WINTERIZING YOUR RV

Winterizing your RV can be a simple process, if you just follow the steps below. There are three ways to winterize your rig. We have listed them in order of our personal preference.

BEST METHOD:

  1. Drain fresh water tank.
  2. Drain hot water heater.
  3. Dump and flush both black and gray water holding tanks, leave gray water valve open.
  4. Screw compressed air adapter into fresh water inlet. The adapter is available from us or most RV dealers.
  5. Apply compressed air, keeping pressure less than 20 lbs/sq inch.
  6. Open each faucet, one valve at a time, allowing the compressed air to force the water out of the line. Don 19t forget the shower and toilet.
  7. Remove the drain plug from the hot water tank and allow the compressed air to blow out the remaining water. Leave drain plug out of hot water heater so if there is any water left in it the water will be able to evaporate. We leave the drain plug just inside the door so you will find it come springtime.
  8. Remove the compressed air source and adapter.
  9. Close the water heater by-pass valve. (SEE SPECIAL WATER HEATER NOTE BELOW)
  10. Remove the water line that runs between the fresh water pump and the fresh water tank, where it joins the fresh water tank. HINT: For a few dollars you can buy and install an adapter that will eliminate removing and reinstalling the fresh water line. It is a small three-way valve that goes on the fresh water line, between the fresh water tank and the pump. You can easily pump anti-freeze throughout the system by inserting the tube attached to the valve into a gallon of anti-freeze, turning the valve and starting the pump. Simply turn the valve back to its original position when you 19re done.
  11. Insert the end of the line into a gallon jug of RV anti-freeze. (NEVER-NEVER-NEVER USE AUTOMOTIVE ANTI-FREEZE!!!!!!!!!!!!!!)
  12. Start the fresh water pump. It will run for a few moments, sucking anti-freeze from the jug. It will stop as pressure in the system builds up.
  13. Open each valve of each faucet, one at a time, until the pink anti-freeze appears, shut the faucet. Don 19t forget the shower and toilet, also the outside shower if you have one.
  14. Remove the line from the jug of anti-freeze and reattach it to the fresh water tank.
  15. Pour a few cups of anti-freeze down each drain and the toilet.
  16. Using a hand pump attach the brass valve to the city water fill and pump anti-freeze into the city water outlet.
  17. Shut the gray water valve.
  18. You're done.

WATER HEATER NOTE: One of the most important accessories you can add to your RV is a water heater by-pass. It is a simple devise, one or two valves that isolates the tank from the rest of the water system. This is very important when you get ready to winterize. A water heater tank is normally about 7 gallons. Without the by-pass valve, you will have to fill that tank with seven gallons of RV anti-freeze before you can pump it throughout the rest of the system. With a by-pass valve, you can save 7 gallons of RV anti-freeze. Installation is a pretty simple do-it-yourself project, or any RV dealer can install it for you. You will save the cost of the valve in just a few years with the value of the anti-freeze you save.

BEST METHOD USING THE HAND PUMP:

  1. Drain fresh water tank.
  2. Drain hot water heater.
  3. Dump and flush both black and gray water holding tanks, leave gray water valve open.
  4. Screw compressed air adapter into fresh water inlet. The adapter is available from us or most RV dealers.
  5. Apply compressed air, keeping pressure less than 20 lbs/sq inch.
  6. Open each faucet, one valve at a time, allowing the compressed air to force the water out of the line. Don 19t forget the shower and toilet.

  8. Remove the compressed air source and adapter.
  9. Close the water heater by-pass valve. (SEE SPECIAL WATER HEATER NOTE BELOW)
  10. Attach the brass male coupling located at the end of clear tube to city water hand pump to the city water fill inlet.
  11. Insert the pump inlet hose into a gallon jug of RV anti-freeze. (NEVER-NEVER-NEVER USE AUTOMOTIVE ANTI-FREEZE!!!!!!!!!!!!!!)
  12. Open each valve of each faucet, one at a time, starting with the hot side of the faucet then the cold side until the pink anti-freeze appears, shut the faucet off. Don 19t forget the shower and toilet, also the outside shower if you have one. When doing the toilet have someone hold the flush pedal or hand levers open so the anti-freeze will come out the water line and into the toilet.
  13. Remove the line from the jug of anti-freeze disconnect the valve from the city water fill.
  14. Pour a few cups of anti-freeze down each drain and the toilet.
  15. Shut the gray water valve.
  16. You're done.
