Hi Chris and Rob
appreciate the responses...sorted now...thanks to Aqualisa and a very helpful guy called Neil (Neal?) who talked me thru.clearing the airlock by taking the head off the handset and lowering the hose in the tray.. turn on the handset..a cough and splutter then water flowed...
Help!!!
We've got a recently fitted Rise Shower + diverter valve, when we turned it on there was high pitched whine (like a pump running but with no water?). Had the guys round from Aqualisa to look it it..they advised cleared air lock.
Sure enough all good until yesterday, now...
