Removing a broken stem can be challenging, but here are some steps you can follow:
Identify the type of stem: Before attempting to remove the stem, you need to identify the type of stem you are dealing with. If the stem is made of metal, you may need to use a different technique than if the stem is made of wood or plastic.
Use pliers: If the stem is protruding from the surface, you can use pliers to grip it firmly and pull it out. Make sure to wear protective gloves to avoid any injury.
Use a screwdriver: If the stem is broken off at the surface, you can try using a screwdriver to pry it out. Place the tip of the screwdriver under the broken stem and gently twist it to lift the stem out.
Use a drill: If the stem is firmly embedded in the surface, you may need to use a drill to remove it. Select a drill bit that is slightly smaller than the diameter of the stem and drill into the center of the stem. Then, use pliers or a screwdriver to twist and pull the stem out.
Seek professional help: If you are unsure about how to remove the broken stem, or if the stem is located in a delicate area, it is best to seek professional help from a plumber, electrician, or other professional who has experience with stem removal.
Remember to take necessary precautions, such as wearing protective gloves and eyewear, and turn off any power sources if necessary before attempting to remove the broken stem.
