Model 46AS

15 year old macerator seized and tripped the circuit breaker. This item was physically very similar and was a perfect replacement. The old model 45 was actuated by a separate air switch whereas the replacement had an air switch built in. One puzzle, not having fitted one before, was the provided hexagonal section key for tightening the unit. Being hexagonal section it seemed as if it was an 'allen' key. It wasn't. It was simply a lever to insert into a lug in the upper attachment ring. The instructions didn't explain what the snap ring was for either. It's a ring that snaps in place after the part with the 3 screws is slid onto the sink waste outlet cylinder to give that screw item something to react against when you tighten the screws to make the waste seal. It's difficult relocating that snap ring with only two hands. I used some big blobs of 'blutack' to hold the screw ring up in place temporarily so I could use two hands to fit the snap ring below it. The unit's heavy so you need to support it underneath while fitting. In summary, a good buy and, once I'd overcome the fitting problems, straightforward to fit. Amazon doesn't like links in reviews. I've written all this up properly and I have a website howto.probably.me.uk and there's a suffix /macerator.

Purchase necessary because I've just moved. Delivered promptly. Competitive price. Works just fine. The air-pressure switch is an added refinement, removing any risk of electrocution due to operating a mains switch with wet hands. This Insinkerator will grind avocado stones in moments and cope with just about anything except corn on the cob husks and plum stones. It grinds to a puree consistency, too, so little risk of the pipes becoming blocked. I have never had a blocked waste pipe with any of the Insinkerators that I have used over many years. Nor have I known one to jam.

This was a very important purchase replacing our food disposal unit that had stopped working. The instructions were reasonably clear; all the parts were present; and the unit is working as planned. My greatest challenge was in finding the correct plastic piping for the various connections.

I have been looking at this food waste disposal for a while and finally took the plunge. We are a 4 person household, and cook everything from scratch. I have been using it for a few days and practically got rid of the food waste caddy. The biggest challenge was the plumbing configuration for the double sink.

Bought a cheaper waste disposal unit after moving back to the UK from abroad. Every sink in Australia and the USA have them. The UK not so many but once you have had one you will always need one. The cheaper unit only lasted 1 year and failed so I went to Insinkerator, the rolls royce of waste disposals, the quality and sturdiness is so much better than the cheaper brands. much easier to fit and the air switch is a must.

What I love about Insinkertor Waste Disposal units is their standardisation of fittings. This is our third one. The first one was much bigger and we used it for eight years until we moved in 2005 when we had to buy the slimmer one because the big one wouldn't fit our new kitchen. That original one still works and I gave it to a friend a few weeks ago. All he had to do was buy the sink flange and it works a treat, even now. The second, slimmer one, gave up the ghost last week and, within two days, I had the replacement in my hands, fresh from Amazon, and at a price very much in the same ball park as the original! That one was an air-operated version, as is the new one - well worth the money! Fitting it all took about two hours and I used a series of wooden blocks to prop it up as it slipped up into the new flange in the sink. I renewed the plastic drain pipes and did not replace the air-press button embedded in the worktop because it didn't need it. I just plugged the existing air pipe into the bottom of the unit. Well, we're back in business after just two miserable days of putting food in those little green council bags! A very big thank you to Insinkerator and of course, to Amazon, for rescuing us!

These work great - when they are working! But if you don't use them for a while, the internals rust and seize up. The puny wrench they say to use to un-seize is not really up to the job. I'm now on my second after 6 years as the first one was too badly rusted to repair. Why they don't make them with stainless steel internal I don't know.

This is the third waste disposal, of this type, I have installed. Like its predecessors, it will work fine for a few years before the blades rust and fall off. Then I'll replace it again. In the meantime, it will work OK but for leaking a little. You always need to keep a bowl under them, to catch the drips.
