I want to use one of these to blow out my water lines on a vacation
home. I'm going to try to connect it to an outside hose fitting.
Problem is this is a male and I need to convert it to a female. Are
there adapters I can buy to do that. Or is there a fitting I can buy
that is made to attach to an outside hose fitting on a residence..?

Thanks.
