Noticed that water from the indirect water heater is scalding. Turned down thermostat and it still overheats way past the set temp. I can feel the heat back-feeding by touching the circulator return line from the indirect back into the boiler, its hot even when the zone valve is off and not circulating. Double checked the manual for the Boiler Mate and confirmed a check valve should be installed to prevent back-feeding. No check valve was installed...

Can you please recommend what exact check valve needs to be installed? Make and model would be great! 1" copper pipe.

Thanks!
