Garbage Disposal Installation and Repair — Affton, MO, Plumber

What a Typical Garbage Disposal Installation Looks Like in Affton, MO

Setting up a new garbage disposal in your home can require multiple forms of experts, thanks to the electrical and plumbing components. If this is a replacement, you'll need to remove the old unit, replace the mounting assembly, and hook up the new disposal. We'll go over each step in more detail below:

Step 1: Prepare the Site:
Before touching the garbage disposal itself, it's important to prepare the site. It's essential to turn off power in this section of the house, and to make sure nothing is running through the drains at the time. For renovations, your plumber and electrician will coordinate to make sure that the proper wiring is available, but not live.

Step 2: Disconnect and Remove Current Disposal (As Applicable)
Before installing a new unit, you need to make space for it. If you have an existing unit, it will need to be taken out. Your plumber will remove the electrical assembly, mount, flange, and the unit itself.

Step 3: Set Up New Mounting Assembly
The mounting assembly connects your garbage disposal to the sink. With several parts that each require their own precision fastening, it's important to work with an expert. Without expert help, you could end up needing sink repairs, too.

Step 4: Connect the New Unit
Now that your sink is prepared, your plumber can put the new garbage disposal into place. With it connected to the mounting assembly, it can be connected to a power source.

Step 5: Connect Garbage Disposal Discharge to Sewage Pipe
Now that your sink drains down into your new garbage disposal, the unit itself needs to drain into the sewage. Your Affton, MO, plumber will set up a discharge pipe that leads to your home's sewer line.

Step 6: Connect to Dishwasher (As Applicable)
For Affton, MO, homes with dishwashers, it's important to connect your new disposal to it through a discharge hose. This sends wastewater from the dishwasher into the disposal unit, where any remaining food scraps can be ground up, minimizing the chance of a clogged pipe.

Now that the installation is complete, our team won't leave before checking for any problems with how the new unit is functioning. We don't consider your garbage disposal installation done until everything is working properly and efficiently.

6 Signals That You Need to Look For Garbage Disposal

When your garbage disposal isn't working properly, it can cause headaches, lead to you spending extra time on your dishes, and potentially even result in property damage. Watch out for these six signs that you need a new garbage disposal:

  1. Renovation/New Construction: When designing your next kitchen, consider whether it will include a garbage disposal.
  2. Leaks: Look out for puddles or damp spaces under your sink.
  3. Current Disposal Won't Turn On: This is probably the clearest sign: There's no reason to put up with a non-functional unit.
  4. Unit Turns On, But Isn't Grinding: Even if your unit is receiving power, it might have something wrong that prevents it from working.
  5. Repeated Jams: Your unit will be more likely to jam as the internals and blades wear out.
  6. Slow Drains: Slow drains are a precursor to clogs. The more consistently your sink is draining slowly, the more likely you need a new garbage disposal.

If you suspect something's wrong with your disposal, but aren't certain whether or not it needs a replacement, our plumbing experts also offer garbage disposal repair services in Affton. Our commitment to our customers is to give you real, expertise-based recommendations, not just sell you on a new purchase.

Make Your Garbage Disposal Last

The number one mistake people make with their garbage disposals is what they try to use it for. While these machines can handle a lot, they are not magic. Don't put fats, oils, grease, bones, or non-food items down the drain. Misusing the disposal can quickly lead to damage, whether to the blades or by straining the internals.

When you do run your disposal, be sure to use cold water. This will help scraps move down the drain and out into your sewer line, instead of getting stuck. If you're a person who doesn't need to use your garbage disposal regularly, you should still run it once a week with ice cubes and/or lemon rinds, and scrub it (safely) once a month. Taking these simple steps will protect your disposal's blades and keep it operating effectively.

Composting: Your Garbage Disposal's Sidekick

Composting is another tool you can use to protect your garbage disposal. Whether at home or through a commercial service, it gives you an alternative way to dispose of larger food scraps (and more). Either at home or through a commercial process, this can reduce your food waste that goes down the drain, and give it another way to benefit you.

