Going from round to square downpipe

[thesheep]

I've got square pipe sticking up from the ground, cemented in. And putting in new downpipe which I want to be round.

I've seen these square-to-round adapters which are always shown with the square bit at the top. I assume they can be used either way around, I wasn't sure if there might be a bit of a gap around the connection if I invert it?

Can I just one of these at just above ground level to go from round to square?

Looks like you will be digging the concrete up or bodging it.

Yep, bodging it is the idea. The underground drain there is a clay pipe and I don't really have the budget to ask the builders to dig it all up to replace that whole thing. So I'm trying to double-check that using the adapter I mentioned above is a feasible way to bodge it.

You could try and heat up the square section with a heat gun and push in the round pipe.

cut it closer to the ground and try a round socket https://www.google.com/search?client=opera&q=round+downpipe+socket&sourceid=opera&ie=UTF-8&oe=UTF-8

How about - Fit a square hopper at the top end of the your square pipe, with the round discharging into that?

But I don't think the narrow end of the round socket will fit over the square pipe (because on the diagonal the square pipe is wider than 68mm) or inside the square pipe (because on the smallest edge the square pipe is less than 68mm)?

That seems like it might work. I guess the hopper might look a bit odd down there (and my kids will probably dump leaves and soil into it!) but at least all the connections would be working like they should. So could be a workable solution.

So it seems like people think the round to square adapter thing I mentioned in my original post isn't likely to work? Is that because you can't invert them?

No you cannot invert them the upper part, has to mate by going inside socket of the lower part, other wise it would simply leak.

If cosmetics are not a problem, could you maybe put the end of round pipe in a bucket of boiling water to soften it enough, to enable you to reshape it to go inside the square?

OK. What's weird is that you can buy these square-into-round adapters everywhere, but it looks like round-into-square does not exist.

OK might try that, thanks.

It does not need to fit over the square , simply fit inside it. I would think it will go inside.

Ah right, got you. So the narrow end of the round socket is less than 68mm because it has to slot inside the standard round pipes. Worth a try!

Ah ha! Thank you so much!
