Damaged Baffle Repair in Waltham
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 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 Waltham.

Grease Trap Repair vs Replacement Cost in Waltham, MA
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 decide.
Flow Control Device Repair in Waltham
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.
Hydro-Jetting for Grease Trap Repair in Waltham
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 very effective, non-invasive method that not only clears clogs but also cleans the lines, greatly reducing the likelihood of future blockages in your Waltham business.
Inlet and Outlet Tee Repair in Waltham, MA
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. We replace damaged tees with durable PVC or other approved materials. We also check that they are set at the right depth for your unit. This is one of the most common and necessary grease trap repairs.
Baffle Repair and Replacement in Waltham
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 compliant.

Frequently Asked Questions About Grease Trap Repair in Waltham
The cost of grease trap repair in Waltham varies widely depending on the nature and severity of the problem. Minor clogs might range from $200 to $400, while more extensive repairs like replacing baffles or fixing large leaks could be $500 to $1,500 or more. We provide a written estimate after a thorough inspection.
Most indoor repairs take a few hours. Outdoor interceptor repairs may take a day or more, especially if pumping, excavation or concrete work is needed.
Grease traps are smaller, usually located inside or near the kitchen, and are suitable for low-volume establishments. Grease interceptors are much larger, often installed underground outside the building, and are designed to handle the high FOG volumes from large restaurants and commercial facilities. Both serve the same purpose of preventing FOGs from entering the sewer system.
Persistent odors, grease in downstream lines, leaks around the trap, slow drains and broken lids are common signs. If cleaning does not fix the problem, a repair is likely needed.
Our plumbers are experienced in repairing all major brands and types of commercial grease traps and interceptors, including but not limited to Zurn, Big Dipper, Schier, Proceptor, and Rockford Separators. We have access to parts and expertise for a wide range of models commonly found in Waltham, MA.
Yes, BWM Plumbing stands behind the quality of our work. All our grease trap repairs come with a warranty on both parts and labor. The specific terms of the warranty will be clearly outlined in your service agreement, giving you peace of mind.
Minor repairs typically do not, but major structural repairs or replacements may require a permit and inspection. We let you know before starting work.
The primary cause is the accumulation of FOG (Fats, Oils, and Greases) which solidifies and creates blockages. Other causes include structural damage from age or impact, corrosion of internal components, improper installation, or lack of regular maintenance and cleaning.
