How to check if drain line is correctly installed


Is the drain line installed correctly?

Look under your sink and make sure that:

  • The drain hose comes through at the bottom of the cabinet.
  • If you don't have an air gap, make sure the hose is looped so that it touches the underside of the counter (picture below shows arrow pointing at air gap)

  • Check that drain hose clamp is correctly positioned.
