DRAINING THE FRESH WATER SYSTEM
Fresh water tanks may be drained through a valve located near the
tank. An RV 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.
Make sure the RV is level.
2.
Disconnect the water line from the City Water
connector on the RV (if connected).
3.
Turn the water heater power OFF (turn off the
electric and LP gas switches).
4.
Open all faucets, including the outside shower
faucet (if equipped)
5.
Open the "fresh tank drain" valve. Depending on the model, fresh
water tanks can be drained by one of the following methods:
•
A white plastic drain attached to the exterior wall, beneath the
skirting.
•
Pull the white "T" handle on the fresh water holding tank to
drain the water (Located near black and grey tank "T"
handles).
6.
Low point drains are installed at the lowest
point of the water lines. A label is placed
on the outside of the RV to indicate where
the drains are located. Open the "low point
drains" by turning the valves on the water
lines (coming out from the underbelly).
7.
Turn ON the water pump and allow it to run
as needed.
8.
Operate the toilet flush lever until water stops flowing.
9.
If the RV water heater has bypass valves, set them to the
BYPASS configuration (refer to "Tank Versus On Demand Water
Heaters" on page 75).
10. Relieve the water pressure using the T&P
(temperature and pressure) relief valve on
the water heater by lifting the valve lever
BEFORE removing the water heater drain
plug. If the water heater was on beforehand,
any water coming from the valve may be hot,
so use caution. If pressure is not relieved,
the water will spray out when the drain plug
is removed. Once pressure is released, remove the drain plug.
It is normal for some liquid to remain in the fresh water tank after
drainage procedure. When you are finished draining the fresh water
system, reverse these steps, and dump the grey and black water
holding tanks at an appropriate facility or according to local public
codes.
