I dunno what manufacturer it was, my old camper had a double action pump. A lever what actuated two diaphrams. Was great, easily pumped alot if its desired. A steady foot created a steady flow, over the ’squirt squirt’ of single action.
IMHO this foot pump is so so so much better than any thing on a sink where you have to touch the handle to get the water going
you save a ton of water cause you can regulate it easier I feel and when your hands are dirty you are not mucking up the handle on your sink then trying to clean that etc..
the clip and arm are photography you can get generic ones cheap enough works quite well I can clamp it to the table or the handle of the can like here or a tree branch for showers
I should make a fitting one day for the water can but the tube just has a brass fitting on the end for weight and works quite well to get every bit
also note the head also has a clip again I can unclip it easier to wash body but clip in for dishes etc..
if I make a fitting I want to make something that goes just inside the screw on cap that I can just quick release in and out of and the tube down inside will stay in place
bulb was a large one off amazon works well enough do want to try the whale pump I linked to above for camping
the way the paid white water ones work with the plate could be a good idea to keep it sinking down in but I have yet to have a problem with it and feel this is easy quick to clean to put away I store the hose setup wrapped up into a bag
I want to replace the hose with some quality silicone also that lays nicer and when it gets really cold this stuff gets stiff so I might say look into that as a what I learned
they can put out just over 2 gallons per minute that is a lot of water if you want
never used them with the notion of small amounts of water ? which I do now camping trying to save every bit on boats we were always around a fresh source to refill
I saw the river rafting ones and copied the idea of the bulb figuring they must have known or tried ? but maybe they never knew about the other ones so after using I was thinking hmmmmmm I know something that puts out more water but again never with the notion of saving or small amounts ? that is why I need want to try the whale for camping
they have a spring in them that helps the bulb part return shape but again even the regular bulb like I have so far has not let me down but it could be more water at times it is nice and simple ? so for how cheap they are but my plans are to put one into action and see if they were like I remember in my head
yeah no worries going to be a while before I buy one as my current bulb is working fine
after trying a few setups that double clamp thing is awesome and might be worth checking out purely for the man ways it can work price of a cheap hand held head and some tube and a bulb might be $40 ? and you are on your way
I have seen some folks make elaborate foot things with hinges and wood to help the bulb ? again for me its more simple the better worst case if you are around sand maybe a board to put the bulb on would be needed ?
