    I suspect the DHW prv as the boiler plan shows the Tundish serving these valves and there is no sign of water when the heating is on and the hot water is not in use ? with the cover off its difficult to see any discharge. this made me ask can I get to these parts easily.

    one of the DHW pressure relief valves is faulty dumping water into the Tundish, pressure at 1 Bar are these acessable or is it a big job ?
