HI Folks
Finally traced the source of the nasty 'sewage' smell in our ground-floor shower room.
It's got one of those nasty 'wet-room' type showers - a 6" tiled upstand across the width of the room and a 'not-slopey-enough' tiled area with a shower trap set in the floor.
The water trap is ever so shallow (accessed by removing the grille over the trap) and, as the shower isn't used all that frequently, and the water evaporates, the nasty smells from the drain outside find their way up the waste pipe and into the room. Problem solved at the moment by stuffing a cork into the drain-pipe - but that's a bit inconvenient (apparently)
So - what to do about it ?
I've not fitted a shower tray for a while - don;t know what the current 'traps' look like. Thinking of planting a complete new tray on top of the 6" upstand to allow a proper trap to be fitted under the tray and pipe it though a new hole to the drain outside.
Any other possibilities or suggestions please ?
Thanks Adrian
