A simple message really. Dump tank drains are generally designed to be stowed in a particular manner. It is best that you are familiar with how they are designed to be stowed. There are number of different methods of drain sleeve stowage attachments.....they can vary some between manufacturers....and even within the same brand over time. Be familiar with yours. Take a video of it for your members so they know how to do it. if you are stowing someone else's drain sleeve....well, ask them if you are unsure.
