If you run a restaurant or commercial kitchen in Murrieta, managing grease is one of the most critical parts of your plumbing system. Two of the most common tools used to manage fats, oils, and grease (FOG) are grease traps and grease interceptors. While these terms are often used interchangeably, they have some key differences that affect performance, maintenance, and compliance.
In this blog post, we’ll break down the difference between a grease trap and a grease interceptor, help you determine which one is right for your Murrieta business, and explain why proper installation and maintenance are essential to keeping your kitchen running smoothly.
What Is a Grease Trap?
A grease trap is a small, indoor device typically installed under a sink or near the point of use. It captures grease and solid food particles from wastewater before they enter the plumbing system.
Key Features of Grease Traps:
- Installed indoors (under sinks or prep stations)
- Lower capacity (under 50 gallons per minute)
- Requires frequent maintenance (weekly or biweekly)
- Best for smaller restaurants or low-volume kitchens
Grease traps work well for businesses with light to moderate grease output and limited space.
What Is a Grease Interceptor?
A grease interceptor is a larger tank installed underground outside the building. It serves the same purpose—capturing grease before it enters the sewer—but it can handle a much larger volume of wastewater.
Key Features of Grease Interceptors:
- Installed outside, underground
- Higher capacity (over 50 gallons per minute)
- Maintenance needed every 1–3 months
- Ideal for large or high-volume commercial kitchens
Grease interceptors are the go-to solution for full-service restaurants, cafeterias, and any establishment with a high volume of cooking and dishwashing.
Grease Trap vs. Grease Interceptor: Key Differences
| Feature | Grease Trap | Grease Interceptor |
|---|---|---|
| Location | Indoors, near fixture | Outdoors, underground |
| Size & Capacity | Smaller (under 50 GPM) | Larger (50+ GPM) |
| Maintenance Frequency | Weekly or biweekly | Monthly to quarterly |
| Installation Cost | Lower | Higher |
| Best For | Cafes, food trucks, small kitchens | Restaurants, hotels, high-volume ops |
Knowing the difference between grease traps and interceptors helps you stay in compliance with local Murrieta plumbing codes, which often require specific systems based on kitchen size and output.
Why This Matters for Murrieta Restaurants
In Murrieta, plumbing regulations and health codes require commercial kitchens to manage grease disposal efficiently. Failure to use the correct system—or neglecting to maintain it—can result in:
- Sewer backups
- Foul odors in the kitchen or dining area
- Expensive plumbing repairs
- Fines or shutdowns from health inspectors
Hiring a licensed plumber in Murrieta for proper grease management is one of the best ways to protect your business.
Choosing the Right Option for Your Kitchen
Ask these questions to determine your best fit:
- How many meals do you serve daily?
- Do you have the indoor space for a grease trap?
- Do you have outdoor space for a larger system?
- How often can you commit to cleaning and maintenance?
If you’re unsure, a Murrieta commercial plumber can perform an evaluation and recommend the right solution for your kitchen’s size, menu, and usage.

Whether you choose a grease trap or interceptor, routine maintenance is non-negotiable. Regular service from a professional plumbing company in Murrieta will help:
- Avoid backups and overflows
- Extend the life of your plumbing system
- Keep your restaurant compliant with local regulations
