No hub cast iron Imperfect vent connection

[branimal]

Ok reread Frodo and MrDavids old posts. Sounds like I can buy a p-Trap with a rotatable weir. Is that rotation counted against the 135 degree limit before being required to install a cleanout?

Still don't understand how I'd be able to use a sanitary tee to vent.

 

[frodo]

no, the 135 degrees does not include the p trap

Reread some of frodos and MrDavids posts. A trap with a rotating weir maybe the solution. I'll check my local plumbing shop.

Thanks frodo, I owe you many beers.

 

[branimal]

[branimal]

I've read that ~5 is the limit

diagram showing drain distance from the main stack. Is it possible to implement the santee solution?

Couple questions

1. How close to the ptrap can the sanitary tee be?

2. Is the 90 degree turn of the sanitary tee counted against the 135 degree limitation?

 

[branimal]

Ignore the first question..

 

[frodo]

Ignore the first question..

yes, the tee is an offset

you are allowed 6' from the tee to the weir

using 2'' pipe

 

[branimal]

So if I put a 90 on the bottom of the tee to bounce back to that toilet, I've turned 180 degrees which is greater than the 135 limit.

Look at my pictures . pretty close is okay

After the vent connection to the santee, the drain is no longer the trap arm.
So the 5' max of trap arm is to the vent, not total drain length.

They wye is backwards.
Frodo drawing is what it should be but the vent is going the other way.

Can I use a sanitary tee instead of a tapped santee? Looking at the Charlotte manual, the sweeps seem similar.

 

[branimal]

Ok Here's my new plan for the drains. Does this work? There will be 90s at the bottom of the tees.

Thanks

 

[frodo]

2'' trap arm max length is 5' upc code
and 6'' ipc code

depends on where you live

 

[branimal]

Can I cut off a 1/2" from the bottom of the sanitary tee? I already took an inch off the 90 that attached to the bottom of the santee.

 

[frodo]

do you have room to do this

 

[Mr_David]

Hope this makes sense. leave the shower drain except roll the wye above the trap arm.

David has the answer, he also has the smallest damn picture
