Property Owner Responsibility Internally

Excluding the Street Side Shut Off Valve (aka first valve) and the Water Meter, the Property Owner is responsible for all other plumbing appurtenances including the Owner Side Shut Off Valve (aka second valve) and Pressure Reducing Valve (PRV).

The Property Owner is also responsible to protect the Street Side Shut Off Valve and Water Meter from damage, including freezing, vandalism, theft, or other possible causes. Frozen or damaged meters will result in replacement costs billed directly to the Property Owner.

The Owner Side Shut Off Valve (aka second valve) is used to shut off the water coming into the building after the meter.

The Pressure Reducing Valve (PRV) is a bell shaped device used to reduce the street side pressure coming into the building to a level low enough to protect the interior plumbing components. Depending on the year that the PRV was initially installed it may be positioned before or after the meter, in either case the Property Owner owns and is responsible for maintenance, repairs and replacement of Pressure Reducing Valve’s.

Persons or entities seeking to perform work involving the District’s drinking water distribution system including but not limited to water main/service pipe installation, excavation, repair, relocation, or disconnection on both public and private ways/parcels must hold or acquire a valid Water Contractor License issued by the Sudbury Water District.
