If you are a homeowner or business owner in Fontana, 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. Fontana stretches across three ZIP codes and about 10 miles from north to south, and plumbing-wise it is essentially two different cities. Central and south Fontana (92335, 92337) are mostly 1950s-1970s tract homes: full repipes are common here because the original galvanized has reached the end of its life. North Fontana (92336) is made up of master-planned communities like Hunters Ridge and Sierra Lakes. The homes are newer, but Fontana Water Company water is hard, so salt-free water softeners and water heater anode rod service are big requests.

What we see in each part of Fontana:
2000s-2010s master-planned communities. Salt-free water softener installs are very common here.
1950s-1970s tract homes, many still on their original galvanized supply lines.
Older mid-century homes, where sewer mainline work is a common need.
Mix of older residential and the I-10 warehouse corridor where we do commercial work.
Fontana started as an early-1900s farm town (it was first called "Rosena" and took the name Fontana in 1913; the name "Fontana" means fountain or water source in Italian), then Kaiser Steel arrived in 1942 and changed everything. The mill drew thousands of workers, and the city incorporated in 1952. That left a big stock of 1940s-1970s steelworker-era tract homes in central and south Fontana, now on aging galvanized and cast iron. North Fontana is the opposite end: large 2000s-2010s master-planned communities on copper or PEX and modern drains. Today Fontana is the county's second-largest city, so we cover a lot of ground here.
Most of Fontana is served by the Fontana Water Company (a division of San Gabriel Valley Water). It's hard Inland Empire groundwater, so scale buildup and water-heater sediment are routine. Like the rest of Southern California, Fontana also gets high incoming water pressure. Knowing your provider matters for hardness and backflow requirements.

In Fontana specifically, the most common calls we get are for PEX and copper repipes in the 1950s-1970s tract homes of central and south Fontana, and for tankless water heater conversions and salt-free water softeners in North Fontana new builds. But the full range of work we do in Fontana includes:
Active leaks, no water, and sewer backups: we dispatch to Fontana 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.
Electronic and acoustic detection in Fontana. Pinpoint repairs with minimal demolition, or a reroute around the slab when that is the better fix.
We handle natural gas lines for Fontana properties of all kinds, with pressure testing and leak checks on every job.
In Fontana'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.
In Fontana's older housing stock, failing galvanized supply lines are a regular issue. We repipe with PEX or copper, work in stages, and patch any drywall we open.
We work on cast-iron, clay, ABS and PVC sewer lines in Fontana. Trenchless pipe bursting and pipe lining when the line allows, which can save the yard and the driveway.
Annual testing & certification for Fontana Water Company requirements. We file the paperwork directly with the water company on your behalf. We also install and repair backflow preventers.
From restaurants to retail to multi-unit and office buildings in Fontana, we offer flexible, after-hours scheduling.

I had to have a new water heater. When I called Sweetwater Plumbing they sent a plumber right out. Freddy Lopez was outstanding and explained everything to me. Freddy was very professional at all times. I know that if I need a plumber in the future I will be…
Freddy Lopez and Anthony were absolutely incredible. I just purchased a home that was remodeled but came across issues with one of the bathrooms. I had Roto rooter come out who couldn’t fix the issue. I found Sweetwater on Google which had great reviews…
Prompt, thorough, and knowledgeable. I also like the fact that I have had technicians return after a few years and remember me and my past projects.
