HOWTO: De-Winterizing
Water heater bypass valves
• • Open a hot water faucet and fill the water heater with water. Check for leaks at the two fittings at the top of the water
heater. These are plastic fittings - tighten them clockwise by hand if possible, or gently use a pair of pliers cushioned with a
cloth rag. DO NOT APPLY EXCESSIVE PRESSURE TO THESE FITTINGS. Do not overtighten past the point where they are
sealed from water leaks.
• • Drain the remaining contents of the fresh water tank to ground, and refill with fresh water. You can help get rid of any
residual chlorine smell by adding a half cup of vinegar to this tankful, letting it sit a few hours or overnight, and then
draining and refilling the tank.
• • You do not have to dump the water in your gray and black water tanks after dewinterizing immediately, since it's just water
and antifreeze.
