Toilet in bathroom smelling very bad even when not in use

[dean1256]

Hi,

We recently had our floor tiles done. Work was all done and plumber put everything back on including toilet but we noticed the bathroom smells very bad even when not in use especially behind the toilet, all the rooms in the house smells so we currently keep closing the door in bathroom. I have taken a picture, attached. Would someone know why this may be happening? It looks all sealed.

Thanks.

Dean

Pour some water into the black pipe, see if it drains away or fills up.

From how the photo looks, the eejit seems to have used a standard bent pan connector instead of a swanneck one. That one has made a poor joint by canting it back too far and that black pipe/collar does not look to be sealed to the soil pipe. It's really difficult to go by the photo, but it doesn't look a good job to my old eyes.

I can’t see the finned part which helps make the seal, so it could be misaligned as per @Scally-Ho, also in agreement that the wrong connection has been used.

Even when not in use
Anyway it looks like there is no seal at all where the white bit enters the balk part.
Can you see down there - or try and tip some water down - if it goes down then there is no seal. As Deluks has said

Many thanks for all your replies. I have attached another picture of what the flooring looked like before the tiles were put on. Am I correct in thinking that the black collar serves no purpose and that a pan connector should directly go into the soil pipe (that grey pipe)? The property in only 24 years old so i am assuming its a 100mm - 4 inch soil pipe?

Would the pan connector need replacing with the part below? Although it would be a big job also wondering can silicone sealant just be applied? What would be the best way to resolve this?

Pan Connectors are designed to be a snug fit in inside 110mm soil pipe, the short stub of pipe has bee fitted to achieve that. Removing it would mean fitting the Pan Connector into the 110mm socket, which is slightly wider diameter and the fins on the connector wont fit as tightly, and possibly compromise the seal. That bit looks to be right, it's more likely to be the Pan Connector that's causing you the issues. It's lost seal on the outgoing end inside the soil pipe.

Why apply something that isn’t needed?

 

[Scally-Ho]

It is difficult to assess without the measurement of the final placement of the pan spigot to the wall and the centre of the soil pipe to the wall. Those two measurements will determine what style/size of pan connector will be required.

I wasn't sure what this means. Its because of the issue described in original post. Presumably either the pan connector is going to need replacing or as one person advised me (a plumber) to put silicone sealant around it as it will be a big job removing the toilet

I was referring to the silicone sealant. Might work, might not, it's not needed. What's needed is for trades not to rush or think "ahh, it'll right, won't see or smell it from my house"
