I am renting a new place and there is a spicket in the back and a garden hose near it but for the life of me I can’t find an adapter or hose that connects to it. I went to Lowe’s and they said it needs a vacuum breaker and recommended I get the one shown but that also doesn’t work. Am I dealing with a weird cheap bibb or is it European or what.Measurements are the OD and ID on it.
