Once I worked as a sanitary technician and learned a way to use the sewerage for free. But I and other employees were fired because we used this method.

and. Now I want to avenge them, and I tell you this way. We did this: you squeeze your hand in a push on the elbow, then sharply you pull, and the crap for 2 hours bats for free!

and. It works 100% on all toilets.
