Questions and Answers
As a Ridgefield homeowner, how can you help with my leaky dishwasher or corroded pipes?
While our core specialty is backflow prevention, many plumbing issues like leaks and corrosion can impact the integrity of your home's cross-connection controls. Our licensed technicians can perform a comprehensive plumbing inspection to assess the overall system. If we identify problems that could compromise your backflow device or water safety, we provide clear recommendations and can handle the necessary plumbing repair or installation to ensure everything functions correctly and meets local codes.
What does your annual backflow testing service include for my Ridgefield home?
Our annual testing is a thorough, state-compliant check of your backflow prevention device. We test its functionality, perform any necessary routine maintenance, and promptly submit the official results directly to your water supplier, such as the City of Ridgefield. We also provide convenient reminders for your next annual test. This service protects your home's drinking water and fulfills your legal requirement, all handled efficiently by our local, licensed team.
