anyone use a 12v pump for transferring water from the barrels to the backpack.
I find this the bit I hate doing and a pump might make it easier.
Hi Combat,
My son has a van mount and also uses a backpack. He carries a 25 litre plastic container and uses the van mount pump to fill the 25l container while he works with his backpack. We have Varistream contollers on each of our vans and he now has got the flow pretty much right. He fills his backpack from this container. he fills this container outside his van on the road with the hose that would normally be connected to his hose reel. The idea is that if he gets held up around the back for what ever reason, the 25l container can overflow onto the road and not into his van.
On average his backpack does 1 and a half houses, so it would be quite time consuming to wait for his packback to fill up with a 5LPM pump (4 minutes) or 2 minutes with a £100.00 10 litre pump.
Once you get a van sorted, you could also incorporate a seperate outside connection controlled with a ball valve mounted internally, and let gravity do the rest. I have been meaning to do this on his van, but as it will mean removing the tank to get to the outlet to "T" it off, I have procrastinated a bit with this one.

Having a seperate gravity drain means that you can drain the tank down if needed as well.
