Hey Vince,
25$ over at E-Bay for a 2"Mini-Vent. Studor Vents are manufactured just north of me up in Clearwater, Fl. Cheers, Tom

Good morning Tom, I purchased the 2" mini vent yesterday. It was off Ebay, thanks for the heads up. It probably won't be in until the middle of next week. I was wondering, if I could get an idea on the shower drain until the vent arrives. If not, I'll wait until the vent is delivered. :cool:

Good morning Vince,

What is it you wish to know about the shower drain? If it's connected to the lavatory drain then it will be wet vented by the lavatory vent. Regards, Tom

Thanks Tom, believe it or not I am at work right now. But I will send, of couse, another photo of the drain. It is too high with the 2 inch drain pipe. So, if you or anyone can give me an expert opinion on it, I will be happy. If, there's nothing else, then I will move on.

This is the picture that I had promised earlier. I also understand from another post that Tom is entertaining tonight :D So, if anyone is willing to jump in and assist me I would really appreciate it. The shower drain that I have goes over the 2 inch pipe that's shown. What I'm trying to do is have the shower drain even with the shower pan. The bottom drain is a 3 or 4 inch drain, I believe it is a 4 inch drain. My thoughts are that I could cut the reducer or the drain pipe to lower the 2 inch pipe. Even if I cut the 2 inch pipe down to the base, I'm still too high for the pan. If anyone has any suggestions, I'm listening. :o

Hi Vince,

My entertainment's doing our dinner dishes so I have a little time to look at your picture. I don't know what that is but I know what it isn't. It isn't a shower raiser. For one thing it hasn't a trap, for another it's connected to what looks like a branch off the sewer main it could be a vent or the plumber could have stubbed up for a shower and left it to you to run a ventfor the shower. But why the increase to a much larger pipe size when all he would have needed was 2" all the way. Very strainge. At first glance it looks like a typical closet stub-up but then it chokes down from 4" to 2" and I can't see the first reason for that. It just plain doesn't make good plumbing sense. The only way I can think of a reason for the abortion like the one you pictured is the plumber screwed the pooch real bad and roughed in for two toilets. When he saw his mistake, PVC being impossible to take apart or change, he reduced it down from the closet bend to 2" and left you with a mystery.
You can make that a shower if cut it back under the floor and reduce to 2" there. Then you can roll up a 2 X 1 1/2 wye or drainage tee and take off a vent. Continue on with a 2" trap and raiser to where ever you wlsh to place the shower. Vince, you got my best guess on this one. She's done with dishes now. Seeee you! Tom

Thanks Tom, this stuff must be in your blood because there's no way I'm leaving my entertainment. :D I've read and reread what you said and now I'm going to think about what you're trying to tell me. I was lost after "cut it back under the floor and reduce to 2" there". So, I'm going to do a little more research on the other parts you have listed. Hey, I'm a little slow with the jargon, but I'll eventually understand.

I'm ready to purchase the items you mentioned.

1 4x2 reducer
1 2x 1 1/2" wye
1 2" p trap
? is the raiser part of the P trap.

The 4 inch pipe will be reduced down to the 2" pipe with the reducer, from the reducer the wye will connect to it. Then a 2 inch pipe extends from there with the trap and raiser. Where I'm lost is what comes out of the 1x 1/2 wye. Just trying to get a handle on this. :confused:

I hope I'm on the right track. There are two more pictures I'm uploading the shower pipe picture is after the wye. The 3" inch pipe is reduced to a 2" inch, then extended with a 2 inch pipe to a 2 inch trap. This a dry fit before I permanently install.

Hey Vince,


Both pictures look great, (the trap raiser is the piece that comes up out of the trap) With one huge omission.
Did you miss the part where I said it must be vented?
"Then you can roll up a 2 X 1 1/2 wye or drainage tee and take off a vent.

