Don't panic about water not being at the magical '000' :

There's no law saying it should be - it's just a convenient figure to use as a benchmark for water pure enough not to leave spots.

We operater up to 010 without any problems and have on occasion gone a lot higher.

'000' water is not 'pure' - it just has less than one part per million dissolved solids in it.  The electronics industry uses water down to one part per billion or less

Erith, wash out an old glass or jam jar and rinse it out with pure, then fill that and take a reading, you will be surprised, I bet it'll read 000.
I use to just use the cap on the TDS meter and it use to say 005 then used a glass and got 000.

thanks for the replys i think its me i just need to get used to it a few weeks and i will be fine im going to buy a spare 10" di filter just incase

got another question about the water after ro its about 025-030 after the di its about 002 does this mean the di needs replacing the di has only done about 300ltrs

Not necessarily, watch it and think about changing it when it gets to 5-7 Its the fact that it changes that indicates the resin is knackered.

 It could just be because its new. Its also possible that resin doesn't take out all every sort of impurity. It takes out limescale but there are about a million other possible things disolved in your water . Your system might always run at this sort of level
