I have repeatedly low water pressure from my taps and shower - but only on my first floor - due to having filters blocked by some substance that is not sediment or limescale. The crystals are easily crushed and slightly waxy,slimey. I had their chemistry analysed at work. It is not sediment (e.g quartz or feldspar), it is not a metal salt (eg from corroding pipes), it is an organic material (made of C,H and O) possibly from a degrading plastic. Any ideas about what could be degrading and producing this stuff? Just to reiterate this is not limescale or sediment. Many thanks
