Hi All, I picked up a pair of true union ball check valves from my LFS to use for a redundant return pump setup. After I put together the plumbing and started leak testing, I discovered that the valves produce a terrible chattering noise and vibrate when under flow from a pump. The valves are identical to what CoralVue sells as "Springless Check valve", pump is Sicce SDC 6.0 and is isolated by 1ft silicone hose section. Both check valves suffer from this issue. Am I missing something?
