If you are a homeowner or business owner in Upland, 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. Upland's 91784 and 91786 cover two very different plumbing realities. The historic downtown (9th Street, Euclid) has homes from the early 1900s to the 1930s where we still find original galvanized supply and cast-iron drains: these almost always need attention. North of Foothill, North Upland and nearby San Antonio Heights are mostly custom homes from the 1970s-1990s. Water pressure runs high across Southern California, so pressure regulators matter in every Upland home and should be tested yearly.
Sweetwater Plumbing is a licensed, family-owned plumber (CSLB #889182) serving Upland and the Inland Empire, rated 4.8 stars across 588+ reviews. We take urgent calls in Upland 24/7, with same-day service for most non-urgent jobs booked before noon. Most of the city gets its water from the City of Upland. Call (909) 312-4516 24/7.
In Upland, from the historic homes near downtown to the foothill neighborhoods, most of our calls fall into four kinds of work.
Repair and replacement of tank and tankless water heaters. Upland’s hard water builds scale fast, and incoming pressure runs strong, so on every install we check the pressure regulator, and whenever an expansion tank goes in, we set its air charge to match your home’s water pressure first. We're an A.O. Smith Authorized Service Contractor.
Postwar tracts with supply lines under the slab are where we find most Upland slab leaks. We locate the leak with electronic and acoustic equipment, then spot repair, reroute or repipe, patch the drywall when needed, and help with the insurance paperwork.
The Craftsman-era homes around downtown and Euclid still have original galvanized pipe that’s past due. We repipe in PEX or copper and replace or add gas lines for tankless and appliance upgrades, with every gas line pressure-tested and leak-checked.
Older Upland homes often have cast-iron or clay sewer lines, and the big street trees send roots into them. We camera the line, clear roots with hydrojetting, and repair, reline or replace the line, trenchless when it fits.
Not sure what you need? Call (909) 312-4516 or text a photo to (909) 247-6791, and we’ll tell you straight.
From a slow-draining sink to a slab leak under the foundation, and from full repipes to gas line installations, we handle nearly every part of a residential or commercial plumbing system in Upland. And when something can’t wait, we offer 24/7 emergency plumbing service in Upland, too.

What we see in each part of Upland:
Custom homes from the 1970s-1990s.
Craftsman and Spanish Revival homes from the early 1900s to the 1930s. Repipes here are preservation work.
Custom homes, much like North Upland.
Newer homes, built from about 2018 on. Mostly water heater, tankless and fixture work.
Upland grew from the north end of Chaffey's Ontario colony (known first as "Magnolia," then as "North Ontario") and incorporated in 1906, and it kept the older bones to prove it. The historic district along Euclid and the downtown core holds Craftsman and other homes from the early 1900s to the 1930s, some of the oldest plumbing we touch. The foothill neighborhoods rising toward the San Gabriels carry 1970s-90s custom builds, and the flatter mid-city is a mix of mid-century tract and newer infill. Each era plumbs differently.
Upland water comes through the City of Upland, with roots in the historic San Antonio Water Company that the Chaffey colony set up in 1882; some neighborhoods are served by Cucamonga Valley Water District. The water here is hard, so scale and heater sediment are routine.

Upland has everything from early-1900s Craftsman homes downtown to recent builds, so we arrive knowing what to look for and ready to diagnose what isn't typical.
Most of Upland is served by the City of Upland, and some neighborhoods by Cucamonga Valley Water District. We test backflow devices on your provider's schedule, file the results for you and know the paperwork each one requires.
In Upland specifically, the most common calls we get are for water heaters, slab leaks, water and gas repiping, and sewer repair, plus pressure regulator failures. But the full range of work we do in Upland includes:
Active leaks, no water, and sewer backups. Dispatched to Upland 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.
Most Upland slab leaks turn up in postwar tracts with supply lines under the slab. Electronic and acoustic detection lets us repair the exact spot with minimal demolition.
For Upland gas line needs, residential or commercial, we test pressure and check for leaks on every job.
In Upland'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.
Repiping is common where Upland'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 Upland 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.
Annual testing & certification for City of Upland and Cucamonga Valley Water District requirements. We file the paperwork directly with your water provider on your behalf. We also install and repair backflow preventers.
Restaurants, retail, multi-unit and office properties in Upland. Flexible, after-hours scheduling around your operating hours.
