Fozen RODI Shattered

since it was frozen I would replace, but in the future you can test rejection. Say your TDS in is 100 and your tds after the ro membrane (NOT AFTER DI) is 2, your rejection rate is 98%. Every membrane has a rejection rating and when they are worse than rated they need to be replaced or you will chew through DI.

Thanks for your help. Makes perfect sense to me.
