The ones that can never be turned off as shown in many films on TV, the hero is shown struggling drenched to skin some times with some lever and the valve will still not turn,
well i checked my mains valve and it took an hour with plenty of coaxing to get it to turn free, have you checked yours?

That used to be the adventure every time I started a new plumbing project in my old house. Most of the shut-off valves were too old and corroded to shut off completely, so the first part of every project was turning off the main water supply to the house and replacing the shut-off valves (or just installing them where they never before existed and should have...who installs a bathtub with no shut-off valves?).
 
If a valve has not been cycled for years, there is a really good chance that it will not open or close easily. I have pressure tanks on the pumps for both the dug well and the drilled well, and I seat and open the isolation valves for those systems twice a year, My hairy moment this spring came when I activated the pump from the dug well and valved it into the sill-cocks for outside uses. Apparently, one of the self-draining sill-cocks had frozen some years back, and the previous owner decided that instead of replacing the bulged and split valve-body, he would make a bubble-gum repair by gobbing solder on the split. The air-and-water hammer that the piping experienced when I charged the sill-cocks was sufficient to blow out the solder patch and as luck would have it, the split was perfectly positioned to shower my breaker-panel with sheets of water. I put on a thick plastic glove, opened the breaker panel with a metal poker, and pushed off the well-pump's breaker with a wooden stick, then slammed the breaker-panel door shut with the stick. Lucky me - didn't get fried.
 
Just managed to collect enough brain-cells to have worked out a more reasonable fix. Open all the sill-cocks wide open so that the ruptured one wasn't spraying sheets of water on the breaker panel. Open panel, shut off breaker. Duh! Sometimes I'm such a dope!

:smile: A sheet of plastic on the breaker side of the sill-cock might have deflected the spray in a safer direction too. :biggrin:

Oh, sure! Display my hick-dummy ignorance to the world!
