Backflow devices are one-way valves, called check valves. They prevent the water flowing back on the other way in the pipework.

When an irrigation system is connected to the main water system, a double check valve must be used as a legal requirement, preventing the main water system from diseases. On systems installed by The Gardener’s Rain, double check valves are always installed right after the first water connection.

Operation

Check valves are maintenance-free, although there is a chance to get blocked or stuck. Replacing of them are recommended at least every 8 years.
