In some communities there are specific notification procedures prior to a planned water service interruption, which is a courtesy to others served in your building.

Another thing to plan for.

Call a couple of local plumbers, or ask your assoc. member for a local repair plumber's number. Describe what you have, 1, 2, 3 handle as well as the building.

It's likely to be $100+ parts and labor.

Someone familiar with the community will know the make of the faucet, which can save a shopping trip.
