Hi,
I am not sure whether that is back flow attachment to end of it that is causing leak when hose is attached and water is turned on. Currently water is spraying all over. I saw some youtube video's and they suggested that there is small set screw on back flow device and I looked all around but could not find any hole with any set screw. I even don't see any hole.
I tried unscrew using wrench with some pressure but it did not budge so I just want to make sure that I don't break anything while unscrewing.
