When to call, and what to do first

For the problems Santa Clarita homeowners call about most, and why they come up here:

  • Water Heater Replacement

    Why it comes up in Santa Clarita: Mineral-rich groundwater in the blend builds scale in tanks, shortening their life.

    Signs:
    Water around the tank base, rusty hot water, a tank past 10 years
    Urgent when:
    The tank itself is leaking
    Before help arrives:
    Turn off gas or power and close the cold-water valve
    Repair or replace:
    Leaking tank: replace. Failed part on a younger tank: repair

    Signs:
    Warm floor spots, sound of running water, a spinning meter
    Urgent when:
    Water surfacing through the floor or a large bill jump
    Before help arrives:
    Close the main shutoff if water is visible

    Urgent when:
    Rarely urgent; scale builds slowly
    Before help arrives:
    Check your water hardness in the utility's water quality report
    Repair or replace:
    Hard water damaging heaters or fixtures: a softener protects them

Why Santa Clarita homes need these repairs

Santa Clarita is a valley of largely owner-occupied tract and planned-community homes, most built from the 1970s on, served by SCV Water. Half the supply is local groundwater and half is State Water Project water, so hardness and mineral scale show up in water heaters and fixtures, and hot summers put irrigation and slab plumbing under strain.

Santa Clarita's water supply and your plumbing

In an average year about half of SCV Water's supply is local groundwater pumped from wells, and about half is imported State Water Project water from the Sierra Nevada through the Sacramento-San Joaquin Delta. [1]

The valley's groundwater comes from the Alluvium Aquifer beneath the Santa Clara River, up to about 200 feet deep, and the Saugus Formation, up to 2,000 feet deep. [2]

Polybutylene-era homes in Santa Clarita: leaks and repiping

The median home in Santa Clarita was built in 1988, and 29% 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: 1988
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.

Santa Clarita plumbing questions

When is a leaking water heater an emergency in Santa Clarita?

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 Santa Clarita: Mineral-rich groundwater in the blend builds scale in tanks, shortening their life.

How do I know if my Santa Clarita 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 Santa Clarita: Most homes sit on slabs, and pinhole leaks in under-slab copper show up as warm floors or high bills.

Where does Santa Clarita's tap water come from?

In an average year roughly half is local groundwater from wells and half is State Water Project water imported from Northern California, delivered by SCV Water.

Why does my Santa Clarita water leave white spots on glass?

Groundwater carries dissolved minerals that dry as white spots and scale. A softener or a point-of-use filter reduces it, and flushing the water heater yearly slows tank buildup.

Do Valencia planned-community homes need different plumbing work?

Not usually, but HOA rules can limit exterior work such as moving a water heater outside or trenching across common areas, so check before a repipe or line replacement.

What should I check after a summer heat wave in Canyon Country?

Look at irrigation valves and backflow devices for leaks, and watch the water meter with every fixture off; a moving dial can point to a slab or yard leak.
