So I decided today that I was going replace the kitchen sink with a stainless one and also replace the unvented s trap with a p trap vented via an AAV. Simple enough right? Not so much.

First fight was w/ the old rusted out sink clips. There were 14 holding it in place - I managed to remove 6 successfully and snap the heads off the other 8. Luckily they all had small pieces of wood between the screw and counter so I spent 2+hrs busting the remaining 8 small pieces of wood out. I thought that was the frustrating part...then I got the slip joint blues.

Went to lowes and got everything I needed, installed it & hooked up new flex lines in about an hour. Turned the shutoff valves back on, no leaks, but didn't really expect any from the compression lines. Ran some water and watched the drain...saw some water building up after about 30sec. Left it run for a couple min and found leaks at 3 joints. Took them apart and made sure the wedges were facing away from the nuts and that the pipe surfaces were clean. Tried again and still had 3 leaks. Repeated my first attempted fix, tried again..2 were leaking. Attempted fix a third time, tested again, still had 2 leaks. I gave up.

Sitting on the kitchen floor in self defeat I told myself I'd just do it all in sch40 pvc and glue it. Never had any issues before w/ glue and the 1.5" unions are solid. Figured I could put in two so the trap can be removed. I know it will be more expensive but at this point I think it will be worth it for my nerves.

My only question ends up being whether or not there is a sch40 fitting to hook up the dishwasher drain hose?

Post a picture of what you have.
I can not see where having this drain all glued instead of slip joints is going to to be the best way to do this.
A simple clog is going to turn into an 1/2 day job to fix doing it that way.
Somethings fishy to have that many leaks.

Simple slip joint lesson--

Nylon washer---narrow part to the fitting--thick side to the nut----

Always run your finger across the mating surface and feel for any burrs --(casting flash) remove it if found.

Use a tail piece washer where the tail piece meets the strainer basket.

Hand tight is good ,if you have strong hands---a little help from pliers if you are weak.

Make sure the parts fit-----and you have the P-trap assembled correctly.

Post a picture---no need for glued parts----

Well guys I let it drip this week and gave it another shot tonight. I looked for casting marks and could feel them at both the leaking joints. Lightly filed them smooth, reattached and voila! No leaks. Thanks for the tips, saved me from spending more money on a glued setup out of frustration.

I ditched the s trap entirely and went w/ a vented p trap. Does that look up to code now? I have a plastic bag tied over the dishwasher drain stem as that's my next step in the process.

Man, I wish I had gotten some stock in slip joints before you started this one. I bet the stock doubled and split! :thumbup:

Nice job bro. Glad you added the vent..

Funny you mentioned that. Some of the neighbor's slip joints just knocked on my front door, they said they heard there was a party at my place. lol

When you first posted about this project I expected some questions on how to pipe through the floor and make the connection below- must have been pretty painless :thumbup:

Yes pretty painless. The drainpipe goes straight down & out the basement wall. It's some kind of metal, maybe copper? (pic below) Anyways it sticks out just above the floor below the sink and has a flanged male thread. The old setup had a plastic wedge washer and a nut, so I did the same and no leaks so...yay.

On a side note, I do plan on replacing the flex dryer vent w/ rigid. :-)

So--Did you ever get it to stop leaking?

I would have used glued for the riser and AAV---an made that riser taller, so you had less length from the sink to the P-trap.

fetzer85 04-05-2013 06:52 PM

Yes its no longer leaking.

I could bring it up some but the AAV is in line w/ the cross section - so it could come up a few more inches.

Do you glue tubular pvc the same as sch40?

oh'mike 04-05-2013 07:08 PM

Never glue the slip joint tubes---the schedule 40 is what you use for any glued sections--

If you are not leaking---sit back and relax----Job done---

jagans 04-05-2013 08:08 PM

OP Unless I am blind, The T at the bottom of that copper pipe is backward. Am I seeing things?

"I had the slip joint blues, I thought I paid my dues, but now I got a reverse T, and that is really bad plumbing news"
:rockon:

fetzer85 04-05-2013 08:27 PM

Hah, you're right. I had to go look at it in person to see. Sure enough it curves back towards the clean out end. That one's staying........

jagans 04-05-2013 09:16 PM

It wont be long Yeah Yeah Yeah, Yeah Yeah Yeah, It wont be loong..........owwwww yeah.
