Who We Serve
Industries We Serve in Corona
Corona spans a wide commercial mix. Dos Lagos is the upmarket shopping and dining anchor on the southwest side, with full-service restaurants, retail, and office space. South Corona has newer master-planned commercial centers tied to its master-planned residential. The Grand Boulevard historic business strip serves established local businesses in older buildings. And North Main Street runs steady retail and dining traffic.
We also maintain plumbing for apartment communities and HOAs throughout South Corona and the central residential cores. For 24/7 dispatch see commercial emergency plumbing, and for grease and high-volume drain clearing see hydro jetting.
Compliance
Backflow Testing Requirements in Corona
California requires annual backflow assembly testing on commercial properties, and the Corona Department of Water and Power tracks compliance for Corona businesses. Restaurants, medical buildings, fire suppression lines, 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 the water department. 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 Corona Businesses
Maintenance contracts for Corona commercial properties typically include quarterly drain inspections, annual backflow testing, water heater pressure and anode checks, grease trap pump-out coordination, and scheduled hydro jetting on heavy-load lines (Dos Lagos kitchens, North Main restaurants, common-area mains).
Contract clients move to the front of the queue when emergencies hit a Dos Lagos restaurant on a weekend or a Grand Blvd business on Monday morning. You also get locked-in hourly rates, monthly consolidated invoicing, and a single point of contact familiar with your buildings.
