All you need is some epoxy, plastic tubing, and a clamp! Quote Link to comment Share on other sites More sharing options...
OlympicMtnBoy Posted February 27, 2014 Share Posted February 27, 2014 Sweet! Although at a 4 liter per day flow rate you may be sitting there for a while waiting. Good for after the apocalypse though, nice find! Quote Link to comment Share on other sites More sharing options...
AdamM Posted March 3, 2014 Share Posted March 3, 2014 Providing only 4 liters a day is quite slow, but you could potentially use something bigger instead of the small 1 cm price of branch they used, and use a bottle or something else plastic, like a pringles container.
