Backflow Prevention
A backflow prevention assembly is used to protect water supplies from contamination or pollution.
In water supply systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, etc. When pressure fails or is reduced as may happen if a water main bursts, pipes freeze or there is unexpectedly high demand on the water system, the pressure in the pipe may be reduced and may allow contaminated water from the ground, from storage or from other sources to be drawn into the system.*
Backflow Prevention was devised and implemented with security of the potable water supply and the health of citizens in mind. To maintain the safety of the water systems for homes, businesses and communities, backflow devices are required. In a home the most important one is located on the hosebibb and irrigation system. Backflow devices should be tested regularly and in most localities are required to be tested annually by a licensed professional.
Just Plumbing's team of service technicians have the training and certifications to test, repair, replace or install a new backflow device.
