So am thinking I need a new Insinkerator as the old one is at least 10 years old, leaks and doesn't work just buzzes. So two questions please -
Which Insinkerator between models 46 and 56 (probably). 56 seems to have a better guarantee and stainless steel not galvanised - is the 56 worth it (assuming it fits instead of the smaller 46).
I saw it has some kind on Quicklock thing so that I supposedly just release the Quicklock, remove old unit and attach new. Should be do-able even by me, but most videos seem to show removing the whole thing the unit is attached to as well and installing the in sink drain as well with new putty etc. Is that bit necessary ? seems to negate the whole point of the Quicklock thing.
