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

I would consider a HepVO trap. It seals without water being present.
