Backflow Prevention

It sounds like trouble just from the name doesn’t it?

Backflow occurs when there is a pressure indifference in a water supply that results in unclean water being drawn back into your supply. There are some common places in the home where this can occur, baths and showers, kitchen and laundry sinks and swimming pools.

At Lexicon we are fully licensed and equipped to install the following devices, to stop back flow from occurring:

  1. Reduced pressure zone device
  2. Check valves
  3. Double check valves
  4. Vacuum breakers
  5. A vertical Air gap
