Odd thing happened yesterday. Preceding it, I noticed the kitchen sink
faucet was leaking a little so did what I've successfully done in the past
- turning each faucet on and off firmly about 50 times, which has stopped
leaks in the past. I have no idea how. I mention this in case it might
pertain to the next paragraph.

Any way, running the kitchen sink hot water shortly thereafter, the water
started running dirty. Looked like rust. I checked the bathroom, which is
next to the water heater, and the hot water was clear, so it wasn't the
water heater. I let it run for several minutes and it cleared up, and has
remained clear since.

Curious. Any guesses?

TIA



Turning it off and on caused the water to stop abruptly and loosed up
some crap that has been accumulating for a long time.

That is a fairly common procedure when blowing down a steam boiler so it
looses up and gets the solids floating so they can be flushed out.
