How To: Install a Sink Disposal

Depending on what part of the world you’re from you may have heard sink disposals described as “waste disposal unit,” “food waste disposers,” or, if you’re truly appropriate, a “sink waste disposal device.” Whatever you call it, switching one out or setting up a brand-new one is a relatively easy job.

GETTING GOING

There are essentially 4 connection points for a sink disposal:
– Where the disposal links to the sink, under the drain
– Where the drain line links to the disposal to eliminate water/waste
– Where the disposal connects to power
– Optionally, where the dishwasher links to the disposal

The most vital things to understand are how the disposal gets power (either through a plug or direct connection) and whether you require a dishwasher line connected to the disposal.

What You’ll Need
– Disposal device
– Possible outlet connection kit if the disposal has to be plugged into an outlet
– Screwdriver(s)– Flat and Phillips
– Hammer
– Plumber’s putty/putty knife
– One “self-service wrenchette” (Included with disposal, and no, I’m not making this up.).

SETUP.

Step 1: Wiring for power.

To prep your unit for setup, you might have to connect a cord with a plug to reach the outlet, or extension wires to reach a hardwired box. In this case, I attached a cord with a plug kit that I purchased individually from the disposal system. It’s as easy as feeding the wires from the cord through the disposal and attaching them to the matching colors on the system with wire nuts.
If you need to hardwire the device, wait until it’s installed under the sink. Note: It’s most likely a good idea to shut down power at the breaker now, so about avoid forgetting to shut it off later on. If there’s anything worse than being surprised by a live wire, it’s being shocked by a live wire while under a sink.

If there’s an existing disposal, make use of the helpful self-service wrenchette to disengage the old unit from the bottom of the sink. It will fit in the holes on bottom piece of the bracket. Twist the bottom piece clockwise while supporting all-time low to obtain it free.

Step 2: Dishwasher Punch Out Option.
This is not something you finish with a misbehaving machine, but it’s an extremely vital step if you have a dishwasher and you desire it to work. If you do not have a dishwasher you can skip directly to

Step 3. For everybody else, there’s a little plug inside the dishwasher connection which has to be punched out with a screwdriver and hammer. Again, only do this if you are attaching a line from a dishwasher at the time of installation.

Step 3: Installing the Drain.
If there was an existing disposal connected to the sink already, it’s likely that the brand-new unit will certainly fit the existing bracket. If not– or if there is no disposal currently in place– start by eliminating the old drain. Most drains are connected to the sink by a huge nut beneath the sink that can be turned counter-clockwise to loosen.

Setting up the brand-new drain is a basic matter: First, develop a snake out of plumber’s putty and circle the drain from the top, like this:.

Then install the leading half of the drain from the top, and screw the nut and installing bracket on from underneath. Make certain to get rid of any excess plumber’s putty utilizing a putty knife.

Step 4: Installing New Unit.
Position the device so the existing pipes/hoses line up, and then choose your self-service wrenchette to move the bottom piece of the mounting bracket counter-clockwise up until tight.

Then attach the waste pipeline (and dishwasher hose, if appropriate). If your device is outlet-ready– focus on this part– make sure your disposal switch is in the “off” position before you plug the brand-new system in. While it’s not likely that having a disposal start up while your head is pressed versus it will cause decapitation, it may scare a number of years off your life. Not that I would understand from experience.

If you have to hardwire the device, make sure the power is off to the box (I advise shutting it off at the breaker) then attach the wires to the matching color using wire nuts.
