Flow Control Device Repair in Wilmington
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.
Grease Trap Drain Line Repair in Wilmington
Beyond the trap itself, the drain lines leading to and from the grease trap can also suffer damage or blockages. These lines are particularly susceptible to grease build-up. In Wilmington, 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.
Grease Trap Odor Control & Repair in Wilmington
Persistent foul odors coming from your grease trap are a sign of inefficiency, excessive FOG accumulation, or bacterial growth. Beyond cleaning, our repair services address the root cause, whether it's poor ventilation, sludge buildup, or structural issues preventing proper flow. We ensure all components are working correctly to contain and process waste effectively, eliminating unpleasant smells that can deter customers in Wilmington.

For restaurants, cafeterias, and food service establishments in Wilmington, a functioning grease trap is a must.

We work quickly to minimize disruption to your business.

Hydro-Jetting for Grease Trap Repair in Wilmington
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 Wilmington business.
