Hello All,
I wonder if anyone can help. We had an extension done 18 months ago. Ever since we have been getting vile sewer smells in the downstairs bathroom (toilet and sink). We are at our wits end;
- the builder has come back three times, fit an anti vac trap on sink as and added extra soil vent on outside wall
- there seems to be literally no pattern to when the smells come
- the sink trap is always full of water
- the toilet is also always full of water
- the upstairs is on a seperate waste system so its not coming back downstairs
- I can't see any old abandoned entry to the outside junction box to see if venting is coming through the ground but there are none
We have had two independent plumbers come and look and none of them have as clue.
We are totally at our wits end.
Can anyone tell me if there are any specialist companies or professions we can turn to?!?!?!
