Garbage Disposal Installation in Northwest Indiana

Adding a garbage disposal to a kitchen that doesn't have one, or replacing an old unit? Downing Plumbing installs garbage disposals throughout Lake, Porter, and LaPorte County — properly wired, mounted, and connected.

GARBAGE DISPOSAL INSTALLATION

Getting the Installation Right the First Time

A garbage disposal installation involves three systems working together: the mounting connection to the sink drain, the plumbing discharge to the drain trap, and the electrical connection. Get any one of these wrong and you'll have leaks under the sink, a disposal that trips the breaker, or a drain that backs up. Downing Plumbing handles all three.

For kitchens that don't have an existing disposal, we assess whether a dedicated electrical circuit is needed (most disposals require a 20-amp circuit) and coordinate with an electrician if new wiring is necessary. For straight replacement jobs — old disposal out, new one in — we typically complete the job in under an hour using the existing wiring and mounting collar.

If your kitchen has a dishwasher, the disposal serves as the dishwasher's drain connection. We make sure the dishwasher drain hose is properly connected to the knockout port on the new disposal and that the drain loop is correctly positioned to prevent backflow. Small detail — big difference in whether the installation works correctly.

Garbage Disposal Installation Process

In and out in one visit — properly mounted, properly connected, properly tested.

1

Assess and Prepare

We check the existing wiring, drain trap configuration, and sink opening to ensure the new disposal will fit and the circuit can handle it.

2

Remove Old Unit

We disconnect and remove the existing disposal (or remove the sink basket strainer if installing where none existed), and clean the mounting area.

3

Mount and Connect

We install the mounting flange and assembly, connect the drain discharge, hook up the dishwasher drain port, and make the electrical connection.

4

Test Everything

We run the disposal with water and check all connections for leaks, verify the switch works, and confirm the dishwasher drain connection is correct.
