Indeed, but my particular fridge gives me under 1cm space to access it and does not come away. Youtube videos suggest unclipping it and pulling strongly as there is glue holding it, but it's flimsy (by Beko) and I fear it might break which will be an even bigger pain!
I found the cause!!!
Seems to be the fridge back evaporation tray
Originally thrown by it as did not smell when I last checked
Either an animal climbed into it and died (unlikely) or the condensed water was contaminated with food/milk that now sits inside the tray and might smell worse when...
Although I don't like the idea of finding them, I am hoping it is something like this. But from what I have read, the rotting eventually stops and so the smell, perhaps after 2 weeks, and it has been going on for longer and is intermittent....
If the smell is different from fresh gas, is there a way the added mercaptan smell can be altered before it escapes (partially burnt off, for example) if there is a gas leak?
It's tiled over solid/concrete floor so no place for an animal to be deeper down but there could be a crack in a soil pipe or similar that I have not seen letting the smell out at peak times
Should have said, I am in a flat with the kitchen facing out into a balcony. All pipes are either visible within the kitchen for inspection or outside it.
Check under every cabinet and in very corner for dead animals. Floor has been bleached cleaned. It's coming from one corner of the room where there is an undercounter fridge with the gas stove to the left of it and boiler to the right of it. Back of fridge does not smell of leaking compressor...
It has all been siliconed and cemented right up to the connection to the basin, so as @blup said I'll probably just fit a P trap after creating an appropriate connection coming from the wall.
Cowboy builders left me with this. Doesn't leak anymore, but there should be a trap/u-bend right? Apart from the smells coming from the plug-hole are there any issues that I may face?
1) door being fitted in order to keep it accessible at all times
2/3) already had ofgem comment on it and they wont move the meter as there nothing wrong with how it is. the shut off should be drop down by regs but even that they wont fix!
Shift it right, right? Then the cupboard door I mentioned can cover the area top to bottom. I am looking feedback for the covering whole area, not just move something around.
