Quick Answer
Commercial drains — especially restaurant kitchen lines — clog far faster than residential ones because of grease, food solids, and constant use. New Pro clears commercial drains and, more importantly, maintains them on a schedule so the backup never happens during business hours. Flat-rate, around your hours.
Commercial drains fail for the same physical reasons home drains do, but faster and with higher stakes. This page is part of our commercial plumbing coverage across West Los Angeles. A busy restaurant kitchen pushes more grease and food solids through its lines in a week than a home does in a year, and a backup during dinner service is not an inconvenience — it closes the kitchen. The answer is a maintenance schedule, not a phone number you call when it is already too late.
Commercial drain cleaning is the clearing and scheduled maintenance of the drain lines in a business — kitchen and floor drains, restroom lines, and the building main — to prevent the grease and solids buildup that causes operation-halting backups.
In any food-service business, grease is the number-one cause of drain failure. It cools and congeals on the pipe wall the same way it builds up in home drains, only faster and in greater volume. A grease interceptor catches much of it, but the lines downstream still scale and narrow. This is why grease-prone lines need periodic hydro jetting, which scours the wall clean rather than just punching a hole through the blockage.
The math of commercial drain maintenance is simple. A scheduled cleaning is a known, modest cost on a quiet morning. A backup during service is the cleanup, the health-code exposure, the lost covers, and the customers who leave — several times the cost, at the worst moment. We build a cleaning schedule matched to your drain load so the second scenario does not happen.
We service the full range of commercial drains: kitchen sink and prep lines, floor drains, mop sinks, and high-traffic restroom lines. Each clogs differently — grease and food in the kitchen, hair and paper in restrooms, sediment in floor drains.
For recurring trouble, we run a camera inspection to find the real cause rather than clearing the same line over and over. A recurring clog usually has a structural or grease cause worth addressing once.
Drain backing up at your business? We clear it and keep it clear.
Call (310) 663-7666We build a cleaning schedule around your drain load — monthly for a busy kitchen, quarterly for lighter use — combining cabling for routine clearing and hydro jetting for grease-heavy lines. The goal is simple: no backup during business hours.
For property managers and multi-unit buildings, we coordinate drain service across the property so one clogged stack does not affect multiple tenants. See our multi-unit plumbing page.
The Bottom Line
Commercial drains, especially restaurant kitchen lines, clog fast and close businesses. New Pro clears them and — more valuable — maintains them on a schedule that costs a fraction of a backup during service. We match the plan to your drain load and work around your hours, flat-rate.
It depends on use. A busy restaurant kitchen often needs monthly service; lighter-use office and retail drains may need only quarterly attention. We assess your drain load and build a schedule that prevents backups without over-servicing — the right interval for your business.
Grease is the main reason. Cooking grease cools and congeals on the pipe wall, narrowing the line until flow stops. Food solids add to it. Even with a grease interceptor, the downstream lines scale up, which is why grease-prone kitchen lines need periodic hydro jetting.
Cabling (snaking) punches through a blockage and restores flow quickly — good for routine clearing. Hydro jetting uses high-pressure water to scour the entire pipe wall clean, removing grease and scale buildup. For grease-heavy commercial lines, jetting resets the line to full diameter in a way cabling cannot.
Largely, yes. Most commercial backups come from predictable grease and solids buildup that a maintenance schedule catches before it stops flow. A scheduled cleaning on a quiet morning costs far less than a backup during service plus cleanup and lost revenue.
Yes. We schedule commercial drain maintenance for early mornings, evenings, or closed days so it does not disrupt service. Emergencies we handle 24/7 whenever they happen.
A drain that clogs repeatedly in one place usually has a structural cause — a belly in the line, a partial root intrusion, or heavy grease scaling. We run a camera inspection to find it, so we fix the cause once rather than clearing the symptom monthly.
