Macerator Pumps for Your Boat’s Holding Tanks

Live-aboard boats with large holding tanks also frequently use a macerator pump on their waste tanks. Similar to a fish box, your sewage tank is not something you want draining into your bilge.

There are a few things you need to avoid on your macerating pump. Although they are durable and meant to macerate small solids, they can break if abused.

These items can jam even a stainless steel macerating pump and cause it to fail prematurely. Read More
