Will Having 2 DI vessels be a lot cheaper than having one with water reading 270 on the tds? Will I have to change resin frequently by doing this?

Same here, first lot of water from a new bag read 001ppm. It's up to 004ppm a month and 4000L or so later. I use twin di and the first vessel was throwing it out at something like 016ppm into the second with new resin. Strange.I use twin di as does M my ppm is 240 too .But this last lot of resin doesn't seem to have lasted as long as tbe other times I have refilled maybe ive had a dodgy batch ???
No, sorry, I posted it wrongly. The first vessel is now about 016ppm (probably higher as I checked that vessel a week or so ago). The second vessel is reading 004ppm.So from 4000 ltrs it's gone up to 16 or whatever it is? Should it last longer than that?
