The white vessel on it's own is the Di vessel filled with new resin and only used about 3 times....the blue thing next to it is a spare resin holder for the Di with old resin still in....the brown powder in the bag is new resin for the spare.....the resin in the Di lasted me 10 months before TDS crept up to 001ppm but my tap TDS is 095ppm.....the water enters the DI from the Ro at 002ppm.
The 3 bottom vessels on the Ro...the one on the left is the sediment filter which looks a little murky but works ok but to replace it is a 2 minute job and they only cost around £2.
I also have the spanners for changing the filters but not shown.
