How to prevent chamber blocking

[nickhart]

After some advice please, my waste chamber clogs up about once a month, please see picture.

i put the chamber there because the pipe turns 90 degrees right under the new extension also there's another pipe to the rain water down pipe.

Please help do it need to move the chamber? And where?

The manhole

The manhole

Can you draw the waste outlet and run ?

Can you show the manhole clear? Does the gully connection have a sufficient fall?

In my opinion the manhole is to close to the
extension waste solids will be traveling a quite a rate through that soil pipe a nice slow sweeping bend at the base of the soil stack then into at least 1.5 m of straight pipe before entering the manhole to slow down the splatter effect of solids and toilet paper this is what your experiencing causing blockage rodding access is a must aswell at it base of the soil stack .
