Hard Time Getting Air Out Of Indirect Water Heater Conveyor
My Grundfos circulator 15-42fr is making more noise than ever. Seems like my efforts to burp it have only made matters worse. One option I'm considering is adding a Spirotherm Spirotop air release valve. Please share your experience with these. Do you know if it is connected directly in the conveyor piping or if it needs a air scoop or other device under it ?
