Awesome guys, pays bought for £5 and fixed in 10 minutes. Basin flows like a fast flowing river again now. Just need to reassemble the bathroom... Thanks again
Our bathroom basin sink just refused yesterday morning to drain away. After pulling apart all the units I managed to get to the trap, cleaned all the gunk, I then pulled apart all the pipes elbows etc and cleaned huge amounts of goo.
All that was left was a short run (1 metre) to the waste...
