A normal garbage disposal unit lasts regarding 12 years, so if it’s a function you want in your cooking area, there is every likelihood that you’ll need to change it eventually. Or, you might intend to install one for the extremely first time when redesigning an old cooking area.
If you are mounting one for the first time, understand that there are some wiring and also plumbing abilities essential– function you may want to have a professional do if you’re not completely confident of your skills. As an example, the majority of existing building ordinance call for a devoted 20-amp 120-volt electrical outlet under the sink near the disposal. The electrical outlet will need to be regulated by a switch that is accessible to an individual standing at the sink. There is a good chance that this circuit is already in your kitchen, yet if it’s not, you’ll require to have this circuit mounted before you can mount the disposal.
1. Remove the Old Disposal
The power needs to be disconnected from the old disposal prior to you remove it. This might be as straightforward as unplugging it from its electrical outlet, however if the disposal is “hardwired” directly into circuit wiring, as holds true in some older installations you’ll need to initial shut off the circuit at the primary service panel. You do this by going to your electrical circuit box and also switching off the breaker (or eliminating the fuse, if you have an old fuse panel) on the disposal’s circuit.
Eliminate the garbage disposal by separating drain links connected to the disposal, after that disconnecting the disposal from the flange setting up.
Eliminate the disposal flange setting up from the sink drain. Although it is occasionally feasible to utilize the very same flange assembly if you are changing the old system with a brand-new one from the exact same producer, it is generally best to change these parts to make sure a good drain seal.
2. Mount the Drainpipe Installation as well as Installing Ring
To set up the garbage disposal, you first need to mount the assembly that will certainly hold it in place beneath the sink. This is an unique form of drain fitting that consists of a sink flange as well as installing ring that sandwiches around the top as well as base of the sink drain opening.
Seal the sink opening by positioning a 1/2-inch-thick grain of plumbing professional’s putty around the drain opening from inside the sink. Insert the new disposal sink flange right into the sink opening and press it firmly right into the plumber’s putty.
Have a person hold the sink flange in place from the top as you function from under the sink. Take the fibrous gasket as well as triangular add-on ring and slide them onto the tailpiece of the sink flange.
Safeguard the ring by breaking the round clip springtime or snap ring into the groove on the flange tailpiece.

3. Tighten the Installing Ring Assembly
Tighten down the mounting setting up by tightening the three mounting screws, tightening each a little bit each time to gradually apply even stress. Tighten the screws till the sink flange is limited against the bottom of the sink and excess plumber’s putty has actually oozed out around the drain opening. Make sure not to overtighten; it’s feasible to eject all the plumbing’s putty that should be present to complete the seal.
Clean away the excess plumber’s putty around the drain opening inside the sink, making use of a dustcloth.
4. Link the Disposal’s Power Cable
Before placing the garbage disposal, you’ll need to affix its plug-in power cable. Get rid of the electrical cover plate discovered on the bottom of the disposal device. Mount a strain relief installation in the hole that the power cable will undergo, as well as tighten the fitting nut with pliers.
Feed the loose-wire end of the power cord through the stress alleviation, and also tighten up the strain alleviation clamp onto the cable with a screwdriver. Making use of cable nuts, attach the white lead from the disposal to the power cable’s white (neutral) wire, the black result in the black (hot) cord wire, and also the green ground bring about the cable’s green ground wire. Put the connected cords right into disposal electrical box as well as re-install the cover plate.
6. Prepare for a Dish washer Link (optional).
In some setups, the dish washer drain water is run through the garbage disposal. If that is your situation, find the dishwashing machine inlet nipple near the top of the disposal chamber. Place a screwdriver right into the nipple, and also 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 come under the disposal’s grinding chamber. Get to inside with the top of the disposal unit and also pull out the disc.
7. Link the Drain Lines.
Attach the rubber discharge tube to the disposal unit with its gasket and also screws. Placement the disposal by turning it to make sure that the discharge tube lines up with the sink drain waste trap. You might need to include expansion items or shorten the pipes to make the correct connections.
As soon as the drain link is made, attach the dishwasher line, as suitable. Move the dishwater tube onto the disposal nipple area, and safeguard it with the clamp supplied by the maker.
8. Lock the Garbage Disposal Unit in position.
Firmly lock the disposer to the sink placing assembly by tightening the turning cam collar on the disposal, using either a screwdriver for leverage or an unique wrench that might have included the garbage disposal for this purpose. You likely will feel a distinct “click” as the disposer secures right into location.
9. Look for Leakages as well as Appropriate Procedure.
Switch on the water as well as run it through the disposal to inspect all connections for leaks. If there are leaks, tighten up any kind of loose drainpipe connections. Plug in the disposal to the wall surface electrical outlet and make certain the circuit power is turned on.
Check the procedure of the garbage disposal by activating the water as well as disposal as well as dropping some food scraps right into the drain.
