Plumbing issues in a restaurant can lead to costly repairs, health code violations, and disruptions to service. Understanding these common problems and taking preventive measures can help keep your restaurant running smoothly.

1. Clogged Drains and Sinks

Cause: Food scraps, grease, and soap buildup.
Prevention: Install drain strainers, use grease traps, and schedule regular professional drain cleaning.

2. Grease Trap Overflows

Cause: Improper maintenance leading to grease accumulation.
Prevention: Clean grease traps regularly and follow recommended disposal guidelines.

3. Leaky Faucets and Pipes

Cause: Worn-out washers, corrosion, or high water pressure.
Prevention: Conduct routine inspections and replace faulty parts promptly.

4. Low Water Pressure

Cause: Clogged pipes, faulty pressure regulators, or municipal supply issues.
Prevention: Check pipes for blockages, maintain water pressure regulators, and install a filtration system if needed.

5. Sewer Line Backups

Cause: Grease buildup, food debris, and foreign objects clogging the main sewer line.
Prevention: Ensure only appropriate waste goes down drains and schedule professional sewer line maintenance.
