You can replace a shower head with basic hand tools: hold the shower arm steady, unscrew the old head, clean the threads, seal them if the new head’s sheet calls for it and hand-tighten the new head. Three problems turn the job into a plumbing call: a head that will not turn without twisting the arm, a leak at the wall or flange, and a drip after the valve closes. Bienvenu Brothers repairs and replaces shower fixtures in Metairie, New Orleans and the surrounding communities. Our BBB A+ Rated, 4th generation family-owned company is 100% recommended on Facebook, Loved Locally on Nextdoor and an Angi Super Service Award winner. We work under Louisiana master plumber license LMP#7214WSPS, stay fully insured and have served South Louisiana since 1937. Contact Bienvenu Brothers or call (504) 835-7783 to schedule shower repair.
This guide gives the eight steps, shows how to loosen a stuck head without damaging the arm, explains why new heads leak and flags the signs that point to a problem inside the wall. Local water data for Metairie and New Orleans closes the guide.
What Shower Head Replacement Involves
A shower head threads onto the shower arm, the pipe that stubs out of the wall. A rubber washer or O-ring inside the head seals the connection, and some installations add plumber’s tape to the arm threads. Replacement swaps the head only. It leaves the valve behind the wall alone, which is a separate job that our guide to replacing a shower faucet covers.
Homeowners replace a head when the nozzles clog with mineral deposits, when the connection leaks, when the spray no longer suits the household or when a handheld model improves access. EPA reports that showering accounts for nearly 17 percent of residential indoor water use, so the head you choose deserves a moment of thought.
Match the fix to the problem. A vinegar soak solves a clogged head, a new washer solves many connection leaks and a replacement solves a damaged head or a spray you no longer like. A plumber handles anything at the arm, the flange or the valve.
What Makes a Shower Head Stick, Leak or Clog
Six causes explain most stuck or leaking shower heads.
- Mineral scale. Calcium and magnesium in hard water crystallize on the threads and inside the nozzle holes. Scale locks the connection and narrows the spray.
- Corrosion at the joint. Constant moisture corrodes the metal where the head connector meets the arm, and a seized joint will not turn by hand.
- Over-tightening. Extra force flattens the washer and strains the arm. Moen’s handheld installation guide warns against overtightening.
- A worn washer or O-ring. Rubber hardens and cracks over time, and EPA suggests checking the washer or O-ring inside the head and replacing it if needed while you replace a head.
- The wrong sealing method. Some heads seal at the washer and the manufacturer does not want tape, while others rely on tape on the arm threads. Moen’s handheld guide recommends against thread seal tape for that product. Read the sheet that came with your head.
- Damaged threads or a loose arm. Crooked or stripped threads leak at the joint, and an arm that has worked loose in the wall fitting leaks at the flange.
Moisture also feeds mold and biofilm, because nozzles hold water between showers. EPA states that the key to mold control is moisture control.
Signs Your Shower Head or Shower Arm Needs Attention
- Uneven or weak spray. Scale blocks nozzle holes, so water sprays sideways or thins out.
- A drip at the connection while the shower runs. The washer, the tape or the thread seal needs attention.
- A drip from the head after you shut off the valve. A few drops are normal as the head drains. A steady drip points to a worn valve cartridge, not the head.
- Water at the flange, or stains on the wall or ceiling below. The leak sits behind the wall. Stop using the shower and call us.
- An arm that wobbles or turns. The arm has loosened in the wall fitting.
- Black or slimy residue in the nozzles. Mold or mildew grows where water sits. Clean the head or replace it.
- Rust-colored flakes at the head. Corrosion in the arm or the head connector is shedding.
- A head that will not unscrew. Scale or corrosion has locked the threads, and the stuck head steps below apply.
Shower Head Replacement: DIY or Professional?
