Water supply system contamination.
Water in our water supply systems is normally maintained at a specific pressure, one that allows us to have water flowing from our taps, showers, and toilets.
Occasionally, however, there is a fault. If a water pipe freezes, bursts or leaks, there is the chance that the pressure in the system can be reduced, and as a result, contaminated water from other sources can enter the system.
This can be water from the ground or from other areas where water is stored. To stop this from happening, as it can be dangerous, backflow prevention devices need to be in place.
In fact, this is a regulatory requirement for all systems. These devices
prevent drinking water from becoming contaminated.
But like car parts, they wear out over time, which is why it’s important to have them tested regularly. Certified or licensed backflow device testers can make sure that all your backflow devices are working and safe.
