Why is backflow preventer important?
A well-built irrigation system is crucial for cultivating plants in landscapes, but it’s just as important for a homeowner’s health.

What are backflow preventers?
Backflow preventers are designed to prevent this adverse scenario. Since landscape contains water with all sorts of toxic substances that can bring about sicknesses or worse, mixing that supply with potable water needs to be avoided at all costs.

If a household is connected to a municipal water system, these toxic substances can make their way to the pipeline and taint the water supply.
