vent issue


When you add a basement vanity and shower what is the best way to vent those two fixtures? The shower trap and drain are obviously under the slab so do I need to run a wye with a vent pipe coming out of the ground and then tying into main stack 6" above the highest fixture in the house? What if the shower trap is close enough to stack does it still need its own vent? And what about the vanity vent?

Depends on your code, IPC you can run 8 feet trap to vent on a 2 inch line.

The best way is #1) what passes local code and #2) does the job.
The rest is about design values vs budget.

If what you do won't meet/pass the LOCAL codes then nothing else matters.
Not even whether it works (or not) which comes second in importance.

After those two hurdles are crossed...
then you can get into what the owner/designer wants to see or have.

If they're willing to spend enough money...
then something can almost always be worked out.

and the answer was !! you can run 8 feet trap to vent on a 2 inch line. and the second part would require knowing what code your under.

They should have two plumbing code books one for homeowners and one for professional plumbers mine which is for a professional is about 4 inches thick filled with all kind of sectional references along with charts and tables and requirements, cost me about $200 bucks, the homeowners should be 4 inches thick with blank pages with absolutely nothing inside. as so often seen on these DYI sites most DYI' ers have little regard or concern for the right and correct way of doing things.

vent issue


Some years ago I read what I thought was a great little book on plumbing by Max Aulth. In that book he said that a vent must be provided within 48 pipe diameters. I see in this post that a 2 inch line can be vented 96 inches from its trap. That is in line with what Max Aulth said in his book which I first read about 35 years ago.

In other posts on the plumbing forum I see most of you say that a vent must be provided within 5 feet of its trap.

If 48 pipe diameters had worked for many many years, what is the justification for the change, if there is one?

Thank You. Please do not say "Because it is the code" I think we all like to know the physics behind the reasons we are doing things.

This of course assumes that the drainage pipe is at the proper slope of 1/4 inch per foot.

Javilles, If Do it yourselfers had no concern for doing things right, why would they come here and ask for assistance? Why would they not just do it any way they want?

I will freely admit that most posters are way over their heads right out of the gate and should gain some basic knowledge before ever coming here, especially since most come without pictures.

The folks that write the codes are plumbers of course and when plumbing was first introduced to in door and it developed, those plumbers over the years realized that changes could be made with better results the code gets re written because of many factors larger homes more bathrooms larger tub showers etc, size of pipes matter a great deal in venting issues, the problem is that most people misunderstand the true function of a vent, and just a heads up, very soon there will be a no vent system introduced to the plumbing industry figure that.

As for the DYI ers that post here most are good nature d folks looking to go in the right direction with little home improvement job and that's why i spend my time along with all the other professionals that post for the DYI ers giving advise in good will. BUT then you have THAT one person,,glues together two pieces of pipe and thinks that he's mastered the plumbing trade, and in his mind he's now knowledgeable enough to challenge the plumbers,and why would anybody pay a plumber that much money when anybody can do plumbing.. challenges are usually with sarcastic remark on a post or an answer. when i ask a question its for a reason and the reason is to be able to give him or her the most accurate answer to their question. and in my experience people like this usually end up doing things the way they seem fit blowing off the multiple advise in the posts and in doing so the Code gets butchered, who pays,, well may be a new home owner that just bought the mess the other jerk mastered up ,a tenant with nothing but problems. or a plumber that gets a cable caught in the line because it was piped in wrong. i have some sympathy OPPS NONE for this type of DIY person i be leave they deserve every thing they get.

Well, you're right that there'll always be "those" folks who go their own way in spite of any professional advice given here. Nothing to be done about that. It scares me a whole lot more to come across one of them in the electrical forum.

Where I live, a homeowner can legally do plumbing and electrical work on their own home. When we built our log home four years ago, I did the plumbing. It was subject to the same inspections as it would've been had I hired a pro. So what's the problem?
