Moving an inspection chamber

[pilsbury]

On looking at where I'm going to build a wall as part of an extension, I have an issue with an inspection chamber. As you can see on the diagram it currently sits in an ideal location at the intersection of the drains.

I intend to extend the kitchen out sideways (level with the kitchen wall) to incorporate the lean to and outbuildings which will at present build over the inspection chamber.

If I just move the inspection chamber straight backwards it will not be at the intersection of the drains thus prevent rodding.

Just for info, drain 2 will likely be removed.

Any ideas?

If this is a public sewer, you will need Severn Trent's permission before moving their pipes and manhole.

I believe this is my private sewer. In my back garden and only my waste going into it.

Need to see the layout before we can offer any further advice.

For some reason I can't upload, jpg or pdf?

Only thing I can suggest is moving the chamber out slightly so its clear of the building, turn the existing drains 90deg inside the new chamber, and then use a slow bend immediately outside the chamber to get the drain back to the existing line. Really cannot avoid a chamber on a 90deg bend, using a 90 deg bend and burying it is a recipe for disaster.

Is an option to cap off the top of the chamber and add in rodding eyes along the runs?

If drain 2 is being removed, then swap the chamber for a bend and rodding eye
