This model of the InSinkErator Kitchen Waste Disposal Unit Model 46 includes an air switch. An air switch is for when you want to use something other than a wall switch. It simply mounts onto your kitchen sink and the installation process to do this couldn’t be easier.

What is a waste disposal unit for?

A kitchen waste disposal unit is a handy gadget that can easily fit underneath your kitchen sink. Its main purpose is to help you dispose of kitchen waste that can’t be recycled. This includes things like chicken bones and bread crusts, the likes of which must be put into your kitchen bin. This leads to more trips to empty the bin into your outside bin, which creates more waste that will end up in a landfill. Using a waste disposal unit will cut the amount of waste you produce, freeing up your bin and sending less to the landfill, which is all good from an environmental standpoint.

A waste disposal unit works by grinding down the waste you insert into fine particles. Once all the waste is dealt with, these particles will be disposed of down your kitchen drain. It’s convenient and hygienic solution to waste disposal.

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.

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!

    This is the third Insinkerator I have purchased since 1999, they do the job they are supposed to and are a handy addition to the kitchen. This was a replacement for one which had been in place for about 10 years and had developed a leak in the casing at the bottom - mechanically it was still working fine. I should have purchased the model without the air switch this time, as I hadn't realised the air switch we already have fitted from our previous one is a separate unit and not part of the Insinkerator itself, but it wasn't a problem as the air switch could be disabled on this new model and the old switch could still be used - but at least we now have the option of an alternative if our existing air switch ever breaks!

    This product was a compromise with my wife as I wanted a huge TV in the kitchen, I wasn’t overly excited about having one but went along with it. It installed really easily and now I don’t know how we lived without it. It will eat almost anything and eliminates having food waste in your bins stopping any nasty smells and bacteria. I would recommend anyone thinking of buying one to purchase it. Excellent product!

  • David Stone
    5/ 5

    Excellent product and a perfect fit under our sink. We like not filling our non-recyclable waste bin with food waste which ultimately becomes fertiliser. This is our third insinkerator in 21 years and only needed now because we’ve moved. Great quality and long life. Plumbworld were the only store with stock and the fourth or fifth time we’ve ordered since we moved and always excellent service and communication

    This unit is easy to install and is environmentally friendly in the disposal of domestic food waste. The air switch turns the unit on instantly and with added water the waste is easily disposed. This avoids the mess on taking the food waste to recycle bins which generate unpleasant smells and deterioration of waste leading to maggots especially in warm weather. This is an excellent buy!!

  • John

    I wanted a bigger version, but they would not fit under the sink without moving the dishwasher or the sink. Neither was an option so opted for this version. Fitted like a glove, measurements were exactly as spec. No problem following the instructions and works great, especially with the air starter that was not on the previous model.

    needed to replace a worn out model. Ordered this which was the replacement for the obsolete model. This one was a little more sophisticated as it had an air switch. I found it easy to install and it works a treat. I got great advice from plumbworld too about what model I needed. Thanks very satisfied customer!

    After visiting my sister in the US who has one of theses little beauties I’ve always wanted one. Just got my kitchen updated and the affordable prices from Plumbworld made my wish come true. My kitchen is now complete and no more smelly food waste in the bin for us. Thanks Plumbworld.

    5/ 5

    Had several of these over the years, they work well. First one with the push button which is easy to install either through a whole in the sink (some sinks come with a opposite side tap who cap that can be removed) or in the work surface if you want to drill a whole.

    Bought to replace model45 that gave up after about 8 years of use. Dimensionally a direct replacement so a quick 15 min job to remove the old one and fit the new leaving the existing sink coupling in place. Decent price, excellent delivery service

  • Phyllida Hepworth

    The new machine arrived in its box with no fuss and on time. The plumber/fitter was pleased with the make and model and it was soon fitted into the kitchen sink. I would highly recommend this product and now would not be without it.

    I've had insinkerators in all my kitchens and don't understand why everyone doesn't have one. There are no scraps and peelings to deal with and the bin doesn't smell. It was easy to install and is so quiet.

  • Sue Errington

    Took a bit of time to get it due to shortages, but I had regular updates so I was happy Plumbworld kept in touch with me. The WDU is in and working like a trooper. Happy with my purchase.

    This item arrived undamaged in good sound packaging - and very promptly. It has been fitted for me without a problem - it came with very clear instructions - and works extremely well.

    Perfect replacement for superseded model arrived on time as promised - useful tip to installers - use a car jack as it is v heavy to lift under sink while trying to rotate into collar

  • Dan

    Bought this as a replacement for my 12 year old model 45. Fitting was easy and it’s a lot quieter than the old model, I’m very happy with it and the price was very reasonable too.

    The updated model fits exactly the same, did not need to change any pipework. If this lasts 10 years like the one it replaced I will be very happy.

    very good for a basic model, I think it’s worth extra money for the air switch
