    Hi All,

    My water coming out the tap is at 100 on the TDS I've got a 25L DI and using it to fill up my Trolly system at the minute!!

    Am about to buy a Van system but am not sure if I should get a RO??

    Is it going to cost me lots more money without one??
    Obversely it depends on how much water I use!! I don't like the sound of using an RO and throwing lots of water down the drain every night. I have seen I video on you tube of people using two DI vessels?

    100 ppm is very good, mine is 250 ppm in my area hence we use a RO. Although 100ppm is good it is still quite high and your resin will degrade very quickly, You will spend roughly 60 to 80 pound a month on resin although that is depending how much water a day you are using. You will be better running two DI vessels if you go that route as you can switch between the two, so when one vessels degrades that one vessel becomes your first vessel so you can always cut down on ppm going into the second vessel. Then when second vessel degrades you use that one as your first vessel. This will help you cut down on half your resin costs, only ever change the resin in one vessel at a time!

    But from personal experience i would NEVER use just DI vessels, The ppm will jump up VERY quickly if you dont check it daily!
    I would never trust using just DI resin on customers windows alone.

    My system runs at 240 litres an hour an i supply for 4 people, i use only 12-13 litres of resin every 7-8 weeks using my trick mentioned above and thats for 4 people! An RO is very cost effective and will save you a fortune long term!

    Need to know your water usage really.

    But RO all the way for me, as if for some reason DI's went wrong or broke, at least you can make usable water with RO. You can always use some of the waste water as well :)

    starting out am not going to be using much water to be honest but am sure it will build up.

    so sounds like an RO is going to be the best option even if it will cost me more money to start with.

    ive got room for a RO unit and a large tank in my garage so might go down that route.....

    If you dont get an RO you will regret it trust me! Dont go for a cheap low flow rate either the better and faster one you can afford the better it will be for you in the long run. End of the day it all depends how you want to run your business, how much water you will be using etc or wether you end up supplying water for anyone else.

    Thanks for that Damo.....

    When I start getting more work it's going to cost me a lot of money in resin....

    Looks like a will get an RO system!! Maybe one that is built into the van, I will plug into the main water every night and let it fill up!! My Pressure at home isn't amazing......Hopefully I don't need a RO pump too

    My water is 270ppm and I use just twin di. I have to change the resin every 6weeks. I use around 100-200ltrs a day. I have storage problems (live in a flat) and I'm on a water metre so for di works great for me.

    If I was in your situation though I'd get an ro because you have the space even though the initial outlay if a lot more.
