How to Install a Garbage & Waste Disposal

What to do with leftovers? A garbage and waste disposal will make quick work of any of that uneaten food left on your plate, except for large bones, of course.

Planning and Picking the Right Model

Having enough room under the sink and the availability of electrical power are the most important things to consider when you want a garbage disposal. If you don’t feel comfortable working with electricity, then contact an electrician that also has experience with plumbing. Disposals should be on a dedicated circuit. The control switch should be close to the sink, but out of reach of young children.

Garbage & Waste Disposal

Precautions

Disposals are installed directly under the sink. Be sure there is enough room to allow for the P-trap in the drain line. Always, turn off the water supply and electrical power. Make sure that power and water cannot be accidently turned on while you are working under the sink.

Tools and Hardware

Proper kitchen lighting is always helpful especially when working under cabinets. Of course you will need split joint pliers, plumber’s wrench, screwdrivers, plumber’s putty, wire nuts and a hacksaw.

Installation

Remove the strainer from the sink by loosening the retaining nut. The flange of the disposal will replace the strainer. Clean the drain hole to ensure a proper seal. Roll the plumber’s putty into a snake and wrap it around the flange. Put the flange in the drain hole and set it securely. Install the gasket and upper- and lower-mounting rings on the flange.  Snap the retaining ring in place. Tighten the screws on the lower-mounting ring until the flange is firmly seated. Remove the excess putty. Attach the disposal to the flange. Read and follow the manufacturer’s instructions. Pop out the dishwasher plug if you want to attach the dishwasher drain. Attach the discharge tube to the discharge opening in the side of the unit and the dishwasher discharge to the designated nipple on the unit. Install the drain lines. If you have a two-bowl sink, both bowls can be routed through a single P-trap by running the discharge tube from the disposer to a T in the drain line above the trap. Last, connect the electrical wires to the appropriate circuit.  Read and follow the manufacturer’s instructions.

Waste Away

PlumbTile.com recommends reading and follow the manufacturer’s instructions about what foods can be placed in the disposal. Most disposal manufacturers recommend running cold water down the unit to keep grease from building up in the grinding chamber. And run the water for a few seconds after the unit is off to wash away any food particles. Enjoy your leftover free day! Shop at Plumbtile.com for all your disposal needs!
