I couldn't find any hole.

Where shall I drill it? In the bend? On top?

Make sure the hole is facing down if not will spray up

I'm sure the first picture they will turn the hole to face down

Thank you very much for the pics, very useful!

I hope the pipes are not glued.. otherwise I will need a waterproof drill!
