...........you've guessed it isn't my own, of course! But a niggling problem with a hydration bladder in my rucksack.
Originally, many moons ago. I bought myself a Platypus. What a great bit of kit! It was easy to get replacement parts (a lost mouthpiece etc.) and not too difficult to keep clean with some Milton tablets.
During the time of the Platypus I also bought a water carrying rucksack made by Jack Wolfskin and it had its own bag. (To be honest, I liked the paw-print and the name of the bag 'Fata Morgana').
Last ski season, and plenty of seasons before, I used the 'Fata' bag for skiing until one day I discovered I was skiing with very wet undies - yes you've guessed (right again) the bottom of the bag where the tube exited from had cracked and was leaking mightily. So I binned it. Not the whole bag just the bladder.
In the meantime the Platypus was beginning to show signs of wear. The plastic around the tube attachment had become rather crinkly and eventually it leaked too. More wet pants!
For the Challenge last year I bought a Source 2 litre bottle. The kind that is a bag but will stand on its own if its filled. And at the same time a tube thing that will attach either to the soft bottle or any other bottle I want to use. Brilliant! This won't leak at the bottom cos the water tube comes out of the top instead.
I also bought a 1 litre soft bottle to use with my water treatment drops.
For most of last year's Challenge I used the 1 litre bottle which I discovered fitted conveniently into my Paramo jacket chest pocket. So I didn't really use the 2 litre except in camp and usually without the tube.
After that, during summer walking in the Alps and autumn in Scotland I used the 2 litre with the drinking tube in my rucksack. BUT there are a couple of problems with the set up.
First of all, it makes strange groaning and fizzling noises. Sometimes I even wondered if it was my imagination but when someone I was walking with commented on it I knew it wasn't.
Secondly, more worryingly, it seems to leak from time to time. I can only guess the water squeezes out of the breathing hole in the cap on top of the bag somehow. A couple of times there has been quite a lot of dampness in my rucksack.
Anyway, today I discovered another flaw in the system. Not only the strange noises, and the dampness but when you bend down to pick something up there is a veritable fountain from the drinking tube!
Can anyone suggest a system that won't leak?
