Professional Garbage Disposal Replacement Cost

The cost of replacing a garbage disposal consists of two components: the cost of the unit and the cost of labor. The cost of the unit depends on the type, size, and material of the garbage disposal. The cost of labor depends on the size and complexity of the installation.

1.      Type of Garbage Disposal

There are two primary types of garbage disposals: continuous feed and batch feed. Continuous feed disposals, which typically cost around $200 on average, are more prevalent and enable you to dispose of waste continuously while the power switch is on. Batch feed disposals, averaging around $300, require you to fill the chamber with waste and cover it with a stopper before activating. They offer enhanced safety and quieter operation compared to continuous feed disposals. When considering replacing a Garbage Disposal, understanding the differences between these types can help you make an informed decision.

2.      Size of Garbage Disposal

The size of the garbage disposal refers to its horsepower (HP), which determines how powerful and fast it can grind food waste. The higher the horsepower, the more efficient and durable the unit is. However, higher horsepower also means higher price and energy consumption. The most common sizes for residential use are 1/3 HP, 1/2 HP, 3/4 HP, and 1 HP. The average prices for these sizes are:

  • 1/3 HP: $50 – $100
  • 1/2 HP: $70 – $150
  • 3/4 HP: $100 – $250
  • 1 HP: $150 – $350

3.      Material of Garbage Disposal

Garbage disposals come in various materials, with aluminum and stainless steel being the most prevalent. Aluminum options are typically cheaper than their stainless steel counterparts, yet they corrode more rapidly and have a shorter lifespan. Conversely, stainless steel garbage disposals are pricier initially, but they offer superior resistance to rust and boast longer durability. When considering which to install, it’s important to weigh the benefits and drawbacks of each material carefully, especially if you’re planning to replace a garbage disposal.

  • Aluminum garbage disposals typically cost between $70 and $350.
  • Stainless steel garbage disposals typically cost between $400 and $1,200.

 

4.      Cost of Labor

The cost of labor to replace a garbage disposal hinges on the size and intricacy of the installation. For smaller and simpler installations, a general contractor or handyman can typically handle the job, charging between $50 and $100 per hour. However, for larger and more complex installations, the expertise of an electrician or plumber may be necessary, with hourly rates ranging from $75 to $150. On average, the installation of a garbage disposal takes about one hour, though this timeframe can fluctuate depending on the specific circumstances.

2.      How to Replace a Garbage Disposal Step-by-Step

A garbage disposal is a handy appliance that pulverizes food waste into tiny pieces and sends them down the drain. Nevertheless, it may wear out, develop leaks, jam, or produce loud noises over time. If your garbage disposal isn’t functioning correctly, you may have to Replace a Garbage Disposal with a new unit. Here are the steps to Replace a Garbage Disposall yourself

Step 1: Turn Off the Power and Water

Before you start working on the garbage disposal, you need to turn off the power and water supply to avoid electric shock or flooding. Locate the circuit breaker that controls the power to the disposal and switch it off. Then, turn off the water valve under the sink or at the main water supply.

Step 2: Remove the Old Disposal

Open the cabinet under the sink and locate the Garbage Disposal unit. It’s a large cylindrical object connected to the drain and the plumbing pipes. You’ll need to disconnect the discharge tube, which is the pipe responsible for carrying ground waste out of the disposal. Utilize a wrench or pliers to loosen the nuts or fasteners securing the pipe in place, then pull it out.

Subsequently, you’ll have to detach the disposal from the mounting ring, a metal ring linking the disposal to the sink drain. Grip the disposal with one hand and twist the ring counterclockwise with the other hand until it releases. Exercise caution, as the disposal can be heavy and may contain water and food debris.

To complete the replacement of a Garbage Disposal, follow these steps:

  1. Open the cabinet under the sink to access the garbage disposal unit.
  2. Disconnect the discharge tube, the pipe responsible for carrying ground waste out of the disposal, by loosening the nuts or fasteners that hold it in place.
  3. Detach the disposal from the mounting ring, a metal ring connecting the disposal to the sink drain, by twisting it counterclockwise until it releases. Be cautious as the disposal may be heavy and contain water and food debris.

Step 3: Replace the Mounting Hardware

The mounting hardware comprises a sink flange, a mounting ring, and a rubber gasket. The sink flange is a metal piece that fits into the drain hole of the sink. A metal ring, known as the mounting ring, secures the flange to the sink. Additionally, a rubber gasket serves as a seal to prevent leaks between the flange and the sink.

To replace a Garbage Disposal, start by removing the old sink flange from the drain hole. Utilize a screwdriver to loosen and remove the screws holding the mounting ring in place. Then, pry off the old flange using a putty knife or a flathead screwdriver.

Clean the drain hole and apply plumber’s putty around it. Subsequently, insert the new flange into the hole and firmly press it down. Use a rag to wipe off any excess putty. Next, affix the new mounting ring and rubber gasket to the flange from beneath the sink. Tighten the screws evenly until they are snug.

Step 4: Install the New Disposal

Before you install the new disposal, you will need to prepare it for connection. First, check for a dishwasher knockout plug on the side of the disposal. This small metal piece blocks the dishwasher inlet. If you have a dishwasher, you’ll need to remove this plug with a hammer and a screwdriver. If you don’t have a dishwasher, you can leave it in place.

Next, verify if there is an electrical cord attached to your new disposal. If so, you can plug it into an outlet under your sink. If not, you will need to wire it yourself using wire nuts and electrical tape. Follow the manufacturer’s instructions for wiring your disposal.

To Replace a Garbage Disposal, align it with the mounting ring under your sink and twist it clockwise until it locks in place. Ensure it is level and secure. Then, reconnect the discharge tube to your disposal using nuts or fasteners. You may need to cut or adjust the pipe length if it doesn’t fit properly.

Step 5: Test for Leaks and Functionality

After replacing your garbage disposal, you can restore power and water supply and check for leaks and functionality. Run water through the sink and inspect for any drips or wet spots underneath. If you detect any leaks, tighten the connections or apply silicone sealant to remedy them. To verify proper operation of your disposal, plug it in or restore power with the circuit breaker and toggle the switch on the wall or the disposal itself. You should hear a humming sound and observe smooth water drainage. Test by grinding some food scraps to ensure efficient disposal. If your disposal emits unusual noises or jams, immediately switch it off and inspect for obstructions or loose parts.

Congratulations! You have successfully replaced your garbage disposal step by step.
