Sweetwater Plumbing 💬 Text us ☎ (909) 312-4516

Trusted plumber in
San Bernardino.

If you are a homeowner or business owner in San Bernardino, 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. San Bernardino is one of the largest cities in our service area and the most diverse plumbing-wise. The historic 1880s-1920s homes downtown and on D Street regularly need full repipes: we still find lead solder and original galvanized in homes that haven't been touched. The University District around CSUSB has a heavy rental concentration, so we get a lot of multi-unit calls. Verdemont in the north is newer (1990s-2000s), and the issues there are more typical of newer tract construction.

Sweetwater Plumbing is a licensed, family-owned plumber (CSLB #889182) serving San Bernardino and the Inland Empire, rated 4.8 stars across 588+ reviews. We take urgent calls in San Bernardino 24/7, with same-day service for most non-urgent jobs booked before noon. Most of the city gets its water from the San Bernardino Municipal Water Department. Call (909) 312-4516 24/7.

Common plumbing issues we see in San Bernardino

San Bernardino is an old county-seat city with a wide range of housing, and its age is the through-line in our work.

  • Pre-1970 homes near the historic core and D Street carry galvanized and cast iron that frequently needs replacing.
  • Cast-iron and clay sewer laterals of that era crack and root up, so camera inspection is routine.
  • Postwar tracts bring slab leaks.
  • Hard Bunker Hill basin groundwater scales heaters.
  • There's also steady commercial work across the city.

Working in San Bernardino

The San Bernardino plumbing landscape.

Housing stock

San Bernardino is one of California's oldest cities, settled by Mormon pioneers in 1851 and incorporated in 1854, and as the county seat and an old railroad hub (Santa Fe, Union Pacific, Southern Pacific all ran through here) it built up early. That leaves historic 1880s-1920s homes downtown and along the D Street corridor, mid-century tract through the central city and Northpark, and newer 1990s-and-later construction up in Verdemont near the foothills. The age range is wide, and so is the plumbing we see.

Water service

Most of the city gets its water from the San Bernardino Municipal Water Department, drawing on the same Bunker Hill groundwater basin that made this a natural settlement spot in the first place. It's hard groundwater, so we see plenty of sediment in tank heaters and scale on valves. Like the rest of Southern California, San Bernardino gets high water pressure, so regulators matter.

What we fix in San Bernardino

What we fix in San Bernardino: every pipe, every fixture, every problem.

In San Bernardino specifically, the most common calls we get are for 1880s-1920s plumbing systems with lead solder, original galvanized and clay sewer laterals, and for sewer-line repair and lining work (root intrusion is a big problem in the older downtown neighborhoods). But the full range of work we do in San Bernardino includes:

Urgent Calls

Active leaks, no water, and sewer backups. Dispatched to San Bernardino 24/7.

Water Heater Service

Tank, tankless, gas, electric, hybrid. As an A.O. Smith Authorized Service Contractor, we install and service the right heater for your home.

Slab Leak Repair

Postwar San Bernardino homes can develop slab leaks where original copper passes under the foundation. We use electronic and acoustic detection and repair without tearing up floors when possible.

Gas Line Repair

We handle natural gas lines for San Bernardino properties of all kinds, with pressure testing and leak checks on every job.

Drain Cleaning & Hydrojetting

In San Bernardino'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.

Whole-Home Repipe

In San Bernardino'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.

Sewer Line Replacement

Original clay laterals are common in older San Bernardino neighborhoods. When they crack or roots get in, we line them in place or replace them. We work on cast-iron, clay, ABS and PVC lines, trenchless when possible.

Backflow Testing

Annual testing & certification for San Bernardino Municipal Water Department requirements. We file the paperwork directly with the department on your behalf. We also install and repair backflow preventers.

The company was responsive and professional. Jerry, their representative showed up on time, gave us a detailed quote and installation. I would recommend this company and this tech to others needing a water heater installed.

Matthew Perez did a good job accessing the potential problems. He snaked the drain, removed my 50 year old toilet and installed a new toilet, supply line and 1/4 angle stop. The work was accomplished professionally and to my satisfaction
