Evening All, Hopefully Littleocean will be able to help me out with this one. Stupidly with all the cold weather last week, I didnt venture out to the shed to disconnect and drain some of the water off my RO System. DOH!! As a result, the water inside has frozen and from what I can tell has destroyed one of my chambers on the 4stage RO-MAN system. Ideally if not to expensive, I'd like to replace the one broken section and be back up and running. But dependant on cost, I may replace the unit as the filters need changing as well. To provide all the information this is the RO-MAN Professional 50 Gallon system from 2009.
