I just purchased a BP20 bladder press + am having trouble attaching the input water hose. The manual shows a quick connect on the input side of the pressure valve, which I have not been unable to remove. I'm rotating this plastic piece in the direction indicated - but the thing doesn't seem to be removable. Does anyone know what modification is needed to attach a standard garden hose to the input valve? I crushed whites today + should have already pressed them. Sure hope someone on this forum has an answer to my problem.
