Trusted plumber in
Loma Linda.

If you are a homeowner or business owner in Loma Linda, 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. Loma Linda is dominated by the presence of Loma Linda University and its medical center, which means commercial and institutional plumbing is a larger portion of our work here than in most cities. Multi-unit and apartment plumbing for the student and staff housing is also common. The 1960s-1990s tract homes in the rest of the city have the standard issues we see in homes of that era: pinhole leaks in aging copper supply lines, worn-out water heaters, and routine sewer maintenance.

Sweetwater Plumbing is a licensed, family-owned plumber (CSLB #889182) serving Loma Linda and the Inland Empire, rated 4.8 stars across 588+ reviews. We take urgent calls in Loma Linda 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 Loma Linda. Call (909) 312-4516 24/7.

Common plumbing issues we see in Loma Linda

Loma Linda's plumbing life is shaped by its medical and university campus as much as by its homes.

  • Around the hospital and university, the work is heavily commercial and backflow-driven: certification, code compliance, and high-use systems for offices and facilities tied to medical, lab, or food-service use.
  • In the 1960s-1990s residential tracts, aging copper supply lines and slab leaks are common as the homes age.
  • Backflow installation and testing also matter for homes with irrigation systems tied to the drinking supply.
  • Hard groundwater scales heaters across the city.

Working in Loma Linda

The Loma Linda plumbing landscape.

Housing stock

Loma Linda ("Beautiful Hill," originally "Mound City") has been a health-focused town since the Seventh-day Adventist Church founded the Loma Linda Sanitarium here in 1905, the seed of today's Loma Linda University Medical Center. The city incorporated in 1970. The housing is mostly 1960s-1990s tract construction with newer infill near the university, but much of our work here is shaped by the large medical and university campus at its center.

Water service

Most of Loma Linda is served by the City of Loma Linda. It's hard Inland Empire groundwater, so we see plenty of sediment in tank heaters and scale on valves. With a major medical campus and surrounding mix of professional and residential properties, backflow protection and code compliance matter a great deal here, especially anywhere medical, lab, or food-service use ties into the potable supply.

Gas Line Repair

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

In Loma Linda'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 Loma Linda's older housing stock, aging copper supply lines with pinhole leaks are a regular issue. We repipe with PEX or copper, work in stages, and patch any drywall we open.
