Section 12-F608. PROTECTION OF POTABLE WATER SUPPLY

 

Strike Section 608.16.4 of the International Plumbing Code in its entirety and insert new Section 608.16.4 in the Plumbing Code in its place to read as follows:

 

608.16.4 Connections to automatic fire sprinkler systems and standpipe systems. The potable water supply to automatic fire sprinkler and standpipe systems shall be protected against backflow by one of the following methods:

 

1. If the systems contain no chemical additives, by a double check backflow prevention assembly conforming to ASSE 1015 or by a double check detector fire protection backflow prevention assembly conforming to ASSE 1048.

 

2. If either system contains chemical additives, by a reduced pressure principle fire protection backflow preventer conforming to ASSE 1013 or by a reduced pressure detector fire protection backflow prevention assembly conforming to ASSE 1047.

 

Exception:  Where systems are installed as a portion of the water distribution system in accordance with the requirements of this code and are not provided with a fire department connection, separate backflow protection of the water supply system from the fire suppression system shall not be required.

 

Insert new Section 608.18 in the Plumbing Code to read as follows:

 

608.18 Fire hydrant use connections.  Connection to a fire hydrant for any use other than firefighting operations shall require pre-approval by DC Water, shall be metered and shall be protected against backflow in accordance with this section.  The connection shall include a reduced pressure principle backflow preventer conforming to ASSE 1013, suitable for high-hazard applications, which shall carry a current inspection tag less than six months old.  The assembly shall be installed within 10 feet (3048 mm) of the hydrant water meter and ahead of any water outlet.
