Things To Know About Backflow Preventer Installation
A backflow preventer is a vital device in plumbing systems that stops contaminated water from flowing backward into the clean water supply. Proper installation is essential to ensure safety, compliance, and effective operation. Bolton Construction & Service provides backflow preventer installation in Raleigh, Wake Forest, East Raleigh, Knightdale, Downtown Raleigh, Fuquay-Varina and surrounding regions.
- Understand Local Codes and Regulations
Before installing a backflow preventer, check with your local water authority or municipality. Many areas have strict codes and may require permits or inspections. Using an unapproved device or improper installation can lead to penalties or unsafe conditions.
- Choose the Right Type
There are several types of backflow preventers, such as Atmospheric Vacuum Breakers (AVBs), Pressure Vacuum Breakers (PVBs), Double Check Valve Assemblies (DCVAs), and Reduced Pressure Zone (RPZ) devices. The choice depends on the level of hazard and application (e.g., irrigation, fire suppression, or commercial plumbing systems).
- Proper Placement is Crucial
Install the backflow preventer at an accessible location for testing and maintenance. Some types must be installed above ground and a certain distance above flood level. Installing it too low or in a confined space can cause operational and inspection issues.
- Professional Installation Recommended
While some minor installations (like on residential irrigation systems) can be DIY, most require professional expertise. Certified plumbers ensure the device is correctly installed, tested, and complies with all regulations.
- Regular Testing and Maintenance
Most jurisdictions require annual testing by a certified technician. Backflow devices have mechanical parts that can wear out or become clogged, so regular inspection is crucial to ensure functionality.
- Protection from Freezing
In colder climates, install the device where it won’t freeze, or use insulation or heat tape to protect it. A frozen backflow preventer can crack or fail, leading to costly damage.
Installing a backflow preventer properly safeguards your water supply and keeps your system up to code.
