Solar hot water systems require periodic valve maintenance to operate safely and efficiently. The owner at this Cooroy property reported unusual noise from the roof tank and wanted the system checked. Our technician conducted a full service including replacement of the emergency isolation valve, expansion control valve, and pressure relief valve. A new solar temperature control valve was cut in at the tank outlet, and the bathroom tempering valve was replaced. Three water-saving shower heads were fitted at the same visit. The kitchen tap confirmed hot water delivery at proper temperature. If the temperature control valve blocks again in future, full system replacement may become the practical option given the unit's age.
