What's actually inside your building's drain lines right now?
For most businesses, the real answer is "no idea," and that's normal. Drains are out of sight until the day a floor sink backs up during the dinner rush or a restroom starts to smell. By then, the buildup has usually been growing for months.
When it's time for drain cleaning, you'll typically hear about two options: snaking (also called cabling or rodding) and water jetting (also called hydro jetting). Both have their place. Knowing the difference helps you choose the right fix and avoid paying for the same clog twice.
Commercial drain lines take a beating that most home plumbing never sees. Depending on your business, the culprits might include:
Grease is the big one for restaurants, convenience stores, and grocery stores with prepared food. It doesn't just clog one spot. It coats the entire inside of the pipe, slowly narrowing it like a clogged artery.
A drain snake is a flexible steel cable fed into the line by a motorized machine. A cutting head on the end spins through the blockage and breaks it apart so water can flow again.
A snake punches a hole through the clog, but it doesn't clean the pipe walls. Grease, scale, and sludge stay behind, which is why the same drain often backs up again a few weeks or months later. Think of it like poking a straw through a milkshake: you've made a path, but the cup is still full.
Water jetting uses a hose with a specialized nozzle that sprays water at high pressure, both forward to break up blockages and backward to scour the pipe walls and push debris downstream. Because the water reaches the full circumference of the pipe, it removes buildup instead of just tunneling through it.
Water jetting isn't the right tool for every pipe. Lines that are already cracked, collapsed, or badly corroded can be damaged further by high pressure. That's why a good plumber will often inspect a line with a camera before jetting, especially in older buildings.
A sewer or drain camera is a small waterproof camera on a flexible cable that a plumber feeds through the line. It shows exactly what's inside the pipe and where: grease buildup, roots, sagging sections, offset joints, cracks, or foreign objects.
Camera inspections are especially useful when:
Seeing the inside of the pipe takes the guesswork out of the decision. Instead of trying one method and hoping, you can choose the right approach for the actual problem, and you'll know whether you're dealing with a cleaning issue or a pipe that needs repair.
Choose snaking if you have a sudden, isolated clog in a smaller line, or if the pipe's condition is unknown and you need flow restored quickly.
Choose water jetting if the same drain keeps clogging, if grease or scale is the problem, or if you want to clean a line thoroughly as part of a maintenance plan.
Use both in some situations. A snake might open a fully blocked line first, followed by jetting to clean the walls and prevent the clog from returning.
Most backups give you some warning first. Watch for:
Catching these signs early usually means a quicker, less expensive fix and a much lower chance of an emergency.
For restaurants and other high-use buildings, waiting for a backup is the most expensive way to maintain drains. Emergency calls tend to happen at the worst possible time, when the kitchen is full or the store is busy. A backup can mean closing a restroom, throwing out food, or even shutting down for the day.
Scheduled drain cleaning on a regular cycle keeps lines open and lets you plan the work around slow hours. How often depends on your business. A busy restaurant kitchen may benefit from water jetting every few months, while an office building might only need attention once a year or less. A plumber who knows your building can help you find the right interval.
Be wary of harsh chemical drain cleaners. They can damage older pipes and rarely remove grease buildup completely.
