Why is my electric water heater leaking water from the safety valve while the previous did not

When the water contained in the water heater is heated, it increases in volume and consequently increases the pressure inside the water heater and, more generally, in the water-sanitary system. The safety valve, which is a device that prevents excessive pressure increase, could come into operation by discharging a small amount of water to the outside, to keep the pressure within safe values. Dripping is therefore a normal phenomenon, which highlights the correct intervention of the safety valve in conditions of high pressure and which prevents potential dangerous situations for both the product and the user. In any case, to remedy the practical problems associated with the safety valve dripping, it is advisable to contact a technician.
