Hi, I am currently refitting our upstairs bathroom and have a question about the bath waste. I have fitted a new steel bath and have a McAlpine shallow bath trap going directly to the soil stack (approx 1.75m run). I now realise thanks to this forum that this is not acceptable as there is not a deep enough water seal in the shallow trap to feed directly into a soil stack. There is also a 32mm sink waste that is tee'd into the bath waste pipe about half way along.
So, I am wondering what my options are. As I see it I can either cut a hole in the floor boards to allow a full 'P' trap to be fitted or use a Hepvo valve instead of a water trap which will keep it above floor level.
My concern with the first option is that any leak from the bath waste connection will then drip directly onto the ceiling below rather than onto the floor boards below the bath where it can be more easily detected and sorted.
My concern with the second option is simply that I've never used one before and don't know the reliability of them.
Does anyone one have any suggestions or advice.
Thanks
