Well, it's a home day today.
I went to take a nice, long, hot bath last night. Tub filled halfway before the hot water ran out. We know what that means--roughly.
Checked the resistance on the elements--12 Ohm, so fine. Bottom element is getting juice, top one not. Might be because the water is already hot, so I'll drain the tank--it's been a while, anyway.
Run back to the shop for tools and a garden hose. Hook the hose up to the water heater and open drain--nothing. Of course, our lovely hard water has completely clogged the outlet. Run back to the shop for the portable compressor. Try blowing the drain clear--nothing.
Give up and have a nice lunch and a beer. Think it over. Back to the shop again for a garden hose shut-off valve and a *** changer. Hook hose up to the hose bib below the kitchen window and let the hose run into the water heater tank for couple of minutes--until I see water coming out of the kitchen sink faucet. Victory!
Tank is draining right now. I gave it a few good good flushes and brought some unneeded tools back to the shop. Once the tank is empty, I'll refill it and then check to see if the top thermostat is calling for heat when the water is cold. Hopefully, I can find a thermostat for a twenty-year old water heater in town.
Back to the cabin....
