leak under kitchen sink

JP79ST

HI everyone,

Today I noticed water leaking out of the cabinet under the kitchen sink. So I looked in that cabinet and noticed a significant leak. The leak is due to two pipes not even being connected, although that wasn't obvious until I touched the pipes. This is strange since I didn't disconnect the pipes and I can't imagine anyone else did either. See the pictures.

Assuming the pipes were originally connected, I can't tell how. Perhaps they were glued or perhaps some connecting part fell off. Does anyone know if this is a quick fix, and what to do about it?

Thanks.

It's a compression fitting
Unscrew it, push it back up, then screw it down tight
Most likely someone just hit it...maybe a few times over the years & it eventually slipped off

That worked...Thanks

The waste arm shown in the picture is of a lightweight plastic and these while cheap are prone to lossening over time. Your draining hot then cold then hot again........over time the expansion and contraction loosen the fittings. They are supposed be hand tight ONLY. You'll just have to keep tabs on them. One thing I like to do under sink and basin cabinets is to put down those inexpensive 12 x 12 self stick tiles. I lay them down and cut some in half to seal the sides (up 6"). That way any leaks or spills from all the under sink chemicals most of us have won't rot the bottom of the cabinet. Have fun.
