I have a backflow preventer attached to my outside hose bib. When the water is running, it leaks slowly so I'd like to take it off.
I used an adjustable wrench and the bottom part of the backflow preventer unscrewed. This is the end the hose threads onto and the end with the washer.
How do I remove the other end of the backflow preventer - the end actually threaded onto the hose bib which enters the house?
There appears to be a tiny hole inside - would there be a small screw holding it on?
Thanks for the assistance!
