Draining Water Heater

Hi All: First of all thank you to Skinnyp who posted questions about the water heater anode on June 16. We have only had our trailer for a little more than a year as due to COVID, it was 1/2 finished and in storage at ETI for awhile before being sold to us! We are storing the trailer for a couple of months before our August travels, and need to drain the water heater. So, we have 2 more water heater questions:
1) First of all, we have a thick mattress in our 2020 Escape 17B, that covers the seat cabinets, making it quite difficult to get to the bypass valves to properly bypass the water system in order to drain the heater. IF we drain the entire water system in the trailer (except maybe 1/2 gallon so as not to burn up the pump), and open the water heater drain-plug (anode rod opening) to drain the heater afterwards, would we really need to position the bypass valves to “water heater drain”?
2) We are having great difficulty in opening the drain plug by loosening the washer/gasket that is at the anode rod opening. Is there a special wrench that we need to open it? None of our wrenches are working!
Any ideas and hints will be appreciated.

Anode removal

Get a good inch and a sixteenth socket (6 sided socket if possible) that fits a one half inch breaker bar. and 3 or 6 inch extension. That combo will allow you to put adequate force to turn the Anode Rod out ( counter clockwise). When you first get the socket on the anode nut try slightly tightening it. Then reverse the pull on the breaker bar. It will most likely come loose. It’s kind of spooky to reccomend using an impact wrench on the socket but it has been done. Start with a low torque and work up. That steady tapping of the wrench will loosen a lot of things.. when you reassemble, put three or four wraps of teflon tape on the threads and it will be a lot easier the next time. Make sure your water heater has been off and the water isn’t hot and let the pressure off by having the pump off and opening the hot water tap till the water quits running.

It would be your choice whether or not you’d want to use a little liquid wrench ease on the threads. If younsint use much, wipe it off the threads once the anode is out and wash the anode with hot soap and water I don’t think there’s a problem. Others may not like the idea of it.
Remember , easy does it.

Additionally FlowerandFrog, You do not need to touch the ByPass Valves at all. Simply follow the procedure outlined by Iowa Dave, and this will completely drain the hot water heater. You may notice some white chalky magnesium particles flush out with the water, and this is expected. Use a hose nozzle to flush out any other residue on the bottom of the tank, and let drain. If the anode looks to be in good condition, wrap with Teflon tape and reinstall as Dave said. No more than 15-20 lbs. pressure on tightening the anode! Good Luck!

Bypass is only used to prevent filling the water heater with antifreeze when winterizing.

Good and bad anode:

You can get years out of an anode, or months, depending on the water. In BC water is soft and anodes last a long time. This one is six years old.

When you flush out the tank with a hose lots of flakes will come flowing out as was stated. When the water stops
Running out after you flush it, put your finger in the hole and feel for some “sand”
Just inside of the tank under the rim. Flick that back into the tank and rinse again so you don’t have a wet spot and so none of the grit gets in the threads. ( yes I am at times OCD.) then as Habberdabber says put a one inch wide strip of old bath towel that hangs out and will wick the tank dry.
