vent or not to vent

Hello, i understand that every fixture needs to be vented. I am putting in a bathroom in the basement. i have the rough in (12 x 12 box) for the shower with 2" horizontal pvc coming in. This rough in is approximately 24' from the vent running up through the floor, which sits about 16" from the main waste and vent line. My question is this, do i have to run another vent pipe for the shower or is this pipe serving as a vent for the shower already. All of this rough in was done when house was built 3 years ago. Any help on this matter would be greatly appreciated, thanks

You still have to have a vent line off the shower drain. One reason being that if you don't, the trap of the drain will be sucked out and you'll have sewer gases coming back into the shower. Good luck and post back.

also before or after

Also was wondering if the vent should go before the drain in-line or can it go after the drain toward main waste, or does it matter?

Kevin, Have to admit I am a little lost here. If the rough-in was installed when the house was built, it is likely that the vent was also plumbed in. The vent has to go above the drainline (how far above depends on local codes). Example: The shower drain runs back into the wall and probably comes off a drainage tee which goes to the drain and the other part of the tee goes up the wall and then elbows back over to the ventstack or drainline to prevent sucking the water in the trap in the shower out. Hope this helps some.

Majakdragon, I looked at my original post and forgot to mention there was a whirlpool going in also. I can see how i confused you, and myself. Bottom line is the rough in for the shower (12 x 12) opening just needs a trap. The Whirlpool will have it's own vent line running from it's drain line to vent.
(I originally had drawn two vents attaching to drain line for whirlpool, hence the before or after the trap for shower....Sorry. Just want to say thanks for your reply and your time, take care

drainpipe on bathroom sink install

I am replacing a sink and faucet set in my bathroom vanity. Everything has gone well until....I dropped the sink in and the drainpipe extends about 1 inch into the trap pipe. It does not extend into the curve section of the trap. Can I continue as is or do I need to shorten the drain pipe?

Shower/Tub Fixture Replacement

Greetings, We have a 3 knob shower/tub fixture setup, and the hot water was leaking when we bought the house. The knob was being turned tighter and tighter to lessen the leaking and eventually there was a fairly constant stream. (which was running back through the wall and soaking the framing in-between that bathroom and the closet behind it! But that's another story, and it's all dry now.) I removed the plastic/decorative "H" cover to get at the screw behind the knob and the screw head sheared and fell off at the sight of the phillips head! Both the hot and cold had to be drilled out to get the knobs off, and only then could the difficult job of getting the stems out begin. There was quite a bit of deposit built up on all three, and the hot water side was obviously the most difficult to get off. So, we have all three removed and my question is what to do now? I've read through these forums today, so I'm much more familiar than I was about what I'm doing at all. I'm assuming I removed the 'stems' and that the 'seats' should theoretically be in there still, if I use a flashlight to see them. The hot water side should be damaged, which was causing that leaking in the first place. (?) Now the stems are broken because I had to drill to get them off. (?) The footprint of the current setup is 11 inches, whereas most new sets you buy at Home Depot and the like are 8 or 9 inches, so we've decided to try and just replace and use what we have. Have I entered the world of custom plumbing? I assume I need to buy new seats, stems and knobs/fixtures to go on the outsides of them. Is this something that is easy to come by? Most people at stores in our area only know how to sell you a box including what is behind the wall, which in our case is older, but very heavy duty and in fine shape! As I said, my search got easier from reading this forum today, but do I have the right of it? Is my terminology OK? Are the stems a standard size/type? Will I need to buy all these individually? Thank you very much in advance if anyone has time to read through all this! Craig Hatfield
