Sewage smell but Trap is fine

Anonymous user 09/03/2024 - 3.16 PM

I moved into a top floor apartment-4story building and have a sewage smell now and then. It happens usually when somebody downstairs is doing Laundry. We all have our Washers in the kitchen,connected to the sink waste water. The smell is basically bad in the sink cabinet and does Not come up from the sink itself/the trap is fine,has water in it and is clean. We also have construction on the ground floor, they are making apartments out of the shop units..unsure if it is coming up from there... At any rate the smell seems to escape from the small piece of tube before the trap? But it is waterproof. Will something simple as new washers help? Problem is it is hard to fix cause usually the dmell is not there and i can not " show" the problem and if somebody comes and repairs something,we will not know till later if the smell comes back.

Are you a tradesperson and able to answer this question?

the small piece of pipe may be an old washing machine hose to waste and is not sealed.

I've come across this alot you will need to fit a AAV which is an Air admittance Valve on the soil stack or theirs a bottle trap version you install under the sink or basin which allows air to get into the stack pipe and Preventing the sewage gasses from coming back into your property

I would add a seal to the current pipe and see if that helps before calling anybody out.

It sounds like you have a disused appliance waste connection before the trap, to test this you can take some cling film and cover the inlet. If the smell goes away then you have found the cause and need to find a more permanent solution, like having the section of pipe cut out and replaced without an appliance waste.
