How to change your DI resin

we hadEver wondered how to change your DI resin in one of the stand-up Pro 50 or Pro 100 systems. The tanks when filled with water and resin are heavy, so just tipping it over the floor would make an awful mess.

So we set out to find if there was an easier way to do this and we have found a great cheap, easy method to drain the resin as and when required.

TDS Reading

The only problem we had was that when we tested our resin before making this video the TDS reading was still showing 0000. meaning that the resin was still good. So after we made this video I simpled put the resin back in the Pro 100 and I think it’ll be good for at least another 6 months. When I had the CR Spotless system I would have to change the resin after 3-4 washes depending where I was in the US.

      Hi Peter
      Long time no speak. The prices on the resin can be found here: but it’ll cost you a fortune to ship to Sweeden. Also look at the new systems as they are amazing and the resin lasts for ages.
