Ways On How You Loosen A Stuck Shutoff Valve

There’s nothing worse than getting ready to start a plumbing project only to realize that you can’t turn off the water supply. Plumbing valves have a way of freezing up over time, and that can make it difficult to do even the simplest repairs. So below we will explore the best ways to unfreeze or loosen a stuck shutoff valves.

How to Loosen a Sink Shutoff Valve

Sinks have shutoff valves attached to their pipes that allow you to turn off the water in one location instead of the entire house when you need to work on the sink plumbing. Sink shutoff valves can freeze or stiffen due to mineral buildup or disuse. The packing nut of the valve, also called the bonnet nut, is unscrewed to loosen the shutoff valve knob and make it easier to turn.


Turn off the water supply at the house meter.


Grasp the bonnet nut, located directly under or next to the knob of the shutoff valve, with an adjustable wrench. Grasp the knob of the shutoff valve with another adjustable wrench.


Hold the knob of the shutoff valve in place with one wrench while you turn the bonnet nut counterclockwise with the other adjustable wrench. Try to move the valve knob after each turn. Stop turning the bonnet nut when the valve knob is loose and turns easily.

Things You Will Need

  • Adjustable wrenches


  • Prevent shutoff valves from freezing or becoming stiff by turning the valve on and off twice a year.
  • Place a folded piece of paper towel on the adjustable wrench jaws or wrap it around the shutoff valve prior to moving the bonnet nut to avoid scratching the metal surface.
