Grease Trap Leak Repair in St. Louis
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 suggest replacement.

Leaking Grease Trap Repair in St. Louis, MO
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 locate 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 St. Louis, MO.
Damaged Baffle and Lid Repair in St. Louis, MO
The internal baffles of a grease trap are crucial for separating FOG from wastewater. If these are damaged or dislodged, the trap becomes inefficient, allowing grease to escape into the sewer system. We repair or replace broken baffles and cracked lids in St. Louis, MO, ensuring your trap functions as designed. A secure lid also prevents odors and keeps pests out, maintaining hygiene around the unit.
Hydro-Jetting for Grease Trap Repair in St. Louis
When traditional snaking isn't enough, hydro-jetting is our go-to method for severe grease trap blockages. This powerful technique uses high-pressure water streams to thoroughly scour the interior of pipes and the grease trap itself, removing years of FOG buildup, scale, and debris. It's a highly effective, non-invasive method that not only clears clogs but also cleans the lines, greatly reducing the likelihood of future blockages in your St. Louis business.
Grease Trap Repair vs Replacement Cost in St. Louis, MO
Simple repairs like gasket or tee replacements usually cost far less than a new trap. Major damage such as a cracked tank body, failing concrete or a badly corroded steel unit may make replacement the better value. We compare repair cost, remaining life and compliance risk for you. Older steel traps often rust through and are good candidates for upgrade. We give you options and pricing in writing so you can make the call.
Flow Control Device Repair in St. Louis
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.
Residential Grease Trap Repair in St. Louis, MO
Even residential properties in St. Louis, MO 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 giving off 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.

Clogged Grease Trap Repair in St. Louis
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 exact location and nature of the clog is crucial for effective repair and long-term performance in your St. Louis establishment.
