I have a customer who I inherited this system from.
Gas fired boiler. 4 hot water baseboard zones and one radiant zone.
Each zone has a Taco sweat check on it.
The system had a zone of Heatway Onix that fouled the water quite badly.
I flushed out all the piping. Added Fernox cleaner to the system. Flushed all the residue out and then added Fernox inhibitor.
The customer has been having either no heat issues or ghost flow issues now.... if I tighten the weights down they don't open enough to let the zone circulate or if I loosen it a bit they get ghosting issues and over shooting temps.
I tried pulling apart the valve and cleaning but that's not helpful.
Any thoughts on a remedy?
