Was going to buy a di system but tested water out of tap and was nearly 200 do I have to get other system ro is it
Will it cost a lot more and do I still need resin

[DeLuce]

Imo, with a tdi of 200 I would get an RO kit. The system you need would depend upon your round size, if you always use wfp on the glass, or are you part trad part wfp.
I am all wfp and use a 450 GPD unit, does me fine. This seeps into a 1000ltr tank.
On the other hand, you could get the RO system in your van. I use DI resin to polish off the RO water before going into the tank. Usually 5 on the tds before resin then 000 after.

There are other places too, others will give you more info.

I have recently bought an RO system after using DI only for the last few years. Its brings my tap tds from 175 to 11 and so I still need to buy resin to bring it down to 0tds, however it is working out considerably cheaper than DI alone. The best decision I have made since going to wfp.

Could do with some more info to help out a bit more John.
Do you have a van or running job from a car with trolley system? If ban, what size tank? Do you have a holding/collecting tank? Etc.

Get a 450gpd R.O - http://www.daqua.co.uk/ro_systems.htm (bottom of page)

You may need a booster pump (check your water psi with a pressure gauge, anything less than 40psi get - http://www.purefreedom.co.uk/purefreedom-aquatec-pump-p-651.html)
An R.O needs high pressure to work efficiently, so a booster will bring your tds down and you'll produce water faster

A 450gpd will produce 1000litres of pure in around 24hours (i think) so you'd be better off getting a 1000litre ibc (if you have the space) and produce your pure water into that (therefore storing it for as and when you need it) Buy a submersible pump, so you can then transfer your pure water from your ibc to your van tank/barrels

An R.O will not bring your tds down to 000tds on its own, so will need to get a D.I with resin as well. It just means your resin will last ALOT longer
