    An anti-siphon check valve also prevents the overfeeding that may occur due to inertial resistance. Basically, an anti-siphon check valve accomplishes this by holding the exit of the pipe with a force greater than the inertial resistance. It typically uses a spring to hold down the exit with a specific pressure.
