    Hi Guys

    Was just wondering if i can just go down the route of a double DI system as i dont have anywhere to really store water.
    This way i could have a tank in my van, connect a hose from my house and fill up, in a shorter time than an RO. As i would have to wedge my front door open for the hose.
    As i rent, i dont want to start building sheds for equipment/water etc.

    I have just looked up my water quality and its is 270
    Will a twin DI system bring that down and how much do you think it would cost per month.

    If not then i will have to mount a RO system in my van with a tank, what size RO would i need to fill a tank quickly?

    I really hope that the DI is possible, would save so much hassle.

    Cheers James

    It really depends on how much water your using?

    I use twin di and it works great for me as I'm in the same situation as you (rent, flat, ppm,etc)

    I use about 100liters a day on adverage and have to change resin every 6weeks. Hope that helps

    At this moment i have no idea how much i will be using, I am just starting to canvas work. Which at the moment i will do trad, but want to do wfp asap, that way i dont have to change over customers later.
    Also i am looking at the solar cleaning market, Got a supplier near me and hope to pick up work from him.

    I know that it would probably work out cheaper to have an RO working at home while im working and then just fill up. But then i have the storage problem,

    I am looking at tanks for my van around the 500/600 ltr size.

    Will twin 27's work with my water quality?

    My waters 276 & I use 4.5 litre twin DI's & am just about to change the resin in 1 of them which have been in there since last may & prob used 1500 litres. (Am trad so don't use much). I use 1 DI first add second when ppm goes up. When goes up again change resin in 1st one & use that as the second one & so on.

    It would work for a tank that size but you'll have to change the resin every couple of weeks if you use that much... You'd really need a di for that level of water
