I'm trying to locate the water shut off valve for my home. I'm trying to shut-off the water to replace and outdoor faucet. I've attached 3 pics of possible locations for it. Can anyone identify it for me? In case it matters I live in Hawaii. Notes: In pic #1 I already attempted tightening and loosening the pressure regulator bolt. It doesn't stop the water.
In pic #2, I attempted turning the large bolt head on the bottom right (next to blue meter cap) of the pic with an 8-inch wrench. It wouldn't turn. I was hesitant to buy a bigger wrench and put more leverage into it until I got some advice...
Pic #3 is just a photo of my front left outdoor faucet. I only included it because the home inspection report I dug up listed the water shut off valve as being in the front left of the house. However, this is the ONLY thing that is not photographed by the inspector in the report, so I suspect it was made up and he never actually found it. But maybe the black sewer cap in the bottom of the pick is something to do with it?
