Why Rialto homes need these repairs

Rialto is an Inland Empire city of mostly 1950s–80s homes west of San Bernardino. Its water is mostly groundwater, with a strict zero-perchlorate policy, plus imported and surface water, and hard water, long inland summers that bake garage water heaters, and aging galvanized and copper pipe in 1950s–80s homes drive most of the plumbing calls.

Rialto's water supply and your plumbing

In 2022, 75% of Rialto's drinking water came from groundwater basins, 16% from the Baseline Feeder and 9% from surface water. [1]

Rialto has a zero-tolerance policy for detectable perchlorate; two wells have wellhead treatment that removes it to non-detect levels, and other affected wells are out of service. [2]

Polybutylene-era homes in Rialto: leaks and repiping

The median home in Rialto was built in 1982, and 43% of homes predate 1980. Homes from that era were typically built with copper or CPVC supply, plastic drains, and in some homes gray polybutylene supply pipe, which is where leaks, low pressure and drain problems usually start as they age.

Median home: 1982

  • Galvanized steel supply (1900–1960)
  • Copper supply (1950–2000)
  • Polybutylene (some homes) (1978–1996)
  • PEX / CPVC (1995–today)
Typical supply-pipe materials by construction year. Many older homes have been partly repiped since.
