Section 8: Plumbing System
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 off 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. Methods to drain the fresh water
tank may vary by model. Fresh water tanks can be drained by one of
the following methods:

A white plastic drain attached to the exterior wall

A valve located inside the RV adjacent to the water tank (turn 45° to open or
close).

Pull the white “T” handle on the fresh water holding tank to drain the water
4. 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. The type of drain may vary by
model. You will have either an interior or exterior drain.
5. Interior drains: the drains will need to be operated from inside
the RV. Once the label is found on the exterior sidewall, the
drains will be found at a corresponding location in the interior.
6. Exterior drains: Open the “low point drains” by removing
the black screw on caps on the water lines (coming out from the
underbelly). The drains will typically need to be opened from outside the RV.
7. Drain the sink by removing the drain cap.
8. Turn ON the water pump and allow it to run as needed.
9. Open all faucets, including the outside shower faucet. Make sure the “water heater
bypass” valve is open.
10.
Operate the toilet flush lever until water stops flowing.
11.
If the RV water heater has bypass valves, set them to the BYPASS configuration (refer
to the
Water Heater Bypass
section).
12. Relieve the water pressure using the P&T valve BEFORE removing the water heater
drain plug. If there is any water pressure present, the water will spray out of the open-
ing when the drain plug is removed.
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..

Water Heater Bypass
Most models have a factory installed water heater bypass that enables you to avoid filling the
water heater with RV antifreeze. The 3-Valve Bypass is typically located in close proximity
to the water heater.
™
NOTE: In the 3-valve bypass diagram, valve D is the fresh water tank shut-
off. Valve E is used to introduce RV antifreeze into the lines when winterizing
the system and has a clear hose attached to it. See
Winterizing the Plumbing
System . Valves D & E are typically located near the water pump, which may
be under a dinette bench, kitchen island, or bed.
