Commercial plumbing systems operate under different load conditions, regulatory requirements, and maintenance expectations than residential systems. Fixture unit calculations for commercial installations must account for the simultaneous demand of a fully occupied building, which drives pipe sizing decisions throughout the supply and drain systems. Long Beach Pro Plumbing Inc provides commercial plumbing service, installation, and maintenance for businesses, property managers, and facilities throughout the city.
Commercial drain systems are sized using fixture unit values assigned to each drain-connected appliance under the California Plumbing Code. A three-compartment commercial sink carries more fixture units than a residential kitchen sink, a floor drain in a commercial kitchen carries additional load, and the branch drain and main drain must be sized to handle all fixtures that can reasonably operate simultaneously without surcharging the line. Undersized commercial drain systems back up under full operating load, which is why new commercial installations require plan check and inspection.
Grease interceptors are required for food service establishments in Long Beach that discharge into the municipal sewer. The interceptor must be sized to the total drainage flow rate from the kitchen in gallons per minute and must be maintained on a schedule that prevents accumulated grease from exceeding twenty-five percent of the interceptor’s liquid depth. We install, service, and certify grease interceptors and can help food service operators stay compliant with Long Beach’s pretreatment requirements.
Commercial restroom fixtures operate at far higher use cycles than residential fixtures. A flushometer valve in a busy commercial restroom may cycle hundreds of times per day. Standard residential toilet mechanisms are not appropriate for these applications. Commercial flushometer valves are rated in cycles per day and selected to match the expected use pattern. We stock parts for the major commercial flushometer brands including Sloan and Zurn and carry the tools to service them on site.
ADA compliance requirements for commercial restrooms in Long Beach specify fixture heights, grab bar placement and structural backing requirements, clearance dimensions for wheelchair access, and controls that are operable without grasping or twisting. When we retrofit or renovate commercial restrooms, we work within the current California accessibility standards and flag any existing non-compliance conditions so the property owner can address them in the scope of the project.
Multi-unit residential buildings present a combination of residential fixture types with commercial-scale shared infrastructure. Main drain stacks serving multiple floors must be sized for the aggregate fixture unit load, and venting must adequately serve all fixtures without cross-venting between units. We diagnose and repair shared plumbing systems in apartment buildings throughout Long Beach, coordinating with property managers to minimize disruption to tenants during service.
