valve is switching back and forth as should do (last one stopped doing this?!! had been using it on manual open setting (and wedged to stop any reset to auto).
stat is working fine and the boiler will fire up /stop according to the click on the room stat.
pump is scorching and i can hear a slight bubbley, hissing coming from it, very much like a bleeding sound (ie air escaping) but i fear it is air being sucked in......
i reckon the pump is stuffed......
possibley my fault!!! due to the air issues
off to buy a new pump will report back later
