Resin help please
« on: October 01, 2017, 01:32:15 pm »
I have a purefreedom 500l van mounted ro system.
My tds  normally starts to rise approx every three months,I then change both pre filters and resin,this has been the same for the last ten years.
Today I have changed my two pre filters,when opening the resin bottle,I found some of the resin to be a greeny/ black and looks like the resin has gone mildew.this has never happened before.
I've always used tulison resin,and also flush ro every few months.
Any help or suggestions appreciated.
Many thanks for reading

Never had that. Where did you get it? How long has it been in? How many litres has it produced? What's the tds at? Has it been left unused for any length of time say, while you've been on holiday?
