The GURU® Flag and Key tool works in conjunction with the anti-tampering valve’s domed cap. This tool allows you to insert the key into the cartridge end of the valve after warming the nose of the cartridge. The valve resetting stem is not accessible, eliminating the ability to leave a penny or washer tucked up under it.
