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.

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




Hepworth's own site certainly used to have an excellent document with
fully dimensioned drawings. But I can't find it! (Had neat drawings
showing each way in which the HepVO is superior to a conventional
trap. One was that that the trap could never dry out - by suction,
evaporation, whatever.)

Ahaaa!! Try this link - think you can get it here - have not checked
what each document is but I am sure one be have what you need.

We have three in the house. And I am considering another one...

One because it was easier and avoided problems with clearance, etc.
Two because when fitting basins into units, the ability to have a
horizontal, hidden trap or one that fits very neatly is a huge advantage.

I also used some of Hepworth's flexible waste pipe with solvent weld
ends - which was really nice to use.


Thanks - what a confusing website !
Nearest thing I could find to a dimensioned sketch of the HepVO was this
photo http://www.hepstore.co.uk/asset.aspx...&searchID=8592 - which
gives an idea of the actual size.

Problem I can see is fitting this on the 'outside end' of the waste pipe
(- I know it's an odd place to fit it but the inside section of the pipe
is embedded in concrete under the cast-in shower area). The thing is so
long that it's need some fancy right-angle bends to direct the waste
water back into the gully trap...

Maybe I'll try fitting a 90-degree bend on the end of the waste pipe -
so's the wind can't blow up the pipe so easily....? (again - this means
moving a quantity of firewood that I so carefully stacked over the
drain, only last week ! Doh!!!)

Sounds like a great invention - must file away for future reference!

Thanks
Adrian

Seems you can identify documents for download, then (if you are lucky)
use the "DOWNLOAD FOLDER" to download them all in one go. Not very nice
in reality. Find the document MMHPG.pdf and download that - page 5.
(Seeing I have been successful, I can email if you wish. Drop me an
email if you want.)

Do bear in mind, the HepVO trap can be fitted elsewhere than immediately
below the shower tray.
