How to empty the hot water tank

We have a 2013 Rockwood 2608 ws and need some help on how to drain the hot water tank for storage tried to drain using bypass valve. The tank still won't empty. Can someone please tell me the steps to accomplish this task. Thanks

Hello and welcome to the forum. Make sure water us cool first. Go to the outside panel and remove it. (This will likely be a metal square panel on the side wall of your trailer) There will be an overflow valve to flip to bleed off the pressure. Once the pressure has bled off, then remove the drain plug/anode rod. Leave the overflow valve open while draining.

You don't use bypass to empty tank? The only way to drain is to remove anode is this correct?

Not sure what you mean when you stated you tried to drain via the bypass valve, which cannot be accomplished. There may be some terminology confusion.

If you have either a Suburban or Atwood water heater, you drain them in similar fashion.

For the Suburban brand, you pull the anode rod, which drains the heater:



For the Atwood, you just remove the plastic/nylon drain plug:

Now as far as bypass valves are concerned, these are usually located on the backside of the water heater, which you will have to gain access to from inside the RV. You may have to go thru a false cabinet, panel, etc to gain access. If you have the 3 valve system, then this is how you want them set, either for normal use or for winterization:

One more thing, VERY IMPORTANT. You stated you have a Suburban brand. if you have the dual powered source one (propane and electric heating element)...make doubly sure you have the electric heating element switch turned off before draining. If it is on and you are hooked (or later connect) to any form of shore power, it will burn up the element without water in the tank.

This pic below is what you want to avoid. You can see how the anode rod is removed, yet the electric switch is in the on position. You need to make sure yours is OFF, if so equipped, just to avoid the possibility of burning the element up.

Some rv's have the bypass valves on an outside storage compartment (they were locked away as wmtire described on my old zinger tt but are in my basement compartment on my sabre fiver). As he said, no you can't drain the tank by using the bypass valves. Also, if you are winterizing, make sure you drain your fresh water tank using the low point drains. Keep your water pump off while doing this do you don't burn the pump out (contrast me how I know that I've).
