Turn off power first, then unbolt the unit from underneath
Removing a Badger garbage disposal takes about 30 minutes if you have a wrench and a bucket. The first step is non-negotiable: flip the breaker that controls the disposal to the off position, or unplug it if it has a plug. A disposal can start without warning if someone flips the switch while you are working on it, and that will injure your hand.
Once power is off, place a bucket under the disposal to catch water that drains from the sink. Look underneath the sink at the disposal unit itself. You will see a large mounting ring — a metal collar that holds the disposal to the sink drain. This ring has three bolts around it. Use an adjustable wrench to loosen all three bolts by turning them counterclockwise. They do not need to come all the way out; loosen them until the disposal drops slightly and you can wiggle it by hand.
If the disposal is connected to a dishwasher, you will also see a rubber hose clamped to the side of the unit. Loosen the hose clamp with a screwdriver and pull the hose free. This step is straightforward to forget and will stop you cold if you try to pull the disposal down without doing it first.
Disconnect the drain pipes and remove the unit
Below the disposal, you will see two pipes: one coming from the sink and one going to the wall or floor (the drain line). These are usually connected with slip nuts — large nuts you can turn by hand or with a wrench. Turn the slip nut on the incoming pipe counterclockwise and pull the pipe away. Do the same for the drain line going out. Water will spill, so make sure your bucket is positioned to catch it.
Once both pipes are loose, grip the disposal body with both hands and pull it straight down. It will come free from the mounting ring. Set it aside in your bucket or on newspaper to contain any remaining water.
Remove the mounting ring if you are not replacing it
If you are taking the disposal out permanently and not installing a new one, you need to remove the mounting ring from the sink drain. Look at the top of the sink, where the ring sits. You will see a snap ring or a series of tabs holding it in place. Push up on these tabs from underneath or use a flathead screwdriver to pry the ring upward. Once the ring is free, pull it down through the sink opening and set it aside.
If you are installing a new disposal, leave the mounting ring in place. The new unit will bolt to the same ring, so removing it means extra work later. The mounting ring is designed to stay in the sink permanently, and most sinks have it installed from the factory.
Key Takeaways
- Turn off the breaker or unplug the disposal before you touch anything, because the unit can start without warning and cause serious injury.
- Loosen the three bolts on the mounting ring underneath the sink until the disposal drops and you can wiggle it by hand.
- Disconnect the dishwasher hose (if present), the incoming drain pipe, and the outgoing drain line before pulling the unit down.
- If you are not replacing the disposal, remove the mounting ring from the sink drain by pushing up on the snap ring or tabs from underneath.
What to do with the old disposal
A Badger disposal is metal and heavy. Most curbside trash services will not pick it up because it is bulky. Call your local waste management provider or check their website to find out whether they accept appliances at the landfill or transfer station. Some areas charge a small fee for appliance disposal; others do it free.
If the unit still works, you can also list it free on Craigslist or Facebook Marketplace — people often want used disposals for rental properties or repairs. A working Badger disposal typically sells or is claimed within a few days because they are durable machines and parts are inexpensive.
Preparing the sink if you are not installing a new disposal
Once the mounting ring is out, the sink drain opening is exposed and unsupported. You have two options: install a new disposal, or install a standard sink strainer basket (the kind that sits in the drain and catches food). A strainer basket costs $5 to $15 and takes five minutes to install. You straightforward drop it into the drain opening and it sits there by gravity.
If you leave the drain completely open with nothing in it, water will drain but food particles and debris will fall through into the pipes below. This can cause clogs. A strainer basket prevents that problem and is the standard setup for sinks without disposals. Most hardware stores stock them in the plumbing section.
Troubleshooting stuck bolts and tight connections
If the mounting bolts will not turn, spray them with penetrating oil (like WD-40) and wait 10 to 15 minutes. The oil loosens corrosion and makes the bolts easier to turn. If a pipe connection is stuck, try tightening it slightly first — sometimes a stuck nut will loosen if you turn it the opposite direction a quarter turn, then reverse direction. Do not force it; if it will not budge after two attempts, spray it with penetrating oil and wait.
If the disposal itself is stuck in the mounting ring even after the bolts are loose, tap the sides gently with a rubber mallet to break the seal. Do not hit it hard or you may crack the sink. A few light taps usually frees it. If it remains stuck after tapping, spray penetrating oil around the base of the mounting ring and wait another 15 minutes before trying again.
Frequently Asked Questions
Do I need a plumber to remove a disposal?
No. Removal is a straightforward job that requires only a wrench and a screwdriver. The hardest part is usually loosening corroded bolts, which penetrating oil solves. If you are uncomfortable working under a sink or if bolts will not budge after using penetrating oil, a plumber can do it in 30 to 45 minutes for a service call fee.
What if water keeps dripping after I disconnect the pipes?
Some water will always remain in the pipes and the disposal itself. Place your bucket underneath and let it drip for a few minutes. If it continues dripping steadily after five minutes, you may have missed a connection or the pipes may not be fully loose. Check that both slip nuts are completely off and that the hose clamp (if present) is fully open.
Can I remove a disposal without turning off the breaker?
No. Even if you do not touch the switch, someone else can turn it on while you are working, or the switch can be bumped accidentally. A running disposal will cause severe cuts. Always turn off the breaker first and leave it off until you are completely finished and the unit is removed.
What size wrench do I need?
An adjustable wrench works for all the bolts and nuts on a Badger disposal. If you have a set of fixed wrenches, the mounting bolts are usually 1/2 inch or 9/16 inch, and the slip nuts are typically 1 1/4 inch. Start with an adjustable wrench — it fits everything and costs $10 to $20.
