WATER AND PLUMBING SYSTEM

Water Supply

Your motorhome is designed with fresh water, grey
water, and black water systems, and the associated
plumbing to handle all of the water and waste water
requirements.
Review this section carefully to understand each
system and how they function together.

Fresh Water System

The following two sources of fresh water supply your
motorhome's sink, shower, toilet and water heater:
o A fresh water tank located inside your
motorhome.
o A "City Water" connection that supplies
water through a hose.
The water system built into your motorhome
provides full service similar to the system used in
your home.
A 12-Volt DC self-priming pump draws water from
the fresh water storage tank to all the cold-water
faucets and the water heater.
An automatic pressure switch, located inside the
water pump, maintains positive line pressure.
The city water connection and water fill selector
valve are located in the rear utility center.