There are several benefits to composting: You can extend the lifespan of your garbage disposal, protect the environment, and often reduce gardening costs.

The following materials are typically eligible for composting in Affton, MO:

  • Coffee Grounds
  • Raw fruits and vegetables
  • Eggshells
  • Houseplants
  • Plain paper napkins
  • Cardboard
  • Tea bags
  • Meat*
  • Fish*
  • Bones*
  • Dairy*

*These products can be composted, but are not recommended for at-home composting. Look for commercial composting services for these materials.

4 Dangers of Ignoring a Broken Garbage Disposal

Even though garbage disposal issues aren't the most critical of plumbing problems, they still should be addressed sooner rather than later. What starts out as a small stain can quickly turn into significant property damage.

Here are four of the risks you face by not repairing or replacing your garbage disposal:

  1. Massive clogs can occur as larger food scraps get stuck in your sewer line, creating a drain cleaning issue.
  2. Pipe damage can come from the larger scraps going down the drain, necessitating repairs.
  3. Leaks are a risk anywhere in your sewer line, including difficult-to-detect spots.
  4. Slow drains and standing water will smell foul and attract pests as debris builds up.

If you want to avoid all of these, even though a broken garbage disposal isn't a plumbing emergency, it's a good idea to talk with a plumber soon after noticing the problem.

Affton, MO, Garbage Disposal Use, Repair, and Installation FAQs

What is the typical lifespan of a garbage disposal?

A typical garbage disposal will last 8-15 years. Some easy steps you can take to maximize its lifespan are regularly cleaning it, running ice through it, and only sending safe materials (like small food scraps) down it.

What materials aren't safe to put down your garbage disposal?

Protect your garbage disposal by finding alternative disposal methods (such as composting) for the following products:

  • Fats
  • Coffee Grounds
  • Eggshells
  • Corn Husks
  • Large Quantities of Food Waste
  • Non-Food Items

Is there something you should do before installing a new garbage disposal?

There isn't a perfect guide to what prep work you'll need to do, but one rule of thumb is this: Installing a new garbage disposal will generally take more prep work than a replacement. If you're installing a garbage disposal in a new home, or in an existing kitchen that doesn't have an old one, you'll need the electrical work, sink installation, and pipe laying to be complete. Be sure that you have all the proper permits before starting.

Most of the time, a replacement does not require as many permits or contractors. You will need to turn off electricity in the affected part of your house, but your local Affton, MO, plumber can take care of the installation after that.

Why should you get a garbage disposal in Affton, MO?

A garbage disposal can be an asset in your kitchen, helping you save time, spend less energy on cleanup, prevent clogs, and reduce your trash output.

Should you pour boiling water into your garbage disposal?

We do not recommend pouring boiling water down your garbage disposal. While hot water can sometimes play a role in cleaning, boiling water can damage the softer, plastic components of your unit. It can also melt oils, allowing them to gum up the inner workings.

Should you use chemical drain cleaners for your garbage disposal?

We do not recommend the use of chemical drain cleaners, either for your garbage disposal or your pipes in general. They are made up of corrosive, often harmful materials that can damage the disposal unit, dull the blades, and hurt the sewage pipes below. Additionally, they could void the warranty on your unit.

Should you use hot or cold water when running your garbage disposal?

You should run cold water while using your garbage disposal. Running hot water can melt greases, creating problems when they get into the inner workings. Running the disposal with no water flow doesn't risk this, but can increase wear and tear on the unit.

How should you clean your garbage disposal?

You should deep-clean your garbage disposal once a month. It's easy to do so in 4 simple steps: 1. Turn off the disposal. 2. Turn on hot, but not boiling, water. 3. Take a long handled cleaning brush and prep it with soap. 4. Thoroughly scrub the blades and surrounding parts of the disposal, without reaching your hand in and potentially hurting yourself.

In between cleanings, keep your blades sharp by running ice cubes through the disposal every week.
