Toilets smell of ammonia when we haven't used bleach - what is it ?
WE bought a house that needed loads of work. The upstairs toilet had a bad bleach smell that would not go away and we could not pinpoint where the smell came from. We had 3x plumbers round, none of them new what it was. We have had every pipe , toilet, sink + tile replaced in the upstairs toilet + the downstairs toilet - which is directly below the upstairs toilet (we have even replaced the floorboards in the upstairs toilet). This was all done over a month ago + now the downstairs toilet is smelling as well... we are at our wits end!! Can somebody please please help!!
