Restaurant Plumbing in Walnut Creek, CA
Restaurant plumbing takes a different kind of expertise than a standard commercial job. RAP Plumbing keeps Walnut Creek kitchens running through inspections and the dinner rush.
Restaurant Plumbing Built Around Your Kitchen
A restaurant's plumbing system works harder than almost any other type of commercial property. Dish pits run for hours at a stretch, floor drains handle constant runoff, and gas lines feed multiple pieces of equipment at once. When any part of that system slows down or fails, it affects service, food safety, and revenue the same night.
RAP Plumbing has spent over 10 years handling commercial plumbing services for kitchens, offices, and new builds across Walnut Creek, Concord, Pleasant Hill, Alamo, San Ramon, Lafayette, Pacheco, and Martinez. Restaurant owners and managers call us for grease trap issues, gas line work, water heater capacity problems, and everything in between, because a licensed plumber who understands commercial code keeps a kitchen open instead of shutting it down.
We work around your hours, not the other way around. Whether that means an early morning appointment before prep starts or a call after close, our crew shows up ready to diagnose the problem and fix it without disrupting your service schedule any more than necessary.

What's Included in Restaurant Plumbing Service
Restaurant plumbing covers everything from routine maintenance to full system upgrades, and we scope every job to your kitchen layout and equipment.
- Grease trap and interceptor service, cleaning, and repair
- Floor drain and drain and sewer services for kitchen and dish areas
- Gas line installation and repair for ranges, ovens, and fryers
- Commercial water heater installation, repair, and replacement sized for kitchen demand
- Fixture repair for hand sinks, prep sinks, dishwashers, and mop sinks
- Pipe repair and pipe installation for aging or undersized supply and waste lines
If your restaurant is opening in a new space or renovating an existing one, we also handle tenant improvement plumbing and new construction plumbing, so grease interceptors, water lines, and gas connections are installed to code before your first service.

Built for the Demands of a Working Kitchen
Restaurants can't afford a plumbing company that treats them like a residential job. Here's what sets our commercial plumbing contractor team apart.
Licensed and Code Compliant
Our licensed plumbers know the health and building codes that govern grease traps, backflow prevention, and floor drains, so your kitchen stays ready for inspection.
Available Around Your Schedule
A slow drain or gas line problem doesn't wait for a convenient hour. Our 24 hour plumber team offers emergency plumbing services so a backed-up kitchen sink or gas leak gets handled fast, day or night.
One Plumber for the Whole Property
From dish pit fixtures to the water heater in the back office, we cover general plumbing services and office plumbing needs under one visit, so you're not coordinating multiple contractors.
How We Handle a Restaurant Plumbing Call
Every kitchen has a rhythm, and we build our process around keeping yours intact.
Step 1: Assessment and Diagnosis
We start by walking the kitchen with you, checking grease traps, floor drains, gas connections, and water heater capacity to pinpoint the actual source of the issue.
Step 2: Straightforward Pricing
Before any work begins, we explain what needs to happen and what it costs, so there are no surprises added to your invoice after the fact.
Step 3: Repair or Installation
Our crew completes the repair, drain cleaning, gas line repair, or fixture repair using commercial-grade parts rated for restaurant use and daily volume.
Step 4: Final Test and Walkthrough
We test the fix under real conditions, whether that's running water through the dish pit or firing up the range, and walk through the results with your manager before we leave.
Warning Signs Your Restaurant Needs Plumbing Repair
Small plumbing issues in a commercial kitchen tend to escalate quickly under daily use. Watch for these signs before they turn into a shutdown.
If any of these sound familiar, a sewer repair or drain repair now is almost always cheaper than an emergency call during Friday night service.
- Slow-draining floor drains or a lingering sewer smell near the kitchen
- Grease trap that needs pumping more often than usual
- Inconsistent hot water at the dish pit or hand sinks during peak hours
- Gas appliances with a weak or uneven flame
- Water pressure drops when multiple fixtures run at once
- Frequent clogs in the same drain line despite regular cleaning
Restaurant Plumbing Questions From Local Owners
Do you offer emergency plumbing services for restaurants after close?
Yes. We provide 24 hour plumber coverage for restaurants across Walnut Creek, Concord, Pleasant Hill, and the surrounding cities we serve, so a gas leak, burst pipe, or backed-up drain gets handled the same night whenever possible.
Can you install a grease trap or interceptor during a kitchen remodel?
Yes. Our tenant improvement plumbing and new construction plumbing teams install grease traps, floor drains, and water lines to meet local health code before your kitchen opens or reopens.
How often should a restaurant schedule drain cleaning?
Most kitchens benefit from drain cleaning every three to six months, depending on volume and how much grease runs through the system daily. Regular service prevents the slow drains and backups that lead to a bigger sewer repair later.
Do you handle gas line work for new kitchen equipment?
Yes. We provide gas line installation and gas line repair for ranges, fryers, ovens, and water heaters, and every job is completed by a licensed plumber to meet local gas code requirements.
