The contractor who is remodeling my kitchen installed a new sink. The drain pipe goes under the floor through the crawl space. He said there is enough height to the drainage, so there is no need to install a vent. I have read that you need to install a studor vent if it's hard to connect to the house main vent. Is the contractor correct?

Well, it needs some kind of vent -- And if venting through the roof or tying in to an existing vent stack isn't feasible, then it should have a Studor or Oatey AAV.

Your contractor has built you a illegal "S" trap. Chapter 14 Section 1409.2 of The Standard Plumbing Code tells me that each trapped fixture shall be vented. When you add that to Chapter 7,section 703.5 that prohibits "S" traps you have a contractor that should be sent back to plumbing school to learn basic plumbing 101. Since it's too late to add a outside vent a Studor vent's better then no vent at all. Good luck, Tom

It may or may not be an s-trap, Tom.

Remember the guy from Canada several months ago who had the trap for his kitchen sink below the floor joists with the standpipe coming up through the bottom of the sink cabinet?

It was a hokie set-up to be sure, but it wasn't an s-trap.

You're stretching for this one groowler. There should be no good reason a plumber would increase the tail piece length to drop under the floor to a "P" trap when he could cut in a sanitary tee at the correct height. Hey! If it walks like a "S" trap and quacks like a "S" trap then that's the way I see it.

If it is an ''S'' trap, I wonder if this guy follows the electrical code as closely as the plumbing code.

You're stretching for this one growler.

No, I'm not -- Just because you've never seen it doesn't mean it isn't done.

There is if the practice is accepted by the local authority, as it was in this example.

Look, neither you or myself would do such a thing, but that doesn't mean it isn't done and done in compliance with local code and the approval of the local authority.

Get off your high horse and stop acting as though the code you learned is the only code in use.

As you can see, the example I refer to above isn't an "S" trap.

As I've stated, you're stretching for this one. It may be within code but it's not common practice.
Of coures there are exceptions and of course it's done. And don't tell me that I'[ve never dropped a trap under the floor line. I remember having to trap a second floor shower that way. Back the hell off with the sarcastic remarks.

Get off your high horse and stop acting as though the code you learned is the only code in use.

I never said that picking up a trap with a extra long raiser was against code.
The Op said the pipe ran down beneath the floor line. I repeat, " If it walks like a " If it walks like a " trap and quacks like a " trap and quacks like a " trap then that's the way I see it.. "
Sure it could have a trap under the floor line but the OP described a " trap then that's the way I see it.." trap set up. So don't come in all rightious and belittle the obvious. Putting a trap under the floor when it belongs 18" above said floor is not usual plumbing practice so you climb down off your high horse. You're not the only plumber on this page with field experience. Having said that I consider you a competent mechanic who just comes off a bit huffy at times. Regards, Tom

And I'm telling you, again, that I'm not.

Furthermore -- I supported my position, which beats the heck out of anything you've had to say on the topic.

It may be within code but it's not common practice.

If it's within code, then how can it not be common practice?

Fer crying out loud, Tom, how can you be this thick?

Y'know, Tom, if you want to run this board as your own personal dictatorship -- Then have at it, just don't expect me to kiss your butt every time you fly off the handle.

Go back and read my post again. You've missed the point. DROPPING A SINK TRAP BENEATH THE FLOOR LINE'S NOTCOMMON PRACTICE.
And for petes sake, lose the attitude! Tom

[iamgrowler]

Go back and read my post again.

Not only did I read and re-read it several times, I saved and archived it for the next time you so flippantly accuse me of "stretching it".

I'm not just good at what I do, Tom, I'm *VERY* good.

You've missed the point. DROPPING A SINK TRAP BENEATH THE FLOOR LINE'S NOTCOMMON PRACTICE.

No, I didn't miss the point at all.

I've said it before and I'll say it again -- Codes differ from locale to locale.

If it is code in only one municipality, it is still common practice in that municipality.

Period.

Frankly, you need to get it through that thick skull of yours that what passes for code in your lil' fiefdom isn't necessarily what passes for code outside of your lil' fiefdom.

Period.

And for petes sake, lose the attitude!

Fighting for what is right and pointing out that there is more ways than one to skin a cat isn't "attitude", Tom.

Look, if you think my being an advocate for a differing point of view is about "attitude", then petition the moderators to ban my posts -- Otherwise, back the hell off.

[speedball1]

back the hell off.

Nio! You back the hell off. Hey! You can install all the traps you wish with a 6' raiser if you believe it's "common practice".

Talk about thick. How did code creep into this? I never said that a extra long raiser was against code. Hell! I've had to install one or two that way myself. What I said was a tailpiece that runs through the floor indicates a "S" trap and you jumped all over it like you were the only expert on this page with field experience. Get off your high horse and stop acting like your "The Defender of The Code". Of course I reealize codes differ from area to area. We have to license ourselves to work out on the each of the islands and keys that are off our coast. Don't tell me about different codes. Ban you? For what? Being pompous, opinionated and argumantative? Nah!
I'll just let your attitude speak for itself.

I'm not just good at what I do, Tom, I'm *VERY* good.

On behalf of the other experts we feel honored to have such a humble man on tap to criticize and correct out posts. Here's a big hug to start your day! Let me end this post with a familiar refrain. "And for petes sake, lose the attitude!!"
