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.
Interior drains: the drains will need to be operated from in-
side the RV. Once the label is found on the exterior sidewall,
the drains will be found at a corresponding location in the
interior.
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.
5.
Drain the sink by removing the drain cap.
6.
Turn ON the water pump and allow it to run as needed.
7.
Open all faucets, including the outside shower faucet. Make sure the "water heater
bypass" valve is open.
Operate the toilet flush lever until water stops flowing.
8.
If the RV water heater has bypass valves, set them to the BYPASS configuration (refer
9.
to the Water Heater Bypass section).
10. 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 opening
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 floor plans have a factory installed water heater bypass that enables you to avoid filling
the water heater with sanitizer or antifreeze. Bypass valves are typically located in close
proximity to the water heater.
Operation
Normal Mode: allows water to flow into the water heater. Both hot and cold bypass valve
handles should be pointed toward the water heater connections.
Bypass Mode: diverts the flow of water around the water heater keeping water out of the
water heater. Hot water bypass valve handle (B) should point inline with the hot water outlet
line. Cold water bypass valve handle (A) should point inline with the cold water inlet line.
™ NOTE: Valve D is the siphon valve that has the clear hose attached to it for
siphoning in antifreeze, sanitizer or fresh water from an external container.
Valve E (if so equipped) is a shutoff valve for the fresh water tank. Valves D
& E are typically located at the water pump.
