That is obviously my first thought, follow by not tight a seal, a dirty surface where they seal, or physical damage. I think I have eliminated those possibilities yet it still leaks. I have been trying to figure out it will not hold water for several weeks. I am at a loss. It has never had a problem until recently. I am the only one who fills and it has not been abused. It is threaded properly.
