So a picture landed in my inbox the other day? Im referring specifically to the looped drain. Does anyone have any ideas?
This is in the lower ground floor of an old building (1800s). Its new though, of course, the other side of the breeze wall is a small kitchenette with sink (waste seems to connect directly to a separate manhole there) and a WC which also has direct connection waste. As mentioned, there is another manhole just the other side of the wall, but neither this access chamber seen here nor that other one could be lifted by the person there at the time.
The loop seems to rise above the overflow level of the sink which might suggest its connected for some reason. You can just about see a rodding eye on the far loop...
Imagine the picture turned 90degree clockwise... 'cos apparently I'm not able to flip this now it's been uploaded.
I don't remember coming across this before? Any drainage experts able to shed some more light?
