Many recreational vehicle owners choose to have their units winterized by an RV service center, while
others choose to do it themselves. Following are descriptions of methods used to winterize:
• Compressed Air (Dry) Method — Uses compressed air to blow out any remaining water in the system
after draining the system of all water. This method requires an air compressor and appropriate adapters.
• RV Anti-Freeze (Wet) Method — Uses RV approved, nontoxic, potable, anti-freeze in the system and
does not require any special tools.
Following are procedures for both methods. If using the compressed air method, a special adapter (blow
plug) is necessary and should be purchased to allow compressed air to be delivered through the city
water fill. These adapters are available at most RV supply stores.
Method 1 - Compressed Air (Dry)
1. Purchase 1 gallon of RV non-toxic anti-freeze.
2. Drain the fresh water tank and empty the waste water holding tanks.
3. Turn water heater by-pass valve to by-pass position. (The by pass valve is located near the water
heater incoming lines.)
4. Drain water heater.
5. Open all faucets, including shower head sprayer, toilet flushing device and any other water lines that
are closed.
6. Turn on the water pump for 30 seconds to clear out any water in the lines.
7. Connect an air hose with an adapter (blow plug) to the city water fill connection.
8. Set the pressure no greater than 50 pounds and blow out the water lines until no water can be seen
coming out of the fixtures and lines.
9. Pour anti-freeze down shower, lavatory sink, and kitchen sink to fill p-traps.
Method 2 - RV Anti-Freeze (Wet)
1. Purchase 2-3 gallons of RV approved, non-toxic anti-freeze.
2. Drain all tanks, fresh water and sewage tanks.
3. Turn water heater by-pass valves to by-pass position. (The by pass valves are located near the water
heater incoming lines.)
4. Drain water heater.
5. Pour an amount of RV non-toxic anti-freeze into the fresh water tank to fill the tank above minimum
water pump operating level. (Use of a long funnel may be helpful) Add more, if necessary, during
procedure.
6. Turn on pump switch and open the cold water side of all faucet fixtures including shower head. Leave
open until the anti-freeze comes out (generally, pink in color). Repeat for hot water side.
