G'day Weng,

No, the pump won't fit into a standard jerry can opening. 

G'day Luke,

Unfortunately not!  I have one of these showers, and am yet to find a jerry that will fit it.
We just keep a bucket on hand, it's easier to mix hot water, etc into it if you are after a warm shower.

G'day Rafael,

The Companion 12V Shower does not have an inline filter.  Recycled shower water which has soaps and dirt, etc that will block the shower pump and shower head over time.  If you have an option to catch and filter the water between showers that would work better for you than having a continuous cycle of dirty water.
Hope that helps.

G'day George,

The widest point of the 12V Shower Pump is 5.4cm so based purely on this the pump sounds like it is going to be much too large to fit your toilet setup.

G'day Jake,

The 12V Shower is designed for use with clean water, so if you're wanting to use it with river water then we'd suggest filtering the water before you use it. There isn't an easily attachable filter for this system, generally this style of filter is designed for us with gas shower systems like the Smarttek unit. We'd suggest sticking to using clean water with this shower head.

G'day Aaron,

The 12V Shower isn't really designed for use with drinking water, the hoses are specified as drinking water hoses, so it's not something we'd recommend.

G'day Beau,

The Primus 12V Shower has a flow rate of 4L/min, therefore the highest rate of water pumped per minute is 4 Litres.

G'day Rem,

This is a tough one to answer as it all depends on the size of the opening on your Jerry Can. To give you an idea so you can work out whether it will work for you, the pump at it's widest point in diameter is 5.4cm.
