Kitchen sink wouldn't drain, which I traced to the external drain being completely blocked with fat by the previous owner (I’ve only been here a few months). Honestly, it was like one of those sewer documentaries which have been on telly lately – I removed about a stone of stinking fat from the drain, as far as I could reach, and now it drains really well.
However… I don’t understand what’s going on down there. Looking at the picture, the drain out of the sink is at the top; the fat-blocked exit is to the right. But what’s that to the left? It seems to be another drain, with a circular inspection hole, with a round rubber cover (which wasn’t attached).
What’s that for please? Can’t get the !@*!! rubber thingy back on either… how much does it matter?
Thanks
