Kitchen waste disposal units are handy gadgets that can reduce the amount of waste that your kitchen produces on a weekly basis. InSinkErator have a sterling reputation for producing some of the best disposal units on the market today, and the Model 56 is no exception.

The Model 56 will break down unrecyclable kitchen waste – such as chicken bones and bread crusts – into tiny fine particles that are then quickly flushed away down your drain. The brilliant thing about this is that it means less kitchen waste going in your bin, which means less trips to empty it outside and less waste ending up in a landfill. So having a waste disposal unit is a great benefit both for you and the environment.

A huge benefit with the Model 56 is that it’s even quieter than other InSinkErator models, giving you all the benefits with less noise.


Made in the USA
1 Stage Grind

1 Stage Grind Process

This Insinkerator waste disposal unit features one stage of grinding. This process is where food is ground once before passing through drain pipes with water.

Air Switch

Built-in Air Switch

As the name suggests the air switch uses air pressure rather than electricity to activate the unit. This, in turn, reduces the risk of potentially getting an electric shock if your hands are wet.

Removable Baffle

Removable Easy to Clean Baffle

Quieter than your bog-standard waste disposal unit, the removable sound baffle is used to help reduce the amount of noise that your unit makes whilst in operation – ensuring minimal disruption in your kitchen. The baffle is also removable, making an easy job of cleaning.  This is the perfect model for those who love to entertain, no one wants a noisy disposal unit whilst you’re trying to tell your funniest stories!

980ml Capacity

980ml Grind Chamber Capacity

No need to worry about overfilling your unit as you’re covered by the Overload Protection features which ensure you can only place a suitable amount of food waste into the chamber. Saying that you have a large 980ml capacity within the grind chamber, which is more than enough!

    We had an Insinkerator 45 fitted by a plumber a few years ago. When it finally packed up I decided to upgrade to this unit and hoped it would be easy to fit myself with only modest DIY skills. Nothing could have been easier. Once the old unit was removed, I was able to pop the new one in in no time at all. I absolutely love the air switch. My wife used to be quite reluctant to use the old waste disposal, but with the air switch neatly fitted into the sink top, she loves it and uses it regularly. All in all, I am thoroughly delighted.

    Bought this monster following a decision from our council to reduce the frequency of our bin collections. Pleased to say it was an absolute dream to install, so easy! Using it is brill, our bin now only contains cellophane wrappers, so even when full doesn't weigh anything. 1 month on, bedded in nicely, quiet considering it isn't a 'quiet model', no smells, no issues, all is well. Plumbworld service and delivery was exceptional also, we will definitely consider them for future plumbing tasks!

    We have only recently installed this in last few days in our new kitchen. It was a bit tricky to instal with all the different wastes with a double sink and a insinkerator hot tap but my husband managed it after a few trips to B&Q. It’s extremely quiet when operating which is great as I expected it to be so much noisier. Only used once or twice yet so will be getting used to what we can put down it and what we can’t as there are certain things you must not put down it. Overall really pleased!

    Always wanted a waste disposal unit and when I finally had new kitchen then I had to have one..I bought his model as the cheaper ones have galvanised steel internals..this has stainless steel and is very powerful and surprisingly quiet.. Excellent bit of kit and easy to install..the only down side is the plug it should come with an extra plug with holes in so you don't accidentally drop small cutlery down it when emptying the sink..but maybe that's just me..buy one its the future..

    The instructions were easy to follow, although the unit is heavy, putting it on a pile of bricks to get it to the near height and then tapping in 3 wedges until it engages with the three tapered locking ramps helps taking the weight off ones arms and allow you to get the spanner provided into the loops to tighten the ring to seal the unit to the sink. This is second incinerator Ive bought the last one about 20 years ago, They are very reliable and of good quality.

    Bought this to replace previous model which went for 15 years and was thrown into the skip by the builders stripping out my old kitchen. Bought the equivalent model at an unbeatable price from Plumbworld. Although most of our food waste goes into the food waste bin this provides a good place to rinse off other bits before loading into the dishwasher. The build quality is fantastic and the motor is indestructible. Thoroughly recommended.

    September 8th at last I have a fully working waste disposal a replacement and what a pleasant surprise, so quiet and very good at disposal of waste I would recommend the '56' to all households for up to four people any higher model number more expensive as this one is more than adequate I'm very happy that I chose this make again. Thanks go to Plumbworld for the way they treat their customers and for the fast delivery.

    Bought this item to replace a failed unit, and very happy with the decision to buy a more powerful one. Much quieter to run, and the air valve attachment is ideal. Very easy to fit, with one small caveat - it is heavy to lift and hold in place in a small cupboard under the sink, but solved that problem by using a car jack! Service and delivery from Plumbworld were top notch, and at a great price too. Highly recommended!

    After many hols to the USA, finally got one of these, and it is brill, just like being back in the USA, the home of the Labour saving device. Been using it now for 2 months and it is one of those things, once you have had it a while you wonder how you did without one, this model seems to work fine for our family, we have 5 kids so quite a few left overs and food waste in general, would highly recommend this to anyone.

    Whilst remodelling our kitchen we were persuaded to have a look at a waste disposal unit for the simplicity and added hygiene of food disposal. The insinkerator 56 is a great addition and manages to munch almost everything (large bones excluded) we put in it. No more smelly bags of waste food! When we looked around for the cheapest supplier Plumbworld were the clear winner and the delivery was very fast.

    Telephoned for advice re best replacement model on Friday afternoon, ordered there and then following the advice, and product delivered next morning with no delivery charge. Cheapest price available was from Plumbworld. Despite having no plumbing skills, I fitted the replacement in less than an hour encountering no problems - just as the technical department said! Thoroughly recommend this company.

    Seen these on a recent trip to New Zealand where alot of houses have them. Thought it was a great idea so decided to look them up when back in the UK. Plumbworld was the cheapest I found online so decided to try one. Simple to order and product arrived quickly. Installation was quite easy and the performance has been great so far. No more messy kitchen bin bags from scraping plates etc. Recommend

    Direct replacement for a waste disposal from another manufacturer fitted to a Blanco Silgranit sink in just a few minutes, had to break-out one of the spare tap holes to fit the air switch button and all the existing plumbing lined-up perfectly. Early days yet but it's much quieter and more effective than the disposal it replaced. Happy so far and Plumbworld were by far the cheapest on the day.

    We have been using incinerators for many years. Some have been underpowered, although their sales blurb says they are wonderful. This machine is absolutely ace!, with the added benefit of the great Air Switch. The machine was ordered on the net, stated delivery time two days later, arrived on time well packaged correctly labeled. Great supplier. will ordering from them again!

    This is my third Insinkerator (change of house, not because of product failure... one was 20 years' old and another 30, and still going strong). My Insinkerators have been absolutely fault free and totally reliable, working efficiently. Inskinkerators must be the best performing, hassle free, electrical kitchen gadget that is used many times a day and goes on for ever.!

  • Fiona Simpson

    Named Homer by my children because it ate anything, the Sinkerator was a brilliant addition to the Simpson family kitchen. Finally after nearly 20 years service Homer expired and I naturally opted for a replacement Sinkerator. This one is quieter and works brilliantly. The family have named it Homer 2 because no one eats as much ‘junk food’ as Homer!

    I bought this to replace my Franke waste disposal which decided to chew up the food and deposit it in the kitchen cupboard below. This is so much quieter than my previous one, was easy to fit and clears the waste quickly. Would definitely recommend especially at the price.
