When it first came out it was superb. Lately though it never seems to hold zero for very long - anyone else having trouble?

I have a brand new bag ready but shouldn't need it yet.

Yeh the resins too hard up north. You need the softer stuff from darn sarf.

I have thought the same BUT......... when I think about it, I'm using much more water now than when it used to last for ages!!

Friend of mine who's just started up phoned me last night - his is creeping up already. He's only part time.

Might try Dowex next time, that was always good too.

Having the same, changed in May and already creeping up. I always buy from Das services and will continue maybe they can shed some light? I have a retro fitted DI on a pro6, Last year I changed at Easter 2012 and lasted over a year till May this year, I only changed it as it had been on a year still reading 001. Changing next week mines gone up to 003 already. Producing water now at 004 at start rising to 006 with a RO that is 4 years old.

I changed my resin in May, had to change it again this week as tds was rising. The last batch lasted much longer. I was thinking it was me using more water but seems to be a trend.

[Michael Peterson]

[britishwill]

[gary999]
