Odd underground pipe? Can anyone identify?

[dilalio]

one for the drainage guys...

Should have taken a couple of pics yesterday - will do today.

Dug a hole in front of iron soil stack to investigate getting a connection to a ground floor wc.

Apart from discovering a flexi pan connector below ground going from iron to clay , we also uncovered an odd section of clay pipe about 4’ long. It’s torpedo shaped and flares from about 7” to 9” in the middle and then back down to 7” where it connects into a female socket of the next section of clay downstream (due to access we haven’t exposed any more of that section).

We need to get an IC in right where the torpedo bit is and still make a good connection onto the outflow part of this pipe, which obviously has a diminishing diameter!

Any ideas on what this odd section is, why it was used and how we can get onto it? Everything upstream can be replaced with new 4/5” underground.

Many thanks for any shedding of light

It's not a bodged up bit of 6" over the 4" is it?

I'm looking forward to the pictures x x x

Wtf!!!

Some type of odd 4-6" reducer? Is that the only section like it, or can you see if downstream is also like it?

Come on now, can you not recognise a power bulge when you see it. ?

Maybe it has some effect on the rate of flow into the bend.

It's a 4-6" schlong.

The flexi seal adaptor couplings with a jubilee clip come in a variety of sizes. Sure you will be able to find one that fits.

Maybe it’s just normal 4” pipe that swelled after someone flushed the remains of a very hot curry

That wooden shovel looks hard work!!

Everything sub-terra is bloody hard work! ... well it was for my mate Bobby Lee

It's a 4" to 6" increaser - cuz that's how the flow goes

Don’t I think I’ve told the story here before... a mate of mine once told a stroppy customer that his toilet kept blocking because the pipe was 4” and the customer had a 6” ar$€hole

But it tapers back down again Nige!
That’s what we can’t fathom!

Does it taper down @ the bottom of the picture - I thought it was a bend downwards into the mud
