Any remaining water must be removed from the water lines. There are two ways to remove the remaining water from
the lines:
•

Gravity Draining
Compressed Air
You must have an air compressor with an air hose
and an air nozzle.
1. Remove the water line from the outlet side of
the water pump (opposite side from filter).
2. Open the faucet that is furthest away from the
water pump.
3. Place the air nozzle against the end of the just
removed water line and blow air through
the system.
4. When water stops coming out of the Open fau-
cet, stop the air and Close the faucet.
5. One at a time, repeat this process on all faucets
and showers.
Gravity Draining

2. Remove the drain plug from the tee fitting on
the freshwater tank.
