My T&P (temperature and pressure relief) valve is dripping water?

This is caused by either excessive incoming water pressure (40 to 70 psi is normal), or the system is a closed loop system which requires an expansion tank devise. T&P valves could at times release water due to excessive water temperature in the water heater (above 210°F/99°C). Check the aquastat setting. If this fails to correct the condition contact you local plumber or service company. Please remember that water temperatures above 120°F can cause scalding.
