Have you contacted the council?

Not yet, really don't want to have to take a whole day off just to be patronised and told they can't smell anything - but before anyone jumps down my throat, yes - I know I need to.

Thanks though :beer:

Stupid stupid me.

Last year I had totally blocked kitchen sink which the council workmen could only fix by getting into the boxed off panel in my tiny airing cupboard, but he broke the kitchen sink pipe where it goes into the soil stack, see red X on diagram below:



It was that bad they even discussed joining the kitchen sink waste pipe to the lower down bathtub waste pipe as they said it would be a nightmare to even try and repair the original soil stack pipe as it was that old and really hard to connect plastic pipes to this old (metal) soil stack pipe, but they managed to "patch it up" and bind it in loads of wet, green looking cloth that set rock hard, and conveniently re-boarded up the wood work around the pipes without letting me see it.

Soooooooooo, is there a chance this has something to do with the smell? Maybe waste water from the kitchen sink isn't fully going down the soil stack, and knowing my luck, neither is 100% of the bath water too, so maybe it's just leaking around the base of the soil stack pipe, making a smell? But the bathroom sink is on the right of the the soil stack and it's only this sinks taps that smell.

Sorry for not dropping that fact into the equation earlier, a possibility maybe... somehow?

If you cable tie didn't exit into the overflow entrance to the main drain, where did it go? Was it long enough to reach?

Well, today, after copious amounts of cheap rola-cola, soda crystals, bleach and vinegar/boiling water, I dismantled the trap and it was clean as a whistle.

Overflow seems clean too, I even poked a 12" cable tie down into the overflow hole and really poked around but nothing gunky/hairy/growing came back up and out.

What surprised me though is I expected it to go down into the overflow hole then poke out where the overflow hole meets the downpipe (before the trap bend) in the sink - but it didn't.

I am totally baffled. And what made it worse is when my other half came round, within 30 seconds of running the hot tap, she yelled "ooooh, that smell is terrible!".

Just great eh?

Thanks though and apologies for the continued suggestions.

We established what seems like months ago that the smell only comes when you run the hot tap.

If you run the hot tap with the plug out then the water from the tap goes down the plughole so possibly the passage of the hot water is stirring something up. However, when you run the hot tap with the plug in you still get the smell. With the plug in no hot water is descending into the waste system so cannot be stirring anything up but you still get the smell anyway.

If you don't run the hot tap there is no smell even with the plug out. So please tell me why everyone is faffing around telling OP to be stuffing all sorts of cleansing agents down the waste when the evidence reported by OP suggests that the waste has absolutely nothing, zilch, nada to do with the smell. The sole possible exception to this is his lightbulb recollection of earlier tonight which requires investigation but TBH I still can't see it.

You have recently determined that the trap etc and immediate adjacent waste pipework is clean as a whistle. So that cannot be the source of the smell either.

So, 4 days later I still don't think the waste is the source of the smell and I still think OP needs to get his DHW system looked at for something bacterial therein.
