If you have a sink in a slide out you may want to inspect the installation. In my bathroom sink and closet slide the black ABS pipe the sink drain pop up assembly connects to was not attached to prevent it's flexing and moving each time the slide moved in or out.
On my sink the entire weight of the flexible drain pipe and the black ABS pipe were all hanging on the sink's pop up drain assembly. I found this out when the pop up assembly snapped right at the bottom side of the sink dumping water into the undersink storage and subsequently on the floor and my feet!
I used steel plumber's tape and secured the black ABS pipe in four locations so that only the flexible hose under the sink, not the entire drain assembly, moves when the slide is used.
Fortunately the pop up assembly is a standard plumbing part and was available at Lowes. Harold
