    Floating ball valves leaking at low pressure

    I'm trouble shooting an instesting problum. Numerious 3" 300# ball valves (floating design) hold fine at high pressure (600 psi) but leak at low pressure (aprox 15psi head pressure) when pumps are off.Water service on pump discharge. Is this a common trait for floating ball valves?
