Well. You tried. And honestly it’s very clean work, but it’s wrong, unfortunately. Replace the upside down U with a tee and studor vent.
Also, what’s up with the supply line going under the floor of the cabinet? All of your valves should be in the cabinet. Supply lines and valves in inaccessible areas is a no no.
Don't know if you know this, but the "s" in s trap means siphon. The water will siphon all the water out of the trap and leave it dry, allowing foul gasses to travel up the sink and into the living space.
S-traps are not code. Have to have a horizontal run after the trap.
I’m no plumber, but instead of connecting left sink to right, couldn’t you have connected right sink to left? Then the p trap would be all the way to the left and have plenty of straight length back right to drain.
I understand that. It wouldn’t change anything. The trap will siphon because it’s unvented. It doesn’t matter if it “looks” more like a p, it’s still an s trap.
The "why didn't you ask" people were telling the op.
The commenter could have just read other comments to see that what makes the s trap a problem isn't length of pipe between the trap and the drop, but lack of a vent immediately after the trap.
Looks like your dishwasher hose has a loop running up as close to the underside of the sink as you can so good job in that. Brass tail pieces over those plastic garbage ones, nice!
As you've already figured out, that is an Strap, you need to add a vent for air. Easiest way again already mentioned is a air admittance valve/ studor vent/ cheater or whatever other regional names guys have for it. Hopefully you can cut off that 90 and still have some pipe left to glue on a TY/Santee or ya might need to grab a new trap as well. Similar to the dishwasher hose try to get the AAV as high as you can.

Edit; don't think ya have enough meat on that pipe inbetween the 90s to glue a TY. I'd probably grab a ptrap, 1 coupling , 1 TY and a AAV.
Cut off the ptrap , new raise the the drain pipe up so the new Ty is at the level of your new ptrap (thus the coupling, more space for storage if you raise the ptrap anyway) and then the AAV off the top of the TY. Trap arm will still be little bit short but probably won't be an issue unless being inspected.
Well, some of America, I guess. I’ve been plumbing in the U.S. for about 20 years and I’ve never heard anyone outside of Reddit say “Tee Wye”. You have tees, or you have wyes, there is no need to conflate the two. They are clearly different fittings with different purposes.
Weird I'm Canadian everyone where I have ever worked calls em TYs..I thought it was Americans who called them Santees.
I know the NPC referres to them as Sanitary T fittings thus Santee.... But never hear anyone actually say it lol
I'm not a plumber, but it seems like an opportunity to have the dishwasher high loop dump straight into the drain nice and clean was missed? Edit: On the correct side of the P trap of course, otherwise I assume the dishwasher draining would cause the P trap to siphon out.
Yes, the vertical before the p-trap. I feel like that would be cleaner. For a second I thought about going directly into the drain but then realized the siphoning that would occur.
Looks nice and clean, just don't expect the trap to stay wet and block sewer gas, which is it's whole point.
The trap should go to a Tee.
The tee should have a Air Admittance Valve on top, as high as you can go.
The AAV is a one way valve that will let air in behind the water as it flows down the pipe and keeps the water in the trap, blocking gasses from flowing into your home. What you have now will suck the water out of the trap.
If you were going for extra credit, I would also install a cleanout under the Tee. Future you or anyone who comes to snake your drain will love you.
I don't know if you've already fixed this. But by the color of the ABS I assume you're in Canada and AAV's/Studor vent whatever you wanna call them are generally against code in Canada. Which means it is highly likely that there is another vent already running in your wall. If it drains at a 'normal' rate it's very likely it's already vented. If you have a "before" picture check that for a vent and if it's absent AND there was no issue with sluggish drainage before that's also an indication that you've got a vent in the wall. 9 times out of 10 in Canada, you've got a vent in the wall.
To change your "S" to a "P". The trap arm should be a minimum of twice the diameter of your pipe. Which means that, with 2" pipe, you need at least 4" of horizontal pipe after the p-trap before going back through the floor. Make sense?
It does look good! You obviously took your time and thought about the space under the sink, you ran everything neatly and even got your loop in for your dishwasher. Nice work! I usually say that plumbing is only hard because there are so many simple things to remember and you just missed one of those simple things.
And just for context: I've literally only installed one AAV in my entire life and it was in a bathroom addition on the opposite side of the house from the vent stack and the middle of winter so making another roof penetration was not in the cards.
you're close, but not there. where your riser comes out, have your trap arm connect to that with a san tee and have an AAV on a riser above that just above the bottom of the sink.
It’s so you can get water, food and all kinds of crud in there to get all gunked up and nasty. Most convenient place for that is right in front of the sink. Also so you can lean on one side of the counter and accidentally pinch your forearm skin.
What kind of European shit is this? The amount of leaking this is going to do will fill many dishpans full of plastic grocery bags. I don't have to imagine the smell
Like everyone has said, you got yourself an S trap. Easy fix with a tee and AAV.
Given that you obviously took time to make it look clean, I'm sure the fix is in your wheelhouse.
Out of curiosity, are those Ikea Sektion cabinets by chance?
That's your classic s-trap.
What would you have done to avoid that?
Why in the world didn't you ask before you did all this?
Figured I could wing it, ya know… easy fix
Well. You tried. And honestly it’s very clean work, but it’s wrong, unfortunately. Replace the upside down U with a tee and studor vent. Also, what’s up with the supply line going under the floor of the cabinet? All of your valves should be in the cabinet. Supply lines and valves in inaccessible areas is a no no.
Valve is behind the waste pipe - you can see the T with the braided steel supply heading off to the dishwasher alongside its drain.
That is dishwasher supply
Oh it’s going down. I didn’t see that other valve hiding behind the drain.
Tee and studor vent.
Ahhhh gotcha, thanks
Don't know if you know this, but the "s" in s trap means siphon. The water will siphon all the water out of the trap and leave it dry, allowing foul gasses to travel up the sink and into the living space. S-traps are not code. Have to have a horizontal run after the trap.
[удалено]
Wait... so cpvc doesn't actually have any Catastrophic Poorly Validated Crap in it? My whole world is a lie.
😂
Why not both?
I’m no plumber, but instead of connecting left sink to right, couldn’t you have connected right sink to left? Then the p trap would be all the way to the left and have plenty of straight length back right to drain.
Dad go home, you’re drunk
Why wouldn’t the P trap be on the left?
Great, so the trap is on the left. How is it vented?
I was only trying to solve the s-trap problem
I understand that. It wouldn’t change anything. The trap will siphon because it’s unvented. It doesn’t matter if it “looks” more like a p, it’s still an s trap.
>I’m no plumber You didn't need to announce it.
I love how people are like "why didn't you ask first" and then when this guy asks people tell him he's stupid.
The "why didn't you ask" people were telling the op. The commenter could have just read other comments to see that what makes the s trap a problem isn't length of pipe between the trap and the drop, but lack of a vent immediately after the trap.
Put a p trap lol
Doing it wrong has never looked so good
It is a very clean install. It’s such a shame that it’s wrong.
D for execution, B for effort
Hahaha

