Commercial Plumbing Services
Grease traps & interceptors
For any Altadena restaurant or commercial kitchen, the grease interceptor is the most regulated — and most neglected — piece of plumbing in the building. LA County requires proper sizing, regular pumping, and maintenance records. We install, repair, and service grease traps and interceptors, set up pumping schedules, and keep the documentation your health inspector wants to see. A backed-up interceptor on a Friday night is a nightmare; a maintenance plan makes it a non-event.
Drain & sewer for commercial buildings
Commercial drains take abuse that residential lines never see: food waste, paper products, cleaning chemicals, and high-volume flow. We clear commercial main lines, floor drains, and grease lines with hydro jetting — the only method that truly scours grease and scale off pipe walls — and we camera-inspect to verify the line is actually clean, not just flowing. For failed building sewers, we offer trenchless replacement that avoids tearing up parking lots.
Restrooms & fixtures
High-traffic restrooms need commercial-grade fixtures: flushometer toilets and urinals, sensor faucets, and ADA-compliant layouts. We repair and replace flush valves, rebuild faucets, unclog commercial toilets, and remodel restrooms to current accessibility and water-efficiency standards (CALGreen/Title 24).
Water heaters & hot water systems
Restaurants, salons, and medical offices can’t run out of hot water. We service and replace commercial tank and tankless water heater systems — including multi-unit banks with recirculation — sized to your peak demand and brought up to current seismic and venting code.
Backflow prevention
Commercial properties in LA County are required to have tested backflow prevention assemblies protecting the potable water supply. We install, repair, and annually test reduced-pressure (RP), double-check (DC), and pressure-vacuum-breaker (PVB) assemblies, and file the test reports with the water authority.
Gas lines
Commercial kitchens run on gas — ranges, fryers, water heaters, and HVAC. Our gas line services cover new runs, upsizing for added equipment, earthquake valves, and permitted pressure testing.
Code Compliance & Inspections
Commercial plumbing lives under a microscope: health inspectors, fire marshals, building inspectors, and water authorities all have jurisdiction. We build compliance into every job:
- Permitted work, inspected and signed off. We pull LA County/City permits for commercial work and meet inspectors on site.
- Health department readiness. For food service: proper air gaps, grease interceptor sizing and maintenance logs, hand-sink requirements, and mop-sink installations.
- ADA & Title 24. Restroom remodels meet accessibility clearances and California water-efficiency fixture standards.
- Documentation. Invoices with license numbers, test reports, and maintenance logs — the paperwork property managers and franchise compliance teams need.
Preventive Maintenance Plans
The cheapest commercial plumbing emergency is the one that never happens. Our maintenance plans are built around your building type and usage:
What’s included
- Scheduled drain line cleaning and hydro jetting on a set interval
- Grease trap/interceptor pumping coordination and service
- Water heater flushing, anode checks, and efficiency testing
- Fixture audits: flushometers, faucets, and shut-off valves tested and adjusted
- Backflow assembly annual testing and filing
- Priority emergency dispatch and discounted rates for plan members
Plans are quoted per property after a walkthrough — no generic packages that don’t fit your building. Most clients recover the cost in avoided emergencies within the first year.
