Comments about Macerator Pump:
We installed the Johnson macerator a few years ago, it never worked well and wouldn't prime itself if level was even an inch lower than the pump. When I finally decided to change it in preparation for a trip, the only pump I could get locally was the same one, and it failed after one use. Don't waste you rmoney, buy the Jabsco
