Re: pumping over
hi ya.yes hot water only thats what i thought strange. when i went to customers home to check to find boiler boxed in in cupboard with little access. i managed to check pump working ok. turned of heating selected water only then found water to be gravity fed. by the time i got to loft it was pumping over red hot and banging it head off. so had to turnoff.now removed all the boxing in that kitchen fitter had done, so it can get some air. she has messaged me tonight saying it hasn't been banging, but il have to check myself to see if its pumping over.
sunbeam .would you still say faulty stat
