My old wfp Escort van died a death some time ago. Before it went all my filters etc were stripped out (obviously) and put in to temporary storage. Finally got a new van (Citroen Berlingo) and am now setting up my wfp again. I am changing the way I set it up though. Previously I had everything installed in the van, now I am setting up the filters in my shed, filling a tank/water butt (not sure which yet), then filling 25l jerrycans which will then be used to fill my backpack which is coming this week. Following me so far? I'm confusing myself! What I need to find out is this:
1. Is it ok to run the water through the ro and di and then put it in to the storage tank, or best to run it through the ro in to the tank and then pump it through the di in to the jerrycans. I was hoping to avoid having to use a pump as we have very good mains pressure here and assume that option 2 would require some sort of pump.
2. How long does pure water stay pure when stored?
Any pointers will be appreciated, and I will endeavour to post some pictures of what hopefully will be a very neat set up.
Ps. I have got about 20 spare 25l jerrycans (or will have when I pick them up on Thursday). They will need a rinse out. If anyone is interested let me know. They'll be about £4-5 + delivery (will find out from PO what it will cost to send them this week)
Cheers
