Hi Guys I wonder if you can help? My waste pipe from the kitchen sink u bend is going into a drain outside (link 1 below) which seems to be overflowing causing a water mark on the wall. Separately the pipe above the drain (link 2 below) doesn't fit securely into the down pipe going into the drain. Under my sink the u bend is dripping. Water can flow freely out of my sink, the sink isn't 'blocked'. Do i need a plumber or drainage expert? https://www.flickr.com/gp/154345826@N08/1861W6 https://www.flickr.com/photos/154345826@N08/37028823391/in/album-72157685769846233/ Any help greatly received. Many thanks Dan
Should be easy for yourself to try sort yourself Orange cap in first picture should lift off and if it's full off water I'd try a wick mop and plunge it to short the blockage.
