Current through Register Vol. XLI, No. 28, July 12, 2024
3.1. An adequate and safe supply of water
				under pressure shall be provided to each mobile home lot. The source, treatment
				and distribution system shall be constructed and operated in accordance with
				the rules and regulations of the state department of health. Records should be
				kept of the location of water lines, valves, meters, connections and other
				appurtenances to facilitate repairs or inspections when necessary.
3.2. When feasible, water shall be obtained
				from an approved public water supply system in order to obtain the advantages
				of qualified supervision, which provides added assurance that the quality and
				quantity of water will be adequate at all times for domestic and firefighting
				purposes. Where public water supply systems are not available within a
				reasonable distance for extension to a mobile home development, the best
				available private water supply source should be developed.
3.3. All wells, springs, reservoirs,
				treatment and storage facilities and distribution systems shall be constructed
				in accordance with the publications, EW-98, "Water Supply Regulations"; EW-99,
				"Design Standards for Public Water Supply Systems"; and EG-6, "Permit
				Procedures and Design Requirements for Small Sewage and Water Systems", issued
				by the state department of health.
3.4. Riser Pipes
3.4.1. The location of the water riser pipe
				on the stand is of great importance. Two principles should be carefully
				considered. First, a location should be selected that is as close as possible
				to the service connection of the mobile home. This reduces long service runs,
				long heater tapes, and resultant high electric bills and waterline freezing.
				Second, there shall be a safe clearance (10 ft. minimum) between the water
				riser pipes and the sewer riser pipes. The ANSI Standard for Mobile Homes,
				A119.1-1971, specifies that the water inlet should be located as near as
				possible to a point 30 feet from the front of the mobile home and on the left
				(road side) of the center line. A good location for the water riser pipe is
				approximately 56 inches from the center line of the stand, measured across the
				mobile home stand, and 30 feet from the front edge of the stand. The front edge
				of the stand should coincide with the front wall of the mobile home.
3.4.2. The water service connection must
				utilize a riser pipe of at least 3/4" diameter, terminating at least 4 inches
				above the ground surface, surrounded and supported by sand backfill, and
				protected against freezing. The ground surface around the riser pipe should be
				graded so that it diverts surface drainage away from the connection.
3.4.3. A service box with a shutoff valve
				should be located in a convenient and accessible place near the riser pipe. The
				shutoff valve should be installed below the frostline. Stop and waste valves
				shall not be installed in an underground service line; a stop and waste valve
				is any valve that permits drainage through a port or drain hole provided in the
				valve.
3.4.4. The riser pipe outlet
				should be threaded so that a screw connection can be made between the outlet
				and the mobile home water piping system, and the outlet shall be plugged or
				capped when not in use. Each water service connection also should have a
				shutoff valve and a nonfreezing wall hydrant located on the water pipe outlet
				of the mobile home.
3.4.5. Flexible
				metallic tubing, such a cooper, is suggested for connecting the mobile home to
				the riser pipe because it provides an effective method of electrically
				grounding the mobile home to a metallic water supply system, and it also
				facilitates the use of electrical heater tapes, which can be used during cold
				weather to effectively control freezing.
