The basics

What a grease trap does, and why FOG matters

FOG, fats, oils, and grease, is the enemy of every commercial kitchen drain. A grease trap or interceptor captures it before it reaches the sewer, where it hardens, clogs lines, and causes backups for you and the whole system. Because of that, jurisdictions require food-service businesses to have a properly sized, maintained grease trap, and they enforce it. We handle the full picture: sizing the right unit for your kitchen, installing or replacing it to code, repairing what fails, and making sure it is sized and installed to pass inspection.

How it works

Sized right, installed to code

The right trap, the right size, and the paperwork to prove it.

1

Assess your kitchen

We look at your fixtures, flow, and local FOG rules to determine what your kitchen requires.

2

Size the unit

We calculate the correct trap or interceptor size, undersized units fail and oversized ones waste money.

3

Install or replace

We install to code with proper venting and access, and pull permits where required.

4

Pass inspection

We pull permits where required and document the sizing and install, so it clears inspection.

Catch it early

Signs your grease trap needs service

A grease problem in a commercial kitchen escalates fast. These signs mean it is time to call.

Slow or backing-up kitchen drains

Grease buildup in the trap or line shows up first as sluggish, then backed-up kitchen drains.

Foul odors in the kitchen

A grease trap that is full or failing puts sewer and grease odors into your space.

Renovating or adding equipment

New cooking equipment or a remodel can change your required trap size and compliance.

Failed or flagged inspection

A citation or warning from the jurisdiction means your trap needs service, repair, or replacement.

Undersized for your volume

A trap too small for your kitchen overflows grease into the sewer, the exact thing it should prevent.

Opening or expanding a kitchen

New and expanding food-service spaces need the right trap sized and installed before you open.

Types of grease traps

We help you pick the right type and size for your kitchen, your volume, and your local rules.

Under-Sink Traps

Compact hydromechanical traps that fit under or beside kitchen sinks for lower-volume kitchens.

In-Ground Interceptors

Large-capacity interceptors buried outside, for high-volume restaurants and shared kitchens.

Automatic Units (GRU)

Automatic grease removal units that skim and collect grease continuously, with less manual cleaning.

FOG rules in Maryland

Why this matters in Maryland

Here is the catch: grease trap and FOG requirements are not the same everywhere. They vary by county and municipality across Maryland, sizing formulas, cleaning frequency, recordkeeping, and what counts as compliant all differ between jurisdictions and water authorities. As a local contractor, we know the rules where your business operates, so your trap is sized and serviced to the standard your inspector actually uses.

  • Requirements differ by county and municipality
  • We size to your jurisdiction's FOG formula
  • We document sizing and installation for inspections
  • Avoid fines, citations, and surprise shut-downs

Absolute best plumbers I have ever used. Needed them a few times recently and each time they were so professional, kind and resolved each problem the first time around. This last issue took them several hours to fix. They explained everything along the way and gave a very fair price for a lot of work. They also work very cleanly! I will never use another plumber!

I needed a water valve installed for my new fridge and a new faucet installed in upstairs bathroom. Seth was amazing. He came out and really listened to me and my concerns. We even called the company that was going to deliver my new fridge so he would have a better understanding of what he needed to do his job. It made me feel at ease with the whole process. He is even coming back later in the week to install new fridge once it’s delivered. I will absolutely call them again.

We had a pinhole leak suddenly appear in our outdoor hose bib, and Clarksburg Plumbing was able to provide next-day service, which we really appreciated. Our technician, John Brown, arrived right on time after giving us a 30-minute courtesy call. John quickly diagnosed the problem, explained everything clearly, and provided an accurate assessment of what needed to be done. He completed the repair in under two hours, and the quality of his work was excellent. Before leaving, he even took the time to share some helpful tips on how to prevent similar issues in the future. John was friendly, professional, knowledgeable, and efficient from start to finish. We couldn’t have asked for a better service experience. I highly recommend Clarksburg Plumbing and especially John Brown for anyone needing reliable, high-quality plumbing work.

They also answered all our questions patiently and taught us a lot of why they made the decisions they made. We are very pleased with their work and plan to recommend them and all of Clarksburg Plumbing to our friends and neighbors.

We had a clog in our septic line. The Clarksburg Plumbing crew located the troublesome area using a camera and then removed the clog and tested the line. They then remounted the toilet with a new wax ring and cleaned the area. Overall, a great experience!

Seth was absolutely amazing! He was very courteous and knowledgeable about his profession. He arrived on time and worked the entire time. He kept me in the loop the entire way as to what he was doing. He diagnosed two leaks within our toilet system and readily fixed them. Clarksburg Plumbing should be honored to have such an amazing employee as him.

Good questions

Grease trap FAQ

What restaurant owners and operators ask us most.

FOG stands for fats, oils, and grease. In a commercial kitchen it washes down drains, then cools and hardens in the sewer, causing clogs and backups. A grease trap or interceptor captures FOG before it leaves your building, which is why jurisdictions require one for food-service businesses.

Yes. Sizing, cleaning frequency, and recordkeeping requirements vary by county, municipality, and water authority across Maryland. We know the local rules where your business operates and size and service your trap to that standard.

If the unit is the right size and structurally sound, repair, a baffle, lid, or inlet, is usually the fix. If it is undersized, badly corroded, or no longer compliant, replacement is the better call. We give you the honest recommendation.

It depends on your fixtures, flow rate, and your jurisdiction’s formula. An undersized trap overflows grease into the sewer and fails inspection, while an oversized one wastes money. We calculate the correct size for your kitchen.

Yes. We focus on grease trap installation, replacement, and repair, and we hydro-jet grease-clogged kitchen drain lines to keep them flowing. We do not provide routine grease trap pumping, but we can point you to a service for that.

Absolutely. We size and install the right trap or interceptor as part of a kitchen build-out, coordinated with the rest of your plumbing and your opening schedule.

We serve Clarksburg, Germantown, Gaithersburg, Rockville, Damascus, Potomac, North Bethesda, and the surrounding Montgomery and Frederick County area.
