Question I live in a 5-unit condo in New York City. My upstairs bathroom has two handles under the sink which I know controls the water supply to the sink. There are no handles near the stall shower. Do these handles also control the water to the shower? In other words, do the handles under the sink control the water supply to the bathroom? Thanks.
Answer Hi Ken,
No they don't. Some multiunit buildings have local "apartment stops" as part of the valve that are right under the regular handles. They are usually behind the trim plate. They are "screw driver" type shut offs that do not have actually handles. If there are no apartment stops, the building or that riser needs to be shut off by building management.
Multistory buildings usually have their plumbing designed in "stacks" and the water supply serves all the units on all floors on that particular stack.
Pretty much any residential plumbing questions. For "item specific" details such as a specific model of fixture, I will need to research and there may not be any useful information available.
Note: I live and work in Southern California. We do not, as a rule, use hot water or steam heating systems, oil fired boilers or private water wells so my knowledge in those areas is pretty limited. There are others here on AllExerts that can probably answer those questions better.
