Frequently Asked Questions
What exactly is checked during a standard plumbing inspection for backflow prevention?
Our certified inspection involves a detailed check of your backflow prevention device to ensure it's functioning correctly to stop contaminated water from flowing back into the clean public supply. We test all internal seals and pressure levels, verify the assembly is installed properly, and inspect for any external damage or leaks. Following the test, we promptly submit the required certification to the local Water Authority on your behalf.
I'm in Mineola and my shrubs are dying unexpectedly. Could this be related to my backflow device or sprinkler system?
It's a common local issue we address. Dying shrubs can often point to a problem with your irrigation system. A malfunctioning backflow preventer or a leak in the sprinkler lines can lead to inconsistent water pressure or contaminated water reaching your plants. Our inspection can identify if a faulty backflow device is contributing to the problem or if there's another issue with your system's pressure and integrity, helping you protect your landscape and your water.
How often does my backflow prevention device need to be tested, and are you available on weekends?
To comply with New York State and local Water Authority regulations, backflow prevention devices must be tested annually. We understand busy schedules, which is why we operate seven days a week to provide convenient, certified testing. Since 2001, we've helped ensure both residential and commercial clients in Mineola stay compliant with these essential annual checks.
