Sorry for the pm but I have some pictures that may be a bit to big for the forum so I figured better to pm you than post and slow down board.

You have provided a lot of help to me so far and I want to run what I am about to do past to you to make sure it all correct.

Below you will find two drawings of the ruff layout of my project. And what I am now going to start ruffing in the plumbing on I just wanted to make sure that the way I have it is going to be OK.

First is a drawing of how I was planning on the drain pipe. Black is 3 inch drain red is 2 inch drain and green is 1 /12 vent I am sure your going to tell me that needs to be 2 inch though.

For the lav and bath 2 inch pipe I planned on dropping it down into the 3 inch drain from the top not sure if this is how I am supposed to do it or if I am supposed to come in on the side of the 3 inch? Any advise you can give me on what fitting to use etc is greatly needed. Still a bit confused on how to vent the toilet can I just take and put in a 3 x3 x2 just under the flange to vent it? Sorry to be such a pain.

Unless local codes call for a individual vent on the toilet it's wet vented by the lavatory vent. Would it be possible to drop the 3" low enough to run the tub drain over it and tie it into the lavatory drain? If you could configure it that way you could get by with one 2" vent off the lav. If not you will have to move the tub vent downstream from the trap. We will get into fittings when the drainage is laid out. Regards, Tom

Also the lav is a pedistal on an exterior wall the wall is a 2 x 6 wall but we live in a area that experiences winter my question on that is should I be concerned about putting the pipes inside this wall about freezing?

This one is of a 3d view of what it would look like in the basement.

Sorry for so many questions just want to make sure I do it right the first time.

I have studied your lay out. If you could possibly lower the main enough to get either the lavatory or the shower drain line over it I can get you by with one vent for the entire group. This will hinge on the elevation of the main under the floor. How it would work is lower the main down enough to slip the 2" shower drain line over it and connect to the lavatory drain where it will be wet vented by it. The lav drain could then 45 down and connect to the main.
This will save you the hassle of installing three vents where one will do.
As I've stated we'll talk fittings when the job gets laid out. Regards, Tom

Yeah I can drop it however far it needs to go that room is nothing but a storage room in the basement is nothing but storage in the firstplace.

OK,

Start at the toilet. From the flange drop the quarter bend low enough to slide the 2" shower drain over the 3" main branch. I have Xed out the drains and vents and have drawn in the new configuration, (see image). If it meets with your approval then we can c began to make a material list. Sound like a plan? Tom

Looks good but is it an issue to have the lav hooking into the shower and the shower vents instead of the Lav.

If you will look on the plan you will see the vent is located off the lavatory and not the shower.
The shower connects into the lavatory drain where it will be wet vented by the lavatory vent. I took your drawing over to paint and attempted to change the background to white so I could draw in changes but I couldn't so this is the best I can do. This is a rough drawing of what I want to do. The shower drain will have to be reconfigured so it enters the lavatorfy drain at a better angle
Is there any chance that you could change the blue background to white on the print?
That way I could scan a master drawing in without the drains so I could do a layout?
Cheers, Tom

The way you have it looks fine I will look to see if I can change the background color when I get home from work. :D

speedball1 · May 9, 2006, 03:52 PM

Thanks,
Works for me. I'm tied up today so it will late afternoon or tonight before I get back to you. Cheers, Tom

Start at the toilet. From the flange drop the quarter bend low enough to slide the 2" shower drain over the 3" toilet branch. You may then 45 over to a 2" combination wye and 1/8th bend on the lavatory drain to connect. This configuration will do away with 2 vents and the need to revent them,(see image). The shower and the toilet will be wet vented by the lavatory vert. More questions? I'm as close as a click.
