I have a macerator that is installed in the crawl space next to the inside bathroom, about 4 feet below. It has a 3 inch inlet and a 2 inch outlet and services a toilet, shower and sink. Bathroom has worked fine for 2 years and now the pump is out and I have no information on the pump. Any ideas what pump I need? It is just like the other pumps, I.e., white box but it doesn't connect to the toilet. Help.
