Plumbing in Ontario: what to know
Ontario was founded in 1882 by the Chaffey brothers as a model irrigation colony, and its historic core along Euclid Avenue still has Victorian and Craftsman homes from the late 1800s and early 1900s, along with plenty of post-war houses in the older parts of the city. In these homes, galvanized supply lines, cast iron drains and clay sewer laterals are common, often partially updated over the years.
South Ontario is the opposite. Ontario Ranch, built on former dairy and farm land, is one of the largest master-planned communities in Southern California, and its homes are new and mostly PEX-plumbed, many with tankless water heaters. The Ontario Municipal Utilities Company supplies most of the city, and the hard water here means scale builds up in water heaters and fixtures in old and new homes alike.

- Galvanized pipe and cast iron drains in older homes near downtown and Euclid Avenue.

Ontario plumbing FAQs
My Ontario Ranch home is new. Should I call the builder or a plumber?+
If the home is still under the builder's warranty, check with the builder first, since they may cover defects. For an emergency like a burst line, shut off the water and call us right away - we can stop the damage and note the cause so you have it for the warranty claim.
