With much respect to Old Coot and YouRoo (both of which are very handy and helpful
) flipping faucet over does not fix this problem. The repair is some what simple. Turn off any water source and relieve pressure. Cover or plug drain to prevent losing small parts. Turn knob to the right all the way, do not move it from this position from here on out. Remove faucet knob (remove cap and Phillips head screw). It should look like this.
I have hi-lighted the valve in the off position. See how it is "D" shaped?
Now it gets a little tricky, pull this valve assembly out of fixture by removing retainer nut and pulling on valve (careful there is a spring loaded rubber seal behind valve it does not fly out unless there is some water pressure but it could fall out). The metal plate on back needs to seal hole where rubber seal is(this will be the off position). The rubber hole is on the right inside opening. The solid portion of metal plate should be on the left when looking at back of valve.
The metal plate pops off easily with finger nail or small screw driver to re-orientate. So to recap, front of valve is in "D" position and metal is as shown in picture when looking at back of valve. Reassemble valve the valve fits two ways in notches 180 degrees from each other make sure your valve matches first picture.
Sorry all pictures came out sideways. Smart phones are not as smart as you need them to be sometimes.
Disclaimer If you valve does not look like this these instructions may or may not help.
I had to make a couple of attempts to get it right myself. So if it did not work retrace your steps.
BTW this is cold water valve if hot is you issue it will be the same.
