Puzzle - can anyone shed light on this?
We have no problem with the hot water in the house except in the bathroom
furthest from the hot water heater, and then only in the tub and not the
handbasin. Anytime hot water is turned on in the tub, the water runs black
then finally clears. Since it is the guest bathroom, it is something I'd
like to solve. Any thoughts, anyone?

Black water usually means a rubber faucet washer deteriorating.
But it might also be caused by corrosion of a galv iron nipple
in the supply or in the tub spout connection to the faucet.
