Commercial building water heater had a recirc. pump because of distance to fixtures. Pump plugged in but not running. How in the world would you fix this. Turn it up? :shock: :shock: :shock: :mrgreen: And check the back flow on the vent.
I would go here http://www.wattsreg.com/pdf/F-H20LS-Reprint.pdf print of plate 2 page ten and put this in with me report .
I would write in my report that the water is to hot and that you have not tested the pump as it was not running.
I would also state that it looks like there is a blow back on the water heater and recommend they get them immediatly serviced by a qualified person.

Like your print on the pictures what program are you using
Thanks Roy Cooke
Scott,
The areas you have circled look more like water stains than soot.
Just my thought.
I did a smoke test. Smoke was not going up the vent. After picture was taken I wipe some off, awful easy to get off. And I could turn the end of the pump with my finger. Took a long time to get hot water at long run fixtures also.
Thanks Roy for the chart I’ll send it with the report.
