Backflow Service

Backflow is the term used to describe the phenomenon of water flowing backward through your plumbing system.  This is usually caused by a sudden and drastic change in pressure pushing the water backward (backpressure) or pulling it back into the main supply (backsiphonage). This not only can cause your building to suddenly and unexpectedly lose your water connection, but could potentially risk contaminating your potable water supply, or worse, the main water supply line that your building is connected to.

This is why all commercial buildings are required to have backflow prevention devices. And all backflow devices are required to be tested on an annual basis.

Whatever type of backflow prevention device services you need, the experts from Raymar Plumbing Services can help you get it done.

Some examples of systems which can cause backflow contamination include:

  • Irrigation systems (lawn sprinklers, drip systems, etc.)
  • Fire sprinklers
  • Water treatment systems
  • Sewage treatment systems
