Full-Service Backflow Testing, Certification & Repairs for Commercial Systems
GL Plumbing Service offers complete backflow testing, certification, repair, and new installations. We help businesses maintain code compliance and protect water supplies by ensuring their backflow prevention assemblies are tested annually, as required by local and state regulations. Whether you operate a restaurant in Glendale, manage a manufacturing plant in Brea, or run a healthcare facility in Anaheim, we handle all major types of backflow prevention devices, including double-check valve assemblies (DCVA), pressure vacuum breakers (PVB), and reduced pressure zone (RPZ) devices. If your backflow system fails inspection, we provide immediate and effective repairs using OEM parts and quality workmanship. Our plumbers are well-versed in the nuances of city-specific backflow codes and can file all necessary paperwork to ensure certification is recorded with local water departments.
