As above ?
Just interested really
Do you think a pump could be attached and used with wfp ?
How about transporting it ? safe or not ?
I would have thought not being rigid plastic and the absence of air e.g. as the water is used it would cause a vacuum would alter how the water moves compared to a conventional tank.
I have a van system and tank already, but I'm just curious

Yip,

Phillip Alexander from simpole has one in his van.

In America they call it a bladder tank. Seems to work fine.
