Why Fontana homes need these repairs
Fontana is an Inland Empire city at the foot of the San Gabriel Mountains, grown from a steel town into large tracts of stucco slab homes north of the 210 freeway and older ranch houses near downtown Sierra Avenue. Most homes are served by Fontana Water Company, which pumps from several groundwater basins and treats Lytle Creek water. Hard water, hot dry summers, Santa Ana winds and aging copper in 1950s–1980s neighborhoods drive most of the water heater, softener, slab leak and repipe calls here.

Polybutylene-era homes in Fontana: leaks and repiping
The median home in Fontana was built in 1992, and 23% 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.
- Galvanized steel supply (1900–1960)
- Copper supply (1950–2000)
- Polybutylene (some homes) (1978–1996)
- PEX / CPVC (1995–today)
Fontana plumbing questions
When is a leaking water heater an emergency in Fontana?
A leak from the tank itself won't stop and usually means replacement; turn off the gas or power and the cold-water valve, then call. Why it comes up in Fontana: Hard water and garage heat shorten tank life.
How do I know if my Fontana home has a slab leak?
Warm spots on the floor, the sound of running water with everything off and a meter that keeps moving are the usual signs; a plumber can pinpoint it before opening the floor. Why it comes up in Fontana: Most homes sit on slabs with copper under the floor.
Who supplies water in Fontana?
Most of the city is served by Fontana Water Company, a private utility; check your bill, since some edges of town are served by other agencies.
Where does Fontana Water Company get its water?
Mostly from the Chino Basin, plus the Rialto, Lytle and No Man's Land basins and treated Lytle Creek water blended with State Water Project supply.
Why do older Fontana homes need repiping?
Copper lines in 1950s–1980s ranch houses thin out from hard water and age; repeated pinhole leaks usually mean a repipe is cheaper than chasing them.
Do Santa Ana winds affect plumbing in Fontana?
Indirectly: wind-driven fires and outages can cut power to pumps and tankless heaters, so keep a shutoff key handy and know where your main valve is.
