Im setting up a deionized water system in my mobile detail trailer. The water in AZ is brutally hard. As I wash customers cars in the summer I want to be able to do a quick rinse down after washing to eliminate those pesky hard water marks. I use a Kranzle 1322ts that sprays at 2.1 gallons per minute. The question i have is do I route the deionized water system to run through my pressure washer hose or do I give it its own dedicated garden hose with spray nozzle running off a water pump? Does anyone feel strongly that one way is better than the other? I’ll be using the cr spotless which requires a flow rate of 2.5 gallons per minute. Does the hose and spray nozzle option sheet water better than the pressure washer sprayer? Would love your feedback!
