Problem With Plumbing - Advice needed!

[Citizen of Legoland]

What are the odds on this working? I filled the bath and smelled the overflow as it drained as recommended by @blueincy but it smelled normal, no foul smell at all. Would a too-shallow s-bend do this?

Mine works okay.

looks fine to me. Check the vent is installed correctly though.

What should I look out for? As you can probably tell from the rest of this thread, I have absolutely no idea what I'm doing when it comes to plumbing!

However, I am starting to doubt whether it IS the soil stack, as there is no smell in any other room. I managed to see inside the wall, and it looks as though it runs straight up, which would take it directly behind the wall at the head of our bed. Surely we'd smell anything through plasterboard?

The strange thing on the wastepipe,is a breather/air intake valve this could be faulty/stuck open,tho I have not seen one in a domestic property has the modern traps have their own little airing intake valve on them,odd that

Have you taken the boxing around the toilet off yet?

Not yet, the wife would kill me if I started dismantling the bathroom at this time. Heavily pregnant women aren't the most agreeable at the best of times!

I took this picture of the fall from the S trap. Does this look about right, or a bit shallow? I tried to get it as straight as I could, but you can kind of use the line of the wall/ floor as a guide.

should look like this, I don't know why you have a soil pipe air admittance valve inside can you not see the soil pipe outside?

If you can

this is where the valve should be on this at the top, if not and it has to be in the house under your bath looking at your pic change your U bend and your

Doesn't seem to be anything external, it's a terraced town house, and there's definitely nothing on the front or back. There's a bathroom on the top floor as well as this one (this is middle floor), and there's no problem up there. I would imagine there's an air admittance valve on the stack itself, or at least thought there should have been. I'll have to get into the attic and check to see if it's venting up there. So you think the problem may be that they haven't fitted a proper s-trap on there? Surely any competent plumber would have noticed that, rather than suggesting we knock down a few walls and fiddle with the stack itself?!

So I took the panel off the bath and took a couple of pictures of what's going on under there. Can anyone see anything out of the ordinary?

The black plastic sheeting seems to have been put in to try and keep the smell out by whichever cowboy last looked at it! No idea what the random vent is on the second image though.

The smell will only come from either the plug socket or the air admittance valve best time to smell it first thing in the morning that's how I found my bottle trap on my sink needed changing the smell of shit was unbearable..

So smell it first thing, if it's coming from the AAV, get a new one/ get rid of it, if it's coming from the plug end change the s-trap. Both of those are preferable to what we've been advised!

If there's an air admittance on the stack I don't see the need for one on the bath, take it off cover the end with your hand put plug in bath fill it half way, pull the plug out if it runs away glugging when going down (short spurts) then you need it, If it goes down normally you don't need it, cap it off end of smell..

Hope this helps PIB save your money you'll need it with a child on the way:)
