Backflow Testing
What is a Backflow Preventer
A backflow preventer is a system of inline checks, allowing water to pass down stream but stops water from flowing backwards, through a process of reversed flow known as back siphonage.
Why do we inspect them?
Backflow preventers are due for annual inspection and testing for a very important reason. Backflow testing helps to insure the city's water management that all precautions are taken at stopping fire sprinkler, domestic or irrigation water from finding its way backwards in to the city's water main, possibly causing a contamination issue for folks downstream.
Where are they located?
Backflow Preventers are found throughout some facilities, but most commonly are located near the road in large and small hot boxes some in pits(undergorund vault) or just take a look in mechanical rooms such the riser and water pump rooms
