Section 8: Plumbing System
Tank Heaters
Your recreation vehicle may be equipped with heaters for the fresh, gray, black water tanks.
These heaters will prevent water in the tanks and lines from freezing down to -11°F (-24°C)
(contingent on recreation vehicle setup).
The larger tank heaters are 120VAC and attach directly to the tanks. The thermostat con-
trolled tank heaters will cycle on at 44°F (7°C) and off at 64°F (18°C). All of the heaters are
controlled by a single ON/OFF switch that is typically located on the command center panel
or in the bathroom. The switch lights up red when ON and controls the heater circuit.
In order for the 120VAC tank heaters to be in operation, the recreation
vehicle MUST be hooked up to shore power or under generator power.
If the recreation vehicle is not operating on shore power or generator
power, the heaters will not operate. This can result in the tanks freez-
ing.
The red light on the command center tank switch does not necessarily
indicate that ALL heaters are operating; it is only a warning that the
heater circuit is ON.
The tank heater switch should be turned ON:
When liquid is present in the holding tanks and the outside temperature approach-
es and maintains freezing conditions 35°F (2°C) or colder.
The tank heater switch should be turned OFF:
When there is NO liquid present (tanks are empty).
When dumping the black and gray holding tanks and the drain pipes.
When fresh water tank and supply lines are empty or being drained for storage.
When the recreation vehicle is connected to city sewer and the gate valves are
open.
™ NOTE: Free draining is never recommended, especially in cold weather use.
When ambient temperatures rise and remain above freezing.
No maintenance on the heaters is required, only a periodic inspection for loose wires, dam-
age, etc. For additional detailed information, refer to the tank heater manufacturer's user
guide.
Toilet
Prior to using the sanitation system, it is strongly recommended to flush the toilet several
times to release sufficient water into the holding tank. Generally, more water is required only
when flushing solids.
The toilet system will perform better when water is run for ten to fifteen seconds after flush-
ing to ensure that the waste will proceed to the bottom of the tank.
If there is not a sufficient amount of water used during flushing, the waste materials may not
evacuate properly from the drain line to the tank. Clogged tanks and pipes could eventually
occur. For added convenience and better sanitation system performance, it is advisable to
always have four to six inches (10 - 15 cm) of water in the toilet. It is important to add
enough water to prevent solid waste buildup. The following guidelines will help to prevent
solid waste buildup.
