  • replacing a manifold please help

    help needed urgently. i've got a combi boiler sealed system the rads are fed with 10mm micro bore from a manifold. the upstairs manifold which serve four rads started to leek and had to be replaced from a copper one to two plastic ones ever since then the rads upstairs won't get hot both the flow and return pipe are hot and so is one pipe feeding each rad off one of the manifolds the four pipes from the other manifold is cold.

            yes you need to move one manifold over and those two 22mm pipes should not be connected

              the 22mm pipes need to be connected its a sealed system flow and return.

              they where originally connected via a single copper manifold but that split after many years of service

                        They are pre-soldered fittings(solder in the ring). I don't see the point, but they are out there.
