Why would water blow out of a pressure relief valve on a water pressure tank?

Water can blow out of a pressure relief valve on a water pressure tank due to excessive pressure buildup within the tank, often caused by a malfunctioning pressure switch, a failing pump, or a blocked outlet. This safety mechanism activates to prevent damage or explosion by releasing excess pressure. If the valve continuously leaks, it may indicate that the tank's air bladder is compromised or the valve itself is faulty and needs replacement. Regular maintenance can help prevent such issues.
