Moving soil stack

Hi
Am moving my soil stack from back of house to front due to bathroom relocation.
Have removed old stack and cut UG pipe approx 300mm below ground. Plan to erect new stack. At bottom of this use UG rest bend. UG pipe will then travel horizontal (ish) for 4m.

I then need to turn it at right angles to go downwards to join up to old UG pipe. Can I use another 87.5 rest bend but effectively upside down? Or do I need to install an inspection chamber or rodding access point?

The existing UG then continues down about 6 foot where it finally bends and heads towards manhole/inspection chamber which is approx 3m away. Final invert is about 7+ foot - hence I don't want to have to replace all UG pipe.

Can anyone advise here, please?

Rather than dive down at 90 degrees, you should go down at 45 degrees and then level off with a further 45 degree bend when you get down to the level of the existing pipework.

Thanks Tony
Others on another site seemed to say that I had to have an inspection chamber for all change of direction. I much prefer your answer. I guess its all down to the BCO in the end but as I hope oneday to build a garage over it one day, don't really want an inspection chamber.

Thanks again

Ian

Would think about rodding eyes or some form of access at change of direction though - large masses changing direction can get stuck..... I'm sure you can imagine the rest!

IF you are going to build over the bend, you may want to make it a junction and continue the other branch out to somewhere you can rod from in the future.
