Depends on resin brand/quality, how hard the water is, how fast you pass water through the resin & wether you use 1 or 2 DI in sequence.

Trouble is, cleantech sell Purolite resin, one of, if not THE worste performing resin out there!!

I have been getting resin from Gardiners.  My TDS is 290 and the 25l splits 3 times into my 11l vessel.  I get about 575 - 600 litres of water before the TDS = 002

So 1725 - 1800 litres

Anyone surprised that I am now buying an RO?

No, not at all. 290 is way too high tds for a DI only system!  That's well bad performance though, even @ 290tds! Do you fill tank through your DI or from tap & pump through DI to pole?

[DanielUK]

Tank in van goes to pump then through DI and to pole.

Only using DI was always a temporary measure. Now I am going with bigger tank in van, static IBC at home with a submersible pump.  Upgraditus didn't take long!
