Check valve failure is caused by issues like debris/contamination, wear and tear, improper installation (wrong direction/sizing), water hammer, material incompatibility (corrosion), and operating outside design limits (high temp/pressure). These factors lead to the valve not sealing, sticking open, or vibrating excessively, causing leaks, backflow, or blockage.
