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?

Where does the soil pipe terminate?

 

[Lottiejoms]

It's an internal pipe that terminates at back of house. A couple of year ago the pipe had a crack under kitchen floor and was replaced with a sleeve. I've had floor up and checked and it's bone dry

Is it vented internally (loft/bathroom) or externally thro the roof?

 

[Lottiejoms]

Through the roof

Ok, that helps rule one possibility. Rather than pulling up tiles, first, I’d be looking to make sure traps haven’t been pulled.

Checked all sink pipes traps etc and all fine, I'm going to take out shower tray and check traps and connection. If all is fine I am correct in thinking next step it to follow pipes under floor as that's the only way I will be able to get to where shower and sink connect together.

Has it always been there, or since something, eg removal of an appliance?

It's started when pipe broke under kitchen floor. At that point it was only kitchen where you could smell it. What confuses me is now pipe has been repaired the only time it smells is when the shower is used and you can smell it both in shower and in kitchen but not in bathroom on 2nd floor

It’s certainly odd that you’re unable to smell it in the 2nd floor bathroom, unless the bathroom is in a different location? I wonder if there’s an open end somewhere?

 

[Lottiejoms]

It's got me baffled. I'm now convinced it's in 3rd floor bathroom. It was not used for 2 weeks and there was no smell in kitchen. Once it was used again the smell came back and the longer you shower the worse the smell.

I would still be looking at open ends/pulled traps. My neighbour had an issue with his downstairs toilet wash basin, he complained about a draught and a slight smell, the connection to the drain wasn’t in properly (Slight open end).

Could the kitchen smell be that the sleeve is not tight enough?

Could be, certainly worth looking at.

Forgot to mention water level in toilet is low in 3rd floor bathroom only

Ahh, the plot thickens 😄 if it’s lower than the trap seal, the this would emit odours into the room.

But it's only when the showers used that it smells

So it could be the shower pulling the trap, sounds more like a partial blockage, or some form of induced siphoning.

Blockage where? Shower or soil pipe

 

[Deleted member 120897]

I would say soil pipe, depending on how the shower wastepipe runs.

 

[Lottiejoms]

It runs about 2 metres direct into soil pipethrough 2 90 degree bends

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.
