Tech - Water Warriors Orca Internals .:
Images from iSoaker.com
Note: most of these internal pictures are missing the proper configuration of the trigger/valve-nozzle lever as it was removed for repairs. The last picture in this set shows the repaired nozzle valve assembly which is what a stock valve would look like (apart from the additional glue/wire).
