Who We Serve
Industries We Serve in Fontana
Fontana’s commercial scene is split — the dining and retail strips along Sierra Avenue and Foothill Boulevard, the event-driven food and hospitality demand around Auto Club Speedway, and one of the densest warehouse/distribution corridors in Southern California south of the I-10. We service all three. Restaurants get grease line jetting and ADA fixture work, warehouses get high-flow restroom maintenance and process-water connections, and event venues get pre-event inspections and surge support.
We also maintain plumbing for apartment communities and HOAs across central and north Fontana. For 24/7 dispatch see commercial emergency plumbing, and for grease and warehouse drain clearing see hydro jetting.
Compliance
Backflow Testing Requirements in Fontana
California requires annual backflow assembly testing on commercial properties, and Fontana Water Company tracks compliance for Fontana businesses. Restaurants, medical buildings, fire suppression lines on warehouses, and irrigation backflows on HOA properties are typical test points.
We are certified backflow testers — we test, document, repair or replace failed assemblies, and submit paperwork directly to Fontana Water Company. If you also have a sewer line or gas line issue, we roll those into the same visit.
Stay Ahead of Failures
Preventive Maintenance Programs for Fontana Businesses
Maintenance contracts for Fontana commercial properties typically include quarterly drain inspections, annual backflow testing, water heater pressure and anode checks, grease trap pump-out coordination, warehouse restroom and process-water inspections, and scheduled hydro jetting on heavy-load lines.
Contract clients move to the front of the queue when emergencies hit — a Sierra Ave restaurant on Friday night or a warehouse main break Monday morning. You also get locked-in hourly rates, monthly consolidated invoicing, and a single point of contact familiar with your buildings.
