Have I Damaged The Di Resin?

[norite]

Got my first RO unit installed Our local fish shop closed down, so there went my local RO supply...down the drain...

The instructions said I must run off 5 US gallons before using the water or plumbing in the DeIonising (DI) unit. Sadly I got so inolved in getting it setup I forgot what the instructions said and plumbed the DI unit in. It had done around 6 litres (2 US gallons) before I read the instructions again, realised what I had done, and quickly disconnected the DI unit.

Will the DI resin be useless now? Can I still use it, or should I throw it away and replace it with fresh resin?

I dont think it will but just a guess im afraid.

Potentially yes, is my guess. RO membranes are shipped in a resin to keep them damp in transit, that has to be "flushed" off the membranes before you use any of the produced RO. I don't know what resin, or whats in it more to the point, any brand uses, but in the likely event it has an ionic charge, it will have spent the DI resin in the post filter. I'd replace it before using unless another member can confirm either way

On a side note, it isn't the type of resin that changes colour as it spends that was supplied with the unit was it? If so, has it changed colour? If so, it's spent and needs replacing. If it hasn't, it's fine

Or if you like to play with chemicals you can Recharge your own DI resin

Thanks for the info everyone!

I changed the DI resin anyway; it's cheap enough to buy more...
