have water dripping from a pipe simularto a drain pipe on a washing machine?
have just cleaned my vokera combi boiler and added a proventor.Topped the system to 1.0 pressure which it as remained for a fortnight,but there is water dripping....not a lot from a large pipe with a U bend in it,in which there is a flexable pipe ....just like a washing machine.Is this something to worry about
