HOW TO INSTALL A GARBAGE DISPOSAL UNIT – It really isn’t that difficult to install a garbage disposal unit in your home. Most manufacturers offer models with efficient grinding capacity and quieter operation along with detailed installation instructions. So let’s get started…
SAFETY FIRST - Turn off your power supply. Make sure that it is off by plugging in a kitchen appliance, such as a kettle, and turning it on. If the kettle does not work then you know you have successfully turned off the power.
As an extra safety precaution, get yourself a Post It Note, or other piece of paper, and write a note telling others in your household that you are working with electrics, and stick this on the front of the mains fuse box.
After you have selected and purchased your new garbage disposal unit read through the manufacturer’s instructions for installation and operational guidelines carefully and thoroughly.
If you already have a garbage disposal unit installed then remove this by unplugging it and turning off the water supply. It is an excellent idea if you take a photo of your existing garbage disposal unit prior to removal. This will give you a visual reference when installing your new one.
Place a bowl under the unit to catch any waste water and debris from your old unit. Identify the discharge tube that leads off of the disposer and disconnect it.
Quick Tip: If you have a Dishwasher that is connected to your existing garbage disposal unit then drain the Dishwasher first before disconnecting the waste pipes.
Locate the mounting collar that holds the top of the garbage disposer to the bottom of the sink – this will look like a large plastic nut. Unscrew and remove the mounting collar with a garbage disposal wrench – check the packaging of your new unit these are generally included with the unit.
Sometimes, but not always, the garbage disposal unit may be ‘Hard-Wired’. If this is the case then lay then located the electrical cover plate and remove it and then disconnect the wires. If you are installing a unit that is also ‘Hard-Wired’ then mark the wires as you remove them with some electrical tape so that you have an easy reference guide to wire in your new garbage disposal unit.
With the old garbage disposal unit fully disconnected you can now install your new one by simply working in reverse. REMEMBER – Follow the manufacturer’s installation instructions fully and carefully.
