So I changed my resin over end of December after ordering some Tulsion from PF in September.

I use an 11L DI vessel and have a TDS in of 019. 

Right after changing the resin in Dec TDS was always at 001 and has now risen to 003 after making around 4000L max.

Any ideas what's wrong here? Could it be a bad batch of resin given that it was always at 001?

I can't see any obvious problems with the DI vessel itself.

Cheers, Mike

Have you caliberated your TDS meter?

I've just bought some of this stuff....thought it seemed to be the best stuff out there?

was it sealed ok when received it?

make sure you have emptied and cleaned out the vessell properly.

make sure after adding the resin you top it up a little with pure water, makes it easier to get the riser in the vessell 100% correct and that could be the reason why you have problems.

to be honest i was finding the resin from pf didnt last as long as the same resin from daqua, so i always use daqua now.

must be something wrong firefly, 1 bag lasts me just over a year, and i have a tds of 46 and i am di only, are you using the right tulsion, remember their are different grades 115 or slightly lesser grade 111

Just over a year? I bought tulsion 115 in October and im needing to get a new bag soon. How many days a week do you work and how much water do you use a day?

[AS Window Cleaning]

and what tds do you both change at? if one of u changes at 15 and the other is part of the  quick. it's. reached 001 tds brigade, could be a difference in usage levels.

[Jonny D]

I work until it reaches about 10 as i heard that after 10 it starts to spot the windows.

S'cuse me askin' - but what's the tds going in to the resin at? Is it higher than it used to be?

[Mike55]

Colley614 - yes TDS meter is fine.

WC Solutions - I will try that today.  A good clean out of the vessel with pure, add resin and top up with pure.

AS Window Cleaning - yes this is good stuff and I've always had plenty of life from this resin in the past.  I have always purchased from daqua though.

Gold - TDS in has always been around 020 in to resin.

I raised this point a few month back. Tulsion does not seem to last as long as it used to. No way to prove it tho!
