The reason why the solar water heater always makes strange noises at night during this time:
The cause of this breakdownis that the tap water pressure is too high. When the water tank is almost full, the floating ball floats up and down, causing the toilet door to open and close frequently. When the float valve suddenly closes, the valve core suddenly rises, causing significant vibration. Additionally, as the valve core lifts, the tap water cannot be replenished and a spatial vacuum forms, forming suction pressure, resulting in an abnormal whirring sound. product.
Solution:
Make a U-shaped loop in the water inlet pipe to increase the resistance of the pipe and the pressure will decrease, or install a pressure reducer.
