Frequently Asked Questions
How often should I have my backflow device tested?
Backflow testing is typically required once a year to meet state and municipal regulations. Regular testing helps confirm your water system is protected and functioning properly. Our team provides thorough backflow prevention services to ensure your device meets all required standards.
What happens if my backflow device fails a test?
A failed test indicates the device is not adequately preventing contaminated or dirty water from entering your supply. This can create a serious safety concern and requires prompt attention. We repair or replace the device as needed to restore proper function and protection.
How long do backflow preventers last?
Most backflow preventers last between 10 and 15 years with proper maintenance. Lifespan can vary depending on water conditions, usage, and overall system demands. Regular service helps protect your water system and identify when replacement is needed.
Can you install a backflow preventer for new construction?
Yes, backflow preventers can be installed for new residential, commercial, or irrigation systems. Proper installation helps prevent cross connection risks and ensures your system meets all code requirements. This supports safe, reliable operation from the start.
Do you service all types of backflow devices?
Yes, a wide range of backflow devices can be serviced, including RPZ assemblies, double check valves, and pressure vacuum breakers. Each type requires specific knowledge to test, maintain, and repair properly. Our technicians are trained to handle both residential and commercial systems.
