Recently replaced our obsolete model with a 66.  Have personally had the smaller unit previously and constantly had problems with blockages because it wasn't munching things up properly.  The 66 has been great.  


I personally removed the quick lock brackets and seals and replaced them with the new ones that came in the kit.  It wasn't at all hard (if you are remotely DIY capable its pretty simple) and it was nice to have everything shiny and new, particularly the rubbers. 


Purchased mine from Mitre 10.  Bunnings had a good deal on them so I went to Mitre 10 and they honoured their best price promise and I got another 15% off.  Ended up saving well over $100 on the retail price. You could do the same with that NL deal.  


Just like a TV, bigger is always better 



So you took the thing in the sink out and replaced it with one that came with it. I guess you removed and replaced the putty ? Just wondering as I always seem to spend an inordinate amount of time with putty trying just the right amount and fiddling and scraping and adjusting and whatever.





Putty?  No putty.  Rubber seal under the silver ring that drops into the hole and then there are a couple of seals underneath that clamp up under the mounting bracket.  I have installed and uninstalled a few of these over the years and have only ever seen the seals used, no putty or silicon.      



That does sound infinitely preferable smile

My cheap crappy brand waste disposal died the other day.  Was 3/4 hp model and worked ok for more than 5 years.  The motor died.


I replaced it yesterday with an Insinkerator evolution 100 model.  I did glance at the 200 model, but apart from the >$1k price, the external diameter was a bit much - no room to fit it without shifting or cutting a clearance hole in an internal cupboard wall - which would have been a can of worms and required contortionist skills while using sharp tools.


Plumbing and an air-switch was already in place, so that part of fitting it was easy.  Getting the Insinkerator bayonet fitting in the sink was a bit of a PITA - you need to hold it and the flange etc that goes around it under the sink in place while you squeeze a spring wire circlip around the throat of the drain.  I didn't do myself any favours there - I like to use a bit of silicone grease on rubber seals - my fingers were a bit slippery.  Having a second person to hold the fitting down while you clip the thing in place would make things much easier,


The fitting from the unit to the waste pipe on that model is flexible rubber, good design as vibration from the unit is much less likely to cause issues / leaks in the waste plumbing. The old unit had a rubberised flange, I'd had to tighten compression fittings on the waste pipe / trap a few times when they leaked a bit.


There's a dishwasher waste fitting on the top of the unit, with instructions that state putting dishwasher waste in there "improves performance" (of what? it didn't say) but the dishwasher waste shouldn't be plumbed that way for the Australian market model (why not?  Some regulatory requirement?).  I assumed that the instruction included NZ, so fit the dishwasher waste at the normal place on the waste pipe fitting.


As far as performance goes, it seems to do what it's supposed to do.  I see no evidence so far that it works any better than the ~$200 model it replaced, it's supposed to have an "auto-reverse" set up which I guess means that if it did jam, it might unjam itself, I guess I'll find out.  It is pretty quiet - I can see a potential downside to this, if the nearby oven fans and rangehood are on, then it'd be hard to hear the waste disposal in operation - so you could turn it on or forget to turn it off without realising.


I've got the plug-in air switch box I used with the old unit (didn't have a built in air switch) and the new Insinkerator fascia mount switch.  I'll go and fit that at my FIL's place, I shudder when I see him with dripping wet hands on the switch for his waste disposal.

Put my 56 model in OK (so far, touch wood).


Was quite easy to take the old one out. Removing the old in-sink fitting was a bit of a fiddle from the point of view that it had been put in with a sealant so took a while to scrape that off. Putting new one in also pretty easy except for trying to offer this heavy lump up to the the new in-sink fitting in the correct orientation so all three of those tab things line up while also lining up with the drain (and also not letting it rest on / demolishing said drain).


Didn't bother with the air switch.


It has a bit of a vibration when running sometimes, which isn't helped I think by it not being central to the hole that was cut in the under sink shelf that's there, so it rubs on one side. Hopefully I'll enlarge that hole at some point (this year...)
