A sink garbage disposal unit is a motorised appliance that is installed directly beneath your kitchen sink. Its main function is to shred solid food waste into smaller pieces so it can be safely flushed down the drain without causing blockages. Breaking your waste in this way, it makes kitchen clean-up simpler while also helping to reduce the volume of food waste that is sent to landfills, leading to fewer harmful greenhouse gases.
Contrary to popular belief, garbage disposals don’t have blades. They work by rotating head discs that use centrifugal force to push food onto a grinding plate, which then shreds the food into small pieces that pass through your pipes.

Here at Purity Plumbing, we know that one size doesn’t always fit all. No matter what type of kitchen you have, we will help you find the best food waste disposal unit for your home and lifestyle. There are two main types of sink garbage disposal systems:
This is the most popular model and you will find it in most modern kitchens. It runs as soon as you flick the switch on the wall and stays on until you turn it off. These units are great for busy small kitchens, allowing for quick cleanup after meals. If you are looking to improve your kitchen waste management and overall kitchen experience, a continuous feed waste disposal unit is right for you.
Batch feed units work similarly to the continuous feed model but have an added layer of protection. Unlike standard units that work via a wall switch, these are activated only when a specialised magnetic drain cover is locked into place. The motor can’t start until the chamber is empty, ensuring that no stray fingers, jewellery or cutlery can enter the unit.
This model is ideal for kitchens that have small children or for an island kitchen sink where installing a wall switch is impractical.
As sink garbage disposal units have both plumbing and electrical components, attempting DIY is not a good idea. A loose connection can lead to water damage underneath your cabinets or can even lead to electrical shocks. Letting our qualified and experienced electricians handle the job, you ensure a watertight seal and a whisper-quiet unit.
Our technicians don’t just plug it in and hope for the best - we calibrate your unit to your existing plumbing systems and make sure your kitchen remains an efficient and safe space for you to enjoy.

Many homeowners see their sink disposal unit as an extension of their rubbish bin. This isn't entirely true. If you treat your disposal like a bin, throwing all sorts of food waste in it, you can run into a range of problems later down the track, like clogged drains or a burnt-out, overworked motor.
To keep your disposal unit running smoothly, it’s important to know what you can and can’t put down the sink:
When disposing of food waste in your in-sink disposal unit, always make sure to use plenty of cold water to help break up and flush the waste away.
To get the most out of your disposal unit, make sure to feed food into it in small batches. This helps to not overload the motor, improving its lifespan.
While your disposal unit can break down all sorts of kitchen waste, there are things your kitchen sink and plumbing just can’t deal with. Avoid putting these foods down your sink:
Continuing to put these items down the drain will lead to blocked drains and smelly sinks.
