If you are a homeowner or business owner in Corona, we would be glad to help and to treat your home or business like our own. We answer the phone 24/7 at (909) 312-4516. Corona has grown enormously: what was a small downtown surrounded by citrus groves is now five ZIP codes spread across north, south, and central Corona. Downtown has early-1900s homes and central Corona has 1950s-1970s tracts, where repipe and sewer mainline work is common. Sierra del Oro in the north and Eagle Glen and Dos Lagos in the south are newer master-planned communities where most calls are upgrades. Corona's water is hard, so salt-free water softeners and water heater anode service are regular requests across the city.

What we see in each part of Corona:
Newer master-planned communities. Mostly upgrades and newer-home repairs.
Mix of newer construction and older infill.
Older homes from the early 1900s. Sewer mainline and repipe work common.
Late-1980s to 2010s master-planned. Tankless conversions and salt-free water softener installs common.
Newer mixed residential and commercial. We service the retail district here.
Corona started in 1886 as "South Riverside" and was renamed in 1896 for its famous circular Grand Boulevard, the "Circle City," and later grew into the Lemon Capital of the World. That history shows in the housing: the Grand Boulevard Circle Historic District holds early-1900s homes, surrounded by 1950s-1970s central Corona, and then large late-1980s to 2010s master-planned communities like Sierra del Oro and Eagle Glen out toward the hills. Three eras, three different plumbing realities.
Most of Corona is served by the City of Corona Utilities Department, whose roots go back to the Temescal Water Company that supplied the original citrus colony in 1889. It's hard water, a blend of groundwater and imported water, so scale on heaters and fixtures is routine. Like the rest of Southern California, Corona gets high incoming water pressure, so pressure regulators matter.

Our techs know Corona well. They know Corona's neighborhoods, water provider quirks, and the common issues that come with the local housing stock.
Corona's housing covers a wide range: historic downtown, 1950s-1970s central Corona, and large late-1980s to 2010s master-planned communities in Sierra del Oro and Eagle Glen, so we arrive knowing what to look for and ready to diagnose what isn't typical.
We test backflow devices on the city's schedule and file the results with the city for you. We also know the paperwork the city requires.
In Corona specifically, the most common calls we get are for newer-construction PEX and tankless work in Sierra del Oro and Eagle Glen, and for older galvanized repipes in central Corona neighborhoods. But the full range of work we do in Corona includes:
Active leaks, no water, and sewer backups: we dispatch to Corona 24/7.
Tank, tankless, gas, electric, hybrid. As an A.O. Smith Authorized Service Contractor, we install and service the right heater for your home.
Older Corona homes can develop slab leaks where original copper passes under the foundation. Electronic and acoustic detection, and repair without tearing up floors when possible.
For Corona gas line needs, residential or commercial, we test pressure and check for leaks on every job.
In Corona's older homes, the sewer laterals are often cast iron or clay, with root intrusion. Cable for blockages, hydrojet to clear roots and grease. Camera inspection on every main line.
Repipes are common where Corona's older homes still have galvanized supply lines. We repipe in PEX or copper, phase the work and patch any drywall we open.
Original clay laterals are common in older Corona neighborhoods: when they crack or root-intrude, we line them in place or replace them. We work on cast-iron, clay, ABS and PVC lines, trenchless when possible.
Annual testing & certification for City of Corona Utilities Department requirements. We file the paperwork directly with the city on your behalf. We also install and repair backflow preventers.
For Corona's commercial properties of every kind, we provide flexible, after-hours scheduling that works around your operating hours.
Sweetwater Plumbing's service area extends across San Bernardino, Riverside and eastern Los Angeles counties.
