Frequently Asked Questions
How often should I have my well serviced in California?
Most state environmental agencies recommend annual well water testing and periodic system inspections. Given documented groundwater contamination issues in some areas, annual testing is especially important. Have the system mechanically inspected every 3-5 years.
What does routine well maintenance include?
A routine well maintenance visit includes visual inspection of the well cap and casing, checking the pressure tank and switch, testing water pressure and flow rate, inspecting electrical connections, and collecting a water sample for testing.
How do I find a reliable well service company in California?
Look for companies licensed by the **California Board for Professional Engineers, Land Surveyors, and Geologists (BPELSG)** for engineering/geology work, or holding a **C-57 Well Drilling Contractor** license (CSLB) for well drilling. Verify they carry liability insurance and have experience with your type of well and local geology. Your **county Environmental Health** office can explain local lists and permit requirements.
