wall mounted in garage gas boiler has started to suffer from bad water hammer on heat up really bad water surging can be detected in the flow line.
anyone any ideas, have checked and there doesn't appear to be any air in the system, pump is on the flow to a 3 port zone valve, has an auto system bypass valve fitted close to the pump. Flow to the cylinder is 15mm, heating circuit 22mm.
