Smell in house when the toilet is flushed

[doitall]

I'm going for a blocked manhole.

well you would, wouldn`t you I reckon a frozen aav. but the OP wasn`t told to look@ the roof near the WC for a svp the lack of which would indicate an aav.

That would be my first guess as well Nige.

I am still trying to trace the location and cause of the smell. It does not seem to occur for any one item we are doing eg. sometimes smell occurs when turning on heating other time when heating is off. Sometimes when toilet is flushed other times when not. We have used dishwasher/washing machine recently but smell some days when its been used but smell somedays when not used all day.

Had a look out side and I don't have a vent on the roof like the other houses in the street. Friend of mine called it something like a stink or smell vent pipe. He guessed I must have a aav somewhere for the upstairs. I found this under the bath but again can't confirm the smell is coming from here.

shouldn`t be under the bath - should be higher Probably a dodgy system with some traps letting smells back @ random occasions . Only way is to look @ the installation . You could get pages of speculation here- then the gas fitters will start and the thread will be locked . If it was my house , I`d get that pipe outside through the wall under the bath and up above the roofline to vent . Then see what happens

Hi M Mannas,

I've read all the replies and I am sure that you are very new to this plumbing word. I think it will be better to go for a plumber now rather than inspecting by your own because you've tried everything and checked everywhere but not able to find the exact point. Call a professional and let him check the issue.

Thanks for all your help. I think I have located the aav but with my back in a brace I am unable to do much with it. I think you are right and will contact a plumber. I guess they may also advise with move the stink pipe to an external location elevated above the house.
