Why Temecula homes need these repairs

Temecula is a wine-country city of mostly owner-occupied homes built since the 1980s, with an Old Town district. Rancho California Water District blends local well water with imports, and hard water, long inland summers that bake garage water heaters, and aging copper under slab foundations drive most of the plumbing calls in town.

Temecula plumbing questions

When is a leaking water heater an emergency in Temecula?

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 Temecula: Hard blended water scales tanks.

How do I know if my Temecula 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 Temecula: Slab homes from the 1980s–2000s develop under-floor leaks.

Where does Temecula's water come from?

About 30% from local aquifers and 65% imported, blended by Rancho California Water District.

Is Temecula water hard?

Yes. Both well water and imported water carry minerals, so softeners are common.

Why does Temecula water taste different some months?
