It's an almost 30 year old system and seems to be breaking down regularly. It was down again this past Sunday, when a number of boats came back from Rock Hall. Andy Gillis manages to get it back up and running, only to have it break down a short time later. The PSA porch conversation Sunday was about replacing the entire system. My questions: Does the entire system need to be replaced? Or are there 1 or 2 components -- i.e. the electrical system, the plumbing, the pump itself-- that are failing and need to be replaced. Or would it be more cost effective in the long run to start anew?
