Garbage Disposal Sink Flange Replacement

A garbage disposal flange is a rubber gasket that creates a watertight seal between the garbage disposal and the sink drain. Over time, the flange can become worn or damaged, which can lead to leaks. If you notice a leak around your garbage disposal, it's important to replace the flange as soon as possible to prevent further damage.

Replacing a garbage disposal sink flange is a relatively simple task that can be completed in about 30 minutes. Here are the steps on how to do it:

  1. Turn off the water supply to the sink. This is usually done by turning off the valves under the sink.
  2. Disconnect the garbage disposal from the sink drain. To do this, loosen the nuts that hold the disposal in place. Be careful not to drop the disposal.
  3. Remove the old flange. The flange is usually held in place by a few screws. Remove the screws and then pull the flange off of the disposal.
  4. Clean the area where the flange was located. Remove any old sealant or debris. This will help the new flange to seal properly.
  5. Apply a bead of silicone sealant around the edge of the new flange. This will help to create a watertight seal.
  6. Install the new flange onto the disposal. Align the flange with the holes on the disposal and then tighten the screws.
  7. Reconnect the garbage disposal to the sink drain. Tighten the nuts until the disposal is secure.
  8. Turn on the water supply to the sink and check for leaks. If you see any leaks, tighten the nuts or screws until the leak stops.

Here are some additional tips for replacing a garbage disposal sink flange:

  • Use a new flange that is the same size and shape as the old flange.
  • Apply a generous amount of silicone sealant to the new flange.
  • Tighten the nuts and screws until the flange is secure, but do not overtighten.
  • Check for leaks after you have turned on the water supply.

Replacing a garbage disposal sink flange is a simple task that can be completed in about 30 minutes. By following these steps, you can prevent leaks and keep your garbage disposal working properly.
