Storm sewer connections

[Ingseven]

Hi,
does somebody know a link with details of storm sewer connections between existing pipes and new pipes when they don't match exactly in length? Some kind of sleeve or similar.
Thanks

For short distances you can use Neoprene "sleeves". In our part of the world these are called "Calder Couplings".
