Pipes for vents and waste at home are not in the right position. I think it is really important to know the ‘what-and-how’ of our pipes. This is a very nice post.

Ideally your open vent should be connected to your main vent or should go as a secondary vent through the roof. If that is not possible or to expensive your vent should at least have an Air admittance valve to stop it from smelling. It is an economical solution to your problem. I hope this helps.

Smells led to me discovering an open vent under the sink near the U bend. It has no top or valve that I can see. The smell comes and goes. Is there anything I should be doing? Thankyou for all your info. I tried to give it 5 stars but it wouldn't let me! M Miles Dear Izzy,

Since there is little risk and extra cost involved in putting an AVV I would go ahead and try this solution first. Since you already have a primary vent go through your roof, a push back of smells is unlikely so the AVV only needs to help to avoid your siphons being sucked dry and diminish the risks of clogs. Just remember that if it starts smelling bad at some point, to check your AVV first, since over time they are prone to failure. As you have probably read in the article they are not optimum. A proper secondary vent is still the better solution. Are you not able to rejoin the secondary vent with the primary vent (above the highest drainage pipe off course?) If you put your secondary vent (through the roof, back to the primary or with AVV) make sure it is put after your second last siphon and not after you last siphon (which would seem a logical thing to do, but will give you problems in the long run). Water running through your last siphon will wash away any sedimentation which may have build up in the connection to the second vent. If your vent is the last one in the chain however there is no way to wash away sedimentation. This may over time clog up your second vent and stop it from doing what it should do. I hope this helps.

(You have to go through the back bedroom to access the bathroom). There is a passageway between us and our neighbours and the new en-suite will be sited above this passage. I have a builder lined up to put a new soil pipe with manhole into the existing main sewer run which runs the length of the passageway. There is no way of venting this soil pipe unless I go up through the attic and through the roof. Do you think I can use an AAV as there is already a vented soil pipe in the run at the rear of the property?

Your main vent stack will be sufficient, unless your water appliances are more than 6 meters away from your main vent stack. In that case it is recommended that you put a separate vent stack on that circuit. Put the vent stack just before your last siphon.
