Secondly, how do you stop a water hammer check valve? Another way to prevent water hammer is to seek out a check valve with non-slam features. Non-slam check valves don’t rely on flow reversal or gravity to close. Instead, the valve is closed by a spring. As the forward velocity of the fluid slows, the spring closes the valve.
