Leaking Grease Trap Repair in Grand Forks, ND
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.

Addressing leaks promptly is essential to maintain a sanitary environment and avoid costly remediation in Grand Forks, ND.
Grease Trap Drain Line Repair in Grand Forks
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 Grand Forks, we diagnose and repair issues within these connecting pipes, including clearing FOG accumulation, fixing collapsed sections, or repairing root intrusions. Making sure these lines are clear is vital for the overall efficiency of your grease trap system.

Grease Line Clog Repair in Grand Forks, ND
Grease that hardens in the lines before or after the trap can cause backups even when the trap itself is clean. We use hydro jetting to clear the pipe and remove buildup. A camera inspection helps us confirm the line is clear and check for damage. If we find broken or sagging pipe, we can repair the section. This keeps water and waste moving freely.
Flow Control Device Repair in Grand Forks
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.
