I am have been renting for the past 5 years but am now having our house built.
For the past few years I have been driven mad with the foul smell coming from the bathroom drains ( this house was new when we moved in!) and despite having tried all sorts to remedy the problem I am going to admit defeat as far as this house is concerned, however I don't want a repeat of the problem in our new house, so I have been doing a little research.
I have discovered these http://www.grateseal.com.au/
They look promising and after the ongoing expense and inconvenience of trying to eliminate the foul odour we currently get most of the time I'm willing to try them out. Does anyone else have any experience of these?
