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

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

Thanks for that - never heard of these things before - looks like just
the thing.... (having googled)

(Only trouble is, there's now a ton of firewood stacked against the
outside wall where the shower drain exits..... and this would be the
ideal place to fit such a valve as a 'quick fix' - bother !!)

Any idea what the length of these units is ? Couldn't seem to find
a dimensioned drawing on the web...

Thanks
Adrian
