capacity. This will result in a residual
chlorine concentration of 50 ppm in the
water system.
If a 100-ppm concentration is required as
discussed in step 9, use ½ cup of
household bleach with one gallon of water
to prepare the chlorine solution. One
gallon of the solution should be used for
each 15 gallons of tank capacity.
4. Pour the chlorine solution in at the gravity
fill connection.
5. Continue filling the fresh water tank with
potable water until it is full.
6. Turn the water pump ON.
7. After the recommended amount of
solution is in the tank, turn OFF the water
pump.
8. Open the hot water line on all the faucets
until water begins to flow continuously and
a chlorine smell is noticeable.
9. Close the hot water lines and repeat with
the cold water lines on the faucets.
10. Let the solution remain in the system for at
least four hours when disinfecting with 50-
PPM residual chlorine.
If a shorter time period is desired, then a
100-PPM chlorine concentration should be
permitted to sit in the system for at least
one hour.
11. After the required period, drain the
chlorine solution from the fresh water
system (see Draining the fresh water
system).
Some solution may remain in the water
heater and will be flushed in the following
steps:
11. Fill the fresh water system completely full
using clean (potable) water.
12. Then, drain the fresh water system (see
Draining the fresh water system).
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.
WINTERIZING THE PLUMBING SYSTEM
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.
There are two methods of winterizing your RV
depending upon your model. Please read,
understand and follow all instructions before
beginning.
Air pressure (all models)
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 (if so equipped) until
it is dry.
3. OPEN all faucets and drains, and the toilet
(if so equipped).
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.
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.
