Air vents leaking water and pipes banging
We installed a new boiler two weeks ago. The boiler is a Weil Mclain eg 45 (150000 BTus). The old one was an eg 40 (125000 Btus). We have one system. The pipes in the basement and the radiators (above the boiler 1st and 2nd floors) are banging. All the air vents in second floor are leaking water. The cut in of the pressuretrol (honeywell) is .05 and the cut off is 2 psi. Radiators are tilted towards the supply valve. Homeserve came and the guy said to skim boiler. I skimmed the boiler twice. Checked the air vents on the second floor above the boiler. The problem continues. What should I do? We did not have this problem with the old boiler.
