    Air lock(s) or sludge blockages?

    Why stud/pipe finders don't work?

    I have tried two different types, both Bosch, not cheap, but they gave very confusing results, so I returned them both and got my money back. I've searched this forum and it would appear that newish-build dry walled housing such as mine might have a metal foil backing on the plaster board...

    Bosch WFL 245s Softner tray not emptying
