Keeping your kitchen sink fully operational
A commercial kitchen sink is one of the hardest-working plumbing fixtures on the property. It gets hit with grease, food scraps, and heavy hot water use all day long, so when the drain slows or backs up, service grinds to a halt.
Our technicians have handled kitchen drain cleanout services for commercial properties across the greater Boston area since 1976.
Our goal? To be at your door within 2 hours of your call.
How We’ll Unclog Your Sink
Each of our techs shows up with a commercial-grade electric snake machine. The snake feeds a metal cable into the drain line, spins under motor torque, and scrapes the pipe clean as it breaks through the clog. If snaking reveals a bigger issue in the drain pipe, we bring in video inspection before recommending next steps.
Tips for preventing sink clogs
- Never pour food grease down the kitchen drain. Let it cool, then throw it in the trash.
- If your sink has a garbage disposal, run cold water for 45 seconds after grinding food to flush scraps through the drain line.
- Scrape plates into the trash before rinsing. Even small bits of food build up in the fixture trap over time.
- Schedule a routine kitchen drain cleanout before slow drains turn into full backups.
Signs Your Kitchen Drain Needs a Cleanout
You don’t have to wait for a full clog to call. Early warning signs usually mean grease, food, or scale is building up inside the drain line or fixture trap. A professional cleanout clears it before wastewater starts backing up into the sink. Watch for a slow drain, gurgling from the P-trap or vent, standing water in the basin, or a foul smell coming from the drain stack.
When Snaking Isn’t Enough
Sometimes a stubborn clog points to a bigger problem farther down the drainage system. If video inspection turns up one of these issues, our plumber can walk you through options like hydro jetting or pipe lining:
- Cracked cast iron
- Root intrusion in the main sewer line
- Scale coating the horizontal drainage pipe
- Sagging or offset joints in the drain pipe
- Heavy grease buildup a snake can’t fully clear
Pipe lining restores an old drain pipe from the inside without digging up the concrete floor, so your kitchen stays open while the work gets done.
Frequently Asked Questions
A kitchen drain cleanout is a professional service that clears grease, food, and scale from the drain pipe running off your sink. Our techs use an electric snake to scrape the horizontal pipe section clean, and we can follow up with a video inspection to confirm the line is clear all the way to the main sewer line.
In most commercial kitchens, the accessible cleanout is a capped access point on the vertical pipe or horizontal drain running from the sink to the drain stack. Some setups use a test tee for easy access to the line. If your building doesn’t have an accessible drain cleanout in place, our plumber can pull the P-trap or work through the fixture trap to reach the clog.
Yes. Grinding food doesn’t remove it; it just breaks it into smaller pieces that can still coat the sink drain. We snake the line through the drain or an outdoor cleanout, then flush with hot water to move loose debris toward the main sewer line.
Most restaurants benefit from a kitchen drain cleanout every 3 to 6 months, depending on volume. High-grease kitchens run on the shorter end. Combining regular cleanouts with grease trap service keeps wastewater flowing and helps you stay in line with your local plumbing code.
Yes. Beyond the kitchen sink, our techs clear bathroom sink lines, floor drain backups, and anything else tied into your plumbing system. If you have multiple slow drains at once, that usually points to a clog in the drain stack or main sewer line, and we will find it.
