Water Tank Drain Valve

WINTERIZING PROCEDURES

You can winterize the water and plumbing
system of your coach using one of the following
two methods – 1) Blow out waterlines using
compressed air or – 2) Fill waterlines with RV
water system antifreeze.
Method 1 – Blow Out Procedure
(Drain and purge waterlines using
compressed air)
1. Level the Motorhome. If the coach is not
level, there may be "low points" in waterlines
that can trap water in the lines and prevent it
from draining properly.
2. Drain Fresh Water Tank and Waterlines.
Open all waterline drain valves and drain
fresh water tank. (See "Water System Drain
Valve Locations" chart at end of this section
for locations of drain valves on your model).
3. Drain Exterior Shower/Wash Station.
Open exterior shower knobs, then point
shower hose toward ground and squeeze
handle to drain any water left in the shower
line. Also, place the tip of your finger into the
city water inlet and gently press the backflow
valve "button" in the center of the inlet to
drain any water trapped in the inlet line.
4. Remove the Cold Water Filter Cartridge (if
equipped). Remove the filter cartridge from
the filter assembly below the galley sink.
(If your coach is not equipped with a cold
water filter, continue to next numbered step.)
• Place a container beneath the filter to catch
any water that may drain from the waterline
during filter removal.
• Twist the filter cartridge counter-clockwise
(to the left) about one-quarter turn, then pull
it down and out of the filter socket. Discard
used filter.
• Install the diverter plug into the filter socket.
Insert plug up into the filter socket as far as
possible and twist clockwise (to the right)
one-quarter turn until it stops.
5. Open Faucets. Turn on the water pump and
open all sink faucets and shower head knobs.
Leave open after water stops flowing.
6. Drain Toilet. Press the toilet flush pedal and
hold until water stops flowing in the toilet.
Then turn water pump switch off.
7. Drain Water Heater (Tankless). Turn off the
Water Heater Power switch before draining
the water heater and let the water drain
through the system.
