Tees direct flow into and out of the trap at the correct depth. Missing or broken tees allow floating grease to escape into the sewer line.

This is one of the most common and necessary grease trap repairs.

Flow Control Device Repair in Kirkland
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 essential for a trap to pass inspection.
Clogged Grease Trap Repair in Kirkland
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 stubborn 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 exact location and nature of the clog is crucial for effective repair and long-term performance in your Kirkland establishment.
Lid, Gasket and Riser Repair in Kirkland, WA
Damaged lids and failed gaskets let odors escape and create safety hazards. Outdoor risers can crack from vehicle traffic or ground movement. We replace lids, install new gaskets and repair or replace risers. Traffic-rated lids are installed where trucks or cars drive over the interceptor. These repairs keep odors in and keep people safe.
Grease Trap Leak Repair in Kirkland
Leaks can come from cracked trap bodies, failed gaskets or loose pipe connections. Indoor leaks can damage floors and create slip hazards in the kitchen. We locate the source and replace gaskets, seal fittings or repair cracks when possible. Outdoor leaks can contaminate soil and lead to odors around the building. If the body is badly damaged, we recommend replacement.
Residential Grease Trap Repair in Kirkland, WA
Even residential properties in Kirkland, WA can benefit from a grease trap, especially those with septic systems or older plumbing. If your home's under-sink grease trap is backing up or emitting foul odors, it indicates a need for repair. We service smaller, often plastic or fiberglass, residential units, clearing blockages and fixing minor leaks to protect your home's drain lines from grease accumulation. This prevents expensive main line clogs down the road.

Damaged Baffle Repair in Kirkland
The baffles inside a grease trap are critical for separating FOGs from wastewater. If these baffles are corroded, broken, or dislodged, the trap's efficiency plummets, 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 Kirkland.
