System type: Pumped - differential control
Installed: 1995
Inspected: 2003

System is no longer operating. Collector developed a slow leak several months ago. Leak stared in approximately Jan 03. Client lived with it since leak just “dribbled a bit of water.” Client is re-roofing the house and decided to take the collector down. Does not intend to reinstall the collector. Has taken the pump, controller, and motorized check valve off. The collector was in the yard and I was able to see where the leak was. Once again, like many other flat plate collectors that failed in this program, the leak was at a riser/header connection.
