I have a warm flow combined boiler and the pipe labeled domestic cold water is leaking where it goes into a metal square box. It also has a junction on it that goes to a silver connection that the hot water goes to and the other side runs into square box as well. There is water coming out at a steady/fast rate, tried turning cold water off on pipe going to boiler but makes no difference. Would it help if I turned boiler off at wall?
