FAQs

A backflow prevention system stops contaminated water from reversing into your clean water supply. This can happen during pressure drops or sudden changes in the plumbing system. Without a certified assembly, harmful substances from irrigation lines, hose connections, or commercial equipment can enter your drinking water. Installing a backflow device ensures your home stays protected and compliant with local safety regulations.
Backflow assemblies in Texas require testing every year by a licensed and certified professional. Annual testing ensures the valves are functioning correctly and providing full protection against contamination. Our team keeps track of your inspection dates and sends reminders ahead of time so you never miss a required test. This helps you stay compliant with city and HOA regulations at all times.
