Understanding Bottle Traps | Ask This Old House

[@Bonzomallard]

Bottle traps are quite standard over here in the UK. They work well and if there is a problem you easily undo the ‘bottle’ clear the blockage and continue for another decade until it needs servicing.

[@Brian77766]

Yes, I don’t see a problem with them, with most of them consisting entirely of PVC, they basically last forever. Plus they’re easy to clean out and great for capturing that ring that fell off you finger. The US needs to get a grip. How about your US bath trap that you can’t clean out? Good luck with that, and they say it’s code compliant?!

[@eaglevision993]

We have them in Germany too. I don´t see a problem with them. They can be disassembled to clear a blockage. And I have NEVER seen one fail because they rot through. But then again we are talking about US quality here....

[@ptso7580]

We have em in the US. It's just not popular because it didn't come in our cheap homes built by criminal developers from the end of WW2 to now.

[@htklun]

I can understand why it would not be code compliant when plumbing fixtures were made with metal that can and do corrode over time. In Asia thick gauge PVC bottle traps are pretty common and they are absolutely rock solid and will last over 30 years. I’ve never had any problems with them.

[@demonknight7965]

The other issue richard was talking about is it not completely cleaning all the water out of itself. There will be some of the nasty water left in there.

[@Engineer9736]

@@demonknight7965 The water does get refreshed, but not as efficient as using a S trap. Similar to ventilating a room, the airflow from window to window is also not a tube, yet the turbulence in the air causes the entire room to have fresh air after a bit. The bottle trap does the same.... if you let the water run for a few minutes (regular usage) then all the water in the bottle trap has been flushed through. During normal usage the dirtiness of the water in the bottle trap doesn't matter anyway. And if you need to clean it, put some gloves on and a bucket underneath it.

[@deanehill9730]

What was the solution ? Thanks for the video.

[@katv4900]

1:06 He showed you. He said the issue with that is it has to be cut to length, and is annoying. But it's the solution.

[@builttolaugh]

So… what would be the solution for a fixture with this exact problem?

[@marvinthemartian4740]

That's why I like being a homeowner in a small city for 2 reasons. 1) we don't have any kind of inspectors. 2) we don't have to go by code cause we funny have a code enforcement manager. So, I would definitely use a bottle trap. Besides, my water goes out the back of my house and empties into the creek. So, no sewer gas

[@manatal4673]

How about a Sink Genie? Thank you for always sharing.

[@mrcryptozoic817]

Build it backwards. Start from a street elbow going tight left (or right) at the wall, put a P trap over there, then over and up to the sink drain? That way you can conceal the P-trap behind a nice looking cover box. I don't see why it matters where the P trap is as long as it drains sink water properly and still seals gasses.

[@Kevscancave]

Very interesting! Thanks for the great explanations!

[@deadbrother5355]

Whats the proper solution?

[@randybb]

A standard trap used in europe :D But the P shaped is better as it doesn't clogh - is basically self cleaning.

[@ericmarinello]

Great video

[@kingssman2]

Never knew these existed. But wouldn't want to use it. That bottle trap looks like it can clog way to easily.

[@chrisdupont1195]

We use them a lot in Europe. They do clog up easily (especially with hairs). But it's really easy to clean. The bottom part can be unscrewed and can be cleaned and put back in 5 minutes.

[@samtheoutdoor]

Yes they often do clog. But they're also easy to clean as well by unscrewing the cup at the bottom. Most rubbish sit there

[@Engineer9736]

In a toilet sink almost no one ever puts mess down the drain that can clog it. Who’s going to put their hair in a sink, or other solid things? It’s just water and soap. I’ve never had to clean out a bottle trap in my life while almost every house has them here in Europe.

[@BigRW]

@@Engineer9736 Where do you shave? In the shower?

[@luisr8360]

Yes they clug easy They look pretty but thats it. If you don't have basic knowledge on using hand tools then don't use this bottle trap. Just like the wall mount toilets they look pretty but have weak flushing.

[@weddingdjMN]

I was waiting for the solution to the problem. Did I miss it? 😢

[@javiergalvan242]

Great item and tip! Another great video guys! 👍

[@imark7777777]

Interesting because I've seen them occasionally and I'm surprised they haven't been "trapped".

[@RaidPerspective]

What does This Old House think of Sink Twice for toilet tanks? Seems like it would accommodate the need without issue.

[@johndoe6032]

I used those in Japan and thought it would be perfect for my tiny downstairs bathroom, but I think most people wouldn’t have a clue how to use them.