Most head swaps suit a careful homeowner. Anything that involves the arm, the wall or the valve calls for a plumber.
| Task | Reasonable for a DIYer | Call a professional when |
|---|---|---|
| Swap a head that unscrews by hand | Yes | The arm moves or wobbles as you turn |
| Clean a clogged head with vinegar | Yes | Residue returns quickly after cleaning |
| Free a stuck head | Yes, while the arm stays still | The arm turns, or soaking and lubricant do not free the head |
| Replace a worn washer or O-ring | Yes | The leak continues with a new washer and clean threads |
| Replace the shower arm | Possible for a confident DIYer | The arm has seized in the wall fitting or tile blocks access |
| Fix water at the flange or on the wall | No | Always, because the leak sits inside the wall |
| Stop a drip after the valve closes | No | Always, because the cartridge or valve needs repair |
| Install a handheld set with a diverter | Yes, with the manufacturer guide | Local code calls for backflow protection you cannot confirm |
How to Replace a Shower Head: Tools, Steps and Fixes
Tools and Materials
- An adjustable wrench or channel-lock pliers, with the jaws wrapped in plumber’s tape or a cloth to protect the finish
- Plumber’s tape, unless the new head’s sheet says not to use it
- A soft cloth and a towel or garbage bag for the tub
- The replacement head, with its washer or O-ring
- White vinegar, a plastic bag and a rubber band for scale
- Steel wool or an old toothbrush for the arm threads
Replace the Shower Head in 8 Steps
- Protect the tub. Lay a towel or garbage bag over the drain and tub floor to catch tools, scale and old tape.
- Loosen the old head. Hold the shower arm steady with one hand and turn the head counterclockwise. If it resists, wrap the wrench jaws in tape or a cloth, grip the connector nut and turn counterclockwise. Never use the arm as a lever.
- Remove the old head and tape. Unscrew the head by hand once it breaks free, then peel off any plumber’s tape left on the arm, as the American Standard guide directs.
- Clean the arm threads. Scrub deposits off the threads with steel wool or an old toothbrush, then wipe the arm with vinegar. Hunker’s guide uses the same steel wool and vinegar cleanup.
- Flush the arm. With the head off, turn the shower on for a few seconds so water pushes loose scale out of the arm, then turn it off.
- Seal the threads. Check the new head’s sheet. If it calls for tape, wrap plumber’s tape clockwise around the arm threads, the direction the head tightens. If the sheet says not to use tape, rely on the washer.
- Thread on the new head. Make sure the washer sits flat in the connector, start the head by hand to avoid cross-threading, then snug it with a cloth-wrapped wrench only if the manufacturer allows a tool. Do not overtighten.
- Test the connection. Run the shower for a minute, dry the joint with a towel and look for fresh moisture. Snug the head slightly if it drips, and check again after the first day.
Remove a Stuck Shower Head Without Damaging the Arm
A stuck head is usually scale or corrosion, not a defective part. The goal is to break the bond at the connector while the arm stays still.
- Support the arm. Hold the arm near the wall with your hand or a second wrench so it cannot turn. A twisted arm strains the fitting inside the wall.
- Soak the joint in vinegar. Fill a plastic bag with white vinegar, slide it over the head so the connection sits in the vinegar and secure it with a rubber band. Hunker suggests several hours or overnight.
- Add a penetrating lubricant. Spray a lubricant such as WD-40 at the joint, wait, and keep it off skin and eyes.
- Grip and turn. Wrap the wrench jaws in tape or a cloth, grip the connector nut and turn counterclockwise with steady pressure.
- Stop if the arm moves. If the arm starts to turn, stop and call us. A twisted arm can damage the fitting behind the wall.
Peerless states that a 50/50 mix of white vinegar and water removes deposits without harming the finish on its products, so read the care sheet for your head before you use anything stronger. Call a plumber if soaking and lubricant do not free the head or if the arm moves at all.
Fix a Leak at the Shower Head Connection
| What you see | Likely cause | Fix |
|---|---|---|
| Drip at the connection nut while the shower runs | A missing, dry or cracked washer, or a thread seal that does not match the sheet | Replace the washer, reseat the head and reseal the threads as the sheet directs |
| Spray from the joint | Crooked or damaged threads | Remove the head, inspect the threads and replace the head or the arm |
| Drip at the ball joint of an adjustable head | A worn seal inside the joint | Replace the head |
| Leak where the hose meets a handheld head | Absent or worn hose washers | Replace the washers and hand-tighten, as Moen directs |
| Water at the flange or stains on the wall | A loose arm fitting or a joint inside the wall | Stop using the shower and call us |
| Steady drip after the valve closes | A worn cartridge or valve seat | Repair or replace the cartridge, which is a plumber task |
| A few drops after the shower ends | Normal drain-down of water held in the head | No repair needed unless the drip continues |
Faucets leak for similar reasons, and our list of common faucet problems and repairs you can do covers the sink side.
