It is almost time for backflow prevention testing. Often times people wonder what it is, and why they need it done each year. It is actually a shared responsibility between the community and the public utility which provides the drinking water to make sure it is free from contaminates. Each year, certified testers are responsible to comply with standards set by the utility to ensure the safety of these backflow prevention systems.
Both residential and commercial customers need backflow prevention systems on their property. Sometimes customers might have more than one system if they have an irrigation system, swimming pool, or fire sprinkler system, or if they are a medical facility.
A backflow is essentially what it says; a backward flow of water. Typically water flows from the water main into a home or commercial business. But when there is a backward flow of water from a plumbing system, going into the community source of water, it can contaminate the water. This can happen when there is a loss in pressure, when there is a vacuum type situation, or when irrigation well pumps are being primed.
Examples of potential backflow scenarios include:
- Submerging a hose in your swimming pool
- Submerging a hose in a soapy bucket to clean your car
- Submerged sprinkler heads exposed to lawn chemicals or animal feces
Backflow preventers are essentially like check valves to prevent the backwards flow of water from private homes and businesses into public water. They need to be inspected each year to ensure they are working properly.
