System type: Pumped - photovoltaic control
Installed: 1996
Inspected: 2003

System is not working.

Pump does not appear to be working. No vibration or sound of any type - during full sun period. Checked wire clips. Somewhat loose but still sufficient contact. PV module is fine. PV wire voltage test acceptable.

Checked feed and return pipe temperatures. No pump activity even in full sun.

Pressure relief valve on roof is leaking. Constant drip. Tried closing to no avail. Water pooling at roof location.

Air vent has scale buildup from previous activity. Not leaking. Roofing material in pitch pans is drying and creating cracks and pools. Isolated the system.
