We have a new(ish) house - it was completed 2 years ago - and we are occasionally getting a sewage smell from the airing cupboard. This cupboard houses a spiffy new MegaFlow hot water system which includes some sort of overflow pipe that has a weird fitting that has holes in it allowing you to see if the system is leaking - note it has holes and not transparent plastic - and this is where the smell is coming from. My first thought was to tape up the fitting to keep the smell at bay but I think it could be indicative of a related problem...
About 6 months after moving in we noticed the occasional sewage smell in our daughters bedroom. We eventually traced it to a vent in her built-in wardrobe which, I believe, is where one of our sewage stacks is located (her room is next to a bathroom.) The smell came and went, but could get quite bad so we eventually taped a sheet of paper over the vent to get rid of the smell. We did mention this to builders but they said that a smell through this vent was not always avoidable and that covering it would be OK as long as we made sure the toilet in the bathroom next to it was still flushing properly.
I now wonder if this original smell is related to the smell we get from the weird overflow pipe in the airing cupboard and I'm not sure what to do. There doesn't seem to be any blockage, all waste water drains fine and we have no smell coming up from the drains.
So before I tape up the fitting in the airing cupboard I thought I'd seek advice here. I am no plumbing expert but have some idea of how a DWV should work (we have two and they go into the loft and then out through the roof via some special tiles I guess.)
I wonder if the builder has fitted something incorrectly because no-one else in the street (there are 20 or so houses) is having a problem. We do have a sewer main running down the side of our house and when the weather's hot you can sometimes get a whiff.
