New Backflow Testing Deadline: What You Need to Know
Important Update for Cal Water Customers
If you have recently received a notice about backflow testing or you are hearing about new
requirements, you are not alone. There has been an important update, but it only applies to
certain customers.
Here is what this change means, why it matters, and how Slater Plumbing and Mechanical can
help you stay ahead of the deadline.
What Changed?
Only Cal Water has updated their backflow testing deadline.
- Cal Water customers: Testing is now due by June 15
- All other water providers: No known changes; deadlines remain the same
This is an important distinction. While many properties in Bakersfield are serviced by Cal Water,
estimated at 60 to 75 percent, not all customers are affected by this change.
If you are unsure which water provider you have, now is the time to check.
What is Backflow Testing?
Backflow testing is a process that ensures contaminated water does not reverse flow into your
clean water supply.
Without proper protection, pollutants like fertilizers, chemicals, or waste can enter your drinking
water system. Backflow devices are installed to prevent this, and testing ensures those devices
are working correctly.
This is not just a recommendation. It is a required safety measure designed to protect:
- Your drinking water
- Your home or business
- The public water system
Why Backflow Testing Matters
Backflow testing plays a critical role in maintaining water safety and regulatory compliance.
Here is why it is essential:
- Required by law: Local and state regulations mandate testing
- Prevents contamination: Keeps harmful substances out of clean water
- Avoids penalties: Missing the deadline can lead to fines or service interruptions
- Ensures system performance: Confirms your equipment is functioning properly
Who Needs Backflow Testing?
Not every property requires testing, but many do.
You may need backflow testing if your property includes:
- Irrigation or sprinkler systems
- Fire sprinkler systems
- Commercial plumbing systems
- Certain residential plumbing configurations
If you are unsure, our team at Slater Plumbing and Mechanical can quickly help determine
your requirements.
