to the exterior wall or a valve located inside the RV adjacent
to the water tank (turn 45° to open or close).
4. Open the “low point drains” by turning, then pulling the han-
dles up. They 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 drains will need to be op-
erated 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.
5. Drain the sink by removing the drain cap.
6. Turn ON the water pump and allow it to run as needed.
7. If the RV water heater has bypass valves, set them to the BYPASS configuration (refer
to the Water Heater Bypass section).
8. Operate the toilet flush lever until water stops flowing.
9. 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.
When you are finished draining the fresh water system, reverse these steps and dump the
grey and black water holding tanks. It is normal for some liquid to remain in the fresh water
tank after drainage procedure.

Sanitizing/Winterizing the Plumbing System (No
Utility Center)
Water Heater Bypass(2 Valves)
Most floor plans have a factory installed water heater bypass that enables you to avoid filling
the water heater with RV antifreeze. Bypass valves are typically located in close proximity
to the water heater. Outside utility centers (if so equipped) operate differently than a factory
installed bypass system. Refer to the Outside Utility Center section for details.
Operation
Normal Mode : operation 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: operation 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.
When to sanitize:
 When your recreation vehicle is new.
 At the beginning and end of each season.
 When the water system becomes contaminated or every three months of use.
NOTE: : Valve D is the suction (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 equipped) is a shutoff valve for the fresh
water tank. Valves D & E are typically located at the water pump.
