City Water

Your Roadtrek can operate in either fully self-contained mode, or can be connected to a water supply such as a campsite's faucet.
The city water connection is in the driver's side rearmost compartment. Unscrew the white plastic protective cap and connect your clean hose to the
water faucet and a water pressure regulator attached to this connection point. Turn the faucet on and check for leaks, tightening the connections as
necessary.
For more details, please refer to the HOWTO: Potable Water Use section.

Summer and Winter modes

The water system in your Roadtrek has an exterior and interior water tank. In summer mode (above freezing) both tanks can be used. In mildly sub-
freezing conditions, the exterior tank must be drained and the system set to winter mode. See the HOWTO: Summer and Winter Mode for a concise
description of how to operate your system in either mode. In temperatures lower than mildly sub-freezing, or any freezing temperatures when the
Roadtrek is not constantly heated, you must winterize.

Summer Use

In summer mode, both the interior and exterior tank are used to store fresh water. The tank isolator valve in the water line connecting the two tanks
is open, and water is drawn from the exterior tank by setting the tank selector valve to the exterior tank position. As water is used from this exterior
tank, the interior tank, which is positioned higher in the vehicle, drains into the exterior tank by gravity, thus providing you with full use of the
combined capacity of the two tanks. The valves to the outside shower are open, allowing use of that facility as well.

Winter Use

In winter mode, only the interior tank is used to store fresh water. The tank isolator valve in the water line connecting the two tanks is closed, and
the exterior tank is drained. The interior water tank has a capacity of approximately ten gallons, and this water is protected in moderate sub-freezing
conditions by the tank's position inside the heated vehicle. The valves in the water lines to the outside shower are closed, so it cannot be used, and
neither can the city water connection.
Again, please refer to the HOWTO: Summer and Winter Mode section for instructions on how to configure your water system in these modes.
