Umm...mine broke! I'm in desperate need of a replacement soon! The set of threads that connect the main tank to the collection tank stripped and collapsed. Tried lube, etc...couldn't get it loose..finally gave up and got in the vice, but of course the vice warped it and not even the collection piece will screw back on now..total history. Not at all sure why it happened...I understand threading and am very careful with mine, but it stripped anyway. So now I'm back to dripping and there are lots of drivers swerving in the road!! Please tell me there will be more in stock soon!!
