North Potomac Garbage Disposal Replacement & Drain Reroute

By HiTrend Plumbers

Garbage disposal replacement in North Potomac, MD: a homeowner-supplied American Standard unit installed, the kitchen sink drain rerouted to set it up, and no leaks when tested.

After: The kitchen drain connections under the sink after the work.

The problem

A returning North Potomac customer had a new garbage disposal on hand and needed it installed in place of the old Badger unit under their kitchen sink. They sent a photo of the setup and asked us for a quote to install it.

What our technician found

The new disposal couldn't simply go in where the old one was. The kitchen drain line had to be rerouted to set up the new unit. This is a common part of a garbage disposal installation: disposals vary in size, and the drain outlet on a new unit may not line up with the existing plumbing under the sink.

What we did

  1. Removed the old garbage disposal from under the kitchen sink.
  2. Installed the new disposal the homeowners supplied.
  3. Rerouted the kitchen drain line to set up the new disposal.
  4. Tested the new disposal and confirmed there were no leaks.

Parts used

  • American Standard Slim-Line 1¼ HP garbage disposal (supplied by the homeowners)

The result

The new garbage disposal is installed, the kitchen drain line is rerouted to set it up, and there were no leaks when it was tested.

Tips for North Potomac homeowners

  • Repair or replace? Water leaking from the body of a disposal usually means it's time to replace the unit. A leak at a drain connection is often a simpler fix.
  • If you're buying your own disposal, compare its size with your old unit and measure the space under the sink before you order. Slim-line models are made to take up less room in the cabinet.
  • Tell your plumber if your dishwasher drains through the disposal. On a new unit, the dishwasher inlet is usually blocked by a knockout plug that has to be removed before the hose is connected.
  • A clear photo of the setup under your sink helps a plumber plan the install and spot drain changes ahead of time.
  • After a new disposal goes in, run water and look under the sink for drips at the drain connections during the first few uses.
