Section 8: Plumbing System
Each new recreational vehicle is winterized with RV antifreeze before it is shipped to the
dealer. To use the water purification system: full system canister water lines need to be
flushed of antifreeze and then the filter installed in the canister before use.
Refer to the manufacturer’s owner’s manual and the label on the water filter cartridge for
further information.

Do not allow water in the canister housing to freeze.
 Remove the filter before using anti-freeze to winterize the system or
chlorine solution to sanitize the system.

Flush canister housing thoroughly before it is put back into service
after winterizing or sanitizing.
 For best results replace filter every 6-12 months.

Do not use carbon cartridges where water is microbiologically un-
safe or of unknown quality.

Maximum operating pressure is 125 psi (8.75 bar).


Draining the Fresh Water System
Water tanks may be drained through a valve located near the tank. A recreational vehicle
with a demand pressure pump system will have low-point drains attached to the water lines
(normally located near the water tank).
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 & LP GAS
switches).
2. Open all faucets, including the outside shower faucet (if so equipped).
3. Open the “fresh tank drain” valve. All fresh water tanks can be
drained by one of two types of drain valves. A white plastic drain is
attached 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 handles
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 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.
