Common Showerhead Problems and How to Fix Them
1. Leaking Showerhead
A leaking showerhead wastes both water and money — sometimes up to 500 gallons a year. Start by checking the connection between the shower arm and head. Tighten it gently with an adjustable wrench. If that doesn’t help, remove the showerhead and wrap the pipe threads with Teflon (plumber’s) tape for a better seal.
If the leak persists, the washer or O-ring inside may be worn out. Replacing these small rubber parts often resolves the issue instantly. Persistent leaks, however, can point to a deeper valve problem behind the wall — that’s when calling a licensed plumber makes sense.
2. Low Water Pressure
Low pressure can make your shower feel more like a drizzle than a rinse. First, determine if it’s only your shower or the entire house. If it’s isolated, mineral buildup is often the culprit. Soak the showerhead overnight in a 1:1 vinegar and water solution to dissolve limescale.
If cleaning doesn’t help, the flow restrictor (a small plastic disk designed to conserve water) might be overly restrictive — removing or adjusting it can improve pressure. If your whole home has low water pressure, you might need to adjust the pressure regulator or check for plumbing obstructions.
3. Clogged Showerhead
Houston’s hard water can cause calcium and lime buildup inside shower nozzles. To unclog, unscrew the showerhead and soak it in white vinegar for several hours. Scrub with a soft brush or toothpick to remove debris. If the clog is severe, you may need to use a plumbing snake to clear internal passages.
Sometimes, a replacement showerhead is the best option — especially if the old one is heavily corroded or inefficient.
4. Uneven or Weak Spray Pattern
When your shower sprays unevenly or at odd angles, it’s usually due to mineral deposits blocking the nozzles. Cleaning the faceplate or soaking it in vinegar can help restore the correct spray pattern.
If your showerhead offers multiple spray settings, rotate the selector to ensure it’s not stuck. When cleaning doesn’t fix it, replacing the showerhead may give you better water efficiency and comfort.
5. Broken Shower Arm
A cracked or broken shower arm is a bit more complex to handle. Turn off the water supply, remove the old arm using an adjustable wrench, and clean the threads inside the wall pipe. Apply plumber’s tape and install the new shower arm by hand-tightening it before giving it a final snug twist with the wrench.
If you notice corrosion or damaged threads in the pipe behind the wall, it’s best to call a professional plumber. DIY attempts in these cases can cause leaks inside the wall — leading to water damage and mold growth.
6. Dripping Showerhead After Shutoff
If your showerhead keeps dripping after you turn off the faucet, the valve cartridge may be worn out. The valve controls water flow inside the wall and can deteriorate over time, especially in older Houston homes.
Replacing a valve cartridge typically requires removing the handle and trim, shutting off the water, and accessing the valve assembly. Because of the precision needed, most homeowners prefer letting a professional plumber handle this repair safely.
Step-by-Step Showerhead Maintenance Plan
- Monthly: Wipe down the showerhead and check for leaks.
- Quarterly: Soak in vinegar to remove mineral buildup.
- Annually: Replace worn washers or O-rings.
- As needed: Upgrade to a high-efficiency showerhead to conserve water and maintain strong flow.
Routine maintenance not only improves water pressure but also extends your showerhead’s lifespan and reduces your utility bills.
When to Call a Professional Plumber
While basic cleaning and tightening are safe for DIY, call a licensed Houston plumber if you notice:
- Persistent leaking behind the wall or at the valve
- Fluctuating water pressure throughout the house
- Corrosion or rust around fittings
- Drips that continue even after valve replacement

Yes, white vinegar is safe and effective for removing hard water buildup. Just avoid soaking rubber or plastic parts for more than a few hours.
