Over a week later I recieved the correct 3/4 inch quick connects...
"These connectors were sent to me to correct a deficiency in my original order. I do not know if US Water has a QA department or not! My original order of Fluoride Filter and Whole House filters was delivered with different size ¾ and 1inch connectors making the interconnection of the filters impossible! It all worked out in the end but was a hassle (one week delay in system installation) for which I did not plan."
