Equal Y junction soil pipe fitting?

[flanagaj]

I am trying to deduce the junction below and how best to do it with 110mm soil pipe.  I want the flow to go in both directions, but didn't want to use an inspection chamber.  It's the pipe layout for a drainage field.

use a 135 junction and shove a 45 in the end of it.

I’ve just installed a TP for a neighbor and had this conversation with BC 

Id check with BC ours wanted an inspection chamber and ours was only top water If yours is foul I wouldn’t consider not using a chamber

Seems strange that they want an IC. The tanks all have internal sampling chambers so unsure why they want one.  Did they give a reason?

The fall on the inspection chamber would be the wrong way. They are designed to flow 3 into one not 1 into 3!

 

It may be the requirement for a rodding point and a place to see if the water is dissipating and the drain is not clogged up.

I have accesses each end of my surface water soakaway for these reasons.

 

I would have offered two Y junctions with the straight on rising to a rodding point.

 

Good luck

You can get a level invert chamber.   The below would work.
