System type: Pumped - differential control
No apparent problem with system.
Client claims that water heater TP valve leaked water into storage room and house. Had hose connected to TP valve drain in storage room. Tried TP valve and it operated quite well. Also shut off. Advised client to put a 5-gallon bucker under TP valve drain in the event valve was actuated in future. Also told to call plumber next time this happened.
Client’s son also claimed that water ran off the roof – continuously – from the freeze prevention valve and the air vent. Did not see any leaking during the inspection. Air vent had sediment build up at bleed outlet. Both the air vent and freeze valve will more than likely fail in due course.
Insulation was degrading. Duct tape was used as protective coating. The tape had also degraded.
