The pressure reducing valve of the water heater does not produce water.

After the pressure relief valve of the water heater is pressed, water does not come out, which may be because the port of the pressure relief valve is blocked for a long time and does not rust. In addition, the pressure reducing valve may be damaged. You can have the water heater maintenance personnel check it, or replace the pressure reducing valve and try again.

It will not drain under the normal pressure of tap water. When the water heater is heated, the pressure generated by the internal steam expansion reaches a certain value, and the water will be discharged and released through the pressure relief valve to ensure safety.

The main function of pressure relief valve of water storage electric water heater is to avoid overheating and boiling when the temperature control circuit fails, which will lead to excessive explosion of internal pressure in the water tank. Therefore, this is not feasible under air pressure. Only when the pressure reaches a certain value will it be pushed away and leaked out.

Extended data:

The safety valve of the water heater is divided into a water inlet cavity, a water outlet cavity and a safety cavity, the safety cavity is provided with a drainage hole, a one-way valve core, an external adjusting spring and an adjusting limit piece are placed in the water outlet cavity, an elastic pad, a safety valve core, a drainage rod and a safety pressure adjusting spring are placed in the safety cavity, an adjusting cover is screwed into the safety cavity through a drainage rod, a protective cover plate is arranged outside, the end of the drainage rod is connected with a drainage lug, and a protective buckle is buckled on the drainage lug.

It has the functions of backflow prevention, safe pressure relief, drainage and cleaning, and is convenient to adjust. The safety valve should be installed vertically on the gas phase interface of the container or pipeline.
