System type: Pumped - differential controller
System is working fine.
Controller tested with manufacturer’s tester and passed all functions. Sensor readings were reasonable. Pump operational.
The collector looked very good. Surprisingly, the freeze valve and air vent were in very good condition. The installer did not use the manufacturer’s collector mounting clips. Instead, a simple bracket was used to attach the standoff to the collector enclosure. Several of the screws used were not stainless and are thus starting to rust.
The exterior pipe insulation is starting to severely degrade. Some type of painted coating was used instead of metallic foil tape.
The exposed pipe runs were rather long and could easily have been plumbed inside the attic.
