Hi, partner's daughter, who lives in Dunfermline, Fife, a soft water area, has been having a problem with the filter on the hot water input side on her shower mixer becoming clogged with what she has called "limescale". The substance is white and hard but I have not had the chance to see it for myself since a friend of hers " had a look" and removed the filter ! She has lived in the house for a year and the problem has only recently appeared. She has had a new boiler installed six months ago and it has been suggested that the fitter has reversed the polarity on "something" and this has caused a reaction which has resulted in this "crud" forming! This seems to me a bit strange and I would appreciate any assistance you can offer
