So will this work? attaching a small 700ml DI vessel to a backpack so i can use a submersible pump to pump water from my tank ( 34tds ) into the backpack and then purify on the backpack. So will this work? Will the pressure be affected?

Water at that tds, then yes probably, all though I would have concerns about the flow rate being too fast through the di. My question though, whats the point having the lightest pole you can lay your hands on to then add weight and awkwardness to the back pack. Just pump pure water into it to begin with.

My setup doesnt allow me to pump pure water into the backpack, to do that means spending an extra 400 quid for a purification system at home. At the moment I just purify in my van with 2 DI bottles from my 500ltr tank. I just want the backpack to supliment my vanmount, Luke
-
Does anybody else have something to say....please! Luke
-
Pump it through your hosereel into backpack,get a varistream and turn it up when using it to fill backpack.
-
I have a varistream but that wouldnt work because 2 men are using the system and with the submersible pump I can fill the backpack up in a few seconds, Luke
-
Take a T-Junction from after your DI. Connect a length of hose with a tap on the end. Fill the back pack with that. Thats what I do anyway.
-
I could do that but with 2 men using the pump even at full blast it will take ages to fill the backpack! All I want to know really is if my idea is possible or does it have flwas with pressure? Luke
-
No Luke listen very carefully,fill it through your hosereel after DI ie water going into backpack and not window,fill it during your tea breaks.
-
It will probably work ;) But there are many reasons why I personally wouldn't bother main one being weight!

I would do that if my suggestion doesnt work but I just want to find out if it will because it will be much quicker....oh and I dont have tea breaks unfortunately :( !!!!Luke
-
Weight isnt an issue, I'm big and if I'm not big enough I'll use a sack truck!!
-
Here is a diagram I did on paint, I even got got the shurflo logo!!!

so the hose that comes from the backpacks tank would go through the di vessel then to a on/off valve then to a pole! Luke
-
It should work, but as has been pointed out it will be heavier.
Perhaps you have invented a new product. When you have designed it and protected it, we will sell it for you!
-
I did think should i post it but I couldnt care less if somebody wanted to make money out of it. Obviously I cant divulge but my dad had an idea for a great wfp invention :-X :-X
-
Do you think that the resin would need chnaging often, and another thing, I have never held one of those vessels, are they a similar scale to my picture? Luke
-
They are about 12 inches high in total and about 4 inches across. It should be enough to purify 450 litres if using your water at 34 ppm.
Here's another thought Luke - why not try filling the backpack with a couple of litres of resin and then pouring the water on top. If you could find a way of straining the water before it went to the pump, you'd effectively have a very large resin canister.
-
so around 25 fills of the backpack! thats not bad. I know you once said you only sell products you believe in, so would I be right in saying that your not too keen on backpacks?
-
Hole in one.
-
luke if you want to reduce the weight even more you could opt for the 250ml di vessel from ro man.
obviously you will get less fills from it but should be a bit lighter.

Put some resin in a mesh bag and put it in the back pack. You could place it in the sieve at the top when filling and then put it in the bottom by the pump when using. Save carrying the extra canister around.

luke it does work, use a small inline vesell from ro man, you can refill it,

Luke I know the way you're thinking but a simple and quick solution is to have 1 or 2, 25ltr drums already filled with pure water filled from the di/tank tank in the van.
In the evening when filling the van i'm also filling 2 x 25 ltr tubs and backpack through the van DI system. Then if i need to fill the backpack on the following day i have 50 ltrs already and just quickly fill the backpack. I also have a freedom trolly so i'm prepared for anything a custy throws at me.

how about a sub pump from van tank to a DI cylinder and then to the backpack ?? ? ?
must be easier to do

Space is a in issue in my van now, I already have a 500ltr tank, 4 poles, 2 di tanks, 2 hosreels, 9 cones, trad gear, a frame, step ladder etc etc in my Expert!!!! So I need something that is cheap and small to supliment my vanmount! Luke
ps. I know I could use a little di vessel instead of a larger one but that would look messy because there would be nowhere to put it properly so I would like it all in one unit
