric water heating in addition to the gas system there is an electric system that uses the same hole to install a water heater element. I have one, not as good as factory but works reasonable well.

That drain you see on the driver's side is probably the fresh water tank drain.

The low pint drains are usually inside one of the rear compartments, there should be two chrome valves, side by side, one for hot, one for cold. These are used to drain down all the water lines in the coach and possibly the water heater.

I know on my coach, I have to take out the tank plug, the low point drains don't drain the water heater.
