Garbage Disposal With High Drain Outlet

Garbage Disposal Replacement And Installation

Garbage disposals last approximately 12 to 15 years if they are maintained. If your unit jams up frequently or makes loud noises, it may be time to replace it.

Every installation or replacement we handle is different because plumbing systems and electrical services vary from kitchen to kitchen. If this is your first garbage disposal, we can confirm if your plumbing is ready to handle a new appliance.

We can help you choose the best garbage disposal for your needs and budget. If you have a big family and frequently prepare meals at home, you may need a unit with more horsepower. Typically, more powerful garbage disposals are bigger than standard models. The space available under your sink may dictate the brand or model you choose.

• Do you want stainless steel or galvanized steel components in your new garbage disposal?
• Do you prefer a hard-wired model or one that plugs into an electrical outlet?
• Is continuous feed or batch feed better for your needs?

A continuous feed garbage disposal enables you to add scraps as it operates. Batch feed models only run when a safety stopper covers the drain.

Our experts can advise you about the many features available, including noise reduction technology, single- and multiple-stage grinding, push-button starters, and dishwasher drain connectors.

Is My Septic Tank Big Enough

Ask your local septic-system investigator whether or not your septic tank is big enough to accommodate food waste. Often, homeowners end up using a garbage disposal with a small septic tank, which results in premature filling and a host of other problems. If your septic tank is small too, you should either avoid getting a garbage disposal or make the septic tank larger.

Does The Garbage Disposal Break Food Down Finely

Any garbage disposal that doesnt make fine particles out of the food waste isnt suited for septic. The reason is simple: the smaller the waster, the quicker it decomposes in septic. Also, you can give a garbage disposal brownie points if it adds any enzymes to help facilitate the speedier breakdown of food waste.

Users Who Are Viewing This Thread

DIYorBust said:I’m quite close to making it without having to lower the drain. From the bottom of the stub out to the bottom of the disposer discharge tube I have about 1.75 inches. It seems like some other forum members had luck making the trap with a low inlet j-bend. It seems like that could work.As long as the bottom of the discharge is above the trap weir it should fully drain right?

Reach4 said:Yes. To be clear, the disposal output is higher than the trap adapter. 1.75 inches is more than enough.A straight discharge tube may work better for you. Maybe you will need to shorten the curved discharge tube a bit.

DIYorBust said:Thank you, that should buy me a little extra room. Is it necessary that the bottom of the disposal output be completely above the top of the trap adapter? Or would it be okay if they overlap half and inch or so? It seems like the water would still drain out, am I right to assume this?

Terry said:Unless you spin the disposer, water will remain if the drain in the wall is higher than the disposer drain.I see it all the time with the new granite counters and 10″ deep sinks. We used to plumb for sinks that were 8″ to 6″

Removing Your Old Garbage Disposal

Step 1: Turn off the electricity

Find your breaker box and cut the circuit breaker that provides power to the plug that your disposal plugs into under your sink. This is for your safety as well as safety of your new unit. This will also ensure that power to your dishwasher is off if you have a dishwasher.

Step 2: Disconnect the drain tube

Use a wrench to disconnect the drain line where it connects to the disposal discharge tube.

Step 3: Loosen the fastening hardware

Your current garbage disposal will have bolts connecting your drain to the top of the garbage disposal unit. Loosen these using a screwdriver.

Step 4: If you have a dishwasher, remove the discharge hose

Next, if you have a dishwasher, you’ll need to loosen the clamp that connects the dishwasher discharge hose to the disposal unit. Just use your screwdriver for this as well.

Step 5: Remove the old disposal unit

Note: You’ll either need a second set of hands or want to prop a box under the unit to support it when it comes loose from the drain.

Locate the 3-tab ring where the top of your old disposal unit joins with the drain. Using either your hands or a screwdriver inserted into one of the 3 tabs, rotate the ring counterclockwise until the old unit releases from the drain. Voila! Your old garbage disposal has been removed. You’re now ready to install your new garbage disposal.

Drain Pipe Too High For Garbage Disposal

They just installed granite countertops with deep sinks. Now if I reconnect everything together the drain pipe from the wall is too high. Short of cutting open the wall and lowering the drain pipe is there anything I can do?

So would either of these work?:

It is becoming fairly common in new dishwashers where the manufacturers are pre-installing them. Although this is becoming a regular practice, a home inspector will still call out the lack of a visible high loop. While the person who installed the dishwasher may have seen a pre-installed high loop on the side of the dishwasher and not installed one under the sink, the home inspector has no way of knowing if this is the case and will write it up as a defect. It is recommended to check the manufacturing specifications of the dishwasher to see if the high loop is already built in, but most dishwasher manufacturers will still recommend the high loop be added under the sink during installation.

Garbage Disposals The Sewers And Septic Tanks

Garbage disposals are good for the busy home plumbing system because it can grind up the food particles that would otherwise sneak down the drain whole, but some sewer and septic systems are not equipped to handle the direct food debris. The chemical environment may not be capable of deteriorating the waste efficiently and some municipalities will have rules in place to ensure the sewer is kept healthy. If youre on a sewer, its a good idea to check with your local regulations before installing a garbage disposal.

With septic tanks, a garbage disposal adds to the amount of waste and water that goes into the tank. It may be a minimal amount, depending on how often the disposal is used, but it can have an impact on how quickly the tank fills. Always make sure to choose a garbage disposal with a high horsepower if you have a septic system. There are disposal models specifically designed to work with septic tanks to help reduce the load. These disposals grind the food waste very fine, and inject an extra dose of important enzymes and microorganisms that help the food waste deteriorate in the tank.

Check your areas recommendations for expected care of the septic system, because the added solid wastes from a garbage disposal can add to the buildup, which could result in more frequent pumping.

Proper Care To Avoid Drain Pipe Clogs

Taking proper care of your garbage disposal will help mitigate clogs. Even when your garbage disposals drain is lower than the unit itself, it can still get clogged.

Moreover, the garbage disposal itself can get clogged. So, what can you do to avoid this?

There are several things you can do to help avoid clogs in your garbage disposal. They include:

• Only sending down biodegradable materials
• Cut down the chunks of food beforehand
• Using soft or rotten food
• Using cold water whenever you use the garbage disposal
• Regularly cleaning the garbage disposal to remove grime buildup
• Using the garbage disposal regularly to keep it working properly

The food you put into the garbage disposal has an impact on its efficiency and its ability to avoid clogging. If you were to put down potato peels, nuts, or shells, it could lead to the garbage disposal clogging quickly.

There are a few different drain variations used for garbage disposals, including:

• Drain line connected to the garbage disposal through an air gap
• Drain line connected directly to the drain through an air gap
• Drain line situated in a high loop to the disposal
• Drain line situated in a high loop directly to the drain

If you decide to install the garbage disposal by yourself, make sure you check local codes before starting. Some areas have specific codes that dont allow disposals due to limits on sewer capacity. Other areas may require air gaps if the disposal is used in tandem with a dishwasher.

Additionally, some areas dont allow plumbing work to be done by anyone other than a licensed professional.
