Vacaville's water supply and your plumbing

Vacaville gets water from Lake Berryessa through the Solano Project, from the Sacramento Delta through the State Water Project's North Bay Aqueduct, and from city wells. [1]

At peak, the North Bay Regional plant produces about 51.4% of Vacaville's water, the Vacaville plant 11.9% and city wells about 36.7%; the city leans more on groundwater in dry years. [2]

Polybutylene-era homes in Vacaville: leaks and repiping

The median home in Vacaville was built in 1987, and 34% 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: 1987
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.

Vacaville plumbing questions

When is a leaking water heater an emergency in Vacaville?

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 Vacaville: Garage tanks wear out in hot inland summers.

How do I know if my Vacaville 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 Vacaville: Slab homes from the 1970s–90s develop under-floor leaks.

Where does Vacaville's water come from?

From Lake Berryessa, the State Water Project and city wells, blended at two treatment plants.

Why does Vacaville water change in dry years?

The city uses more groundwater in dry years, which is harder than the lake water.

Why do Vacaville homes get slab leaks?

Aging copper under slabs and soil movement stress pipes; leak detection finds them first.

Is Vacaville water hard?

Moderately; it gets harder when more well water is in the blend.
