end of the siphon tube into a pail or other
container with 2 to 5 gallons of non-toxic RV
antifreeze solution.

from the faucet, then close.
Do not forget exterior shower/wash station
knobs (if equipped).

siphon tube and revert the tank line flow to the
water pump.
11. Replace the protective cap onto the end of the
antifreeze siphon tube to keep out insects and
debris when not in use.
