That 3" combination serving that toilet should have been a 3" long sweep. Before that combination, you could have put a 3" wye to serve your sink. That would have been your vent to. Then make sure that you are not close than 15" center to center of your fixtures.

that vent is required to be above the flood level of the fixture! It will leak in the future.

Cutting off a sewer pipe just above his canned good storage! Not eating at his house!

Thank you so much for useful video ❤

There is so much wrong with plumbing in this video that I don't know where to begin. To everybody who is watching this - please do not follow this DYI's instructions. Consider yourself warned. Thank you

Hey buddy just keep both vents it will probably work better .

Does not look like this would pass a plumbing inspection. Never thought it was a smart idea to put a Studor vent BELOW the fixture it was supposed to vent. It the under sink Studor was installed correctly then a 2" vent would be enough to vent the crapper. Total distance from the centerline of the flange doesn't look to be over 5 feet or so. Please follow up in the future when you have a sewer line blockage and the effluent backs up to your vent.

This is wrong . You need a 3"x 2" wye before and within the code distance of the 3" toilet 90 or a 3" x 2" side outlet 90 at your toilet . The the 2" of either of those configurations runs to your Lavy ( sink ) . The in-line vent should be 6" above the flood level rim of your lavy to prevent debris from clogging your vent in case of a drainaige back up . . Now , with what you did , the sink also has no vent . This is supposed to be a wet vent configuration . Where the lavy can vent the toilet . It's best to run the 1 -1/2" lavy vent thru the roof . That's just the beginning of what's wrong with this . Sorry .

What did you put on (like a cap) at the last step right before the flush test?

Thank you! My vent is letting moisture come into the cabinet underneath my kitchen sink. I think I will replace the vent and see if that helps. I have a feeling the vent might be all in this faulty???? Any suggestions?

Can you hook up a studar for all bathrrom fixtures?

My kids restroom toilet is doing the same thing and has a nasty smell no matter how much a clean it. Is that a sign it needs to be vented?

bad bad jobber !!!!!!!

Code ? Never heard of her 😂

"It's a little pasty!" That's legit. lol

What if you install the vent on the 100mm pipe not the 50mm does it still do the same work ?

That toilet is wet vented thru the lavatory and a toilet can be unlimited distance from a vent because it’s a self siphoning fixture.

How big is that Oatey vent 3 inch or 4 inch?

Also, it's installed too low. After watching it fully, I see you moved it up.

Can you put the air vent side way or it have to be up right?

It looks like you went way down in pipe size you need to keep a large vent the same size otherwise I think it will have that problem

The plumbing is done wrong. If it were pipe correctly, it would not have been a problem.
