I would prefer to buy a portable shower with the electric pump already assembled & assembling it yourself is not a good idea you only showed us how to assemble the shower you didn’t show us how the shower worked
Unsafe and bad company. I do not want to put an improperly sealed electrical device into water. The instructions stated that there were 2 O-rings pre-installed. They were not. There were two O-rings and two black rubber rings in a package with no instruction. I emailed the company twice with no answer so I returned.
