What Is Backflow Prevention?
Backflow prevention stops water flowing in the wrong direction through a pipe, which can pull contaminated water from an irrigation system, a well or a pump back into the clean drinking supply. A backflow-prevention valve is fitted at the point where that risk exists, and tested to confirm it holds under real conditions rather than just on paper.

Valencia FAQ
What is backflow, and why does it matter?
Backflow is when water flows the wrong way through a pipe — for example, from an irrigation line or a pump system back into the clean drinking water supply, carrying contamination with it. A backflow-prevention valve stops that reverse flow.
+
When is a backflow-prevention valve required?
It's commonly required on irrigation and garden watering systems, some commercial kitchens, and any building with a private well or a pressure-boosting pump connected to the mains supply.
+
Do backflow-prevention valves need to be tested regularly?
Yes. Depending on the type of valve and its use, periodic testing confirms it's still functioning correctly — we can carry out both the initial installation and the ongoing testing.
+
Can you install a backflow valve on an existing irrigation system?
Yes. We can retrofit a backflow-prevention valve onto an existing irrigation or garden watering system without needing to redo the whole installation.
+
Is backflow prevention only relevant for commercial properties?
No. It's just as relevant for private homes with a well, a swimming pool fill line, or an irrigation system, especially if that system is connected to the same supply as your drinking water.
+
What happens during a backflow valve installation?
We identify the correct valve type for your setup, install it at the appropriate point in the system, and test it to confirm it prevents reverse flow before finishing the job.
+
Will you provide documentation after testing?
Yes. We provide written confirmation of the installation and test results, which is often needed for compliance or for a landlord, insurer or water utility.
+
Do you provide a written quote before installing a backflow valve?
Yes. Once we've confirmed the setup and the correct valve type, we give you a written quote before any work starts.
