If you are a homeowner or business owner in Rialto, 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. Rialto is largely 1950s-1980s tract construction in the south and central neighborhoods, with newer development in North Rialto. ZIP code 92376 covers most of central and south Rialto, where we see a lot of galvanized supply line work and aging water heaters. Rialto Water Services serves much of the city, West Valley Water District serves other parts, and the water is hard, so salt-free water softener installs and water heater maintenance are common requests. The Riverside Ave corridor has a heavy warehouse and commercial presence. Commercial plumbing for those facilities is a regular part of our work.

What we see in each part of Rialto:
Newer 1990s-2010s development. Mostly water heater service and newer-home repairs.
1950s-1970s tract with aging galvanized supply lines and older water heaters.
Older mid-century homes, where sewer line repair is more common.
Hillside homes in north Rialto. Water heater work and yearly pressure regulator testing, as in every Southern California home.
Rialto was founded in 1887 by the Semi-Tropic Land and Water Company along the new Santa Fe rail line, grew as a citrus town on Lytle Creek water and a stop on Route 66 (Foothill Boulevard), and incorporated in 1911. It went from about 1,500 residents then to over 100,000 today. The housing reflects that long arc: 1950s-80s tract construction through the core, older homes near the historic Foothill/Route 66 corridor, and newer 1990s-2010s developments in north Rialto.
Water in Rialto comes through the West Valley Water District and Rialto Water Services. It's hard Inland Empire groundwater (historically fed by Lytle Creek), meaning scale and heater sediment are a fact of life here. Backflow requirements differ between the two water providers. Water pressure runs high here, as it does across Southern California, so we recommend testing your pressure regulator every year.
If you're near the Rialto Civic Center, Renaissance Marketplace or Frisbie Park, you're in our regular service area.
Our techs know Rialto well: the neighborhoods, the lot layouts and the access routes.
Rialto's housing is mostly 1950s-1980s tract construction, which comes with specific plumbing patterns we've seen for years. We arrive expecting what's typical for Rialto and ready to diagnose what isn't.
Rialto Water Services and West Valley Water District each have their own profile: we know the typical pressure range, the backflow testing schedule, and the paperwork each one requires. We test backflow devices on your provider's schedule and file the results for you.
In Rialto specifically, the most common calls we get are for aging-tract repipes in central and south Rialto and salt-free water softener installation (Rialto water is on the harder side). But the full range of work we do in Rialto includes:
Active leaks, no water, and sewer backups. Dispatched to Rialto 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 Rialto. We pinpoint the leak and keep demolition to a minimum, then repair the line or reroute it around the slab as needed.
Gas line work for Rialto homes and businesses. We pressure-test and leak-check every line before it goes back in service.
In Rialto's older homes, the sewer laterals are often cast iron or clay, with root intrusion. Camera inspection on every main line, then cable for blockages or hydrojet to clear roots and grease when the pipe is sound.
Repipes are common in Rialto's older houses, where galvanized supply lines corrode and fail. We repipe in PEX or copper, phase the work and patch any drywall we open.
Cast-iron, clay and ABS sewer lines in Rialto. Trenchless pipe bursting and pipe lining when the line allows, which can save the yard and the driveway.
Annual testing & certification for Rialto Water Services / West Valley Water District requirements. We file the paperwork directly with your water provider on your behalf. We also install and repair backflow preventers.
We serve Rialto restaurants, retail, warehouses, multi-unit, and office properties, with flexible, after-hours scheduling around your operating hours.
Sweetwater Plumbing's service area extends across San Bernardino, Riverside and eastern Los Angeles counties.
