Water Softener & Filtration in Pleasanton, CA
Ask your Pleasanton plumber for a hardness test before sizing anything — the city’s supply is Zone 7’s blend of Delta water and hard local groundwater, and grain capacity should match both the hardness and household size. Undersized softeners regenerate constantly and die young.
The honest number: $1,000–$3,500 covers most water softener & filtration work in California, with Pleasanton labor at $150–$250/hr and $90–$150 to get a truck to the door. What moves your quote inside that range is scope — which is why itemized bids beat phone estimates. For the state-wide view, see the Water Softener & Filtration cost guide.
