Friend just called. Water in clothes washer.
It fully drained yesterday.
But now a few inches of water is in the tub.
He suspects a problem with his drain and put some drain cleaner down the pipe.
I suspect a leaking clothes washer water valve.
Suggested he shut off the HOT water line since it is less likely that sediment would get out the top of his water heater and get stuck in the clothes washer valve.
Then we will know if it is the COLD water valve and not need to take apart both valves.
Should one shut off the water when done washing?
I'd take an educated guess - but I'm unqualified.
It ain't just soot, it's paydirt.
