Shower heads often spray unevenly because the tiny holes have gotten clogged with mineral deposits. Use an old toothbrush to clean the head. Then run a sharp blast of water backward through the showerhead.

For a thorough cleaning, take the head apart, use a pin or thin wire to poke out any mineral buildup or debris, and brush away all deposits. Then soak the parts in vinegar overnight to dissolve remaining mineral deposits. Reassemble and reinstall the showerhead.

If it leaks at the arm, or if it doesn't stay in position, tighten the retainer or collar nut. If that doesn't work, replace the O-ring or replace the showerhead. If leaks persist, call the professionals at Sun Devil Plumbing.
