    Shower valve on supply pipe

    Hi, I just bought an old house that was renovated in the 1980s. The bathroom shower has some kind of valve on the supply pipe - does anyone know what this is for? The whole bathroom will be going into a skip in a few months but I’m just curious as to what it’s for. Thanks.
