hi all
i have a bad smell on downstairs loo and it is starting to drive me insane so really could do with some advice.
-i think it is like a damp/stale water smell but some believe it is sewer smell. its not particulary unbearable or anything that is why i am convinced it is not sewer. to be honest cant b convinced either way!
here are the facts:
-i have replaced toilet sink and fittings.
-i have checked the vent stack outside house and it goes past roof level with no apparent blockages
-sink trap always full of water
-its one off house on biocycle unit
only other things i can think of are these, would appreciate advice:
1.-one of the plumbers that was looking into it found a small leak on the waste pipe that connect the back of the toilet to the main plastic waste pipe out to biocyle. he relaced all of this and no leak since. however, just under where the leak was, was a hole that was never cemented/filled in. im guessing alot of water leaked down here over the months. its is a gritty silty clay-ey hole. maybe i was silly, but in an effort to rid the smell (as i convinced myself it was from this hole) i cemented over it. i thought for a while the smell got a bit better but maybe that was in my head. i also note black damp speckles on the wall near the hole. So,
-could that damp hole be the source of the smell? would concrete over it not seal it?
2. i have porous travertine tiles on the floor, could wet damp and other guck seep through these and cause a smell?they were never sealed
3. could i have a cracked sewer pipe underneath the floor. would the smell permeate through concrete? i believe a peppermint test will tell me this which i am conducting tomorrow.
any other advice wud be so appreciated!
