A typical garbage disposal system lasts about 12 years, so if it’s an attribute you desire in your cooking area, there is every possibility that you’ll require to change it at some point. Or, you may intend to mount one for the very very first time when redesigning an old kitchen.
If you are mounting one for the very first time, realize that there are some circuitry as well as plumbing abilities necessary– work you may want to have a professional do if you’re not totally confident of your skills. For instance, the majority of existing building regulations need a devoted 20-amp 120-volt outlet under the sink near the disposal. The electrical outlet will need to be managed by a button that comes to a user standing at the sink. There is a likelihood that this circuit is already in your cooking area, yet if it’s not, you’ll need to have this circuit mounted before you can mount the disposal.
1. Remove the Old Disposal
The power should be detached from the old disposal before you remove it. This may be as straightforward as unplugging it from its electrical outlet, but if the disposal is “hardwired” directly right into circuit wiring, as is the case in some older installations you’ll require to initial shut off the circuit at the main service panel. You do this by going to your electric circuit box as well as changing off the breaker (or eliminating the fuse, if you have an old fuse panel) on the disposal’s circuit.
Remove the garbage disposal by disconnecting drainpipe links connected to the disposal, after that separating the disposal from the flange assembly.
Eliminate the disposal flange assembly from the sink drainpipe. Although it is in some cases feasible to utilize the exact same flange setting up if you are changing the old device with a brand-new one from the very same manufacturer, it is usually best to change these components to make sure a good drainpipe seal.
2. Set Up the Drainpipe Installation as well as Installing Ring
To set up the garbage disposal, you first require to set up the setting up that will certainly hold it in position below the sink. This is an unique kind of drainpipe installation that consists of a sink flange and mounting ring that sandwiches around the top and bottom of the sink drainpipe opening.
Seal the sink opening by putting a 1/2-inch-thick bead of plumbing technician’s putty around the drainpipe opening from inside the sink. Insert the brand-new disposal sink flange right into the sink opening and also press it firmly 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 fibrous gasket as well as triangular accessory ring and also slide them onto the tailpiece of the sink flange.
Safeguard the ring by breaking the round clip springtime or snap ring right into the groove on the flange tailpiece.

3. Tighten Up the Mounting Ring Setting Up
Tighten up down the mounting assembly by tightening the three mounting screws, tightening each a bit at a time to slowly use also stress. Tighten up the screws up until the sink flange is tight versus the bottom of the sink as well as excess plumber’s putty has actually oozed out around the drainpipe opening. Make sure not to overtighten; it’s possible to eject all the plumbing’s putty that have to exist to complete the seal.
Clean away the excess plumbing’s putty around the drain opening inside the sink, using a dustcloth.
4. Connect the Disposal’s Power Cable
Prior to placing the garbage disposal, you’ll require to attach its plug-in power cord. Get rid of the electrical cover plate located under of the disposal unit. Install a pressure relief fitting in the hole that the power cord will experience, and also tighten the suitable nut with pliers.
Feed the loose-wire end of the power cord with the strain alleviation, as well as tighten up the strain alleviation clamp onto the cable with a screwdriver. Utilizing cord nuts, connect the white lead from the disposal to the power cable’s white (neutral) wire, the black bring about the black (warm) cable cable, as well as the eco-friendly ground bring about the cable’s environment-friendly ground cable. Tuck the linked wires into disposal electric box and reinstall the cover plate.
6. Get ready for a Dish washer Link (optional).
In some setups, the dish washer 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. Insert a screwdriver into the nipple area, as well as tap 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 certainly come under the disposal’s grinding chamber. Get to inside through the top of the disposal system as well as pull out the disc.
7. Link the Drain Lines.
Attach the rubber discharge tube to the disposal system with its gasket and screws. Position the disposal by transforming it to ensure that the discharge tube aligns with the sink drain waste trap. You may require to add extension pieces or shorten the pipelines to make the correct connections.
When the drainpipe link is made, attach the dishwasher line, as applicable. Glide the dishwater tube onto the disposal nipple, and also safeguard it with the clamp provided by the supplier.
8. Lock the Garbage Disposal System in position.
Firmly secure the disposer to the sink mounting setting up by tightening up the turning webcam collar on the disposal, using either a screwdriver for utilize or an unique wrench that might have come with the garbage disposal for this objective. You likely will really feel an unique “click” as the disposer secures right into area.
9. Look for Leakages and Appropriate Procedure.
Turn on the water and also run it with the disposal to check all connections for leakages. If there are leaks, tighten any kind of loose drainpipe links. Plug in the disposal to the wall outlet as well as see to it the circuit power is turned on.
Evaluate the procedure of the garbage disposal by switching on the water as well as disposal as well as dropping some food scraps into the drainpipe.
