Common Symptoms & Causes
The following symptoms indicate a Universal Xpress Mount leak on your Moen Host Series GXS75C garbage disposal.
🔨 Pro Tip from Dave
On the GXS75C, a common mistake technicians make is only replacing the upper sink flange gasket and ignoring the three-bolt mount assembly cushion ring beneath it — part of the Moen Xpress Mount Kit — which hardens and distorts over time and is almost always the true source of the leak. Make sure to inspect and reseat all three mounting tabs evenly, because an uneven mount on this model will cause persistent dripping even with a brand-new gasket installed.
- Water pooling directly beneath the sink flange where the disposal mounts
- 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
This issue is typically caused by a worn or deteriorated sink flange gasket, failed plumber’s putty seal, or a cracked Universal Xpress Mount ring that has loosened over time with regular use.