Choose the Right Replacement Head
Flow rate comes first. EPA says that standard showerheads use 2.5 gallons per minute and that a WaterSense labeled head must demonstrate use of no more than 2.0. Pick the spray pattern for the feel you want, and our guide to choosing a shower head when pressure runs high helps match the head to your pressure.
| Option | Good fit when | Watch for |
|---|---|---|
| Fixed head on the existing arm | You want a simple swap | Thread seal method and flow rate |
| Adjustable head on a ball joint | Family members have different heights | A worn ball joint seal that leaks over time |
| Handheld set on a bracket | You bathe children or pets, or shower seated | Backflow protection under local plumbing code and worn hose washers |
| Rain-style head on a long arm | You want a wider, softer spray | A new arm and flange, which can turn into a plumbing job |
Most standard heads thread onto a standard shower arm, while heads with a built-in arm or a custom mount follow their own instructions. A handheld set adds reach for anyone who needs it. Moen’s handheld guide says to install its product with a backflow preventer as local plumbing code requires, and Louisiana’s plumbing rules sit in the Louisiana State Uniform Construction Code. We check code requirements before we install a handheld set.
Shower Head Care in Metairie, New Orleans and Nearby Communities
Four local factors shape how long a shower head performs well here. The table shows what each looks like and what it means for your bathroom.
| Local factor | What the data shows | What it means for your shower head |
|---|---|---|
| Water hardness | Jefferson Parish’s 2025 water quality report lists total hardness of 75.7 to 190 ppm on the East Bank and 81 to 190 ppm on the West Bank. The USGS scale places that range between moderately hard and very hard. The S&WB report for Orleans Parish lists no hardness figure. | Scale clogs nozzles and locks threads. A periodic vinegar soak keeps nozzles clear, and our guide to water softeners for hard water in New Orleans explains whole-home options. |
| Humidity | Bathrooms in southeast Louisiana stay damp, and nozzles hold water between showers. | Run the exhaust fan during and after showers, and clean the nozzles when residue appears. |
| Older homes | Homes across Metairie, New Orleans, Kenner and Harahan span many decades of construction. | Original arms and fittings may be decades old. A corroded arm can seize in its wall fitting and turn a simple swap into a plumbing job. |
| Water bills | EPA lists showerheads among the first places to check for household leaks. | A dripping head runs around the clock. If you suspect more than one leak, follow our guide to a high water bill and hidden leaks. |

Shower Head Replacement FAQs
These are the questions Metairie and New Orleans homeowners ask us most often about replacing a shower head.
How do I replace a shower head step by step?
Protect the tub, then loosen the old head while you hold the shower arm steady. Remove the old tape, clean the arm threads, flush the arm for a few seconds and seal the threads with plumber’s tape if the new head’s sheet calls for it. Thread the new head on by hand, snug it without overtightening and run the shower to check the connection. The full eight-step version appears earlier in this guide, and the American Standard installation guide covers the same basic swap.
What tools do I need to replace a shower head?
You need an adjustable wrench or pliers, plumber’s tape, a soft cloth to protect the finish, a towel for the tub and the replacement head. White vinegar and a plastic bag help with scale, and steel wool or an old toothbrush cleans the threads. Hunker’s stuck shower head guide adds a penetrating lubricant to the list. A head swap does not strictly require shutting off the water, and Hunker recommends it if you have little plumbing experience.
Do I need plumber’s tape to install a shower head?
Follow the sheet that came with the head. The American Standard guide lists plumber’s tape among its two tools and applies new tape to the shower arm. Moen’s handheld shower guide recommends against thread seal tape for that product. When tape applies, wrap it clockwise around the arm threads, the direction the head tightens, and remove any tape that squeezes out.
How tight should a shower head be?
Hand-tight, then snug. Thread the head on by hand so it seats straight, and add a small turn with a cloth-wrapped wrench only when the manufacturer allows a tool. The American Standard guide says to tighten with a wrench if necessary to prevent leaks, and Moen’s handheld guide says not to overtighten. Extra force flattens the washer and strains the arm inside the wall.
