Downtime Is the Real Cost
A homeowner with a clogged drain is inconvenienced. A restaurant with a clogged drain is losing money every hour — and risking a health department visit. An office building with no hot water sends employees home. An apartment complex with a sewer backup has a tenant emergency on its hands.
That’s why commercial plumbing isn’t just “bigger residential.” The stakes, the codes, and the systems are different:
- Health and safety codes. Grease interceptors, backflow prevention, commercial water heater requirements, ADA fixture clearances — California’s commercial plumbing code (based on the UPC with state amendments) is strict, and inspectors enforce it.
- Scale and complexity. Multi-story drain stacks, booster pumps, recirculation systems, commercial-grade water heaters and boilers, grease waste systems. These require commercial experience, not just a bigger wrench.
- Scheduling reality. Work often has to happen overnight, early morning, or in phases — because shutting down a kitchen at lunch rush isn’t an option.

Grease: The Restaurant Killer
If you run a food-service business in California, grease is your #1 plumbing enemy — and the health department knows it. Grease interceptors (traps) are required by code, must be sized correctly, pumped on schedule, and kept in working order. When they fail, the results are dramatic: floor drains backing up during dinner service, sewer gas in the dining room, or a failed health inspection.
We install, repair, and service grease interceptors, set up pumping schedules, and — critically — we hydro jet grease lines properly. Grease doesn’t respond to a standard snake the way other clogs do; it needs high-pressure hot-water jetting to actually clear the line walls. If your “drain guy” just snakes the grease line every month, you’re paying for temporary relief. Jetting solves it.
Backflow Prevention: Required, Tested, Documented
California requires backflow prevention assemblies on commercial properties — and most water districts require annual testing by a certified tester. Miss the test, and you get the letter. Fail to comply, and you can face fines or water service issues.
Our technicians are certified backflow testers. We test, repair, and replace RP, DC, and PVB assemblies, file the paperwork with your water district, and put you on an annual schedule so you never think about it again. One less compliance headache.
Preventive Maintenance Agreements
The cheapest plumbing emergency is the one that never happens. Our commercial maintenance programs are built around your facility:
- Scheduled drain maintenance — jetting on a calendar, not on a crisis
- Water heater/boiler service — flushing, anode checks, safety controls
- Fixture audits — find the running toilets and dripping faucets wasting your water bill
- Priority response — agreement customers jump the queue, 24/7
- Single point of contact — one number, one account history, no explaining your building to a new tech every time
Property managers: ask about multi-property programs. One agreement, all your buildings, consolidated billing.
Commercial Costs — Straight Talk
Commercial work is quoted per-project — there’s no meaningful “average” across a restaurant grease line and an office TI build-out. What we promise: detailed written proposals with line-item scope, no vague allowances, change orders documented before work proceeds, and invoicing your AP department can actually process (W-9, COI, and lien releases provided as standard). We work with property managers and facility directors every day — we speak your language.
Emergency Response for Businesses
Sewer backing up into the dining room at 7 PM. No hot water in a 40-unit building. Burst pipe flooding a retail space. Commercial emergencies get priority dispatch — we understand that every hour costs you revenue, tenants, or both. Call (888) 555-0199 any time; our commercial line is answered 24/7.
Multi-Unit Residential: Apartments, Condos & HOAs
Multi-unit properties have their own plumbing personality. Shared drain stacks mean one tenant’s problem becomes everyone’s problem. Aging galvanized risers restrict flow to upper floors. Water heater banks need coordinated service so the whole building isn’t cold at once. And HOA boards need proposals they can actually approve — with clear scope, fixed pricing, and documentation.
We handle all of it: stack cleaning and descaling, riser replacements, water heater bank service and replacement, unit-turn plumbing between tenants, and main sewer lateral programs for entire complexes. For HOAs, we attend board meetings when needed, provide the photo documentation boards require, and phase large projects to spread costs across budget cycles. We currently service multi-unit properties across Southern California and the Bay Area — references available on request.
New Construction Plumbing
Ground-up commercial plumbing — from underground rough to final trim — permitted, inspected, and on schedule. We do restaurants, retail shells, office build-outs, and multi-unit residential. Our superintendents coordinate with your GC, we hit inspection milestones without drama, and our as-builts are actually accurate. If your project needs design-build plumbing or plan-and-spec work, we do both. Bonding capacity available for larger projects — ask your estimator.
What Sets Commercial Plumbers Apart
Not every plumber should touch commercial work. Here’s what to verify before hiring:
- C-36 license in good standing — verify at cslb.ca.gov. No exceptions.
- Commercial insurance levels — your lease or property manager likely requires $1M/$2M general liability. We carry it and provide COIs same-day.
- Backflow certification — required for testing in California. Ask for the cert number.
- Commercial references — residential reviews don’t transfer. Ask for commercial clients specifically.
- After-hours capability — if they can’t work nights, they can’t serve restaurants or retail properly.
We check every box. It’s why property managers stay with us for years.
Commercial Plumbing FAQs
Do you work with property managers and HOAs?
Yes — extensively. We offer multi-property maintenance agreements, consolidated billing, COIs and W-9s on file, and a single point of contact. We understand turn schedules, tenant coordination, and board approval processes.
How often should restaurant grease traps be pumped?
Most California jurisdictions require pumping when the trap reaches 25% capacity — typically every 1–3 months depending on volume. We assess your trap, set the right schedule, and handle it going forward.
Are your technicians certified for backflow testing?
Yes. Our testers are certified and we file results directly with your water district. We’ll also put you on an annual reminder so you never miss a test deadline.
Can you work overnight or on weekends to avoid disrupting business?
Absolutely. A large share of our commercial work is nights, early mornings, and weekends. We phase work so your business stays open.
Do you provide lien releases and insurance certificates?
Standard on every commercial job — COI, W-9, and conditional/final lien releases. Your AP and legal teams get what they need without chasing us.
What’s your emergency response time for commercial clients?
Agreement customers get priority dispatch 24/7. Typical emergency response in metro areas is 60–90 minutes. Call (888) 555-0199 any time.
Do you do tenant improvement (TI) plumbing?
Yes — restroom build-outs, break rooms, fixture additions, and full TI plumbing scopes. Permitted, inspected, and coordinated with your GC’s schedule.
