Having had pressure water and similar plumbing in previous boats, SOP was to fill the tanks, activate the pump breaker and open the faucets until the water runs clear. The odd thing about this is that you can leave the faucets run and the bubbling never stops. In the previous boats, the air purges out of the lines in pretty short order. Second odd thing is that the pump will continue to run with the faucets off like it is maybe trying to presurize the air in the lines?

This is the first system that did not work as delivered from the factory, so is also my first experience with trying to troubleshoot. This boat has just been full of first experiences.
