I de-winterized on Friday. Too cold to do it any sooner. We left on vacation Sunday morning. When I attempted to fill the Suburban hot water tank Friday, I would keep trying the pressure relief valve to see if water was in the tank. The PR valve never released any water. After about an hour I began to suspect the the valve was not functioning and removed the anode rod and found that the tank was full of water. I believe the PR valve has failed. I had no time to replace the valve before we left.
When we got to our CG monday I hooked up to the CG water supply and shore power. I set the hot water tank for electric. Monday evening I took a nice warm shower but when my wife went to shower several hours later she had only cold water. (I heard about that!) I was not running the pump because I am on the CG water system. I suspect that we drained the HW tank empty.
1) Is it possible that the hot water tank did not fill without the pump because of a defective PR valve? I'm pretty sure I burned the heating element. Today I checked the "reset" elements and they appear undamaged.
2) I wanted to turn the electric switch off and just use propane. I could hardly move the switch. Is there some way to damage the switch if the heating element is burned out?
Because of this forum I have learned how to replace the heating element. I don't understand why the switch will barely budge. The propane heating is working fine.
Your thoughts would be appreciated. Thank you.
