Yesterday I removed a rad in order to remove wall paper,and then reconnected same,then topping up pressue on combi boiler,bleeding the rad etc. Later in evening noticed that there was a constant stream.trickle from the bath taps in the bathroom even when fullyclosed.There is also what appears to be a constant running/hissing noise in the pipes which are feeding the bath. The house at present is in the process of having loft converted with the inclusion of shower/ toilet facilities and as such pipework has been installed there but not yet connected to the facilities. I reduced mains pressure in attempt to resolve without success,any suggestion would be gratefully received
