Common Symptoms & Causes

The following symptoms indicate a Universal Xpress Mount leak on your Moen Host Series GXS75C garbage disposal.

  • Visible dripping from the top ring of the GXS75C unit during or after running water
  • Dampness or water stains forming on the cabinet floor under the sink
  • Loose or shifting disposal unit that rocks when touched at the mounting assembly
