Just had a plumber look at my heating/water system. In the hot water tank cupboard, behind the motorised valve, I have a pipe with a large screw on top - This acts as an air release valve. The plumber said that "automatic air release valves" are now being used to replace them. He suggests replacing the old turning screw with one of these new valves.
Anyone know anything about these?
Is this a good idea?
