Installing a garbage disposal is not a difficult task if you have an understanding of how plumbing and wiring work. With the right tools, you can easily do it yourself. The following is a comprehensive guide to installing a garbage disposal under your sink.
Things You’ll Neeed
1. An appropriate garbage disposal unit.
2. An outlet near the sink to power the disposal.
3. A screwdriver, wrench, and hacksaw.
4. Plumber’s putty and gloves.
The Step-by-Step Guide to Garbage Disposal Installation
1. Wiring the Unit
Some units come with the wires attached but others must be wired prior to installation. It’s important to find out which kind you have. If yours did not come with the wires attached, the first thing you’ll need to do is wire it.
Start by removing the cover and attaching wires of the same color together. Be sure to read the instruction manual that comes with your unit, as this will help you understand the specific wiring requirements of the particular brand you are working with. After you’ve completed the wiring process, replace the cover and tighten the screws.
2. Install the Mounting Ring
Take plumbers putty and roll it between your hands to form a thick, snake-like structure. Apply it to the underside of the flange. Insert the flange in the drain’s hole, and then attach the backup ring and fiber gasket. Finally, screw in the mounting ring.
When tightening the mounting ring’s screws, do not tighten each one simultaneously. Rather, continue switching to the next screw after each round of tightening. Alternating in this fashion will ensure that the ring fits evenly.
3. Attach the Disposal
Once the mounting ring is attached under the sink, you may fix the disposal to it. Place the disposal such that the garbage outlet is facing towards the drainpipe. After it’s properly positioned, tighten the rotating cam collar with a wrench or screwdriver so that the disposal becomes locked in place.
4. Connect it to the Drain Line
Attach the disposal outlet to the drain line. You may need to adjust the length of the pipe in accordance with your disposal. Use a hacksaw to cut down the measured length of the discharge pipe and fix it tightly to the drain line. Last but not least, plug in the power cord.
5. Check for Leaks
Run water through the sink and turn on the garbage disposal, then check for any leaks under the sink. If necessary, tighten the fittings. Finally, run some food scraps through to test whether the unit is functioning properly.
When to Call a Plumber
The above guide will help you mount your garbage disposal with ease, but doing it yourself is not always advisable. Consider hiring a professional plumber if any of the following applies to you:
1. You lack the appropriate tools.
2. You have no prior experience with plumbing projects.
3. The unit has leaks that you’re unable to fix.
4. You aren’t comfortable working under the sink.
Regardless of whether you install it yourself or hire a professional to do it, a garbage disposal will be a great addition to your kitchen.
