§ 9-217. Water distribution.

Plans shall be submitted by the owner of a moorage to the building official showing complete details of the water service and piping system; all shall be accompanied by calculations to verify the adequacy of such system to meet demands of the moorage. The design of such system shall comply with the other applicable sections of this chapter and shall meet the requirements of the following:

(1)

Plans. Plans shall show the size and location of each water meter and the type, size and location of all required water service backflow prevention devices.

(2)

Materials. The use of nonmetallic or exposed steel piping on docks, floats, ramps or similar moorage facilities will not be permitted. Exposed copper tubing placed on these facilities shall be joined by brazing or by other equivalent methods. Flexible water supply connections to or located on such facilities shall be approved heavy-duty type and each hose bib serving such facilities shall be an approved type incorporating a spring loaded check valve.

(3)

Flexible water supply connections. Flexible water supply connections shall be approved heavy-duty type and shall be installed and supported so that at all times they will be above the moorage basin water level.

(4)

Backflow prevention devices. Each hose bib serving a dock, float, ramp or similar moorage facility shall be equipped with an approved spring loaded check valve. Each floating home or vessel which uses a pump or equipment which could cause a cross connection potential shall have a separate approved backflow prevention device over and above the protection provided in the moorage piping.

(5)

Temperature and pressure relief valves. A combination temperature and pressure relief valve shall be provided on all water heaters.

(6)

Wet standpipes (fire lines). Water lines supplying wet standpipes must be capable of supplying fifty (50) gallons per minute and maintain a residual pressure of thirty (30) pounds per square inch at the hose connection based on the minimum water supply. No fire pump inlet connection will be permitted on any wet standpipe system which is connected to a potable water system.
