Hi, we have look into our current batch and it seems impossible to break it unless you over turn it. And the 2nd picture did show a force from the right around the circle crack. Did you recently reinstall the pump and overturn to break it? In this case, we can send you a a new elbow, or you can send the pump back and we can do it for you. Let us know.
this doesnt make sense.Both parts are snap off unless they are post to connect.When i first opened the box i took everything out then i opened the canister it already came off.To me that does not seem right.
