Hello, the house was refurbished over a year ago and now we have Green crystals coming out all the hot taps in the house? The water board say it's not limescale
These green crystal like pieces are coming out of all the hot water taps and showers: we collect them from the tap filers: there are also some black pieces among them. If we take off the tap filer and put a tea strainer under the water we get the same crystals collecting in the strainer. Our hot water system is almost all plastic pipe. We first noticed a problem when, following the water mains renewal on the road, our pressure in our showers decreased: we thought they had turned the water pressure down whilst they were carrying out the works. But it very gradually got worse. They have been and tested the mains water and that is fine.
Many thanks as we are stumped and so is our plumber , thanks again
