FAQ'S
What is backflow?
Backflow happens when water flows backward through your plumbing, which can allow contaminated water to enter your clean supply. This creates serious health risks, making regular backflow testing critical for a safe and compliant system.
What does backflow installation mean?
Backflow installation is the process of setting up prevention devices, such as a residential backflow preventer, that stop polluted water from reaching your home's water supply. Our experienced team ensures proper setup that aligns with all local regulations.
What does backflow repair entail?
Backflow repair involves fixing prevention devices that are no longer functioning as intended. Timely repairs keep your system working safely and help avoid water contamination issues.
What causes backflow to occur?
Backflow generally happens due to pressure changes within your plumbing system, like a sudden loss of water pressure. These fluctuations can push contaminated water back into clean supply lines, making reliable backflow plumbing a vital part of any water system.
How often should backflow systems be inspected?
Annual backflow testing is recommended and often legally required to verify your system is operating properly. Regular inspections catch potential problems early and keep your water supply protected.
How can backflow be prevented?
Backflow prevention involves installing the right devices, like a residential backflow preventer, and maintaining a regular testing schedule to confirm everything is working as expected.
How long is the water turned off during a test?
A standard backflow test usually requires the water to be shut off for about 15 to 30 minutes. We complete the required testing quickly to keep any disruption to your day as brief as possible.
