It's "half cocked." It's a firearms reference. You can't shoot an old-fashioned pistol without cocking it. If you only halfway cock it, it won't fire properly, so "going off half cocked" means you jumped the gun and leaped before you looked.
The term half-cock is as old as flintlock guns and appears in print from about the mid 18th century; "The gun being at Half-Cock, the Spring acts upon the Tumbler with more Advantage." The earliest known use of the phrase 'going off at half-cock' comes from London and Its described, in 1761 as "Some arms taken at Bath in the year 1715, distinguished from all others in the Tower, by having what is called dog locks; that is, a kind of lock with a catch to prevent their going off at half-cock." We now commonly use 'go off at half-cock' or, in America, 'go off half-cocked', to mean 'speak or act impulsively and without the right preparation'. And therefore this clearly alludes to the sudden discharge of a firearm. Despite that, the first use of the phrase had a completely different meaning. When the 'half-cocked' was used it was supposedly to mean tipsy, or half-drunk.
To "go off half-cocked" is a reference to older firearms that required a hammer to be cocked in order to spark the powder that fired the projectile. These cocking mechanisms typically had two settings, a half-cock and a full-cocked position. The half-cock position was for loading and would not allow the gun to fire by pulling the trigger. When loading was completed, the hammer was pulled back to the full-cock position and the trigger-safety was disengaged. Going off "half-cocked" is a reference to a firearm discharging prior to it being ready. If you "go off half-cocked" it means that you attempt something without proper preparation or aforethought.

The main stop cock is usually near were the water pipes enter the house from outside - mine is in my kitchen. There may be a stop cock on the header tank in the loft, or on the inlet pipe to the hot water tank, or in some other places, such as below the bathroom sink, and so on.