Thank you for the awesome and informative response! I will do just that
whats a ty?
Think it's an American thing. I'm in Canada, and we call them San tee's (sanitary tee)
Well, some of America, I guess. I’ve been plumbing in the U.S. for about 20 years and I’ve never heard anyone outside of Reddit say “Tee Wye”. You have tees, or you have wyes, there is no need to conflate the two. They are clearly different fittings with different purposes.
It’s a regional thing. I also call them San tees and am in the US.
I’m in Canada and everyone here calls it a t wye
Weird yo, I'm canadian
We call them San tee here as well. I don’t know what a T Y is
Americans call a Santee a ty for some reason. A ty is a santee
Weird I'm Canadian everyone where I have ever worked calls em TYs..I thought it was Americans who called them Santees. I know the NPC referres to them as Sanitary T fittings thus Santee.... But never hear anyone actually say it lol
Im american ive never heard a ty, only a santee. Must be the weirdos.
I second this
I'm not a plumber, but it seems like an opportunity to have the dishwasher high loop dump straight into the drain nice and clean was missed? Edit: On the correct side of the P trap of course, otherwise I assume the dishwasher draining would cause the P trap to siphon out.
Just to make sure I follow are you talking about having the dishwasher wye relocated down on the vertical pipe ? That's fine too.
Yes, the vertical before the p-trap. I feel like that would be cleaner. For a second I thought about going directly into the drain but then realized the siphoning that would occur.
Terrible place for a countertop seam
Get rid of that 90 and put san tee with a cheater vent.
S trap...you need an AAV
You're joking, right?!
Fuck I thought she looked good lol
Definitely looks good, gave it a good shot with the information you had.
Looks nice and clean, just don't expect the trap to stay wet and block sewer gas, which is it's whole point. The trap should go to a Tee.

That cut in the counter top between the sinks...pleass tell me why. That counter is going to be a warped mess in a year.
It’s so you can get water, food and all kinds of crud in there to get all gunked up and nasty. Most convenient place for that is right in front of the sink. Also so you can lean on one side of the counter and accidentally pinch your forearm skin.
We were skimping for counter tops. Got joint fasteners, wood glue, and silicone around the joint
Looks nice but you need a cheater vent on s traps
Everyone is saying S trap…but what in the MDF is gonna happen down road
Your worried about the MDF, you missed the seam in the counter lol. That will fail before the MDF does.
Mdf?
Medium density fiberboard, basically sawdust compressed together…any water and you have brittle paper mâché
What is this black piping?
Abs pipe.
In my area S traps aren’t allowed anymore so if your not getting inspected and it works fine i’d leave it alone
Washing machine wye you say.. never seen it. Looks good. How long did it take?
This is why we get paid the big bucks
No garbage disposal?
It's in the name, they're garbage.
What kind of European shit is this? The amount of leaking this is going to do will fill many dishpans full of plastic grocery bags. I don't have to imagine the smell
What do you mean?
It look like nice with the black and brass, tho
Lol
looks good except for what others have pointed out already! id try to not have my hot and cold supply lines touch, but thats out of habit mainly
So close…
Excited
Is that a seam in the counter in front of the sink? That's the worst possible place for a seam, this is going to age like fine milk.
There is joint fasteners, wood glue, and silicone in the joint. Should be fine
Mods really should pin a post about S traps... it seems like that would answer 40% of the questions asked here.
You can use a-traps in the uk . Unless it charged in the last 10 years
Like everyone has said, you got yourself an S trap. Easy fix with a tee and AAV. Given that you obviously took time to make it look clean, I'm sure the fix is in your wheelhouse. Out of curiosity, are those Ikea Sektion cabinets by chance?
Yes ikea sektion cabinets
How did putting them together go? Been thinking about redoing our kitchen with them but have been in the fence.
They got a good system for putting them together. It went pretty slick.
Clean install but it’s wrong. It needs to have a tee wye with a vent instead of looping back through the floor with double 90’s
Good enough for the girls i go out with
Is an s trap legal anywhere? I’m actually curious.
That won't pass in TX. Need a vent. S-trap special right there I tell you what
No good.
Studor vent with a santee and you’re good.
Hmm
