After my first few days of going wfp and I'm only using tap water into my tank then through my 11 ltr di, I reckon I've only used about 5-600 litres of water and my tds has gone up to 004?
My tap reading is only 70ppm where I live and with that amount of water I thought it would still be 0
Is there a reason it's risen so quickly I was expecting a few thousand at least especially as my tap readings not sky high?

[elite mike]

I would not worry about it at that level.

[mufcglen]

Yeah I've not noticed any spotting ect on windows but I'd like to keep it on 0, don't want to let standards slip before I've even done wfp a week!
I've heard some people can run up to 020 before they notice spotting etc?

[dannymack]

I work up until 020, give your DI bottle a shake should bring Tds down.
Are you using a decent resin ? 👍🇬🇧🇬🇧🇬🇧

[bobplum]

second di vessel??

[mufcglen]

im using the tulsion mb115 resin which i thought was generally the best? and bob i got a second bottle ready to go in but just thought this first one would last longer than this?

The water flow going through your di vessel must be slow so the resin has time to work on the water. Water at a fast rate through the di vessel will make 'paths' in the resin and won't be purified properly. As has been said, give it a shake and slow the flow a bit.

Should take a few weeks or so before it starts rising to that level on the basis you are using about 300-400 ltrs a day over a 4 day week which is about what i do .

Although i purify at home into static tank with the right flow rate it takes about 8hrs to produce 300ltrs of pure .

Every few weeks i disconnect DI(s) give a good shake and roll back and forth a few times over table in garden . Mike

Could be tap water mixing with pure,

take riser tube out wash it then make sure o ring and filter are a good fit and stir resin while you got head off.

[PurefectWindowCleaning]

Yeah give the DI a shake.

Def should not be at 004 yet, no way.

[mikeyfaerosyth]

Think you can test the resin,

before stirring it take a spoonful out and put in glass,add a bit water then test it.

should still be at 0

[mufcglen]

Thought you was gonna say taste it when I read the bit about the spoon!!
I'll whip the bottle out in the morning and give it a dam good shaking then do anouther test!

[♠Winp®oClean♠]

As said, check your vessel, there is no way on earth your TDS should be rising at all by now. I work the same way & have same tap TDS & mine goes for weeks at 000 using more water than you.

[colin bird]

If your in a hard water area long term you will be better of with an ro.
What's your tap tds reading

[mufcglen]

Hi pal as above my tap gives 70-75 max ppm which I believe most people say 100 and you should be looking at ro so I reckon it shouldn't be eating resin this quick!

[mikeyfaerosyth]

If it dosent go back to 0 after a shake the tap water will be mixing with pure I reckon.

[mufcglen]

Cheers fella how does it get to mix with it, will it be at the top where the tube goes into cap?

[mufcglen]

Could it be done to not enough resin too?
When I filled the bottle up I just filled it up to the neck of the bottle then dumped the tube in!

[mikeyfaerosyth]

Not too sure must be inside the head,risers got to be a tight fit and there will be a small o ring you can feel with your finger,needs to be tight.

You can half fill with resin and it will still read 0,just wont last as long.

[♠Winp®oClean♠]

How many readings did you take & are you sure that what you put the water in didn't have any contamination?

I usually test mine 2 to 3 times to make sure.
