S-i-l and brother and I managed our respective bathroom (and house) renovations by using the facilities next door...that won't work this time.

And I just tested and have water! Lots of air in the line, of course (cats are annoyed at the spitting sounds of the faucets), some mud, but it's back. Have started the dishwasher, figuring that the supplemental heater and the detergent will conquer any contaminants in the supply line.
