A regular garbage disposal system lasts concerning 12 years, so if it’s an attribute you want in your kitchen area, there is every chance that you’ll need to replace it eventually. Or, you may intend to install one for the very first time when remodeling an old kitchen.
If you are mounting one for the first time, realize that there are some electrical wiring and also plumbing skills needed– function you might intend to have a specialist do if you’re not completely certain of your abilities. For example, most existing building regulations require a specialized 20-amp 120-volt electrical outlet under the sink near the disposal. The outlet will need to be regulated by a switch that comes to an individual standing at the sink. There is a likelihood that this circuit is currently in your kitchen area, yet if it’s not, you’ll require to have this circuit set up prior to you can set up the disposal.
1. Get Rid Of the Old Disposal
The power should be separated from the old disposal prior to you remove it. This might be as straightforward as unplugging it from its electric outlet, but if the disposal is “hardwired” straight right into circuit circuitry, as holds true in some older installments you’ll require to first turned off the circuit at the major service panel. You do this by going to your electric service panel and changing off the breaker (or removing the fuse, if you have an old fuse panel) on the disposal’s circuit.
Eliminate the garbage disposal by disconnecting drain connections affixed to the disposal, after that separating the disposal from the flange assembly.
Remove the disposal flange setting up from the sink drain. Although it is in some cases feasible to make use of the very same flange setting up if you are replacing the old system with a brand-new one from the same supplier, it is usually best to change these components to make sure an excellent drain seal.
2. Mount the Drainpipe Installation as well as Mounting Ring
To mount the garbage disposal, you first require to set up the assembly that will hold it in place below the sink. This is a special type of drainpipe installation that contains a sink flange and also mounting ring that sandwiches around the top and also base of the sink drainpipe opening.
Seal the sink opening by placing a 1/2-inch-thick bead of plumber’s putty around the drainpipe opening from inside the sink. Place the brand-new disposal sink flange right into the sink opening as well as press it strongly into the plumbing professional’s putty.
Have someone hold the sink flange in position from the top as you function from under the sink. Take the coarse gasket as well as triangular add-on ring and move them onto the tailpiece of the sink flange.
Secure the ring by breaking the round clip spring or snap ring into the groove on the flange tailpiece.

3. Tighten the Placing Ring Assembly
Tighten down the placing setting up by tightening the 3 placing screws, tightening each a little bit at a time to gradually apply also stress. Tighten up the screws till the sink flange is limited versus the bottom of the sink as well as excess plumber’s putty has oozed out around the drain opening. Make sure not to overtighten; it’s possible to squeeze out all the plumbing professional’s putty that should be present to complete the seal.
Clean away the excess plumbing professional’s putty around the drainpipe opening inside the sink, making use of a rag.
4. Attach the Disposal’s Power Cable
Before installing the garbage disposal, you’ll need to connect its plug-in power cord. Eliminate the electrical cover plate found on the bottom of the disposal device. Install a stress relief installation in the red that the power cord will certainly go through, and also tighten up the fitting nut with pliers.
Feed the loose-wire end of the power cord with the pressure relief, and tighten the stress alleviation clamp onto the cord with a screwdriver. Making use of wire nuts, link the white lead from the disposal to the power cord’s white (neutral) cord, the black bring about the black (hot) cord cable, and also the green ground cause the cable’s environment-friendly ground cord. Tuck the linked wires into disposal electric box as well as re-install the cover plate.
6. Plan for a Dishwasher Link (optional).
In some installations, the dishwasher drain water is gone through the garbage disposal. If that is your situation, find the dishwashing machine inlet nipple area near the top of the disposal chamber. Place a screwdriver right into the nipple, and tap the screwdriver with a hammer (like a sculpt) to knock senseless the plug inside the nipple. The plug is a plastic disc that will fall under the disposal’s grinding chamber. Get to inside via the top of the disposal unit and also pull out the disc.
7. Link the Drainpipe Lines.
Attach the rubber discharge tube to the disposal system with its gasket and screws. Placement the disposal by turning it to make sure that the discharge tube aligns with the sink drainpipe waste catch. You may require to add expansion pieces or shorten the pipes to make the appropriate links.
Once the drain connection is made, link the dishwasher line, as appropriate. Move the dishwater pipe onto the disposal nipple area, as well as protect it with the clamp provided by the supplier.
8. Lock the Garbage Disposal Device in position.
Strongly secure the disposer to the sink installing setting up by tightening the revolving web cam collar on the disposal, using either a screwdriver for leverage or an unique wrench that might have featured the garbage disposal for this purpose. You likely will really feel a distinct “click” as the disposer locks into location.
9. Look for Leaks and Proper Operation.
Turn on the water as well as run it with the disposal to inspect all connections for leakages. If there are leakages, tighten up any loosened drainpipe connections. Plug in the disposal to the wall outlet and also make sure the circuit power is activated.
Check the operation of the garbage disposal by turning on the water and disposal and going down some food scraps right into the drainpipe.
