A normal garbage disposal unit lasts concerning 12 years, so if it’s a feature you want in your kitchen, there is every likelihood that you’ll need to change it eventually. Or, you might intend to install one for the really first time when redesigning an old kitchen area.
If you are mounting one for the first time, be aware that there are some electrical wiring and also plumbing abilities required– function you might want to have a specialist do if you’re not completely positive of your abilities. For instance, most existing building ordinance need a dedicated 20-amp 120-volt outlet under the sink near the disposal. The electrical outlet will certainly need to be managed by a button that is accessible to an individual standing at the sink. There is a great chance that this circuit is already in your kitchen, but if it’s not, you’ll require to have this circuit mounted prior to you can install the disposal.
1. Remove the Old Disposal
The power should be separated from the old disposal before you remove it. This may be as basic as unplugging it from its electrical outlet, yet if the disposal is “hardwired” directly right into circuit circuitry, as holds true in some older setups you’ll require to initial shut off the circuit at the main service panel. You do this by going to your electrical circuit box as well as switching off the circuit breaker (or getting rid of the fuse, if you have an old fuse panel) on the disposal’s circuit.
Eliminate the garbage disposal by separating drainpipe links affixed to the disposal, then separating the disposal from the flange assembly.
Remove the disposal flange assembly from the sink drainpipe. Although it is often possible to make use of the very same flange setting up if you are changing the old system with a new one from the same supplier, it is usually best to replace these parts to make sure an excellent drainpipe seal.
2. Set Up the Drainpipe Fitting and Placing Ring
To set up the garbage disposal, you first require to mount the setting up that will certainly hold it in position under the sink. This is a special type of drain fitting that contains a sink flange and also installing ring that sandwiches around the top and also base of the sink drainpipe opening.
Seal the sink opening by positioning a 1/2-inch-thick grain of plumber’s putty around the drain opening from inside the sink. Place the new disposal sink flange into the sink opening as well as press it strongly into the plumbing technician’s putty.
Have somebody hold the sink flange in place from the top as you work from under the sink. Take the fibrous gasket and triangular accessory ring and move them onto the tailpiece of the sink flange.
Safeguard the ring by snapping the round clip spring or break ring right into the groove on the flange tailpiece.

3. Tighten Up the Installing Ring Setting Up
Tighten down the installing setting up by tightening up the three mounting screws, tightening up each a little bit at a time to slowly use also pressure. Tighten the screws until the sink flange is limited against the bottom of the sink as well as excess plumber’s putty has oozed out around the drainpipe opening. Make sure not to overtighten; it’s possible to eject all the plumbing’s putty that should exist to finish the seal.
Clean away the excess plumbing’s putty around the drainpipe opening inside the sink, making use of a dustcloth.
4. Attach the Disposal’s Power Cable
Before installing the garbage disposal, you’ll need to affix its plug-in power cable. Get rid of the electric cover plate discovered on the bottom of the disposal unit. Mount a strain alleviation fitting in the red that the power cord will certainly undergo, and also tighten up the suitable nut with pliers.
Feed the loose-wire end of the power cord through the pressure relief, and tighten the strain relief clamp onto the cable with a screwdriver. Making use of cable nuts, attach the white lead from the disposal to the power cord’s white (neutral) cord, the black cause the black (hot) cord cable, and also the eco-friendly ground lead to the cable’s green ground wire. Tuck the linked cables right into disposal electric box and reinstall the cover plate.
6. Prepare for a Dishwashing machine Link (optional).
In some installments, the dishwashing machine drain water is run through the garbage disposal. If that is your case, locate the dishwasher inlet nipple area near the top of the disposal chamber. Place a screwdriver into the nipple, as well as tap the screwdriver with a hammer (like a carve) to knock senseless the plug inside the nipple area. The plug is a plastic disc that will come under the disposal’s grinding chamber. Get to inside through the top of the disposal unit and take out the disc.
7. Connect the Drain Lines.
Secure the rubber discharge tube to the disposal system with its gasket as well as screws. Placement the disposal by transforming it to make sure that the discharge tube straightens with the sink drain waste catch. You may require to include expansion pieces or reduce the pipes to make the appropriate links.
As soon as the drainpipe link is made, link the dishwasher line, as appropriate. Move the dishwater hose onto the disposal nipple, as well as secure it with the clamp supplied by the manufacturer.
8. Lock the Garbage Disposal Unit in position.
Strongly secure the disposer to the sink mounting setting up by tightening up the rotating web cam collar on the disposal, using either a screwdriver for utilize or a special wrench that may have come with the garbage disposal for this objective. You likely will really feel an unique “click” as the disposer secures into area.
9. Look for Leakages as well as Proper Procedure.
Activate the water and also run it with the disposal to examine all connections for leakages. If there are leaks, tighten any kind of loosened drainpipe links. Plug in the disposal to the wall surface electrical outlet as well as ensure the circuit power is switched on.
