where do i drain the freshwater tank on a switch 501
Hello, There are two options to drain your fresh water tank. First is to turn on the taps and drain the freshwater tank via the grey water tank. The second is to wriggle under the motorhome and remove the bung in the tank or tanks. Once you are satisfied that the tank (tanks) are empty replace the bung ad secure with plumbing tape.
