I needed a new water heater. Nick was knowledgeable of the product, efficient in its installation, courteous and didn’t care that I watched the process. He alerted me to a rusted supply line elbow saving me a future leakage problem. This kind of service and attention to detail will keep me coming back to Black Diamond.
