Relief System

Relief System
my pressure relief valve is discharging . my heating system is brand new it was installed saturday what should

i have two zones (1) is cast iron radiators and the other is hydronic baseboard. Iset the fill valve to 12psi cold but it is still blowing

Just call the man, Aunt Bee!! Really, if the system is only two days old you should call the people you bought it from and have them come and check it out.
