Draining the H2O HTR and a COmplicated Thread
We don;t typically winterize here as it rarely gets cold enough long enough to need it. But we had a (rare) week long hard freeze here in the 20's at night.
I drained the water out of the H2O HTR by removing the anode. It wasn't leaking when I removed it but it was not particularly tight. The way I park the trailer close to the fence on the side of the house, I couldn't get it back in properly. It would only go in a couple of turns and then stop.
Yesterday I dragged the trailer out and had a look. The threads were calcified. I took a wire brush on my dremel and gently removed most of the deposts.
A little pipe thread compound and it went back in, nearly all the way. I refilled the water heater and there are no leaks.
While I was at it, I added some water to the tank since we are taking her out for NY Eve. No leaks in the traps, or anywhere else that I could find, so I guess we survived the freeze intact.
