Fast, thorough drain and sewer line cleaning for restaurants, commercial kitchens, and facilities across Southern California — from high-pressure hydro jetting to rooter service, camera inspection, and preventive maintenance that keeps you draining and open for business.
A clogged drain in a commercial kitchen isn't an inconvenience — it's lost revenue, a failed health inspection waiting to happen, and water where it shouldn't be. JN Grease Service clears and maintains commercial drain and sewer lines so grease, food waste, and buildup never shut you down.
With more than 25 years serving Southern California's restaurants and facilities, we don't just punch through a clog — we clean the line wall to wall, verify the result with a camera, and help you stay ahead of the next backup with a maintenance plan built around how you operate.

Commercial drain cleaning is the professional clearing and maintenance of the drain, waste, and sewer lines that carry water and waste out of a business. In restaurants and commercial kitchens, those lines take a constant load of grease, food particles, soap, and debris that gradually coat the inside of the pipe, narrow the flow, and eventually cause slow drains and full backups. Unlike a quick home-store drain product, commercial drain cleaning uses professional equipment — high-pressure water jetters, motorized cable machines, and sewer cameras — to actually remove the buildup and restore the line to its full diameter. The goal isn't just to get water moving again; it's to clean the pipe thoroughly, confirm the result, and prevent the problem from coming back in the middle of your busiest service.
Every blockage is a little different, so we match the method to the pipe and the problem. Hydro jetting uses high-pressure water — up to around 3,500 psi — to scour grease, sludge, scale, and roots off the pipe walls, and it's the most thorough option for grease-heavy commercial lines. Cable snaking (rooter service) uses a rotating cable to break through a localized clog quickly, which is ideal for fast relief and for lines with root intrusion or a single obstruction. Camera inspection lets us see exactly what's happening inside the line — locating the blockage, checking the pipe's condition, and verifying the line is truly clear after we clean it. Combined with grease trap and interceptor service, these methods address both the symptom and the source, because a clean drain line doesn't stay clean if grease keeps pouring in upstream.
Reliable drains do more than move water — they protect your revenue, your reputation, and your health score. A single backup during service can close a dining room, damage flooring and equipment, and put you out of compliance in minutes. Professional drain cleaning keeps fixtures, floor drains, and sewer lines flowing efficiently, reduces the odors that come from stagnant buildup, and catches weak spots before they become emergencies. Businesses that invest in regular, professional drain maintenance spend far less on emergency repairs, lose less time to downtime, and keep a cleaner, safer environment for both staff and customers. Our technicians bring the right equipment, training, and experience to handle anything from a slow floor drain to a fully blocked main line.
Knowing when to clean your drains is the difference between a scheduled visit and a 9 p.m. emergency. Call for service when drains are running slow, when clogs keep coming back soon after being cleared, when you notice gurgling or rising water, or when odors start creeping up from floor drains. For commercial kitchens, the smartest approach is preventive: routine hydro jetting on a quarterly or semi-annual schedule removes grease before it hardens into a blockage and keeps your lines flowing year-round. Regular camera inspections identify problems early, extend the life of your plumbing, and keep your costs predictable instead of catastrophic. Staying proactive means your drains are one less thing to worry about during a rush.

Both clear a clog — but only one cleans the pipe. Here's how they compare so you can choose the right fix.
Quick Fix · Temporary
A rotating cable bores a hole through the blockage. It restores flow fast, but leaves the grease and buildup coating the pipe walls.
Deep Clean · Long-Lasting
High-pressure water scours the pipe wall to wall, flushing out grease, sludge, and roots and restoring the line to full diameter.
Professional drain cleaning sounds aggressive, but in trained hands it's safe for healthy commercial pipes — and far gentler on your operation than repeat backups. We inspect first, match the method and pressure to your line, and verify the result.

Drain cleaning is priced around the line and the buildup. Here's what we factor into your quote.
Larger and longer lines take more time and water to clean fully.
Heavy grease, scale, or root intrusion is a bigger job than a light clog.
Easy cleanout access is faster than hard-to-reach or buried lines.
Inspection and verification ensure the job is done right the first time.
Emergency and after-hours service is dispatched on priority.
Routine cleaning prevents emergencies and keeps costs predictable.
Grease-heavy lines, floor drains, and interceptors kept clear and inspection-ready.
Cafeterias, catering kitchens, and food processors with high-volume drains.
Malls, offices, and multi-tenant buildings with shared sewer and drain lines.
Based in Menifee, we serve Riverside, San Bernardino, Los Angeles, and Orange counties — and the surrounding communities.
Commercial drain cleaning is the professional clearing and maintenance of the drain and sewer lines in a business. For restaurants and facilities it includes hydro jetting, cable snaking (rooter), grease line clearing, camera inspection, and scheduled preventive maintenance to keep lines flowing and prevent backups.
Snaking punches a hole through a clog to restore flow quickly but leaves buildup on the pipe walls, so clogs often return. Hydro jetting uses high-pressure water to scour the pipe wall to wall — removing grease, sludge, scale, and roots — so results last much longer.
Most grease-heavy kitchens benefit from professional drain cleaning on a quarterly or semi-annual schedule, with high-volume operations sometimes needing it more often. Routine jetting removes grease before it hardens into a blockage and helps you avoid emergency backups during service.
Yes. We offer 24/7 emergency drain cleaning across Southern California. If your lines back up during service, call (951) 343-1221 and we'll dispatch a crew to clear the blockage and get you draining again.
Yes, when performed by professionals. We camera-inspect the line first and match the water pressure to your pipe size, material, and condition, so jetting safely clears buildup that snaking can't reach without harming healthy commercial pipes.
