SECTION 8 - PLUMBING SYSTEMS
Some solution may remain in the water heater and will be flushed in the
following steps:
12. Fill the fresh water system completely full using clean (potable) water.
13. Then, drain the fresh water system (see Draining the fresh water system).
NOTE: If a chlorine taste lingers in the water, flush the water system with a
solution consisting of one-quart vinegar to five gallons of clean water. Re-flush as
necessary.

INTERIZING HE
Automotive antifreeze (ethylene glycol) and windshield washer antifreeze
(methanol) are poisonous. Never use these products in your fresh water
system. These products are harmful and may be fatal if swallowed
Preparing your RV for colder weather or storage is very important for most states
and Canada. Failure to prepare your RV may cause water supply lines and the
water heater to freeze.
No commodity or product should be added to the fresh water system to ensure
freeze protection other than RV antifreeze.
The RV should be winterized at the end of the camping season or when the RV
will be exposed to temperatures that will fall at or below 32°F (0°C). Repairs due to
freezing are not covered under the terms of the Towable Limited Warranty.
NOTE:
The water heater must be drained to prevent damage from
freezing. It is recommended the water heater be drained and bypassed during the
winterization process particularly if introducing RV antifreeze into the plumbing
system (Revision A).
There are two methods of winterizing your trailer based upon your model. Please
read, understand and follow all instructions before beginning.
Air pressure
This method will utilize an air hose to blow excess water from the water lines.
1. Make sure all holding tanks are empty and drain valves OPEN.
2. Run the water pump until it is dry, this will take approximately 15-20 seconds.
3. OPEN all faucets and drains, and the toilet.
4. Using an air hose and adapter (customer supplied), blow air through the city
water connection. Any remaining water will blow out in five to ten minutes.
5. Pour one cup of non-toxic RV antifreeze into all drain P-traps.
Demand or power plumbing system
It may be easier to winterize the RV with another person to assist you.
1. Level the RV and drain the fresh water plumbing system.
2. Replace the water filter cartridge with the clear plastic bypass hose (if so
equipped).
3. Make sure the water heater 12-volt and 120-volt interior control switches are
OFF.
4. Turn the water heater bypass valves to the BYPASS position.
5. Make sure the "fresh tank drain" and "low point drains" are closed.
