The rat blocker works by using a single flap to allows the rats to leave your property but not go back up. Rats go for the easiest route to food and water. If they come to a pipe and it is blocked, it will stop them from going up the drain pipe. They will turn around and find an easier way to the next meal.
If you have followed all of the steps above, you should contact a rat or drainage expert as you may have damaged pipes which will need to rectified.
