Your Local Plumber in Ontario
Norco Plumbing Pros extends service to Ontario, CA, the major western Inland Empire city known for downtown Ontario, the fast-growing Ontario Ranch, and the Ontario Mills area. We bring fast, dependable plumbing to its homes and busy commercial corridors.
Ontario spans historic downtown neighborhoods, established mid-century areas, and brand-new Ontario Ranch communities, plus a heavy commercial and logistics presence. We handle the full plumbing range across all of it, from older-home repairs to modern installs and commercial service.
Older downtown and mid-century Ontario homes can carry aging galvanized or cast-iron plumbing prone to leaks and sewer-line issues, while new Ontario Ranch homes need modern service and hard-water protection. We diagnose with cameras and electronic leak detection and recommend honest repairs, repipes, or trenchless sewer work as warranted.
Ontario's strong commercial base means a lot of business plumbing too — drain and grease-trap service, backflow testing, commercial water heaters, and fast emergency response that respects downtime. Across homes and businesses, the region's hard water makes softening and scale-aware service worthwhile, and we provide 24/7 dispatch with upfront pricing.

What's Wrong With Your Plumbing in Ontario?
A few quick questions to help Ontario homeowners spot the problem — and get to the right fix faster.
Is your water heater making popping or rumbling noises?
Likely cause: Hard-water sediment has settled and is cooking on the bottom of the tank.
What to do: Schedule a flush and inspection — or a replacement consult if it's far gone.
Flushing the tank yearly prevents most of this.
Water Heater RepairAre multiple drains slow or backing up at once?
Likely cause: Likely a main-line blockage or root intrusion — watch for gurgling toilets when the washer drains.
What to do: Get a camera inspection before clearing, so you fix the real cause.
Recurring backups on a treed lot usually mean roots.
Sewer Camera InspectionSee wet spots or hear water running when everything's off?
Likely cause: A slab leak, an irrigation break, or a hidden line leak.
What to do: Do the meter test, then let us pinpoint it with electronic leak detection.
If the meter moves with all water off, you have a leak.
Leak DetectionHas your water pressure dropped suddenly?
Likely cause: Often a slab leak or severe interior pipe scaling.
What to do: Get a pressure test and full-system inspection before it worsens.
Don't ignore sudden pressure loss — it rarely fixes itself.
