Board members and property managers must know the location of plumbing shutoff valves for every property they manage so that accurate instructions can be provided to plumbers. Shutoff valves may affect a single unit, a stack of units, or an entire building.

Where plumbing shutoff valves affect more than one unit, boards should determine the cost of converting the building to individual shutoff valves. Individual shutoff valves eliminate extreme inconvenience and time for board members, owners, and management.
