I'm new to the forum and have searched for a topic related to mine but was unable to fine anything so here goes my problem...

I just installed my drain and PVC plumbing. The opening from the wall comes in from the side which extends about 21" to the drain. Once connected there's a slight build up of water around the bottom of the bend (black arrow, around the connection) and I believe a small amount of water is coming from the tail piece where it screws into the drain (red arrow).

Why might this occur? Could someone offer some possible causes?

Thanks in advance!

not being a smarty pants..but it is caused because it is leaking. Did you use plumber's putty under the flared end on top? If the threaded portion is leaking disassemble it and use some pipe joint compound on the threads. If it leaking at the nut with the nylon washer inside you can probably tighten it up a little (check to make sure it is fitting good). If you had to give it a little push to one side or the other then you need to re-set so that no force is required to move it in line so that the drain drops easily into the trap with a very good and easy fit.
 
leaks

The black one would leak because it is not tight enough. The red one looks like where the tail piece screws into the drain, although I don't know what that black stuff is. It should have a joint compound on the threads and then tightened very snugly. If it is leaking from the rubber gasket, then loosen the big nut and apply some joint compound between it and the rubber washer, then retighten it.

Yes, it's where the tail piece screws into the drain. There's no black stuff, it's just the angle of the picture. I have no compound applied anywhere and will give this a try tomorrow. Thanks guys!
 
I had a nylon washer leak because it had a little piece of plastic flash on it from when it was manufactured. I sanded it off and ---no leak. I put silicon caulk on the threaded metal to metal shaft--plumbers putty seems to get completely forced out of the threads.
 
thread

Plumber's putty was never intended to be used on threads. That is why it is wiped off when you thread things together. Silicone caulk was not either, so I hope you never have to take the threaded connection apart.
 
To my knowledge...plumber's putty is intended to be used to make a seal between a fixture and the parts mounted on it (faucets & drains). However, I have seen some creative uses i.e. makeshift washers, packing where washers don't do their job, plug up all kinds of holes (used for caulk replacement)...

Like Kd.. I've had to smooth places on plastic parts where they had ridges or something a little extra when they came out of the mold.

Um, if that drain's running parallel to the wall, how's it vented?

The pic is taken from underneath the cabinet. The cabinet is attached to the wall via a French cleat from the rear and the left side is up against the wall, no legs. The vent is to the left, not visible in the pic.

I generally have the best luck with a bit (1 or two wraps) of teflon tape on the fine threads of the 1-1/4" tailpiece where it screws into the drain. any more than that tends to clog the threads and pipe dope does not seem to work reliably...
As far as the black arrow, I concur with the others - it is probably a seam or flaw in the plastic or nylon washer...
Take it apart and sand it out...
 
I purchased a different POP-UP, the Keeney Lavatory 1688K. It comes with a puttyless washer. Have you guys had experience with these? The second step says, "apply suitable sealant to underside of flange or use puttyless washer and insert flange into lavatory drain hole".

Also, if you look at the pic below notice the bottom nut (black arrow) screws upward. I notice while at the HW store today that most screw downward. Does this matter? Might this be the reason I experience a small amount of leaking?

It's an old concept for hanging cabinets.

On that French Cleat cabinet mounting system ...

In Europe from what I've read people "take" their cabinets with them when they move. Or should I say have the option to.;)

(Makes sense if you have some big $$$$$ cabinets... and the new buyer doesn't like the style...)

Big plus also is if the cabinets are totally removed from a wall is that it leaves nothing more than two ¼ "-diameter holes to patch.:cool:


.
 
I tightened the nut (black arrow) and I'm still getting water. It doesn't happen right away but I left it over night and see water has collected on the rim of the nut (black arrow). I guess I should try compound?
 
If you're positive that it is seeping up thru the threads... I'd wrap it with teflon tape...or use TFE paste/joint compound...not the regular gray plumbing stuff... TFE is especially for plastic.