The wye will install any where on the 2" drain line and a 1 1/2" vent will extend under the slab to a wall where it will go up the wall and out the roof.
Another way would be to bring it up in a wall a few feet and terminate it with a "cheater vent". A cheater vent is a spring loaded mechanical vent that will take the place of a roof vent. Your layout looks good except that it MUST be vented. If you wish to know more about cheater vents just ask. Regards, Tom

Thanks Tom, I was trying to find the original roughin pictures, but will keep looking. My question on the last picture "shower pipe" There is a wye with a 1 1/2 inch that connects under the slab going over to the wetbar that will have a cheater vent on it. Do I have to vent each one separately or can they share the same vent line? Remember, I purchased the cheater vent for the wetbar. :confused:

Hey Vince,

I have the rough in pictures saved to disk. If you extend the 2"PVC up from the wet bar you may loop the 1 1/2" vent of the shower over to it and tee into that line for both vents using the Studor Vent. Regards, Tom

I was hoping you would say that. Thank you. :D

Good morning Tom, I understand that I'm not the only person that's asking for your expertise. So, I went back to see if I could find the original pictures for the roughin and I found one where I could edit it for clarification. I'm hoping this will help me in moving forward with finishing the project. My drawing skills are not that great, but should help. I'm attaching another picture. I guess where I'm most concern is the wye from the shower over to where the wet bar will be with the cheater vent. Then the 3 inch vent pipe from the basement toilet that ties into the bathroom from upstairs. Finally, the lavatory, where does the venting goes for the lavatory. I'm not sure about vent revent of lavatory. I'm hoping that this will speed things up, so you can answer other posters questions.

Hey Vince,

The picture came out so dark that I couldn't read your notes. Can you lighten it and resend? What In did see worries me. In my last post I mentioned the 1 1`/2" shower vent , but what I see in the picture is a vent off the toilet that didn't need one and a shower that's unvented that has to have one. Remember I said you would have to cut in a 2 X 1 1/2" wye that 's rolled up on a 45 degree angle so it doesn't clog and line a street 45 out of the wye to the wall and up to a cheater vent where the lav and bar sink can revent back into. Don't forget! Configure the vent fittings so that the flow runs from the roof to the base of the vent. If this's a picture of your earlier work beforeyou cut in the shower vent please send me a picture of what you're done so far. Regards. Tom

I'm sorry Tom, I wasn't trying to confuse you. I was trying to show the original roughin with the added work since the beginning roughin. I don't have a picture of the wye that comes out from the shower going over to the wetbar. Maybe I'm not explaining it better, If you have a picture or a diagram maybe I can better understand. Ok, I'm sending this picture that I sent earlier, If there's a wye, that connects over to the wetbar that has a cheater vent on it, would that be OK. I think you want me to put the 2X1 1/2 wye on that 2 inch pipe to go over to the wet bar. But what if the 2 x 1 1/2 wye is connected to the 3 inch pipe where it was reduced to a 2x 1 1/2 inch wye that goes over to the wet bar. If, I have confused further, then let's forget about that part and concentrate on the lavatory next.
thanks,
vince

Hey Vince,

"If there's a wye, that connects over to the wetbar that has a cheater vent on it, would that be ok.
I think you want me to put the 2X1 1/2 wye on that 2 inch pipe to go over to the wet bar. "
I want you to do what I asked you to do and that is to cut in a 2 X 1 1/2" wye that 's rolled up on a 45 degree angle so it doesn't clog in the shower drain and line a street 45 out of the wye to the wall and up to a cheater vent where the lav and bar sink can revent back into. Don't forget! Configure the vent fittings so that the flow runs from the roof to the base of the vent.

But what if the 2 x 1 1/2 wye is connected to the 3 inch pipe where it was reduced to a 2x 1 1/2 inch wye that goes over to the wet bar. If, I have confused further, then let's forget about that part and concentrate on the lavatory next.
Now you've managed to completely confuse me. Let's see. A 2X 1 1/2" wye
that connects to a 3" pipe? (Nice trick if you can do it.) Did you mean a 3 X 3 X 1 1/2" wye that was reduced to a 2 X 1 1/2" wye, (another neat trick).
Let's forget about that before I get a headache teying to figure it out.

What's your question with the lavatory? You can put the cheater vent on any fixture that you choose. Then revent the other fixtures back to it. The shower vent doesn't have to run over next to any thing . Whatever you connect the cheater vent to becomes the vent for the group. The rest then become revents. We ARE talking vents and not drainage aren't we? Yagot my head spinning Vince. I'm going to take a break and walk da dawg. Tpm

Sorry Tom, didn't mean to give you a headache. I think I'm going to stop where I'm at. Thanks for the help.
Vince

Hey Vince,

"Sorry Tom, didn't mean to give you a headache. I think I'm going to stop where I'm at. Thanks for the help.

Stop what? Your project or stop asking questions? You're on the right track, all your project needs is a little "tweeking". My headachs's gone so if you have more questions I'm still here. Have a great Sunday! Tom
