I have used a check valve with a rubber stopper ball that disintegrated in one cottage season. I have gone through several brass flap style check valves, one every couple of seasons These close abruptly with a BANG and shudder. These either warp, or pit due to cavitation or something. Even though they look fine any slow loss of pressure is gone when I replace the valve.
I now use a spring loaded brass check valve. The spring slows down the closing to prevent the banging. Have had the same one for years. They are readily available at any of the big box hardware stores.
