square iconDrain and flush the gray and black holding tanks

If your RV doesn't have a built-in flushing system, clean the black tank out with a wand, or use a product like Flush King which allows you to clean both the black and gray tanks.

square iconDrain the water heater

Remove the drain plug and open the pressure relief valve. Caution: never drain the water heater when it is hot or under pressure.

square iconOpen all hot and cold faucets

Don't forget the toilet valve and outside shower as well. 

square iconLocate and open the low point drain lines

There will be one for the hot and cold water lines. Using the water pump will help force water out, but turn it off as the system is drained.

square iconRecap all drains and close all faucets

square iconBypass the water heater

If you do not have a bypass kit installed, the water heater will fill up with antifreeze before it goes through the water lines. This would waste close to six gallons of antifreeze.

square iconInstall water pump converter kit

OR disconnect the inlet side of the water pump (the line coming from the fresh water holding tank). Connect a piece of clear tubing to the inlet side of the pump and put the other end into a one gallon container of non-toxic RV antifreeze.

square iconTurn the water pump on and pressurize the system

Starting with the closest faucet, slowly open the hot and then cold valves until antifreeze appears. Replace the antifreeze container as required.

square iconRepeat this process on all faucets

Start with the closest and work your way to the farthest faucet. Don't forget the outside shower, if equipped.

square iconFlush the toilet until antifreeze appears

square iconTurn water pump off and open faucet to release pressure

Go outside to the city water inlet. Remove the small screen over the inlet and push in on the valve with a small screwdriver until you see antifreeze. Replace the screen.

square iconPour a cupful of antifreeze down each drain

Also, pour a couple of cups in the toilet and flush into the holding tanks. If your water heater has an electric heating element, make sure it is turned off. This will protect the element if the unit is plugged in while being stored.

square iconMake sure all faucets are closed

square iconConsult your owners manual

If your RV is equipped with an ice maker and/or washing machine, consult your manual to learn the process for winterizing those units.
