How to extend AC condensate drain pipe

[perth9223]

Hi all,

I hope I am using the right terminology as I am not very familiar with air conditioners. I have this AC condensate drain pipe that was just left dripping directly next to the house which I understand is not ideal. What parts would I need to extend it to route it further away (to my veggie patch)? It seems to be 20mm.

Would something like this work? https://www.bunnings.com.au/holman-20mm-pvc-repair-coupling-fitting_p3140099

What do I attach it to though, should I get the same kind of rigid pipe, or something flexible?

Thanks in advance!
