Stale smell

[Lottiejoms]

Hi all, I have a sewer type smell in my 3rd floor bathroom which transfers to my kitchen when having a shower. I've checked the connection to soil pipe and it's dry. The smell seems to bypass the second floor bathroom. Is there anything I can do or is it a case of pulling up bathroom tiles?

I believe there is a problem with your sewerage system's vent pipe. When it becomes clogged, sewer gases can back up into the sinks and toilet, causing sewage smells in your bathroom. As sewage gas forces its way into the bathroom, you may hear a bubbling sound coming from the toilet or drain. Poor installation or obstructions produced by solid objects that find their way into the vents are two possible reasons of blocked vent pipes. To remedy the problem, look for any blockages in the vent and remove them as soon as possible, then dispose of it properly. This is merely a guess on my part. Details can only be determined after inspecting the item.

Where does the soil pipe terminate?
