BCAB #1454 - Pressure Reducing Valve, Sentence 6.3.3.(1), B.C. Plumbing Code
December 15, 1997
Re: Pressure Reducing Valve, Sentence 6.3.3.(1), B.C. Plumbing Code
The project in question is a single dwelling supplied with potable water from a municipal water main.
Reason for Appeal
Sentence 6.3.3.(1) requires that where the static pressure may exceed 550kPa a pressure reducing valve must be installed to limit the static pressure to not more than 550 kPa in areas that may be occupied.
The appellant contends that the pressure tested at an exterior faucet by municipal staff was only 427 kPa so a pressure reducing valve should not be required. The appellant also questions why the pressure reducing valve that was installed was approved even though a hose bib and rough-in for a future bathroom are up stream of the valve?
Building Official's Position
The building official contends that a municipal bylaw requires the installation of a pressure reducing valve because the municipality considers the static pressure could exceed 550 kPa. As to the location of the valve the building official considers it is acceptable to allow a hose bib up stream and the bathroom rough-in would be required to be down stream when a plumbing permit is issued to install the bathroom plumbing.
Appeal Board Decision #1454
It is the determination of the Board that because the static pressure could exceed 550 kPa a pressure reducing valve is required. Regarding the location of the valve the Board did not consider that a dispute existed because the location has been approved by the building official.
