Directly south of Upland across the San Bernardino Freeway (I-10) lies Ontario, a major commercial city of approximately 175,000 residents. Founded alongside Upland in 1882 as part of George Chaffey's agricultural colony, Ontario combines historic early-20th-century residential neighborhoods near downtown Euclid Avenue, postwar residential tracts, sprawling commercial logistics hubs near Ontario International Airport, and rapidly expanding master-planned communities in Ontario Ranch. Our plumbers provide fast, reliable service for residential homeowners, apartment landlords, and commercial industrial facilities.

Historic Core Repiping vs Ontario Ranch Modern Plumbing

Ontario's plumbing infrastructure is divided between its historic north and modern south. In neighborhoods surrounding historic downtown and Chaffey High School, homes feature original galvanized water pipes and brittle clay sewer laterals that suffer from internal corrosion and tree roots. Conversely, in the newer master-planned communities of Ontario Ranch south of the 60 freeway, homes feature modern PEX plumbing and ABS drainage, where service calls focus primarily on water filtration, water heater maintenance, and fixture installations.

  • Complete PEX-a repiping for pre-1970 homes suffering from brown water and low flow
  • Whole-home water softeners to protect modern fixtures from Ontario's 200+ PPM hard water
  • Fiber-optic sewer scoping to evaluate older clay lateral condition prior to home purchases
  • Installation of commercial-grade quarter-turn fixture shutoffs during plumbing renovations
