90 Degree Turn Not Using An Inspection Chamber

[MortarThePoint]

I need to turn 90 degrees from my bottle gully without using an inspection chamber for the turn and see two main options for it:

   (a) use a 45 degree bend on the bottle gully and then a second 45 bend before the long pipe run (~5m).

   (b) use a rest bend either directly on the bottle gully or after a coupler and short length of pipe (will depend on trench position).

Both should be roddable since the bottle gully can be rodded and there is an Inspection Chamber (I.C.) at the end of the long pipe (~5m). Can't you rod through a rest bend? If so, I lean towards option (b). (b) is also cheaper as I have a spare rest bend. What do others think?

 

For full disclosure, the I.C. is a 4D960 shallow one and has two S/S 45 bends on it as it is at the corner of the house so the pipe turns. All these pipes will be paved over.

Defo overkill to have an IC to do this. 
 

Option B is a plenty good enough (normal) solution, afaic.

You may need the 2x 45° option if there’s a sudden change in levels. 
 

Also, I’m sure most of these square pots drop into a round socket, so you can rotate the pot and the grille stays square to the house.

I'm using a type with a concrete top mould on which I don't think can rotate

2x 45’s may give you more wriggle room then.
