New Question on DWV for new bathroom

can you provide me some insight my new toilet main/vent run as shown in the picture.

when I connect a 3" horizontal run to a 3" vertical main is what I shown in the pic correct?

At the bottom of the main shown in the pic do I need to provide a cleanout and do I have to use a long 90 to go from vertical to horizontal.

Also as shown in the pic how do I connect a drain to the vertical/horizontal drain..

thank you a million times for any help

Looking at the first picture the toilet rough appears to be fine. On the 3" going up to tie into the rest of the bath I'd just take it up and make the turn with 2- 3" 45". I would place a cleanout tee (testtee) about 18" to 24" off the floor below the wye shown. Either use long sweep 90"s or 45"s to make the turns under slab.

I have to say that is a lot of venting, down here there would only be 1 vent for that entire bath.

again I appreciate your help. And yes in MInnesota I need to have a seperate vent for each fixture.

Also as shown in the 2nd pic, how do I connect the drain into the main once it turns from it vertical run to the horizontal run under the slab.

If its on the vertical section, a santee is acceptable. Otherwise you'll need a wye and bend if you intend on connecting into the horizontal run.

I some what understand what yu are saying. But since my main is running vertical and then horizontal below the slab I will need a long 90 or x2 45. So how do I satisfy that requirment along with adding the floor drain with a 2" out into the horizontal part of the run?

 

[Iminaquagmire]

If you want your floor drain where it is in the picture, use a wye and 1/8 bend instead of the long sweep 90 or 45's. Then off the back, use a reducer and connect your floor drain. If you can bring your stack out a little ways to bring it in line with the run under the slab, it would be even better still. If you want your floor drain off to the side, use the long sweep 90 and then put a 4x4x2 wye and 1/8 bend on the horizontal run. Attach your floor drain to that like in the second pic.

The ac/furnace that is next to the drain will of course be draining into the floor drain that we will be installing. Would we still need a primer?

 

[SeattleSean]

Can't you run vents below slab as long as they are not truely horizontal and slope 1/4" per foot. That what I was going to run for mine. Is this correct?

 

[Jadnashua]

a short section of the vent may end up horizontal for something like a shower drain, but basically, you need the vent to turn up as soon as possible. And, you could never connect multiple vents underneath the slab, only above the flood plane of the traps they serve.

I know nhmaster is always correcting drawings that have vents that look horizantal but if they branch out at 45 degrees I think its fine, of course keeping 1/4" per foot at that 45 degree angle.

Need addtional assistance for drain and venting

The plumbing drawing shows the drain and venting for the shower and tub. Minnesota code requires a seperate vent leaving each fixture ( as shown in the plumbing draft)

I have a question on how to run the vents and drain for the shower and tub because of space limitation I have as shown in the digtial picture.

If I was to use a san tee as shown in the draft and a long 90* to make the phyical drain run I would not have the height needed ( the san tee and and drain is of course below the floor above)
The second picture is below shot

That piece that says to vertical vent is wrong. It can not run horizontal.

That piece that says to vertical vent is wrong. It can not run horizontal.

As the red lines in the pic show the space I have to work with (7 Inches between red lines) -how do I make the connection correctly. I kind of thought that since I first ran my vent horizontal and then vertical that it would be wrong.

But since I dont have enough room to run the plumbing as shown in the drawning what are my options?

Thank You

Is the drain going to run over to where the vent can go vertical? If so, then just make the vent go vertical there. The distance from the trap to the vent depends on the size of the drain line...I think for 1.5" pipe you have about 5'. There must be a vent before the drain connectes to another drain.
