Most macerators will have to be maintained regularly (especially if the occupants still think they are in the S&B
like my wife !)
The impellers will get clogged up with 'stuff' and need to be cleaned...
So, I've actually gone away from our built in macerator for that and a couple of reasons...
IMHO, it's no more convenient than the slinky stinky,
takes up a lot of room in our wet bay,
it's slower evacuating the tanks (meaning does it really clean out completely at that slow a rate)
IF you MUST go uphill though, it is your only choice, and going uphill defeats the positive feature of allowing the bypass of liquids when tank valves are closed...
soooo, I like the WHOOSH from the 3 inch outlet more than the sanicon.
good luck in your decision..
