Air in fresh water lines on Pearson 424
I have a 3-tank fresh water system with 3 isolating valves and a foot pump.
Sometimes when running a facet, the electric water pump will start running and NOT re-pressurize the system due to air in the lines.
My question is: Where could the air be coming from. I have all 3 tanks nearly full. It sometimes happens at the dock, so no "heeling" is letting air in. It''s very inconsistent. I sometimes go weeks with no issues; then it''ll happen four or five times in a day.
Any ideas how I might resolve this problem?? Thanks.
