As far as the ALDA, you must use a 1-1/16" and a 24mm wrench. The ALDA has a stationary thread and the pump has a compression style fitting that remains on the pump.

Fit your wrenches in a way that you can turn either one in a manner to break the ALDA loose. One you break it loose, remove the 24mm and unscrew the ALDA. After you remove it, hold it in your hand and raise it above your head, stand above a trash can and release.
