Are these traps set up properly?

When I run water in the kitchen sink I often notice a foul smell, I was wondering if these traps might be letting gases past.
Thanks!

No, they are not proper. Those are effectively set up as S-traps, and unvented at that. So when water runs, the suction can siphon the trap out, releasing sewer gas.

Should be set up like this with an automatic air vent...

You can only have one trap...

What would be good way to resolve this? I mean how should I run the pipes given my setup. The steel pipes come from a disposer and the white pipes from the other sink basin.
Thanks!

Imagine that the disposer is hanging on the right in lawrosa's picture.... and do it just like that. Use a straight discharge pipe to come out of the disposal.... no need for a down elbow. (But reverse everything for your situation.) And put the AAV up high as you reasonably can.

Like this kind of.. But use a straight tail piece out of the disposal instead of the black ellbow they show...

Would the tail piece from the disposal have a downward slant to it or just straight across into the other pipe?
Thanks!

I was wondering how to resolve the fact that the discharge pipe from the disposal comes out at an angle such that a straight pipe out would end up behind the white pipes. How can I get that to work. The pipe out of the disposal will have to join the white pipe from the drain. I saw a video wherein "flex tubing" was used, kind of a flexible plastic but I haven't been able to find a product by that name.
The pic isn't great but gives an idea of what I'm talking about.
Thanks!

The disposal will rotate 360 degrees... all you have to do is turn it.

If you loosen the disposer from the steel flange (sink drain) you will be able to rotate the disposer so the discharge points to the direction you need.

You will need to cut that whole mass out. Get a coupling on the pipe down at the cabinet floor. And repipe the whole thing...

Youll need.

1 glue and primer
2 One p trap 1 1/2
3 one air vent 1 1/2
4 one 1 1/2 sanitary tee
5 one coupling
6 5 ft 1 1/2 pvc pipe
7 one side waste drain kit
8 two 1 1/2 tail pieces. One long to reach other sink..

Your going to turn the disposal and put a straight tail piece out after you remove the elbow thats there...

OOOhhhh I found one......


It should look like this when done!!!!!!


But you probably dont need that extra piece that makes the trap so low... Since your repiping the back piece with the tee and air vent you can make it to exact height you need,,,,

Yes. See post #14... bottom pic.

Cut on red line, replace it with a coupling.

In going from the p trap to the hub, is the idea to cut a short length of PVC and glue one end into the hub and the other end into a trap adapter?
Thanks!

Yes.. Whatever length it takes to get you closer to the trap arm...

I assume your using the elbow off the disposal?

I'm not sure. The guy at HD was persuading me to, saying a straight pipe could pop off from the pressure out of the disposal. I'm not sure that's accurate but he also said I could cut the elbow off the white pipe and go in straight. I have to look at the disposal pipe and see how snugly I can connect a straight tube as it will only held on by a spring type hose clamp.

See the metal adapter on the GD? You slip the tail piece through it....

The top piece coming off the top of your tee should also be a tail piece and not the tail piece adapter as you show...

Thanks!

Yes, it's an evolution pro essentials. I unscrewed the hosing assembly but there doesn't appear to be any threads or any way to screw an adapter in.

What did you unscrew? Did a metal piece come off with a hole in it? No you dont thread anything in...

The instructions show a tailpiece can be used but I need to see all you removed

Ill read through instructions again...

There appear to viable options for connecting the GD so I put that on the back burner and went beyond the point of no return by cutting out all the old piping. I used a hacksaw and you can see the results. Is this OK or do I need to get a smoother more even cut? Does the Tee just glue in place there?
Thanks!

That cut is fine... But you dont put the tee there... You put a coupling and a piece of pipe to the height you need for the tee...

Did you not understand the pics??

You better dry fit all of it and let use see it before you glue.... ..

I only hope its not too late....lol

Sorry for my previous question, I hadn't thought it through yet. Anyway I went ahead and did the job. It ain't pretty but hopefully it won't leak.
Thanks for all the patience and help lawrosa!
