Recently had a new Grohe shower installed but noticed that after 1 week it turned to less then a trickle. Dismantled it and saw that the hot water side filter in the mixer valve was blocked with grainy white residue. Any ideas what this is and how it can be remedied. Can’t post the pic as the file size is too big. Can anyone help. Thanks
