- Drain fresh water tank and hot water heater.
- Dump and flush both black and gray water holding tanks; leave gray water valve open.
- Screw compressed air adaptor into the fresh water inlet. Apply compressed air, keeping the pressure less than 20 lbs/sq inch.
- 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.
- Remove the drain plug from the hot water tank and allow the compressed air to blow out the remaining water. Reinstall drain plug.
- Remove the compressed air source and adapter.
- Close the water heater by-pass valve.
- Remove the water line that runs between the fresh water pump and the fresh water tank, where it joins the fresh water tank.
- Insert the end of the line into a gallon jug of RV antifreeze. (NEVER USE AUTOMOTIVE ANTIFREEZE!).
- 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.
- 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.
- Remove the line from the jug of antifreeze and reattach it to the fresh water tank.
- Shut the gray water valve.
- Pour a few cups of antifreeze down each drain and the toilet.
- You're done.
