It is contaminated.

contaminated with wat

[Tim Rose]

Some kind of total dissolable solid I guess. (TDS).  Try to find the source of the pollution.  Don't use copper fitings.

[m.b.s.]

i dont use copper fittings just plastic

How much water did you make until it went to 001.
What is the reading of the water after your R/O but before the D/I.

500ml cannister is not going to last long anyway.
And at 001 i would not worry i let mine got to 003 before i change

009 is the max.

[Tim Rose]

What is it after the DI?

[m.b.s.]

was 000but now001

My readings are not far away from yours, I put in new resin and after 1 day it goes from 000 to 001 it then stays there for about 1 month so dont worry

[john tomkins]

009 is the max.

I dont think you'll catch many on here using water at 009
Once mine gets to 003 it gets changed, even then my IBC reading will only be 002

With ne DI resin if its not packed into the chamber properly it can form channels, where rivulets of water can run through a little too fast thus it doesn't get polished quite well enough. Open the DI chamber, pack it in tight and maybe top it up too. Try testing again after 10 mins running time.

its gone back to 000 0n its own have done nothink too it just checked it before filling tank and it is showing 000  weird or what

[D.Salkeld_Ltd]

M.b.s,

Don't worry about 1 point out.  Are you testing a sample straight out of the pure out let?
Test the tank.....it will be 000.

My system (100gpd RO man) does the same.  004 out of RO into 750ml DI new resin 000 after about 200 - 300 ltr pure 001 but tank is 000 for 2 weeks (about 1500ltr pure)

Shake the resin vessel to get the most from it.

009 is the max I would use, some are weak willed and crack when the tds is around 003.

Stay cool and push the limits. Why pay more?

If you use it at 009 why not try 010 its only 001 more, why stop there
If you're prepared to risk it for the sake of a couple of pounds  :

What I find a lot is the rubber ring on the top that seals the cartridge can sometimes not be seated properly allowing a small amount of water to pass through.  Another thing to do when necessary is flip the rubber over to the unused side.  When used a lot of times the rubber can have a lot of circular indents that can also allow the water to pass through without going through the resin.

1ppm is nothing at all, you can use it much higher than that.  I wouldn't look at it as saving money, sometimes it's not convenient to change it as soon as you notice a reading.
