Hello
i had an idea
been looking on ebay, found some submersible pumps for around £30, and also some step up transformers from 12v to 240v
would it be possible to stick this in a water tank, and pump it into the back pack as and when you needed it,
or do these things pump fast not over long distances i.e through 50m of microbore
just a though, would seem a cheaper alternative to filling up the tank which would take some time, and also on pumps varisteam etc
