Wife has just informed me we have a leak under the sink. I'm going to drop in screwfix and try and get the parts to fix it, on the way home this evening. I only have a couple of images to work with and don't have a clue what I need. Can anyone assist. Wife says the metal screw is broken.
Pipe to the right leads to the washing machine. Pipe on the wall is the water inlet. Above this (can't see in pic) is the sink outlet. This is in a kitchen cupboard under the sink.
Can anyone make sense of this? Wife is out now and it's a bit of a drive to go home then back out to get the bits.
