Why Backflow Testing Matters

Backflow occurs when water flows backward through your plumbing system, potentially contaminating the clean water supply with pollutants. This can happen due to changes in pressure caused by events like a burst pipe or increased water demand. Regular backflow testing helps prevent these situations, safeguarding your health and the community’s water supply.

San Bernardino residents are required by law to have their backflow prevention devices tested annually. This regulation ensures that all systems are up to code and operating effectively to prevent any contamination risks.

DIY Backflow Testing: Is It Feasible?

Some homeowners might consider performing their own backflow testing to save money. While this might seem like a viable option, there are several factors to consider before taking the DIY route.
