Re: Macerator system
The advantages are 1) no 3" 'slinky' hose, it uses a 1" or 3/4" 'garden' style hose. 2) it can pump the sewage a long distance or even uphill. The disadvantages are that it requires either water or power, and tends to be slower than a standard dump. So no, it is not necessary, but sure comes in handy sometimes.
