My big problem with the Waterpik

My big problem with the Waterpik is its intermittent leaking. I make sure that the tank and the pick attachment are properly seated yet the machine will periodically and inexplicably start to leak. I will go in the bathroom at various times during the day and find that everything is OK with it. Then I will make another trip and find the Waterpik sitting in a puddle of water. To be able to use it without having this problem I have to empty the storage container after every use. That's something you are not supposed to have to do. In reading other reviews of the Waterpik on the internet I've found that I am not alone in having this problem.
