Why Corona homes need these repairs

Corona, the 'Circle City', has older homes near Grand Boulevard and large 1980s–2000s subdivisions climbing into the foothills. The city's utility blends desalted local groundwater with imported Colorado River and State Water Project water, so hardness, slab leaks and hillside pressure issues are common calls.

Corona's water supply and your plumbing

In 2025 about 55% of Corona's water was imported from Metropolitan Water District through Western Municipal Water District, and about 45% came from local groundwater. [1]

Most groundwater pumped in Corona goes through the Temescal Desalter, a reverse-osmosis plant that removes nitrates, PFAS, 1,2,3-TCP, perchlorate and dissolved solids. [2]

Polybutylene-era homes in Corona: leaks and repiping

The median home in Corona was built in 1990, and 24% 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: 1990
1900195020002025
  • 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.

Corona plumbing questions

When is a leaking water heater an emergency in Corona?

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 Corona: Hard imported water scales tanks in garages.

How do I know if my Corona 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 Corona: Slab subdivisions develop under-floor leaks as copper ages.

Where does Corona's water come from?

Roughly half is imported Colorado River and State Water Project water through Western Municipal Water District; the rest is local groundwater, most of it treated at the Temescal Desalter.

What does the Temescal Desalter remove?

It uses reverse osmosis to take out nitrates, PFAS, 1,2,3-TCP, perchlorate and excess dissolved solids from local groundwater.

Why is pressure so high in my Sierra del Oro home?

Foothill homes fed from reservoirs above can see high street pressure. A pressure regulator protects pipes and fixtures; replace it if pressure creeps up.

Is Corona water hard?

The imported share is hard, so scale on fixtures and in water heaters is common. Ask for a hardness test before buying a softener.
