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.

    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!

    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 one its the future..

    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

    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.!

    This was a replacement for a previous model which had started to leak water from the motor housing when activated. Plumbworld not only had the lowest price but also delivered very quickly. very pleased with the performance of the new model and also the excellent service. Thanks Plumbworld

    Can't comment on the product yet as it's still in its box! However I can review the purchase process....... The purchase was trouble free, customer service was excellent, delivery was also trouble free. All in all exemplary and I would highly recommend Plumbworld.

    The installation manual states that this model comes with both chrome and satin finishes for the air switch.You can choose which one suits your kitchen. Mine came with only the chrome finish. Plumbworld were not helpful. But Insinkerator sorted it out.
