When I installed a new dishwasher I had to set the water hardness for proper operation. Can you tell me what the average hardness is?
Kiawah Island Utility and Johns Island Water Company do not treat the water received from Charleston, therefore the Charleston Water System results are reflective of the water delivered to the residents of Kiawah Island. According to Charleston Water System the average hardness is 56 parts per million (ppm). You may go to their website at www.charlestonwater.com for up to date analytical results.
