RESIN CONTAMINATION
Today Keith gave a demonstration in the workshop of what a serious case of resin contamination can look like. Our customer had reported low flow through their old water softener. Old resin (or poor quality) resin is sensitive to chlorine in the water supply, causing the resin to expand and restrict flow. When opening the inspection cap on the cylinder, the pressure that has built up forces the expanded resin to escape “out the sunroof”.
