Water valves are essential in the plumbing of every building and home. They allow for a quick way for the water supply to be turned off for a single appliance, one part of the structure or the entire structure. The problem with water valves is that if they are not used very much they can seize. Then when they are needed they will not turn. This is a problem that can be solved quickly, even for the inexperienced.

Instructions

  1. 1

    Apply more pressure to the valve using an adjustable wrench or pliers depending on the type of valve. Sometimes a wrench or pliers can give you the extra power you need to break the valve free. Be very careful not to apply to much pressure or the valve could break and cause a bigger problem.

  2. 2

    Use a lubricant such as PB Blaster or WD40 to lubricate the valve to make it easier to turn. Liberally spray the valve with the lubricant and let it soak for 20 minutes.

  3. 3

    Attempt to turn the valve again after the lubricant has soaked in, first by hand then by using a wrench or pliers.

  4. 4

    Spray the lubricant on the valve as you work the valve one way then the other. Most of the time the valve can be massaged into breaking free and working.
