Review on Camco Blow Out Plug with Quick Connect 💨 Brass Fitting - Facilitates Efficient Water Line Drainage (36143) by James Hounds

This is the right tool to blow air out of an RV's water lines. Follow the instructions to winterize your RV by using this adapter between your RV's municipal water intake and your air compressor. Be sure to reduce your air compressor pressure to 30 pounds so you don't damage your RV's plastic tubing. Once all the water has drained, continue to follow the winterization instructions in your camper manufacturer's owner's manual/instructions. Be aware that water may have gotten into your air pressure hose while using this tool. Be sure to blow out the air hose with a compressor before putting it away in frosty weather to avoid damaging the air hose. This item should be included as standard equipment on any RV that may need to be winterized rather than being purchased separately.
