IT not Di or RO. ITs (1) Di,    or  (2) DI and RO and that depends on water TBS.

My water is around 180 tds before purifying....

so Ro is fine for me ,brings it straight down to 00 ... never used resin.

The cheapest way if you have good water as you do.... is a ro,very little to spend once its bought... pure freedom 300gpd around £150...


Its up to you but resin is expensive.

my mate spends £100 per month on resin.

fresh resin, not that offen, what i do is put the old resin in a di vessel as use thsi to fill up my tank with and this cuts down my tds of the water in the tank, can get away with using this resin till the tds gets high,  but i live in cornwall and have know my water to be 35 as well, its only gone high over winter

Are you on a water meter? That is an important consideration too.

im going to buy a system that i fit myself so saves me a few quid. so basically i need  an ro system? does having a ro system slow the flow down to the brushes?

a ro, and a system to wash windows are two seperate operations.

In the long run it would be cheaper to get an ro then. At 80 you are probably at the limit on going DI only. The Ro will get the TDS down to 0.

The other thing to consider is that DI is on demand. When you turn the pump on out comes pure water so you fill your van up from a tap and off you go.

With an RO you need some sort of storage solution as the water is made slowly over a period of time. Most go for an IBC tank and fill up with pure water once a day. This means you cannot fill up anywhere other than at home and you need to have the space for an IBC.

nope.... a ro system produces pure water with a pipe that you pop in the lid of the tank....and take it out when its full.... end of ro job...

the tank is then full and you need a pump to send your water out of the tank, into your reel, and up your pole...

the ro can be in the garage, in the van etc....its only used to make pure water, and you choose wether you put it into your van tank.... or a tank outside

you can pick up a 640 ibc in a cage for around 40 or 50 quid...hose to pump...from pump to reel.... then up the pole...

its easy to set it all up yourself.

i took out the ply on the floor and used anti - slip waterproof floor paint... then sealed any edges with a top shower sealant..

then i took two bungs out (rubber).... in the corners of the van.... so any leaks can escape the van.

if you dont have space at home,  why not get two di vessel  this will help the resin last longer, as you only have to swap one when it reaches 10 and all you do is replace the resin with the high tds and swap the places on the di

Daz is right, if you have probs

but you dont need any resin , if your water at 80 tds... a ro will do it every time
