How much does a whole house water filtration system installation cost?

Pricing for a whole-house water filtration system depends on an in-home evaluation. We test your water, inspect plumbing, and size the system to your home and water issues before giving a written quote. Costs vary by contaminant levels, system type (filtration only vs. filtration + softener), and any pipe replacement needed. All work includes our one-year service warranty. Some customers report longer system warranties in reviews. Service available across the East Bay and South Bay, including Oakland and Livermore.

Quick steps:

• Schedule water testing and inspection.
• Review system options and on-site quote.
• Approve install and post-install checks.

"They even offered us a 10-year warranty on the new system, which has been working flawlessly ever since." — Brian P.
