water tank using the gravity fill, and use your water pump to supply water.
The city water inlet connection is located in the front utility bay just behind the driver's side front tire.
Buy a new one and use it only for filling your tanks and connecting to city water. View any hose lying around a
campground with extreme skepticism, especially it there's a wastewater dump nearby. Large RVs use hoses to flush
their wastewater system.
To connect the Roadtrek's water system to an outside source:
•
• Turn the water pump off.
•
• Close the city tank fill valve by turning the handle to the vertical position.
•
• Close all interior faucets.
•
• Flush old water and any contaminants out of the water supply faucet.
•
• Connect your fresh water hose to the faucet.
•
• Attach your pressure regulator to the Roadtrek's city water connection.
•
• Attach a fresh water hose to the the pressure regulator.
•
• Slowly open the faucet of the city water source.
•
• The city water connection by-passes the water pump and fresh water tank. Therefore, the use of these items is not
necessary when connected directly to an external water source.
To disconnect the city water connection:
•
• Turn off the external water source.
•
• Open a faucet to relieve the pressure in the system. Failure to do so will not damage your vehicle, but may result in an
unexpected shower. The galley sink is a convenient place to do this.
•
• If you used the City valve to fill the tanks, close it.
•
• Remove the hose from the city water connection, and replace the cap on the fill connection.
