Possible Causes

Incorrect splash guard size, Guard not fully seated in flange, Partial drain blockage causing water to surge upward, Excessive water flow into disposal

How to Fix / Troubleshooting

Safety First: Keep face and hands away from the opening while running. Turn OFF power before adjusting the guard.

  • Step 1 – Verify guard seating: Press the splash guard firmly into the AmazonCommercial sink flange until it is fully seated.
  • Step 2 – Replace with correct guard: If the guard is loose or undersized, install the correct model designed for your disposal.
  • Step 3 – Check for drain restriction: Clean the P-trap and discharge piping to ensure water can exit freely.
  • Step 4 – Moderate water flow: Reduce faucet flow slightly during operation.
