System type: Pumped -photovoltaic control
System is working.
Pipe penetrations were resealed with roofing material. Watermark on ceiling above feed line. (Client noted water running down feed piping. Put towel at floor level to absorb drip. Has been ok since additional sealing took place.) Note that water could have penetrated from air vent valve area (between insulation and piping) and run down between pipe and pipe insulation to utility room ceiling.
