Water Systems
Fresh Water System
Potable (drinking) water is supplied throughout your motorhome from the fresh water tank
or from a connection to an outside water source attached to the city water ll. When using
the fresh water tank, water is pressurized and travels through the water lines by means of the
water pump. When utilizing an exterior water source, such as a campsite water spigot, the
water pump is not needed as the campsite water source is already pressurized and will ow
through the water supply lines.
Potable Water Hose
We recommend purchasing and keeping sanitized a water hose whose sole function is for use
with your potable water system. We do not recommend using the same water hose for potable
water, maintenance, or sewer system cleanup, etc.
Connecting to an Exterior Water Fill
1. Set your water heater bypass valves to the correct position listed on your water system
label.
2. Remove the cap from the fresh water inlet on the side of the motorhome.
3. Attach one end of your potable (drinking) water hose to the outside source of water.
4. Connect the other end of the hose to the motorhome's city water inlet.
5. Turn ON the outside source of water. Gradually open the hot and cold water at the sinks
and tub to clear air from the lines. Close the faucets when the water is owing freely.
To Disconnect From the Outside Water Source
1. Turn OFF the outside source of water.
2. Disconnect your potable water hose from the supply valve and the fresh water inlet.
3. Remove the water hose and store.
4. Reinstall the cap on the fresh water inlet.
Typical city water fill
NOTE: Disconnect from the fresh water
inlet or city water fill if leaving your
motorhome for an extended period longer
than a few hours.
