Hi Dean

Don't know what they cost nowadays but i have 2 x 11Ltr DI's onboard my 400ltr van mount & they work perfectly. Tap tds of (approx) 90ppm & use DOWEX resin.

he uses two in line so when the second  ones tds starts rise he puts it at the front replacing it with his other di with new resin the second one then takes the crap out of the water which otherwise would have been thrown away when it went above 1 or so ,therefore saving money and resin
