I have 15mm Polyplumb piping in my loft and a T-piece is weeping - a washing-up bowl full every fortnight. I'm not sure if this is a long standing problem or whether it started after I put insulation on the pipes. The manufacturer's web site suggests that in order to replace them the old bits should be cut off the pipes - which would involve new sections of pipework and lots of new joints. Can anyone suggest an alternative? Phil
