I took both the flap valves off my drain pipes, cannot see any reason for them being there.
Whilst there may not be a need for those pesky flap one-way valves on the drainage pipes in this country I could see in some countries of the world where it would be an advantage - just imagine poisonous spiders or snakes running around the innards of your car or other such creepy vermin.
