Section 8: Plumbing System
Fresh Water System
All water contains contaminant and mineral particles that can cause fresh water system
odors. Untreated well water is a major source of water system odors. The fresh water (po-
table water) system needs periodic sanitization to take care of all the components in the
plumbing system to discourage the growth of bacteria and other organisms that can con-
taminate the water supply.
Water Pressure Regulator (customer supplied)
Excessive pressure from the water supply source may be encountered in some parks, espe-
cially in mountain regions when using the fresh water inlet or black tank flush. Water pres -
sure regulators are available to protect your recreational vehicles plumbing system against
such high pressure.
Fresh Water Holding Tank
There may be several ways to fill the fresh water tank depending on the model. For details
of each method, refer to the Fresh Water Connections or the Utility Center sections. There
are plastic overflow tubes in the fresh water holding tank which allow water to flow out of
the water tank. Occasionally, you may see water coming from the overflow tubes when the
fresh water holding tank is filled. This is normal and can be a result of the recreation vehicle
being parked on an incline, or the motion caused by starting or stopping during travel.
City Water Fill
NOTE: If needed, sanitize the water system prior to travel
 DO NOT drink water deemed microbiologically unsafe or of unknown
quality.
 Never travel with full fresh, black or grey water holding tanks.
A water pressure regulator is recommended to prevent damage to the plumb-
ing system or components. To prevent damage when using the city water con-
nection, a 45 lb. (315 KPa) rated water pressure regulator is recommended.
 Do not cap, block or modify the fresh water tank overflow tubes in any
way. Enough water pressure can build up during the filling process to
damage the plumbing system if the overflow tubes are obstructed.
 Be careful not to overfill the fresh water holding tank. It can pressurize
the tank, causing leakage and water damage and void the warranty. DO
NOT leave the tank unattended while filling.
