Grey Water Tank
To keep the grey water tank fresh and remove smells it should be emptied and flushed regularly. Tank fresheners are
available in various brands and are highly recommended. The grey water tank is emptied via the valve on the near to
curb side of the trailer.
Fresh Water Tanks
When used for drinking water regular tank maintenance is vital. By regularly using a proprietary Tank Cleaner you will
reduce or eliminate bacteria and after taste. Always fill your tanks using a potable water grade hose. Fitting a filter that
removes smell, taste and bacteria is highly recommended.
Selecting the Supply tank
Valves to select the supply tank on trailer models with multiple freshwater tanks are beneath the trailer on the near to
curb side beneath the water pump location.
Connecting to City Water
The city water connection is located behind the filler cap panel shown below.
