Draining The Fresh Water System
Water tanks may be drained through a valve located near the tank. A recreational vehicle
with a demand pressure pump system will have low-point drains attached to the water lines
(normally located near the water tank).
These low-point drains will release water in the supply lines by opening the valves and all
faucets. The water heater has its own drain plug. To drain the permanent fresh water holding
tank and supply lines:
1. Turn the water heater power OFF (turn o the electric and LP gas
switches).
2. Open all faucets, including the outside shower faucet (if so
equipped).
3. Open the “fresh tank drain” valve. All fresh water tanks can be
drained by one of two types of drain valves. A white plastic drain
is attached to the exterior wall or a valve located inside the RV ad-
jacent to the water tank (turn 45° to open or close).
