Epoxy-Coated Steel
A practical fabricated-metal option with a protective coating inside and out. Well suited to many conventional custom applications where shape, size, or connection placement drives the project.

Why go custom?
Your space doesn’t always match a catalog.
A custom interceptor gives your project team more control when a standard size, shape, inlet, outlet, or material is not workable.
We help turn your field dimensions and operating requirements into a purpose-built unit. Custom fabrication can solve tight footprints, unusual pipe alignments, retrofit conditions, high-use applications, and specialized facilities.
- Fit within maximum available length, width, and height
- Place connections around the existing plumbing layout
- Match the appropriate material to the application
- Address new construction, replacement, or retrofit projects
Material choices
Three ways to build the right solution.
Material selection depends on corrosion exposure, operating conditions, available space, budget, and the requirements of the approving authority.
Stainless Steel
A premium, corrosion-resistant choice for demanding environments, exposed installations, and facilities that prioritize durability and an easy-to-clean metal surface.
Premium durabilityDurable Poly
A non-corroding plastic option that can reduce weight and support specialized shapes. Material and structural requirements are reviewed for the specific installation.
Corrosion-resistant plasticImportant: Final sizing, configuration, material, venting, and installation must meet applicable codes and be approved by the local authority having jurisdiction.
Replacement planning
Rust is more than a cosmetic problem.
Advanced corrosion can weaken walls, lids, baffles, and connection points. It can also make cleaning more difficult and may lead to leakage, odors, failed inspections, or an unexpected shutdown.
If an older trap shows heavy scaling, perforation, soft metal, a failing lid, or recurring leaks, document the condition and have the unit evaluated. We can review the existing footprint for a custom replacement—or explore whether a fitted drop-in liner is appropriate.
Send Us the Project DetailsFrom problem to plan
A straightforward custom process.
Start with what you know. Photos, a marked-up sketch, maximum dimensions, or existing plans can help us understand the application.
Share the project
Tell us whether this is a new build, replacement, retrofit, or liner application.
Confirm requirements
Provide dimensions, capacity or flow needs, pipe sizes, connection locations, and material preference.
Review the solution
Our team reviews the information, identifies open questions, and prepares the proposed configuration and quote.
Approve & fabricate
After project details are confirmed and approved, the custom unit moves into fabrication.
Beyond the interceptor
Support for the complete flow system.
Through our relationship with Ryan Herco Flow Solutions, Drain-Net can also help source plastic piping systems, valves, fittings, tanks, measurement equipment, and related fluid-handling components.
This is especially useful for industrial or specialized projects where the interceptor is only one part of a broader waste-management or process-flow system.

Frequently asked questions.
Custom projects vary. These answers provide a useful starting point before the detailed review.
When is a custom grease trap needed?
A custom unit may be appropriate when the available footprint, connection locations, required capacity, chosen material, or replacement conditions cannot be addressed by a standard model.
What information should I send first?
Send the project city and state, maximum available dimensions, desired capacity or flow rate, pipe sizes, connection locations, material preference, timing, photos, and any plans or specifications you have.
Can you duplicate an old or obsolete unit?
Often, yes. We can review photographs, measurements, drawings, connection locations, and the original specifications when available. The replacement still needs to satisfy current project and local approval requirements.
Do you determine what local code requires?
We can help develop the product around your stated requirements, but the project owner, engineer, installer, and local authority having jurisdiction are responsible for confirming the required type, sizing, approvals, and installation.
Can a liner always replace a failing grease trap?
No. A liner is a project-specific option. The existing structure, dimensions, connections, access, service conditions, and local approval requirements must be reviewed before determining whether a liner is suitable.
