No need to worry if your garbage disposal is on the fritz—installing a new one is a straightforward project that you can do yourself in just a few minutes. Start by switching off the power to the disposal at your home’s breaker box to ensure that you can work safely. Next, remove the old unit by detaching it from the mounting ring directly beneath the sink drain. Finally, install any necessary new mounting hardware, fit the new disposal into place, and turn on the water to test for leaks before giving it a trial run.
The premise behind the proper use of a disposer is to effectively regard food scraps as liquid (averaging 70% water, like human waste), and use existing infrastructure (underground sewers and wastewater treatment plants) for its management. Modern wastewater plants are effective at processing organic solids into fertilizer products (known as biosolids), with advanced facilities also capturing methane for energy production.
STEP 5 – If you are one of those rebellious types that never listens to wise instruction, then take off any rings and make sure that your hand is lubricated with liquid dish soap or cooking oil to reduce the risk of it getting stuck in the drain opening. Also, have a phone nearby. If your hand does get stuck, you can then call someone (using your other hand, presumably) to call a friend or 911 for rescue. If at all possible, don’t call a friend with a video camera phone, because they’ll probably embarass you by broadcasting your plight on YouTube.
Thanks so much! Clear, easy to follow instructions. We were able to follow step by step and got it done. I read somewhere that they used a car jack to hold the disposal when taking it off and putting it on. That was a really helpful tip for anyone else doing this. They’re fairly heavy. Also, it leaked when the gasket was just placed in the hole. We actually had to take it apart and put the gasket over the plastic pipe, then when you tighten the metal plate to connect it to the disposal, that sealed it. Anyway, thanks again. Being able to do this on our own saved us quite a bit of time and hassle.
Throw some ice down once in a while. While ice will not sharpen the shredders (as is commonly believed) it does knock off any debris buildup on the sharp edges that keeps them from grinding food properly. For better results, make special ice cubes from pure lemon juice or vinegar, or alternate with biodegradable cleanser (label them in your freezer!) Cover and seal ice trays used in your freezer for cleanser, and do not reuse trays for food or drink after having been used for cleanser. While using the disposal, be sure to run cold water at the same time.
Warranty - The average industry warranty on a garbage disposal is one year; however, it is not uncommon to see manufacturers’ warranties that can extend up to ten years. As a general rule of thumb, the more comprehensive and longer a warranty is, the more confidence the manufacturer has in the product they have made, but this is not always the case, so it is still important to do your homework.
Lay the disposal on its side under the sink so you can make the electrical connections. Make sure the circuit breaker is off. Remove the plate on the bottom of the disposal to expose the wiring and use wire connectors to connect the wires from the disposal to the matching wires from the power supply. Finally, secure the power cord to the bottom of the disposal using the proper connection. Replace the plate to cover the wires. (See Fig 6)
If your garbage disposal is not running, first check to see if it is plugged in and receiving power. If so then check to see whether it will turn freely with your service wrench. Most disposers are sent with a self service wrench. The wrench is silver and should be located on or near your garbage disposal. (Check under your sink!) If it will not turn freely using the wrench, the disposal is most likely jammed. Check to see if the reset button has popped out.
If the leak occurred under the sink and at the top of the disposal before you unplugged the sink drain, your leak is in the sink flange. This indicates that an improper seal exists between the unit and the sink, which can occur from corrosion or the disposal being bumped hard and out of place. This fix requires you to move the disposal altogether. Then apply a generous amount of plumber’s putty to the flange. Finally, replace the disposal and retighten the flange.
