HOWTO: Water System Winterizing
Water heater fittings
• • To remove and drain the water heater, open the wardrobe to the left of the galley counter. Turn off and unplug the water
heater, and loosen the two water line fittings on the left side of the top of the water heater. These are plastic fittings-
unscrew them counterclockwise by hand if possible, or gently use a pair of pliers cushioned with a cloth rag. DO NOT APPLY
EXCESSIVE PRESSURE TO THESE FITTINGS. After you loosen the intake (blue) and outlet (red) lines, move them over to the
left side of the wardrobe wall and lift the entire water heater up. The large pipe on top is an overflow line which goes down
through a hole in the floor and is not fastened to the body - it will pull right out.
• • Take the water heater unit outside and invert it for approximately 30 minutes to drain. Shake and tilt it as necessary to
remove all water. Once it is drained, either plug the intake and outlet holes and store it in a secure location, or return it to
its position inside the wardrobe and reattach the water lines. Make sure it remains unplugged and turned off while drained
of water. Operating the water heater while drained will damage the unit.
• • Look for the drain underneath the driver's door for the fresh water tank drain. Open the valve and allow the tank to drain
until empty. Close the drain valve, open the driver's door, remove the orange plug in the fresh water tank gravity fill, and
pour in 2 1/2 of the three gallons of pink antifreeze, saving a half gallon for the drains. Replace the orange plug.
• • Turn the water pump on.
• • Open the galley sink faucet, both hot and cold sides, until you see undiluted pink antifreeze come out. Do the same with
the bathroom sink. Flush the toilet until you see pink antifreeze coming down into the bowl. Open both outside shower
faucets until you see undiluted antifreeze coming out of them.
