Good old loop vent
Informative.
This old how to drain that pesky newel post
Why couldn't you just add an air admittance valve under the island?
Love knowing how that stuff works.
Where I’m at (Cincinnati) clean outs are required under the sink and at the wall. I guess not needed here but I like it as a cheap way to get piece of mind; allows you to quickly clear the vent portion from either direction in case of a blockage.
Looks like just a serious game of Lego Knex ….plumbers edition.
Is pex becoming the norm for residential plumbing?
I can’t take this guy Kevin.
Where’s your useless tool belt Kevin.
What I like about this video is how Richard shows and explains the vent system in this area of the house.
These videos are just so intelligent, well presented and practical. As an old guy who's worked every aspect of construction these videos are a refresher, but I always learn something new from them. Well done This Old House.
Wouldn't an auto vent work for the island?
Good content !!!
Arent there (east coast) indirect drains code for kitchen sinks? Or is that just code for commercial applications?
Whow wow wow! Slow down a little! Why do you need a vent to the island? You guys are overthinking this! Is not rocket science! For sure you don’t need a vent for that island!
No purple primer at glue joints? Wouldn't pass inspection here.
Note to self, never have an island sink.
It's almost as though Richard is intentionally training plumbers with these short tutorials.
I love TOH but how many times will they show this video
Exquisite explanation. I spotted the potential problem of a blockage quickly but didn’t know how to solve it. Richard explains so well. Nice vid
What kind of PEX piping was that? It seemed more flexible than Uponor (Pex-A) or Zurn (Pex-B)
clear as mud….thank you richard
This kind of problems are not solved by your average plumber are they?
Does anyone else watch This Old House just for fun and relaxation
Stopher vent?
This is why plumbers are worth $80/hour. NO way your do-it-yourselfer would do this correctly.
No cheater vent here, great info,
Most codes allow air admittance values
Is that a proper loop vent in your state? Not mine 2 45’s and a 90
Why do You need so much vent? We don't have that in europe.
Please add more technical information. You could easily have a 30min episode about venting!
I've hired a number of plumbers – I don't think most of them understand venting very well (I don't either). I think I know only one out of like 10 I,ve tried that I would trust to properly vent new pipes (they all only want to install new pipes they aren't interested in repairing anything)
Isn’t the middle pipe a dry vent ? Those are illegal here
where are our cleanouts? rookies!
discuss an alternate to the island vent … Oatey manufactures a ‘sure-vent’ as an alternate .. please demonstrate … thanks.
He could of just ran 1 two inch line for island and used a studor vent
Hydro you can control water you cant
