Ive got a bathroom that is located in a way that there is no ability to have a p trap underneath it. Currently flow runs about 5' and then joins to 3" line, the 3" line runs quite a ways along a wall and several other things dump into it. Can I put a p trap and vent in the 3" line to control odor coming up through shower drain? Is there any kind of one way valve that I can put in this line that would allow toilet waste and shower water to flow out but would prevent smell from coming in? Just wanting to have some ideas before having a pro come over. Thanks.

Why can't there be a trap under the shower?

There is no space unless the entire pan were raised up. Hard to explain but not possible to fit anything more than an elbow directly below shower. Any ideas?

Where is the horizontal drain pipe the shower drain would tie into? Under the slab? Where does the toilet drain to? Basically, you can't put a remote trap for the shower or the entire bathroom group.

So can I get some kind of in line flapper valve? I have access to the plumbing, it is above grade. There is a door just below, and not enough space in the floor which is car decking over beams. I am trying to control the sewer gas.

In spite of what you're telling us, there's always some way to do it correctly.

raising the shower up would allow a trap to be fitted below it. but then that trap must be properly vented or you risk having the water syphoned out of the trap when you flush a nearby toilet.
forget about any kind of flapper valve to keep sewer gasses contained.

I found this rather interesting. Was this bathroom added after the house was built. I'm surprised that the plumbing wasn't engineered prior to the construction of the bathroom, allowing more room for such things..... like a vent.
Perhaps a licensed plumber, doing an onsite evaluation can offer you more tangible ways of achieving your goal, within codes.

You do NOT need our ideas. You need a professional plumber AT YOUR HOUSE to install it in a proper way. "Creative fixes" are seldom DIY jobs.

An "inline flapper valve" would create MANY more problems than it would solve, and would not be "legal" for what you are trying to accomplish either.

is it possible to us a running trap? Check your code though cause it could require a cleanout at the trap.

I'm going to post some pictures. Got a link to a running valve? Thanks for the tips. Why is making poop run down hill so complicated?

You asked: "Why is making poop run down hill so complicated?"
Running solids "downhill" is the easy part, just make sure you have smooth flowing runs 1/4" per foot fall all the way down. Meaning quality smooth inside straight pipe, no ups and downs....just 1/4" per ft fall, no sharp turning corners and no humps or restrictions anywhere inside the pipe.
Naturally if you live in an area that has a plumbing code then those rules ought to followed which may also include cleanouts at certain intervals or at some changes in directions, and so on.
Still, that part of "poop running down hill" by itself isn't that complicated.
However if you also wish to be totally sanitary and "safe" as in not having any odors, methane, etc into your house (proper venting prevents that) as well as to have the least amount potential stoppages (check valves in drains tend to produce issues like that) then that makes it more complicated.
It's not rocket science however to do it all "right" is not as easy as just throwing in a drain, a check valve and hoping for the best.

The best "creative fix" would be to hire a licensed plumber,not a handyman .I would think that if you have room for an elbow ,you would have room for a trap.Hard to tell without seeing what you have .JMO
