[easy clean]

my set up used to consist of 1 x 11litre di vessel after ro. resin from ro-man lasted absolutely ages, prob about 6 months and i must use at least 3500 litres a week.

then resin needed changing so decided to buy a second vessel (11 litre) and put them in line, am now using rohm and haas resin and already my reading is 01, lucky if its lasted 6 weeks.

not doing anything different at all.

any suggestions? my only conclusion is rohm and haas must be real 5h1t

Rohm & Haas is one of the best resin on the market, there could be severals things that might be causing this problem.

1  The resin is packed into the di tank to tightly

2  The water flow might be going though to fast

3  The resin was left in a open bag which does affect its lifespan