[@Mr.Pop0]

@@johndoe6032 You mean use wash your hands in the toilet?

[@thejpkotor]

I’ve found they’re kind of a novelty and not very practical.

[@RaidPerspective]

@@Mr.Pop0 they are faucets that run off the water used to fill the toilet tank. Directly after flushing that water comes out of a faucet and goes into the tank which you can intercept and wash your hands

[@babeksaber2702]

Very Useful...thx

[@Sparky-ww5re]

interesting. Never knew these existed. But it sorta resembles a drum trap, most folks probably never seen or heard of these either unless they are in a house that more than 70 years old. I've seen two drum traps in my lifetime, so far. In a duplex built in 1946, and in a craftsman bungalow built in 1927, both instances used with a clawfoot bathtub. in the duplex the tub and sink were near each other. the toilet at the far end, so perhaps the sink also drained into the drum trap? The clean out plug was in front of the sink and beside the tub.

[@SteveAgl62]

In europe we always use bottle traps, metal or plastic, if u need to clean take a minute to open it, and w are get dead or poisoned by gas all the time LOL

[@thesufiman7764]

What was the cost of the equipment and installation for this system?

[@brendanlavigne2080]

Those bottle traps remind me of something about the old drum traps. Difficult to snake/unclog and not self scouring.

[@Brian77766]

You simply unscrew the bottom section and remove the clog, screw it back on. Why would you ever need to snake it? It's not an S trap. The USA needs to get with the rest of the world. It's a bit like the combi boilers we're all using, you call them instantaneous water heaters, you're only 30 years too late. Our combination boilers heat central heating water and provide instant hot water.

[@kamenneikoo7854]

Except you can easily open the bottom and empty them or just unscrew the whole thing by hand and deep clean it

[@Farm_fab]

What if you have the sink, and can't get a variance?

[@ianbutler1983]

Don't ask, it is your house, useless bureaucrats can go to hell, as far as I'm concerned.

[@horza3106]

Are bottle traps illegal in the UK?

[@EppingForest304]

Bottle traps are extremely common in the UK 🇬🇧 never seen one that has rotted!

[@themoy08]

to everyone saying that their bottle traps work fine and require a little maintenance. That is fine I'm sure they do but you severely underestimate the average person's laziness and/or lack of handiness to perform the minimal maintenance.

[@timfischer]

Video leaves me confused... so what's the real answer for this solution? Seems like nothing they presented is both legal and works well.

[@teacherwaseemheight9586]

in Malaysia, this is common, and it's made out of plastic, like RM 10 for everything

[@jasonkilley]

Would seem fine for most powder room applications where you don't have a lot of hair or other things going down the drain but not good for a main bathroom

[@jackpast]

Well now that was different. A no-real-solution TOH

[@katv4900]

He told you. 1:06 You cut to the metal trap to length. If you insist on using a bottle trap, contact your plumbing authority. All of this was in there.

[@Bobherry]

[@5stardave]

How about having the trap behind the wall?

[@chrisrioux]

I’ve been wondering this, too. Or have it in the basement, or anywhere further down the line that’s not visible. What’s the point of having it so close to the sink where it’s unsightly?

[@chatryna]

Bullet proof...that's what I am talking about. Just had a plumber over today. He thought the job was finished. But no, the rainy plumbing is now a slow drip. Is that acceptable in todays world?

It's a ridiculous regulation. Bottle traps work and you can disconnect them really quick to clear blockages. Any corrosion that leads to sewer gas escaping will be immediately noticeable by the smell. I still haven't heard a single satisfying reason why you can't use them! Just a bunch of slippery slope arguments that make nearly zero sense.

“Illegal” means a different thing in Richard’s mind. You can buy bottle traps and use them all you want. No prison, no fines, no nothing. You will not pass code though. Professional plumbers can’t install these and you will have to change it out if you sell the house. If you put in a new addition the inspector will reject it. Once you fix it and put in a traditional trap and get the approval, you can change it back once the inspector leaves.

If your plumbing work fails and floods the house, or you out of code electrical work burns it down, you’re insurance company will thank you because they won’t have to pay a dime. And if someone actually gets injured as a result like getting burned in a fire or just electrocuted by touching an electrical device not properly grounded, you can be sued for negligence. So it’s best to understand that by and large those building codes exist for a reason, and you can think of following them as buying yourself a little insurance from a future accident.
