A garbage disposal can be either installed from scratch or instead of an older disposal.
First of all you need to shop for the disposal that best matches your needs.
For example you should consider whether a noisy disposal would be a problem in your household, what kind of plumbing you have, or if you have kids or not.
Here are some guidelines:
- Choose a motor suitable for your household. There are models with lower or higher horsepower, for smaller households with small amounts of food waste, or larger households with more food waste.
- Consider the features that you need. Like a quieter disposal, or one made of stainless steel, or one that connects to the dishwasher. There is a vast variety of options and prices.
- If you have kids you might want to consider getting a batch feed disposal rather than a continuous feed one. The batch feed disposal is a bit more expensive but it is also safer for kids, as it requires the use of a stopper prior operation. While the continuous feed disposal starts running when you flip the switch on and will continue running a bit also after you switch it off. This can be dangerous if someone drops utensils down the drain or sticks a hand inside the disposal.
- If your plumbing connects to a septic tank you need a disposal made for septic tanks.
After shopping for the right disposal, you need to get hold of these tools you'll be needing for the installation:
- Electrical cord
- Disposer wrench
- Water pump pliers
- Plumber's putty
- Safety supplies: goggles, dust mask, gloves
When you are ready, the first thing to do before installing the new disposal is to turn off power and make sure nobody turns it back on while you work.
Now you can proceed removing the old disposal.
If the old disposal is attached to a dishwasher, loosen and detach the dishwasher hose with a screwdriver.
Then with the wrench unscrew the slip-nut connecting the disposal to the "P" trap waste line, putting a bucket under the trap to catch any waste water sitting at the bottom of the trap.
Remove the old disposal with the screwdriver and take apart the rest of the mounting assembly, including the ring on the sink sleeve, the sink sleeve, the flange, the fiber gasket and the old plumber's putty. Make sure to clean well the sink, the sleeve, the flange and sink opening from old putty and grime before installing the new disposal.
You are now ready to wire your disposal, whether it came with appliance wires attached or if you need to attach them yourself following carefully the manufacturer's instructions (after unscrewing the cover plate beneath the disposal and then screwing it back in).
The next step is installing the drain flange and mounting ring by rolling some plumber's putty between your hands to form a snake about half inch thick and 10 inches long and applying it to the underside of the drain flange. Insert the flange into the drain hole and press down to attach it. You can then snap on the backup ring, fiber gasket and mounting ring.
Use a knife to cut away the extra plumber's putty that will have squeezed out around the flange.
At this point you can place the disposal into the mounting ring making sure that the disposal's outlet is facing the drain pipe connection, and tighten it until it stays in place.
Connect the P-trap, using the hacksaw to cut the discharge pipe to size if too long, and attach it to the outlet of the disposal. Make sure to connect it properly by reading carefully the manufacturer's instructions. If your disposal connects to the dishwasher attach the discharge tube to the disposal as well.
You can now turn the power back on and run cold water into the sink, turning on the disposal to make sure it's working and to check if there are any leaks, and running some food through the disposal to make sure it grinds and disposes properly.
Make sure to mantain your garbage disposal in good shape by avoiding grinding certain items like hard shells from shrimps, crabs or other shellfish, unpopped popcorn kernels and hard bones, by avoiding fibrous or starchy foods like banana peels, celery, potato peels, corn cobs, artichokes, fruit pits and hard seeds like avocados or peaches, onion skins and egg shells, as they create clogs and membranes that will ruin the disposal, and by cutting down big pieces of food into smaller pieces.
It is also best to run cold water while the disposal is on, keeping both water and disposer running for about a minute after the sink is cleared. Cold water helps push food down, avoid overheating of the system and unlike hot water, doesn't melt fat, that would re-solidify as a blockage further down the drain.
How about creating a compost barrel? Pretty easy, there is a site called family handyman that has a pretty straightforward plan for one. But, if you can't be bothered to do that, just google to quickly find a list of items that CAN'T go into a garbage disposal. Most garbage disposals that are installed correctly have a traditional 110/120v plugged into an outlet installed under the sink that you can easily disconnect. If it's wired directly into the house wiring, you'll need to determine which breaker in your service panel to turn off so that you don't get mildly electrocuted or chop off a hand or something. Most disposals have a small hex-shaped allen bolt hole underneath that you find an allen wrench to put in and work the disposal back and forth by hand, that should free up whatever clogs are inside. Make sure you leave some sort of screen or stopper in the drain to stop silverware or random things from falling in that shouldn't fall in like tea bags, ends of onions, tomato stems, nut shells, things that may not "shred" easily. If you need to ultimately replace it, (which is rare and unlikely), you will need to ask a neighbor or someone handy to figure it out, because not to sound like a chauvinist, but most women technically CAN do most things men can, they just don't WANT to, or can be bothered to learn or whatever else, that's why guys fix stuff and women typically don't. Anyway, good luck, I'm sure it's just a little clogged with some junk that your hands can reach in and take back out, I REALLY wouldn't worry about it being broken, I'm pretty sure it's not.
On the very bottom of the disposal there is a small opening in the very middle of the disposal. If you shine a light under the sink and put a mirror down on the inside of the cabinet you should be able to see this. You'll need an Allen wrench to put in the 6 sided hex hole and turn counter clockwise until the disposal turns freely. This should unjam your disposal. Don't forget you may have to hit the small reset button on the bottom too.
It is a small tool/ wrench that is hexagonal (six-sided) in shape, to be inserted in a screw head of the same style. The most common are just a six-sided steel rod bent in a "L" shape to create a handle.
can you turn it on for me? I would like to see and hear whats going on to better help diagnose, more than likely the "blade" that spins has detached from the disposal motor assembly or the "blade" my be caught/stuck in place, to resolve this issue. Unplug the disposal(should be plugged in under the sink)Grab a bucket to place under sink to catch waterremove the sink pipe assembly+disposal (remove the disposal)the water should drain into the bucket from the sink.remove and clean the disposal trap, looking for obstructions while you do so.after cleaning and searching for obstruction, reassemble the unit as it was making sure to reinstall all washers, guards and bolts, after you reassemble the unit plug it back in and test it, if you get the same results then there may be a strong possibility the unit suffers from a defect or damage in which case you may need to replace the whole unit or just part it all depends... good luck... more question just ask
