Sewer gas smell in bathroom, advice needed

[Paul6]

Sounds like yet another "Pretty Bathroom" with absolutely no thought given as to access in time. 😡😡😡 Time to take the toilet out/ take the boxing out/ take the wall down/ access it from the other side of the wall? Whatever is needed.

Bathroom not done by me.... yes, its nicely finished and would be costly to start ripping out. Obviously if necessary we will have to but trying to go one step at a time and work out exactly what is wrong before we try fixing things. Not possible to access from other side of wall but if need be we can take tiling off and remove boxing in. Time to start looking for a local plumber I guess. Thanks for your replies.

A Smelly bog its not rocket science , check that the soil pipe it is connected to is vented correctly, if you are unable to to access the loft yourself then employ the services of a plumber , get the internals of the cistern swapped you can gain a litre or two more on the flush by having a adjustable flush valve and inlet valve fitted you may need to press and hold the button briefly , but as advised this problem will not go away a your soil pipe needs venting or if a durgo type valve is fitted then it needs to be replaced .

Just to let you know, I've had a plumber round to sort the mess, it was too big of a job to do ourselves. Annoying to start the year fixing someone else's shoddy work but needs must. Thanks for the help and suggestions.

What did they do in the end to fix it?

Yes, OP, please let us know what they find. We are interested in this kind of thing and we might even learn something from it.

We'd love it if you can come back with whatever the cause was.

Basically, there was stinking waste laying in the ridges of the connector (which was a lot longer than I thought) and due to the lack of fall, wasn't being washed away. Also I suspect, not helped by the over use of loo roll by guests over christmas. I'd tried to remove the concertina type flexible connector myself but couldn't.... it turned out the guy that fitted our bathroom had glued it in place. The plumber has cut it out completely, fitted a new 'smooth' connection and all is pleasant in the bathroom again. It will never be a brilliant flush, but it would cost well over a grand to remove the entire shower and back wall to replace the stack and horizontal waste. Now I will replace the tiled boxing in with easier to access screwed on boards.... we had said before it seemed daft that it was tiled in and they were a swine to remove.
Thanks again for your help.

Ah, but post #3. He's fixed one problem, but how was the pong getting out of a supposedly leak-tight drain into his bathroom? If it's not already been done, I'd still want to pressure test the drain.

The smell was literally coming through the flexible connector.... it was a very STRONG smell. 😱 Maybe it wasn't a very good quality connector, I don't know enough to judge but I'd be very wary of having one fitted again.

Okay, let's hope that the connector was the only issue. I'll keep my fingers crossed for you. 🙂

Been keeping an eye on this one, I'd be really pleased but also really surprised if that's it unless it wasn't properly seated. The material is specifically not smell permeable.

There could have been little holes in the top of the top of the flexi allowing the smell into the bathroom. I refurbed a customers bathroom that had an awful drain smell, the bathroom was in the middle of the bungalow with no ventilation so that didn't help matters. The problem was the flexi pan connector. Back to the wall pan so you couldn't see it but the top fins had perished forming little holes as it bent down into the floor. As the holes were on the top it wasn't causing a leak but they had lived with the smell for years 😕.

I'm really hoping I DON'T have to come back and report any more smells but will let you know if there are any developments. Thanks guys.
