Nasty smell in bathroom but...

[mutley racers]

I cannot find where it is coming from.

So chaps, I have a drain smell in my bathroom but cannot find where it is coming from. I have air tested all drain pipes and soil pipes but there is no leak. No man hole in bathroom, all out side. The soil pipe does run internally but on the air test it is holding. Any ideas?

Cheers chaps

is there an overflow connected to the toilet cistern, if so is it connected directly into the soil without a made up trap, otherwise I will keep thinking.

Are you farting in the bath?

No no overflow. Close coupled

Durgo or hepvo trap?

 

[Howsie]

Is the whole length of the stack holding? It could be a joint further up or down thats passing.

Flush the toilet a couple of times and see if the trap is being sucked out, if you have a shallow trap on the bath then change it for an SM10 (50mm) or similar.

Overflows on baths and sinks can get blocked up with all sorts of crap and don't smell too nice

Yep. I plugged the vent on roof and bunged the drain in man hole and all holding

There are only 2 toilets on this drain. All showers, basins and bath drop in to a drain trap outside

Time to buy a peg.

Could it be nothing to do with the drains, something has been spilt and gone off?

Might be worth getting the bleach out and giving the place a good clean

 

[oz-plumber]

Something has died under floor, in the ceiling or in a wall.

have you got the basin teed into the bath waste?

I have thought about that and infact i was under the floor yesterday looking but couldn't find any thing. I can not think of anything being spilt either . Will get the wife to give it a good scrub and see how that goes.

No, it's has its own run. All San ware does

Is anything damp/rotten? might have a leak either roof/gutter/window/waste or water leak that's slowly rotting something

I was also lookingfor these while under the floor but couldn't see any of these.

Could just be something trivial and nothing to worry about