Why will my shower head not unscrew?
Scale and corrosion lock the threads. Calcium and magnesium from hard water crystallize in the joint, and constant moisture corrodes the metal until the connector bonds to the arm. A soak in white vinegar, a penetrating lubricant and a cloth-wrapped wrench usually break the bond. Hold the arm still while you turn, and stop if the arm moves.
How do I remove a stuck shower head without damaging the shower arm?
Support the arm with your hand or a second wrench, soak the joint in white vinegar for several hours or overnight, spray a penetrating lubricant on the threads and turn the connector nut counterclockwise with a wrench wrapped in tape or cloth. Hunker’s guide covers the soak, lubricant and wrench steps, and holding the arm still is the added precaution that protects the fitting in the wall. Never use the arm as a lever. If the arm turns in the wall, stop and call us, because a twisted arm can damage the fitting behind the wall.
Why does my new shower head leak at the connection?
The usual causes are a missing or cracked washer, tape applied against the manufacturer’s directions, threads that sit crooked, or a head that is slightly loose. Remove the head, inspect the washer, clean the threads, reseal them as the sheet directs and tighten by hand. EPA suggests checking the washer or O-ring inside the head, and replacing it if needed, while you replace a head. A leak that continues points to damaged threads on the head or the arm.
Why is water leaking behind the shower arm or from the wall?
Water at the flange, the plate where the arm meets the wall, or stains on the wall or ceiling below point to a leak inside the wall, such as a loose arm fitting or a supply pipe joint. Stop using the shower and call us. Our water leak detection and repair service locates leaks behind tile and drywall, and our guide to shutting off the main water valve helps if water keeps spreading.
Why does my shower head drip after I turn off the shower?
A few drops are normal while the head drains. A steady drip means the valve is not closing fully, usually because of a worn cartridge or seat, and a new head will not fix it. Our guide to troubleshooting hot water issues in your shower explains the valve side, and we repair or replace the cartridge, valve and trim.
How do I clean a shower head instead of replacing it?
Soak it in a 50/50 mixture of white vinegar and water, which Peerless states removes deposits without harming the finish or internal components of its products. Check it periodically, scrub leftover deposits with a toothbrush and rinse. Avoid bleach-based, industrial and abrasive cleaners that can damage finishes, and read your head’s care sheet because finishes differ by brand.
What do black spots on a shower head mean?
Black or slimy spots in the nozzles usually mean mold or mildew growing where water sits between showers. EPA states that the key to mold control is moisture control, so run the exhaust fan during and after showers and clean the nozzles with vinegar. Black flecks can also come from a worn washer. If the residue returns quickly after cleaning, replace the head. Our guide to cleaning mold in showers covers the rest of the stall.
Should I choose a 2.5 gpm or a 2.0 gpm shower head?
EPA reports that standard showerheads use 2.5 gallons per minute and that WaterSense labeled heads must demonstrate use of no more than 2.0. Spray design matters as much as flow rate, so choose the spray pattern first and the labeled flow rate second. Our post on the top 10 ways you’re wasting water shows where else water use adds up at home.
Does a handheld shower head need special parts?
It needs a bracket, a hose with washers and a backflow preventer where local plumbing code requires one. Moen’s handheld guide says to hand-tighten the bracket and the hose washers, to skip thread seal tape and to install the product with a backflow preventer as local plumbing code requires. We check code requirements before we install one. Handheld sets also help with accessibility, as our post on accessible plumbing fixtures explains.
How does hard water in Metairie and New Orleans affect shower heads?
Jefferson Parish’s 2025 water quality report lists total hardness of 75.7 to 190 ppm on the East Bank, and the USGS hardness scale places that range between moderately hard and very hard. Scale builds in nozzles and on threads, which clogs sprays and locks heads onto arms. The S&WB report for Orleans Parish does not list hardness, so use the Jefferson range as a regional reference. A water softener installation reduces scale at every fixture.
When should I call a plumber instead of replacing the shower head myself?
Call when the head will not move without twisting the arm, when water appears at the flange or on the wall or ceiling, when the arm wobbles, when the valve drips after shutoff or when the leak continues after a new washer and clean threads. Our guide on when to call a professional plumbing service covers the wider picture. Call (504) 835-7783 and we schedule a visit.
