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.

Loved the defunct new primer lid! Was the brush in the can (broke off) or not there at all? Good video btw!

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.

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.

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 🤦🏻‍♂️

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?

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?

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

@realexperiences8748 5 ай бұрын

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.

Shouldn't you have installed an air admittance valve instead?

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

@simonpaine2347 Жыл бұрын

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.

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

@egondzintars8209 11 ай бұрын

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 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.
