I need to turn off the gas to to the house to do a repair of an appliance without its own valve. It seems stuck as I cannot turn it with a crescent wrench.


For future reference: get a piece of pipe large enough to slip over the handle of the wrench, as long as will fit in your space, to increase the leverage. We call them "persuaders".


After another attempt, I succeeded. I reoriented the crescent wrench in the opposite direction (concave side away from me) and pulled towards me. I believe this gave me more leverage is it was significantly easier to turn.

Other ideas that I ended up not trying but may help as well:

  1. Getting an extra large crescent wrench (expensive).
  2. Getting a tool with linear slot that fits over the valve's knob which appears to be created for opening valves.
  3. (Rob's suggestion) As the valve is located outdoors, there was a bit of rust or dirt that can add friction to the valve. Using PB Blaster or Liquid Wrench can help loosen things up. (NB: please check if this is safe)

    you don't mention the state of the valve but if it's outside and been sitting a long time, it might be rusty. Next time a penetrating oil like PB Blaster or Liquid Wrench might help. – Rob Elliott Nov 12 '18 at 18:42
  • @RobElliott It is outdoors and looks slightly rusted. That may have helped indeed. – imagineerThat Nov 12 '18 at 18:50
