bought one of these kampa units last week,
tested it today - without gas. seems to work well, good water flow and shower spray
at first i was annoyed as instructions said attach pump to a water container, but the pump doesnt fit any of my containers. then i read the pump is submersible.
worked well, but the shower head leaked... no o-ring. so i tried with a o-ring that improve things, then lots of PTFE tape to seal it, that stopped the leak there. but it also leaks a bit at the on-off switch on the shower head. may just fit a better shower head
fitted gas hose to the unit and regulator this evening, so will test it tomorrow for hot water
3 litres lasted about 1min20secs
going to need a to carry a lot of water for the Mrs showers....
now got to figure out where it will fit in the boot during a trip, as it is quite bulky
