A common garbage disposal system lasts about 12 years, so if it’s an attribute you want in your kitchen area, there is every likelihood that you’ll require to replace it at some point. Or, you might intend to set up one for the very first time when remodeling an old cooking area.
If you are installing one for the very first time, be aware that there are some wiring and also plumbing skills needed– work you might intend to have a professional do if you’re not totally positive of your abilities. As an example, many present building codes call for a devoted 20-amp 120-volt outlet under the sink near the disposal. The electrical outlet will require to be controlled by a switch that is accessible to a user standing at the sink. There is a great chance that this circuit is already in your kitchen, yet if it’s not, you’ll need to have this circuit installed prior to you can mount the disposal.
1. Get Rid Of the Old Disposal
The power must be separated from the old disposal prior to you remove it. This may be as simple as disconnecting it from its electrical outlet, but if the disposal is “hardwired” straight into circuit electrical wiring, as is the case in some older installations you’ll require to initial shut off the circuit at the major circuit box. You do this by going to your electric circuit box as well as switching off the circuit breaker (or eliminating the fuse, if you have an old fuse panel) on the disposal’s circuit.
Eliminate the garbage disposal by detaching drainpipe connections connected to the disposal, then detaching the disposal from the flange setting up.
Remove the disposal flange setting up from the sink drainpipe. Although it is occasionally possible to make use of the same flange setting up if you are replacing the old unit with a brand-new one from the very same maker, it is generally best to change these components to guarantee a great drain seal.
2. Install the Drain Fitting as well as Mounting Ring
To mount the garbage disposal, you first require to set up the assembly that will certainly hold it in place below the sink. This is a special type of drainpipe installation that consists of a sink flange and also installing ring that sandwiches around the top as well as bottom of the sink drainpipe opening.
Seal the sink opening by putting a 1/2-inch-thick bead of plumbing professional’s putty around the drain opening from inside the sink. Place the brand-new disposal sink flange into the sink opening and also press it strongly right into the plumbing professional’s putty.
Have someone hold the sink flange in place from the top as you work from under the sink. Take the coarse gasket as well as triangular attachment ring as well as glide them onto the tailpiece of the sink flange.
Safeguard the ring by snapping the round clip springtime or break ring into the groove on the flange tailpiece.

3. Tighten Up the Installing Ring Assembly
Tighten up down the installing setting up by tightening up the 3 installing screws, tightening each a little bit at a time to progressively apply also stress. Tighten up the screws until the sink flange is limited versus all-time low of the sink and excess plumber’s putty has oozed out around the drain opening. Take care not to overtighten; it’s feasible to squeeze out all the plumber’s putty that must be present to complete the seal.
Clean away the excess plumbing professional’s putty around the drain opening inside the sink, utilizing a rag.
4. Link the Disposal’s Power Cable
Before installing the garbage disposal, you’ll need to attach its plug-in power cable. Get rid of the electric cover plate found on the bottom of the disposal device. Install a pressure relief installation in the red that the power cord will certainly experience, and also tighten up the suitable nut with pliers.
Feed the loose-wire end of the power cable with the strain relief, as well as tighten up the pressure relief clamp onto the cord with a screwdriver. Using wire nuts, attach the white lead from the disposal to the power cable’s white (neutral) cable, the black bring about the black (hot) cable wire, and also the green ground lead to the cord’s eco-friendly ground wire. Put the connected wires into disposal electrical box as well as reinstall the cover plate.
6. Get ready for a Dishwasher Link (optional).
In some installations, the dishwasher drain water is gone through the garbage disposal. If that is your situation, situate the dish washer inlet nipple near the top of the disposal chamber. Insert a screwdriver right into the nipple area, as well as touch the screwdriver with a hammer (like a sculpt) to knock out the plug inside the nipple area. The plug is a plastic disc that will fall into the disposal’s grinding chamber. Reach inside with the top of the disposal device and also pull out the disc.
7. Connect the Drainpipe Lines.
Attach the rubber discharge tube to the disposal device with its gasket and also screws. Placement the disposal by turning it to make sure that the discharge tube straightens with the sink drain waste trap. You may require to add extension pieces or reduce the pipelines to make the proper connections.
When the drainpipe connection is made, link the dishwashing machine line, as appropriate. Glide the dishwater hose pipe onto the disposal nipple area, and safeguard it with the clamp given by the supplier.
8. Lock the Garbage Disposal Device in Place.
Strongly lock the disposer to the sink mounting setting up by tightening up the turning web cam collar on the disposal, utilizing either a screwdriver for leverage or an unique wrench that may have come with the garbage disposal for this purpose. You likely will feel a distinct “click” as the disposer secures into location.
9. Look for Leaks and also Proper Procedure.
Turn on the water as well as run it through the disposal to check all links for leaks. If there are leaks, tighten any type of loosened drain connections. Plug in the disposal to the wall surface outlet and ensure the circuit power is turned on.
Evaluate the operation of the garbage disposal by switching on the water and also disposal as well as dropping some food scraps right into the drainpipe.
