You mean a backflow preventer? I may be wrong, but I've never heard of such a thing on a roof drain...

Backflow devices are commonly used in waste drainage systems to prevent sewage from backing up into the house or in potable water systems to prevent contamination.

It makes no to sense to me as to why someone would would install a 'backflow' pipe on roof drains. That would mean that you'd want to prevent water from flowing back up towards the roof.

If that were the situation, you'd probably have much bigger problems. Like a flood of biblical proportions, or you currently live in Australia.
