Why does water drip from my water heater’s pressure & temperature (P&T) relief valve?

You may experience water weeping or dripping from your water heater’s pressure & temperature (P&T) relief valve when your water heater is operating. Water weeping or dripping does not mean that the P&T valve is defective. As water is heated, it expands. The water system in an RV is a closed system & does not allow for the expansion of heated water. When the pressure of the water system exceeds the relieving point of the P&T valve, the valve will relieve the excess pressure.
