I made my own air connection for my previous coach (2004 Damon Intruder). I too will be winterizing my new (to me) 2006 Fleetwood Pace Arrow but there are two items I did not have on the Damon. They are an ice maker and a washer/dryer combo. I am a bit nervous about doing it right. I called Fleetwood and they sent me some great documentation. One item has an excerpt for blowing out the water lines using an air compressor. I plan on using antifreeze, but first I will blow out the lines as I always did with my previous coach.
Here's that excerpt:
Method 1: Compressed Air
Purge the water system with compressed air instead of using antifreeze.
1) Purchase a compressed air adapter from your RV dealer or service center. Attach the compressed air adapter onto the main fresh water inlet.
NOTE: Regular air compressors and air hoses at service stations run at pressures often in excess of 100 PSI. Air pressure MUST be less than 20 PSI. Consult your compressor ownerโs manual for details on how to adjust pressure.
2) Turn on the compressor. Starting at the point furthest from the compressed air source, open each valve or faucet (both hot and cold) one at a time to purge water from the lines.
3) When all water has been expelled from the system, shut off the compressor and close all faucets and valves after air pressure has bled off the entire system.
