Step One: Identify The Draining Ports
Typically a door will have three drainage ports located at the bottom of the frame, one in the middle and another in each corner. The drainage holes are generally small slots that direct flow outside of the frame.
Step Two: Testing For Blockages
To check for blockages a small, thin object such as a screwdriver should be used and inserted to each port. If resistance is felt then it is likely the ports may need to be cleaned. They can also be tested by pouring a small amount of water into them and seeing if there is a steady flow from the other side.
Step Three: Clearing blockages
If the ports are blocked or contain some dirt that could accumulate to a blockage they should be cleaned. This can be done simply by using a hoover with a thin nozzle attachment and hoovering the dirt out.
There could be a number of possible reasons why your door is leaking. The seals around the edge of the door may be failing and need replacing. They also could have come out of place and need to be pushed back into the correct position.
Your door will have three drainage holes at the very bottom that will drain out any rain water that might fall into the frame when the door is opened and closed. It's best to clean these regularly and make sure that they are not blocked with any debris that could be causing the leak. Follow our handy step by step video below to find out how you can clean the drainage holes at the bottom of your door.

Your door will have several drainage points in the frame, these can occasionally get blocked with debris. You can unblock them using a thin screwdriver. An occasional light vacuum of the threshold should remove the build up. You can test the drainage by pouring a small amount of water through the hole. Avoid standing on the threshold as this will cause accidently damage which isn't covered by warranty.
