In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Here's one. This cast iron mono-flo tee I'm guessing was installed in the mid-fifties to "try" and heat a cold porch. As I was evaluating the system for a boiler replacement I noticed them. I said to the HO " I guess this room stays pretty cold eh?" and he replied "yeh, how'd ya know that?". This was on an original open gravity system that someone recently introduced a pump to but couldn't get the house above 50.
