Miscalculation with the down pipe

[overlander matt]

I need to return to a down pipe and drainage job that I 'finished' a few years ago. Unfortunately, the new cast iron down pipe finishes just a bit short of the new plastic underground drainage. I'm not sure what the best options are - I don't really want to shell out for another length of 4" cast iron.



The cheapest/simplest option would be to use a slip coupler but this is likely to leave a bit of the couple exposed. I could paint it and perhaps add a brickwork surround to cover the pipe. It won't look quite right though... I also need to hide the plastic pipe trap that is slightly above ground at the moment which I think might involve creating a bed with a load of gravel to bring up the ground level.



I do have one 1.8m length of 4" cast iron for the soil pipe on the right of the photo so could cut off the eared socket to finish this properly. It does seem a bit of a waste and I'll still need to extend the soil pipe (albeit only for vent purposes) with something!

Has anyone got a good idea to solve this one? Thanks in advance.

But the plastic soil pipe was always going to be visible anyway, even if you had used a longer down-pipe?
Were you planning on leaving that visible?
I'd just extend the plastic pipe with a suitable joiner, sawing a bit off the end if necessary to get the joiner in. Then paint it all black.

You can get adapters to connect cast downpipes to plastic pipes. A bit ugly maybe when done above ground but the spacing looks good and it would make it accessible for maintenance. Black paint is brilliant - nobody will see anything.

I have a similar connection of cast iron to plastic above ground and have used one of the rubber couplers. The plan is to build a small brick surround for it to hide it

Many thanks for your suggestions. I vaguely recall the cast iron will push into a plastic coupler. Perhaps a coat of black paint and a bit of brickwork will be needed. Either way I must get the pipes connected before the rains start up!

Facebook Marketplace seems to have a fair bit of cast iron guttering both old and new available right now. Not terribly local but perhaps another option.
