I have this coffee maker and am disappointed in it as well. I've tried a variety of coffee's and they seem to come out burnt tasting. My carafe does not leak like everyone else says but it does get water down inside between the interior insulating wall and the exterior wall somehow that is impossible to get out so it will constantly sound like water is swishing around (because it is). Would NOT buy again.
So, testing with actual coffee at the same temp as water results in a massive leak. I can only conclude that something is changing the properties of the liquid and allowing it to get past two quad rings. Very strange. Ok, so unless I can find something with a larger cross sectional area, I'm out of luck for now, dammit.
Ok, subsequent testing has revealed that size 150 X-Rings(Buna 70 durometer) have thus far yielded the best result yet. I tested it with water at machine brewing temp and detected no drips while pouring. Note that that this test was conducted only once and used two X rings, one in the original location and another near the top of the lid. The small sample size may preclude any statical conclusions.
I've done more than a few pots since my anti leak mod and I wish I could say I solved it, but I think I need a bigger X-Ring. Maybe one step up to 150? One pour it seems ok. The next it's Victoria Falls. Odd that.
On another note: I am not an engineer, but i did work as an engineering technician and quality control test technician for 25 years before medical issues forced me to retire. So I'm not an expert on anything, but I know quite a bit about many things.
