Shower without a p-trap

JasonG's picture

Our shower does not have a p- or s- trap - it is connected directly to the sewer pipe in the basement, so we oftem have sewer gas smells in the bathroom. Can I install a p-trap anywhere along the "horizontal" run of pipe between the shower drain and sewer stack? It would be most accessible to install and service about 2 feet from the tub drain. Will this be a problem?

Also, I understand that by not peeing in the shower, I won't need a trap! I figured that response would be coming, though.

Thanks,
Jason

From a practical viewpoint (that is, keeping sewer gases from coming out the line), yes. I don't know about code.

I hope you're joking. The gases don't just come from what you put down the shower drain.

grpphoto: Good post, any trap is better than none, but down stream is usually against code, I have to limit my posts because on BREAKTIME for some reason I can't paragraph a sentence. "May the force be with you"

Thanks for the trapguard link - I will look into that further.

And yes, I was kidding about peeing in the shower - I know where the gasses are coming from - just trying to head off comments about "pee-traps" and smelly bathrooms.

According to the JLC Field Guide traps should be as close as possible but code officials will often allow up to 2 feet to avoid framings obstacles.

Don't forget the vent! I have a house that a guy took out the vent on the 1st floor tub drain and allowed the tub to drain to the vent of the vanity in the basement.


When you took a shower on the first floor, the traps in the basement would burp....and when the laundry machine filled the work tub, it would burp the trap on the first floor....stinky little mess.


But I resolved it on my recent bath redo by providing adequate vents.....now everything goes down very quickly!

JasonG: I think that you responded to the wrong post, I did not give a link to a Thapguard, I think that it is a bad idea on a shower and probably against code. Most of these type of devices are for floor drains that have a trap in them, I don't see where you can use them in lieu of the trap, luck.

ALL FIXTURES NEED A TRAP!! The trap needs to be as close to the drain as possible, it should not be run 2ft. downstream. Peeing in the shower is not the prob. its what is comming up thru. the sewer system that could cause you a major health issue!, fix this as fast as possible!

Please people, give the guy a break.  Or lighten-up, try reading the guys post, and perhaps think.  The guy was trying to preempt one of you guys making a crack, so often done here for humor and with good affect, using a pun about peeing/urinating in a P-trap.  A trap to caught Pee, get it?

Thanks DoRight.  We need more kind and sensitive types around here.  There are way too many meanies... ;-)

Matt, I do it at my own peril.  Typically, it elicits more bashing and personal attacks as the high-school clicks engage to defend one of their own.  I find human nature interesting.  But, in the end I just plain feel bad for new, well intentioned, postings getting rip for no reason.  I like to let them know that not everyone is ready to cut them a new .....

A new.... sewer vent? < G >

I agree with you that acerbic comments should be reserved for people known to deserve then.

Thanks for the advice. I installed a proper p-trap this weekend. Beams prevented installation from the basement, but I was able to cutthrough a closet wall and not have much trouble.

Also thanks for the confessions about peeing in the shower. Luckily my toilet does a remarkable job at disposing of bodily waste and my wife and kids don't have to bathe in it!

DoRight: I did get the point, but running into some of the most ridiculous advice that was given to people over the years, I have to err on the safe side. BTW, I think that most people will pee in the shower, I bez one of them.

Two words for you guys:


"EW!  Eeeeeeewwww!"


 


I really don't like bathing in toilets, if i have a say in the matter.  Yes, I know that pee is sanitary, it even has antibiotic qualities.  Still don't like standing in someone's urinal.

You might want to look at these.

They are a waterless, mechanical trap system.

Have you had good luck with these?

(post #77161, reply #8 of 24)

I have not used one. Just remember seeing them in the new product news.

I'll second the TrapGuard.

I have a basement shower that likely has no trap before it hits the sewer line, and was putting out some nasty smelling air. I put one of these in and, presto, no more foul odors. Best $20 I spent in a long time.

Do it right- put in a proper p-trap somewhere in the line. I doubt trap-guard meets code for this application.(it is meant for a floor trap).
