Back Flow Installation And Testing

Backflow in your pipes should be continually monitored at your home in Toledo. Backflow testing is another area of expertise by Pipe Doctor Plumbing. Most areas, including Toledo, require continuous testing in a home to make sure it is safe and free from contamination.

What Is Backflow?

Basically, it is when pipes get contaminated because of broken pipes or too much pressure within the pipes. Many different problems can occur that can cause backflow to your pipes. Your pipes have a backflow prevention mechanism that should be tested regularly to keep your pipes safe.

At Pipe Doctor Plumbing, our expert technicians are certified to test and install Back Flow Check Valves in both Commercial and Residential properties. Our technicians combine their vast knowledge and the latest tools and techniques to ensure that your back flow prevention devices are operating properly.

Backflow Requirement

Water flows from the public water system into your home or business, but backflow is the “backwards flow” of water from private plumbing systems into the public water system. Backflow can carry harmful contaminants and bacteria into the public water system, which can lead to illness, injury and, in some cases, death.

Village of Whitehouse requires commercial and residential customers to install a testable backflow prevention device when their plumbing installations pose a hazard to the public water system. This device prevents water from flowing backward into the water supply.

A few examples that require backflow prevention may include:

  • Fire sprinkler systems
  • Lawn irrigation systems
  • Deduct water meters
  • Medical facilities and laboratories
  • Commercial, industrial, and manufacturing facilities
  • Multi-residential buildings
  • Restaurants
  • Hair and nail salons / spas
  • Automotive repair shops
  • Swimming pools
  • Water powered backup sump pumps

By law, Whitehouse residents must install and maintain the required backflow prevention device. Failure to do so poses a threat to the public water supply, and may result in water service being disconnected.

What is the difference between a backflow preventer and a RPZ?

A Reduced Pressure Zone (RPZ) lets you know that the valve is working properly.

RPZ backflow preventers consist of two independent check valves. They work like a double-check backflow preventer, but they also have an intermediate relief valve that opens to atmosphere if both check valves should fail.
