3 way diverter valves
Posted by noel caulfield on September 02, 1999 at 16:52:26:
i am installing an open vented system & i have bought a 3 way diverter valve , the instructions that came with the valve state that under no circumstances should the valve be fitted on the return pipework , but if i install it on the cylinder flow ( dhw ) surely most of the water will pump up the open vent on the dhw flow , how can i get around this ( the valve is a honeywell v4044 )
