Frost damage protection
An important element of the GARDENA Pipeline System, the GARDENA Drain Valve prevents frost damage to the underground system by automatically draining when the system is not in use. The valve opens when the water pressure is under approx. 0.2 bar allowing any residual water to drain. Drain Valves should be installed at the lowest point or points of the irrigation system, and ideally installed on a bed of washed coarse gravel.
The Drain Valve is made in Germany from high-quality UV-resistant materials, and comes with a 2-year warranty.
