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. I 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 adaptor into the fresh water inlet. The adapter is available from Camping World or most RV dealers.
5. Apply compressed air, keeping the 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't 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. Reinstall drain plug.
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.
11. Insert the end of the line into a gallon jug of RV antifreeze. (NEVER-NEVER-NEVER USE AUTOMOTIVE ANTIFREEZE!!!!!!!).
12. Start the fresh water pump. It will run for a few moments, sucking antifreeze 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 red antifreeze appears, shut the faucet. Don't forget the shower and toilet.
14. Remove the line from the jug of antifreeze and reattach it to 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 in the fresh water line, between the fresh water tank and the pump. You can easily pump antifreeze throughout he system by inserting the tube attached to the valve into a gallon of antifreeze, turning the valve and starting the pump. Simply turn the valve back to its original position and you are done.

15. shut the gray water valve.
16. Pour a few cups of antifreeze down each drain and the toilet.
17. Your done.

SECOND BEST METHOD - Blowing Out the Lines

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 adaptor into the fresh water inlet. The adapter is available from Camping World or most RV dealers.
5. Apply compressed air, keeping the 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't 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. Reinstall drain plug.
8. Remove the compressed air source and adapter.
9. Pour a few cups of antifreeze down each drain and toilet.
10. Your done.

THIRD BEST METHOD - Fill the Lines with Antifreeze

1. Drain fresh water tank.
2. Drain hot water heater, turn by-pass valve. (SEE SPECIAL WATER HEATER NOTE BELOW)
3. Dump and flush both black and gray water holding tanks, leave gray water valve open.
4. Remove the water line that runs between the fresh water pump and the fresh water tank, where it joins the fresh water tank.
5. Insert the end of the line into a gallon jug of RV antifreeze. (NEVER-NEVER-NEVER USE AUTOMOTIVE ANTIFREEZE!!!!!!!).

9. shut the gray water valve.
10. Pour a few cups of antifreeze down each drain and the toilet.
11. Your 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 device, one or two valves that isolates the tank from the rest of the water system. This is very important when you get ready to winterizer. 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 antifreeze before you can pump it throughout the rest of the system. With a by-pass valve, you can save 7 gallons of RV antifreeze.

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 antifreeze you save.

Another Method:
How to Winterize an RV
Always use RV grade -50 Antifreeze.

• Locate water heater
• Pull out side drain or anode rod, release blow off valve to speed up water flow
• Locate water heater bypass on inside. Maybe 1 or 2 valves.
• Locate fresh water bypass
• Pull fresh water drains
• Pull low point drains and retighten
• Find and open all faucets interior and exterior and drain any water by cycling the pump on and off. This will also assist you in finding the pump location.
• Once Pump is located you may have to remove an access panel to get to the pump. Locate bypass to siphon tube or add you own siphon tube for the antifreeze. You want to run the antifreeze through the pump on the unit for 2 reasons, 1 to make sure the pump does not freeze and 2 the anti freeze helps to lubricate the pump.
• Drop siphon tube into the anti freeze and cycle pump. It should build pressure and the pump will cycle only when the pressure drops in the lines as your drawing the antifreeze through the faucets.
    * Open hot water 1st and be sure that the water heater bypass is working and no antifreeze is going into the water heater.
    * Open cold water and do the same to be sure the bypass is working on the fresh water tank as well.
    * Run enough water at each facet to be sure it is running pink and that the trap is full of antifreeze instead of water.
    * Do this to all faucets, interior then exterior and don’t forget about the shower faucet and hand hose or outside shower.
    * Flush toilet and after that you leave some antifreeze in the toilet to help the seal. Also don’t forget to cycle antifreeze through the rinse hose if toilet is equipped.
• Washer/Dryers and water hook ups for washers need to be done as well. Cycle the washer, hot and cold until you see pink and allow washer to drain in the spin cycle. Or with hookups run both hot and cold into a pail until pink.
• Ice makers need to be drained and blown out to remove water. Always leave detached.
    * Lift the shut-off arm on the ice maker until it locks into place in the off position.
    * Disconnect the water supply to the ice maker from the water solenoid. Leave the heater wire wrapped and connected to the solenoid valve connection.
    * Let the water drain out of the hoses from the water supply and the ice maker. Blow forced air from an air compressor through the hoses to rid the lines of all residual water drops.
• Water filters need to be drained and bypassed so be sure those do not get missed.
• Outside water hook ups need to have the screen pulled and the plunger pushed in to allow any excess water to flow out as well as the antifreeze to flow.
• Finally drain units black and then grey tanks.
• Disconnect battery and clean unit.
• It’s always a good practice to leave all faucets and drains cracked open as well as the black and grey tanks.
