5 or.75 HP air compressor should do that job OK. If there’s convoluted piping, add higher pressure and get the flow of compressed air going into the pipe as fast as you can to build the volume of air inside the pipe quickly, to drive the water out before it. It will help a lot if the hot water tank has been drained first as that’s a lot of water and will take a long time for air from the compressor to blow all that water out. A small compressor that has a tank that holds 2-3 cubic feet of air, one with a regulator to reduce the outflow pressure if need, and an air hose with a high flow blow gun may be all you need for the small line that Phillip has a whole house water system will require a bigger air supply to ensure that compressed air drives all the water out before the air flowing into the water lines.
Whether it’s because you’re ready to winterize your RV or you simply want to flush your water pipes and start fresh, every RV owner should know how to blow out RV water lines properly. Blowing out your water lines while they still contain hot water can result in burns and other damage to the external components of your RV. That’s why we recommend turning off your water heater and allowing any water in your lines to cool for a day before you proceed. Most RV manufacturers recommend setting your air compressor between 30 and 40 PSI to blow out RV water lines.
Blowing out the pipes is how we winterized all the houses that we took. Turn the water pump breaker off, hook a garden hose to the drain fitting. To make sure that you have all the water out of the system.
