The water at my newest location is 25 grains hard. I have been softening all the chemical water on the IBA and all the SS low and HP functions. I've noticed some of my valves sticking on my new Razor and a white film on my machine, fittings, bay panels, signs, and pay-station. I went ahead and re-plumbed the IBA yesterday so the entire machine is on soft water. I've read on here where hard water rinses better but should the quality of the wash be the same using all soft water?
