Most homeowners can change a showerhead without any difficulty, except for homes with old plumbing. It's not necessary to hire a plumber to replace your showerhead. Old showerheads can leak invisible, sending water into walls or wasting water down the drain. This can lead to expensive monthly bills. These steps will help you swap out an old, corroded or boring showerhead.
Take out the current showerhead
This is the most difficult step. A homeowner should be able to determine if they require assistance from a plumber at this point. You can inspect the showerhead by gently unscrewing it by hand. Use a wrench to tighten the bolt at the base of the showerhead if it has a rotating feature to adjust pressure or spray patterns. To get leverage, grab the pipe that is attached with one hand. If the showerhead is stuck or rusted, a plumber will be needed to fix it. However, any fixture that is loose should be removed with just a few twists to the left.
Clean the shower arm
Most likely, the pipe or arm that holds the showerhead is covered in visible mineral buildup or rust. Any scale buildup or rust on the threads of the pipe should be removed. Consider having a plumber replace the pipe if it is covered with scale. You should ensure that the threads are free of mineral buildup. This will cause leaks and interfere with tight fittings.
Attach the new shower head
Wrap the threads with a few layers of Teflon plumbing taps once they are clean. When the fittings are screwed together, this creates a watertight seal. Place the new showerhead on the threads, and then tighten the fixture. If the showerhead tilts to one side, be aware of cross-threading. For handheld showerheads, you can simply attach the hose end to the fitting and then the head to the other end. If there are drips, test the showerhead and replace it if necessary.
