Best way to add rodding point.

[Sounduser]

Hi. 

 

I want to add a downstairs toilet. 

 

Which would mean adding a swept 90° turn on the existing underground pipe work.

 

I was wondering is there a specific product that would be like a 110mm swept T with scope to add a rodding cover at ground level? 

 

Or do I need to add a larger diameter underground inspection chamber? 

 

Any advice would be great.

You need to add a better picture than that, bit more detail draw whole house and new toilet location. 

From a rough guess you will have to put a new inspection chamber at the location you want to have that junction. 

You cannot put a 90 on it’s side underground without providing access for future unblocking duties.

I was thinking something like above.

If I am reading that right then you want to cut into the pipe that runs from next door..? If so, you need your sewage providers permission to connect as that isn’t your pipe to connect to and would need to put a manhole along with a secondary IC on your side of the pipework near the new soil stack. 
 

All of that is notifiable works and requires building regulations approval.

I've got a Severn Trent build over permission. And building control knows what I want to do. They're going to check when I'm finished.

OK so build over and connection are two very different things ! The main run you want to connect to isn't yours, and you can't connect without permission. You need to have a contractor with connection permission do it, or follow the guidance very carefully and then get ST to inspect it before it is covered over.

I called Severn Trent last week. The lady said they don't inspect pipes less that 150mm

 

The digger man chipped a pipe. So I've already repaired it. She said I've got to have a CCTV camera before and after by a third party. Or replace the whole pipe and then have an inspection after. 

 

If the pipe in the garden isn't mine, then why do they keep trying to sell me insurance for it.

Perhaps I missunderstand but that sounds like a regular inspection chamber base..

Thanks for the replies. I want the smallest possible.

In the link it's a Marley 250mm 

But yeah.

You cannot use a 250mm IC to connect to a lateral foul drain that is owned by Severn Trent.
 

Firstly, they are for plastic pipe and you have clay.

Secondly, any connection is required by law to meet Sections 106 to 109 of the Water Industry Act 1991. That requires any chamber to be built to meet the Design and Construction Guidance as detailed for sewer connection and construction. 

Thirdly, if you block or disrupt the flow to the upstream properties and cause any issues you will be legally liable for damage caused and the charges from ST for resolution can and will run to thousands. 

I really suggest you get this done by a contractor who has the appropriate certification and insurance to do such a job. It isn’t a DIY job, and it can go horribly wrong.
