Commercial Grease Interceptor Repair in San Mateo, CA
Larger commercial establishments often use grease interceptors, which are more substantial than standard grease traps. These systems require specialized knowledge for repair, often involving more complex piping and larger capacity tanks. Our technicians are trained in the repair of all types and sizes of commercial grease interceptors, ensuring your high-volume kitchen in San Mateo, CA remains compliant and functional, regardless of the system's complexity.
Grease Trap Drain Line Repair in San Mateo
Beyond the trap itself, the drain lines leading to and from the grease trap can also suffer damage or blockages. These lines are especially susceptible to grease build-up. In San Mateo, we diagnose and repair issues within these connecting pipes, including clearing FOG accumulation, fixing collapsed sections, or repairing root intrusions. Ensuring these lines are clear is vital for the overall efficiency of your grease trap system.
Leaking Grease Trap Repair in San Mateo, CA
A leaking grease trap can cause significant property damage, foul odors, and potential health code violations. Leaks often stem from corroded tanks, cracked seams, or failing pipe connections. We use leak detection techniques to pinpoint the source and provide targeted repairs, which may involve patching the tank, sealing connections, or replacing damaged sections of the trap or associated plumbing. Addressing leaks quickly is essential to maintain a sanitary environment and avoid costly remediation in San Mateo, CA.
Baffle Repair and Replacement in San Mateo
Baffles slow incoming water so grease can rise and solids can settle. When baffles crack, corrode or break loose, grease passes straight through the trap. We remove damaged baffles and install new ones made for your trap model. In concrete interceptors, we can repair or rebuild baffle walls. Restoring baffles brings back proper separation and helps you stay up to code.
Flow Control Device Repair in San Mateo
Hydromechanical traps rely on a flow control fitting to keep water moving at the rated speed. If this fitting is missing or clogged, the trap can be overwhelmed and grease escapes. We inspect, clean or replace flow control devices during repair visits. We also check the air intake that allows the device to work properly. Correct flow control is necessary for a trap to pass inspection.
Damaged Baffle Repair in San Mateo
The baffles inside a grease trap are essential for separating FOGs from wastewater. If these baffles are corroded, broken, or dislodged, the trap's efficiency drops sharply, allowing grease into the sewer system. Our service includes inspecting the condition of all baffles and repairing or replacing them as needed, often using durable, corrosion-resistant materials. Proper baffle function is key to compliance with wastewater regulations in San Mateo.

Clogged Grease Trap Repair in San Mateo
Grease traps often clog due to excessive accumulation of fats, oils, and grease (FOGs) or food solids. Our technicians use high-pressure hydro-jetting to break down tough blockages and thoroughly clean the internal baffles and lines. We also inspect for underlying issues like damaged pipes or improper disposal practices that contribute to repeat clogs, offering solutions to prevent future blockages. Identifying the precise location and nature of the clog is crucial for effective repair and long-term performance in your San Mateo establishment.

Minor repairs like clearing a clog or replacing a gasket usually do not require a permit.

For minor repairs like clearing a clog or replacing a baffle, permits are typically not required.

We can advise you on permit requirements during our assessment.
