My wife asked me to clean the wheelie bin at the weekend. A short while later I had lots of mucky water in the bin which I then poured down one of the drains at the bottom of a gutter downpipe. I then found the drain was blocked at or beyond the U bend.
A little later I had dug it all out
I need to raise the drain itself as part of my patio works. Is the plastic drainage pie you get now compatible with this china pipe? Or do I need a conversion piece?

Something like this: https://www.thesafetysupplycompany.co.uk/p/9576673... (but check the dimensions!)
Assuming the glazed rest bend is now clear and not damaged, rather than remove it and reposition it/replace it, sit one of these,
atop it (it should be wide enough not to fall down the hole) and mortar it into place. You can then slide one of these,
into it at a height to suit, you can get gulley trap risers if it’s not tall enough.

Thanks all.
The U bend isn’t clear yet as it’s all cemented together and I didn’t have time to risk taking it all apart, cleaning it and putting it back together, especially as there was nowhere open to buy bits if anything broke! So it’s this weekends job.
It’s going to be a bigger job as I know the other end of the drain where it emerges in to a manhole is blocked. So I am going to use this opportunity to find out how far the blockage goes from the other end. I am replacing the patio that’s over it all so want to clear it before I start!

I will be very impressed if you can separate the rest bend from the pipe without damaging it!
Managed to get it all apart without breaking it And found it’s blocked right round the U bend and down in to the main run of the drain which is also blocked. Used an attachment on the Karcher to try and clear it but failed, potentially not helped by the need to go in upstream of the blockage.
No real idea where the drains go, there’s a manhole in my neighbours garden and the three entries in to that are blocked, the one that is most likely mine is the most solidly blocked.
However it’s possible none are mine.
Problem is the main pipe is a metre deep and under the patio. So next plan is to get neighbour with a mini digger in and either dig right down uncover lots of the pipe to see where it goes then try and clear it, or just put a new drain in and drain it in to the ditch at the end of the garden which I guess is where it’s meant to go anyway.
We have something similar. After much investigation I have found they are not so much as blocked ,they just lead to nowhere. They were originally put in as soakaways,rather than fully connected to a proper drain.
Over time the mud has just creaped further back up the pipe . In my case clearing them is pointless and impossible as I just drag more mud back towards me as I add water .
I am just hoping global warming and this dry spell continues.

Yes it’s also possible they go to a soak away. I rather hope not as the ground is clay, so much so there was a quarry and brickworks not that far away!
However without a lot of digging I am not going to find out where they go. What does slightly worry me is the voids in amongst the rubble under the existing patio path around the pipe. There are 2 options
- there was never any sand or small anything between all the rubble
- all the fine stuff has washed away.
Not sure the latter possibility is good news by the foundations!

I’d be pretty surprised if that goes to the sewer rather than a soakaway. As for clay soils here is a summary of a conversation I had with a council drainage department some years ago.
Me. I want to build 15 houses, I can’t find a storm sewer, will soakaways wirk, it’s a clay soil.
Council. Soakaways don’t work there.
Me. So how do the houses around drain?
Council. They are all on Soakaways
Me. Don’t you get flooding?
Council. Yes
Me. What do you want me to do then?
Council. Install Soakaways.
