Seriously, thank you for this. I wasted so much time today between the house and Lowe’s I was about to give up. Your video explained my problem perfectly. P-Trap first, everything else after should just be glued and fitted to meet the floor instead of wasting time with all these screw on fittings. 90% of the videos on UA-cam are regular P traps without a wall drain instead of the floor.
Good catch - and warrants some clarification. First solution would be an Air admittance valve - While not all codes allow one, it would be easy to install one here by substituting the 90 degree sweep from horizontal to vertical with a sanitary T and then placing the air admittance valve usually about 6 inches above the horizontal portion of the P trap. Second would be to create an upside down "U" to create a loop so, a sanitary T to replace the 90 elbows, go up about 6 inches put on a 180 bend and go straight back down. The loop was not chosen since this is a retrofit (just new cabinets and sink) and would be difficult and costly to install. The air admittance valve while possible, is not needed given that the piping for this single fixture is arguably considered oversized as under the floor it quickly increases to 3 inches and the distance to a vertical vent that goes through the roof is about 2 feet. In summary, I would put it this way: a good, better, best scenario. Best would be the air admittance valve, while the better scenario would be what is shown in this video. This would work 100% fine with normal usage. Maybe warrants a follow up video on the specifics since plumbing is simple yet complicated.
This is an S-Trap with a length of pipe added at the top of the S. You didn't create a P-trap, and it won't stop any siphon action as it's missing that vent pipe behind the wall.
Thanks for the video! I'll be doing this later today. Id replaced the faucets that went bad around 6 months ago. And I should have known the assembly would need replacing too!
I'm pretty sure that's still an S-trap. You need some kind of vent where the elbow that turns down is. At the very least, using a T instead of the down elbow and putting an air admittance valve on the top of a T.
Need the sand tee with a vent on tub your not doing a waste arm inside the wall drain is coming from bottom up and need the stud vent unstead of using that 90 should be a sant tee just and advice Godbless
@ChipChurp OK??? So you say a handheld dish sprayer is a source for venting ??? Where I am at ...Always thought a handheld dish sprayer is a source for water. There is a difference in a vent line vs. a supply line.
Disappointed! The diagram on the lead in, shows a vent! I wanted to see what kind of vent you installed and all you seemed to do was install a slightly extended s trap. I'm guessing that this will syphon depending on where the vent in the system is, if indeed the system even has a code compliant vent installed.
The piping for this single fixture is arguably considered oversized as under the floor it quickly increases to 3 inches and the distance to a vertical vent that goes through the roof is about 2 feet from that point. This will (and has) will work fine.
I have the same situation, if I were to put a Tee where the drain is going through the bottom of the sink, then a elbow with a pipe extending up with a Studer vent would that be OK?
So I’m doing this and I am set up to have a Tee connected to the P-Trap. I plan to stub up about 6 inches and put Air Vent above the Tee and below would be drain out. Hope that’s correct.
Funny u talk about no to do s trap and you did one ,instead of the 90°,use a 1 1/2 tee and on top of the tee use a short piece of pipe and on top install a in line vent
One of the most informative videos I've seen. Thank you for all the details, reasonings, and thorough explanations.
Sorry, it's still incorrect. He drew it right, but his install was the same as an s-trap if not worse.

Vent? All traps need venting in all cases. Without a vent, the water seal in the trap gets sucked out and sewer gases can enter the room.

Thanks guys! New project for me.. will get an air admit valve too😊
What did he solve by doing this?
This is an S-Trap with a length of pipe added at the top of the S. You didn't create a P-trap, and it won't stop any siphon action as it's missing that vent pipe behind the wall.
This is what you call a long s trap. "Capital S trap? Lol
Spanish S?
He should've installed an air admittance valve, right? I'm just learning about plumbing...
May i use P-Trap in kitchen sink?
Hi there sinks have a flat bottom discharge which it means it prime's the trap ,same as a bath
Thanks for the video! I'll be doing this later today. Id replaced the faucets that went bad around 6 months ago. And I should have known the assembly would need replacing too!
Please tell me you didn’t follow his instructions? He literally made a S trap after saying no to do it 🤦🏻♂️
Nice, but what if your old house floor pipe is in a straight line to your sink hole?
I'm pretty sure that's still an S-trap. You need some kind of vent where the elbow that turns down is. At the very least, using a T instead of the down elbow and putting an air admittance valve on the top of a T.
It's an unvented P trap
Can I attach the connection hub directly into the elbow without having a small piece of pvc pipe between the elbow and the connection hub?
S traps have been used forever and now people act like your house will collapse if it is used. Bizarre
Need the sand tee with a vent on tub your not doing a waste arm inside the wall drain is coming from bottom up and need the stud vent unstead of using that 90 should be a sant tee just and advice Godbless
Hi on a sink a short pipe is code on a hand basin it is not eg a trap vent or a 300mm. 600mm horizon tal 30 to 1 fall
Loved the defunct new primer lid! Was the brush in the can (broke off) or not there at all? Good video btw!
Shouldn't you have installed an air admittance valve instead?
Thanks!
Didn't you just create an s trap after all that?
Great video once again! Excellent job Hammer & Pine!
I wish my kitchen sink was just one pipe, We like 4 under there, garbage disposal & the wierd way the old metal pipes were hooked
You need to use an AIR ADMITTANCE VALVE for venting.
No you don't depending where you are at. Some have the handheld dish sprayer that serves that purpose
@ChipChurp
OK??? So you say a handheld dish sprayer is a source for venting ??? Where I am at ...Always thought a handheld dish sprayer is a source for water. There is a difference in a vent line vs. a supply line.
Where is the vent pipe?

I can always tell a novice from a pro by the terms they use to describe the parts they are using," connection hub"?
this is terrible. After all your talk about P traps all you did was install an "S" trap which is against code. Where's the AAV?
I was watching this and I'm like that's the wrong trap why am I watching this
I have the same situation, if I were to put a Tee where the drain is going through the bottom of the sink, then a elbow with a pipe extending up with a Studer vent would that be OK?
@@atvridgerunner tee wye with a fitted end clean out on the top if the drain is back vented
So I’m doing this and I am set up to have a Tee connected to the P-Trap. I plan to stub up about 6 inches and put Air Vent above the Tee and below would be drain out. Hope that’s correct.
It is still an S-trap, or simply an un-vented trap. At least install an air admittance vent.
Thats still an s trap tho
Funny u talk about no to do s trap and you did one ,instead of the 90°,use a 1 1/2 tee and on top of the tee use a short piece of pipe and on top install a in line vent
Improper installation
Sorry Bro you accomplished nothing!,, you should have showed people how to install a auto vent!! Just saying!!
Wrong! This is still S-trap and will siphon the water. I hope you are a DIY enthusiast. Not serving customers.
So how do I know if I've accidentally made an S trap?
A: It will smell like S
How do I know if I made a correct P?
A: If it's a P, it's odor free.
