Title: Leaks
Review: This pump is great in theory, but the design is poor. The seal for the pump head leaks at any moderate flow rate, certainly under the specified 2L/min (or 1L/min for longer life setting). The water then drips directly into your water bottle. There is no way to just screw the head on tighter to make this seal tighter, so you are forced to pump at extremely low flow rates. Oiling the O-rings helps some, but it does not solve the issue, and it is not worth oiling them every single time I want to get clean water.This is not an issue of me abusing it as I have treated it with extreme care. It also isn't because I have been using it for too long. I have pumped less than 30 L through the thing and the water source was always clear, fast flowing water.I am sending it back and asking for a refund, I would recommend looking at a different pump.
