Frequently Asked Questions
Have questions? We’ve got answers. Here are some of the most common questions we receive from homeowners.
How long does the water testing process take?
In most cases, a quote can be provided over the phone without an on-site visit. If a technician is needed, they’ll test for hardness and TDS in about 15–30 minutes, and the customer receives the results immediately.
What areas do you service?
We serve residential customers throughout the Bay Area and East Bay Area. Contact us to confirm service availability in your specific area and get your quote today!
How often should I maintain my water filtration system?
Most systems require minimal maintenance – typically just salt refills for softeners every 4-6 weeks and filter changes annually. We offer convenient maintenance plans and will send reminders when service is due.
Does water treatment increase my water bill?
Most water treatment systems have little impact on monthly water use. Some systems, like reverse osmosis or water softeners, use additional water during operation, but the increase is usually modest and depends on household usage and system type.
