Need Help Closing Pool
This is my first time trying to close my pool and I can't seem to blow out my lines. I hooked up my air compressor which flows 3.7 CFM at 40PSI and ran directly to the bottom drain for an hour without any bubbles! I checked everything 3 times and am sure all valves and coneections are correct. I used the filter drain plug to connect the air compressor which is about 100 feet from the bottom drain with 3" pipe. Is it possible my compressor just doesn't have enough CFM to work? Any help?
