Problem: The cap of my 5 gallon jug will not turn to open, is there a lock somewhere or is it glued shut?
Quick Answer: Just really tight! Grab a [pipe] wrench!
The cap of your 5 gallon jug has been sealed in accordance with the packaging manufacturers requirements for a leak proof seal. We ensure the torque is set correctly by using a torque wrench. For that reason, you may require a pipe wrench to open your 5 gallon jug for the first time. The cap's diameter is 3".
