Water Supply System:
All water for use in your home enters through one basic piping system. The supply line entering your home must be a minimum of 3/4" in diameter. The pipe riser from the underground water line is connected directly to this system that has been installed in accordance with the specification of the HUD standards.
If the local water pressure exceeds 80 PSI, a pressure regulator should be installed on your water line. Under no conditions should the water pressure entering your home exceed 80 PSI.
The area under the pipes should be checked occasionally for signs of leakage. If your home is located in a area where prolonged periods of freezing temperatures occur, the water supply line to your manufactured home should be installed below the frost line and the entire pipe riser above the frost line must be insulated. There are a number of insulating materials available with which to accomplish this. A thermostat controlled electric heating element, generally referred to as a "heat tape", may also be used. This will turn off the electricity when heat is not required to prevent freezing. Be sure that any heat tape installed on your home is listed "for use with a manufactured home" by Underwriters Laboratories, Inc.
When the heat tape is wrapped around the pipe and plugged into the "heat tape receptacle", provided within 24' of the fresh water inlet on your home, protection against freezing will be provided to the pipe even in the coldest weather (as long as the electricity is on). Electric current consumption is about equal to that of a 25 watt light bulb, if the exposed water line is not too long. Be sure that any heat tape installed on the water line is listed for use with manufactured homes.
