SECTION 7
PLUMBING SYSTEMS
To Fill Lines with RV Water Line Antifreeze
· Turn water heater by-pass valve to BY-PASS
position.
· Remove and save the protective cap from the
end of the siphon tube.
· Insert the end of the tube into a container of
RV antifreeze solution.
· Turn the diverter valve handle to divert posi-
tion.
· Turn a water pump switch on.
· Open each cold water faucet handle in the
coach one at a time until antifreeze solution
just begins to flow from the faucet, then
close.
When Done Adding RV Antifreeze:
· Turn water pump switch off.
· Turn the diverter valve handle so it points
toward the water line to the pump as shown in
the photo. This will stop the flow from the
siphon tube and revert the tank line flow to
the pump.
· Replace the protective cap onto the end of the
siphon tube to keep out insects and debris
when not in use.

ing illustration.
