WELL I GOT ONE.Hi Lyndon, a couple of members have bought macerators from Linda here. I do not know what make or model she sells but i am sure she will be along soon to tell you all about them
Olley is right I forgot that. Mine is the one with the prongs which fits straight onto the outlet and has plenty of power did'nt fancy the other type myself.Hi Lindon There seems to be two types, one has prongs which allow it to fit directly onto the 3" sewer outlet, the other needs a reducer. Personally and I have no proof of this, but I think the second one is more likely to get a blockage in the reducer pipe.
Some of the cheaper ones seem to lack power from what others have said.
