A grease trap that isn’t cleaned on time can quickly turn into a disaster for any restaurant or commercial kitchen. From foul smells to full-blown backups, these warning signs are more than just inconveniences — they can lead to health violations, costly repairs, and even kitchen shutdowns.

Knowing the signs your grease trap needs immediate pumping helps you act before it’s too late.

Top Warning Signs Your Grease Trap Is Full

1. Foul Odors Around the Kitchen

When grease, oils, and food waste sit too long in the trap, they decompose and release strong, unpleasant smells. If customers or staff notice sour or rancid odors, it’s a sign your trap needs service now.

2. Slow or Clogged Drains

If sinks or floor drains are draining slower than usual, grease buildup is restricting water flow. Left untreated, this will turn into a full backup.

3. Grease Layer Visible on Top

Open your trap lid and check. If you see a thick grease cap on the surface, it’s past time for a pump-out.

4. Overflow or Backups During Service Hours

One of the most urgent red flags. Overflowing sinks, dishwashers, or floor drains can force an immediate kitchen shutdown.

5. Health Inspector Red Flags

In Washington, Idaho, and Idaho, inspectors often check grease trap logs. If your service history is outdated, you could face fines — or worse, closure.

What Happens If You Wait Too Long?

• Costly Plumbing Repairs – Backups can damage pipes.

• Lost Business Revenue – Kitchen downtime during peak hours.

• Health Code Fines – Violations can cost $500–$1,000+ per incident.

• Unhappy Customers – Bad odors and slow service drive diners away.

In short, waiting always costs more than routine maintenance.
