Gas Storage Hot Water System Upgrade in Castle Hill After nearly 14 years of operation, our Castle Hill clients noticed cloudy, brown-coloured water coming from their kitchen tap. MAS Plumbing Solutions attended the property and carried out a thorough inspection to identify the cause. Our diagnosis confirmed that the discoloured water was coming from the ageing gas storage hot water system. We discussed all available repair and replacement options with the clients. Considering the system’s age and condition, they decided that replacing the tank was the most reliable long-term solution. Most gas storage hot water systems carry a cylinder warranty of approximately 10–12 years, making this unit well beyond its expected warranty period. We supplied and installed the new gas storage hot water system, ensuring everything was operating safely and correctly before leaving the property. The old tank was also removed and disposed of at no additional charge. For added peace of mind, the installation is backed by the MAS Plumbing Solutions lifetime labour guarantee. If you notice rusty, cloudy or brown water coming from your hot taps, contact MAS Plumbing Solutions for a professional inspection and honest advice.
