It is necessary to monitor the technical condition of the radiator and the heater tap. The radiator is checked for dents, breakages and cracks. If it is impossible to eliminate the malfunction, the radiator is replaced with a new one.
The tap may have internal valve defects caused by corrosion or wear. The tap is not disassembled, and if a defect is detected, it is replaced with a new one.
