Rest bend tee

[willbish]

Is there such a fitting as rest bend tee?

 

I'm planning an internal stack so will need a rest bend underground for support.

 

Was hoping to 'pick up' the stack on another waste run using a tee at the base.

 

Alternative would be another run to the inspection chamber but its going to be crowded there.

That's the right thing for the bottom of a stack but I don't think there is one with a T- joint on it as well. 

 

Normally if you have several stacks you use one of those rest bends (aka large radius bend) at the bottom of each stack to send the waste outside, then run a pipe along the outside to connect up all the stacks and feed them to the sewer. Usually each connection will have a manhole on it.

 

You can have a large diameter (eg 110mm) horizontal pipe connecting two stacks together above the rest bend but I don't think there is one bit of plastic that does both bend and T-junction. Would be a bit unwise as you wouldn't be able to access it if there was a problem.

 

edit: I think any connection into the stack above the rest bend has to be 450mm above the bottom of the rest bend.

As per @Temp states - take them outside individually and then join them.

Ah okay if there's no such fitting then it'll have to be another seperate run to the I/C.

 

Thanks!

BCO wouldn't be happy with a foul T and no access

Do you mean access via an inspection chamber or access via the stack?

We've put inspection chambers where soil runs join.  You've got to be able to access them.  We also have access to the base of each stack.
