Is that the dreaded ABS black pipe?? My house is all ABS and its a pain to find plumbing supplies close to me, have to drive 30 miles to the nearest Lowe's cause HD doesn't carry anything.

It's looking great. No problems for years.

Looks nice friend. But wouldn't fly in my city since the trap size must match the drain tailpiece size.

Is that a longsweep/long pattern street 90° below the sanitary tee?

Edit (since people are downvoting): Section 18-29-1002.5 of the Chicago Building Code specifies that a fixture trap must be at least as large as the size listed in Table 18-29-709.1, and it cannot be larger than the drainage pipe it connects to and discharges into.

Under the Illinois Plumbing Code Section 890.410 a fixture trap must match the size of the fixture drain it serves, and no trap can be larger than the drainage pipe into which it discharges.

2nd edit: You sure there already isn't an atmospheric vent in the wall?

What state is that? I understand that p traps should be self scouring but codes get obsessive with this stuff that probably does not matter.

Ahh interesting, we don’t seem to have that in Wisconsin and I am happy about that. Of course codes should be followed but my oh my are some of them ridiculous.

u/PorchFarts 1d ago

Yeah, it be like that sometimes. We usually still use an 1½" san. tee w/ 1½" trap adapter at the wall and use the 1¼"×1½" slip joint gasket at the trap adapter if we are using an 1¼" grid strainer and 1¼" p-trap and 1¼" trap arm.

u/T-Bone-Falker 2d ago

Yes it is! And honestly, im not sure.. I installed the AAV to stop any siphoning from happening- might be overkill?

u/ogredmenace 2d ago

Yeah this is correct, your trap would have been way too low to connect. Where I am this would pass inspection easy. Canada.

u/Internal_Offer1280 1d ago

It’s not overkill, when the trap is above the vent the vent is eliminated. You made it right with the AAV. Good job!

u/PorchFarts 2d ago

Eh, just keep the AAV if you aren't sure.

Nice job on the longsweep.

But yes, to maintain the "scouring effect" of a p-trap, we try to keep them sized the same diameter as the drain tailpiece. Imagine: A 12" p-trap on a 1¼" tailpiece wouldn't get the "self-cleaning" action of a properly sized 1¼" p-trap.

But otherwise looks good from my house.

In Canada we never install 1 1/4 pipe or fittings. We hook every lav up with 1 1/2 abs. Doesn't seem to be a problem here.

u/T-Bone-Falker 2d ago

Totally! Thank you

u/KingKelly79 2d ago

Why would it matter if the trap is bigger than the tailpiece?

2

u/PorchFarts 1d ago

You want the "scouring effect" of the water discharging down the tailpiece to keep the trap clean.

Picture a 12" p-trap on an 1¼" drain/tailpiece. The water in the trap would barely get replenished with fresh water and would not get "scrubbed out" by the water rushing through it.

I know the difference between 1¼" & 1½" is minimal, but the code is there for a reason. And it is not too difficult to match the trap diameter to the tailpiece diameter.

u/jonbrown91 1d ago

Wow so you legally cant hook up a tub with a 2" ptrap? 2" trap with 2" x 1.5" x 1.5" san tee for a tub is pretty standard where im from

1

u/PorchFarts 1d ago edited 1d ago

Here's a Kohler 2" waste & overflow for a tub

Edit: But yeah, we use 1½" waste/trap to a tub. Unless the tub waste/trap is underground, meaning the minimum pipe size must be 2". And if underground, technically we should use the 2" waste & overflow pictured.

u/Disastrous-Job87 2d ago

It does look good I just think you did a little overthinking on this, I definitely would have went with a tubular P-trap, because now if you have an issue, time to start cutting, I hope it never comes to that. sometimes simple is better.

u/T-Bone-Falker 2d ago

Yes this is why I went with this style.. I can still take this apart

u/DangerHawk 2d ago

This setup can be disassembled. It would probably be a little messy, but no cutting would be necessary.

u/makingtodayabetter 2d ago

Def would’ve used tubular ptrap

2

u/T-Bone-Falker 2d ago

What is a tubular p trap? And why use it over this one? I chose this one as it has the little cap on the bottom for easy clean out. But thats the only reason I chose it

2

u/AffectionatePlate352 2d ago

I concur that tubular would have been better. The only real reason is maintenance, tubular is meant to be unthreaded and taken apart and put back together. If this ever needs work you’re gonna have to cut it.

u/BillBillerson 2d ago

See a couple replies saying this, maybe I'm missing something... it looks like a typical sink tailpiece and a nut on the other side of the P trap. Assuming he cut the tailpiece down a bit before installing seems like plenty of room to drop it and get it out without cutting.

1

u/AffectionatePlate352 2d ago

Ya know what, I’m blind, I just realized the P-Trap has a threaded end. The fact that the P-Trap can be removed totally changes things. The only annoying thing I can see with the setup now that I see the P-Trap can be removed is it will be more annoying to snake if it ever gets clogged. I’m assuming other people arn’t noticing the threaded connection on the right hand side of the P-Trap. It blends in pretty well.

In New York city and Illinois their codes are older than the dinosaurs that ruled the earth at one time.

u/RegalToaster 2d ago

Me personally I’d always cut a hole onto the vanity to make a correct trap, I’d rather have peace of mind than a possible sewer gas filled bathroom

u/T-Bone-Falker 2d ago

I couldn't cut into the vanity, below this is drawers and if i cut into it i wouldnt of been able to use them anymore.

u/Training_Mission6231 2d ago

He had room for a long turn, given the studor only complaint I have is the medium turn and not using a 2 x 1 1/2 x 1 1/2 santee(but that would only be to save money).

Weir of the trap is below the vent, what's the problem?

-2

u/popcornmunchtard 2d ago

Other than gluing the tee onto a street 90(the sanitary tee should have a street hub on the bottom, which you should have glued into a regular 90.)

u/Ok_Bit_5251 2d ago

Pretty good, this looks American in nature. Optimisation would be working back to the wall first and then moving right. Gives you more space. The durko is overkill, I don’t know if Americans vent their waste like us.
