Under sink leak with PVC
 
1 Attachment(s)
Hello all. I just bought my first house and am fixing issues here and there. I do not know much about plumbing however. I just noticed something today.

whenever i operate my kitchen sink from the left basin, it will leak. the right basin does not leak. Note the leaking by my beautiful blue oddly-shaped water drops :laughing:

the picture i have attached, i circled where it drips out of. the pvc pipe with the right arrow on it i can shake and it is loose at the connection that is circled (but not the other end), which almost leads me to believe some dinkus used the wrong size. the PVC nut is tightened all the way by hand and that pipe still is loose.

what would you all recommend or where to start?

Go get a new 1 1/2 end outlet waste and install it with the nylon bushings that come with it.

is that the small pipe that is running vertical?

Its the pipe between your 2 vertical ones coming from the sinks... If you have a hardware store you might ask them for a 1 1/2 nylon tubular bushing that goes under the plastic nut.

i would take the joint apart that leaks and make sure there is a slip nut washer under the nut and that it isn't split or broken.

aah ok. so might just be a o-ring or something? i do have a hardware store right up the rad. i will swing by there tomorrow!

ill post back with my success or failure, hopefully not the latter

There is no O rings. It's tapered plastic washers.
Looks like the area on the left has slipped down, just lossen the nut and tap it back up into place and retighten, may well be the same thing on the other end.
If that pipe does not slide up inside the fitting there's nothing to seal.
Often times when I take these apart some DIY has installed the washer backwards.
The washer is tapered and the sealing surface is tapered, install it backwards and the seal does nothing.

I would replace it all with glued fittings except for the tailpiece extensions, and the J portion of the trap.
