System type: Pumped - differential control
System is working.Checked controller out, worked fine.Client’s son was explained how system works. He is familiar with plumbing, etc.Interior
Anti scald valve stuck.
Installer should have secured feed line (coming from tank bottom - with pump) so that it was more secure – against tank.
Tank area piping insulated.
Could have secured some of the sensor wire a bit better. Some dangling.
Ceiling penetrations could have used escutcheons.Exterior
Exterior insulation wrapped with metal foil tape. Still intact.
Flashing work leaves something to be desired – aesthetics wise. But appears to be functional. Roof tar used at flashing appears to be cracking somewhat.
Sensor wire flashing pipe opening could allow rain penetration. Should have been better sealed.
