How to Fix a Leaky Shower Head

A leaky shower head in Lancaster, Ohio, is almost always caused by a worn rubber washer, a clogged inlet screen, or a loose threaded connection - and you can usually fix it yourself in under 30 minutes with a wrench and a $3 part. If the drip continues after tightening and cleaning, the issue is likely inside the shower valve, which is a job for a licensed plumber. This guide walks you through the exact steps we use on service calls across Fairfield County, from diagnosing the leak to replacing the head, and explains when a repair is smarter than a replacement.

We are Lancaster Hocking Flow Plumbing, and we have fixed hundreds of shower heads in homes from the Sixth Ward to Pleasant Township. Most of those calls could have been resolved with a five-minute DIY fix. The rest needed a valve rebuild or a new trim kit. Here is how to tell the difference before you spend money.

Why Your Shower Head Leaks in Lancaster, Ohio

Shower head leaks in Lancaster, Ohio, trace back to three main culprits: mineral buildup from our hard well and city water, worn seals inside the head, and pressure swings from older plumbing systems. The leak location tells you which one you are dealing with.

If water drips from the spout when the shower is off, the problem is usually the shower valve cartridge, not the head itself. If water sprays sideways from where the head screws onto the arm, it is a missing or degraded washer. If the spray pattern is weak and uneven with a constant drip, the inlet screen is clogged with calcium - a common issue in Lancaster homes built before 1980 that still have galvanized supply lines.

Hard water is the biggest factor here. Lancaster water averages 8 to 12 grains per gallon of hardness, which is high enough to scale up a shower head in 12 to 18 months. That scale eats rubber washers and narrows the flow channels until the head cannot seal properly.

We also see pressure-related leaks in homes near the Lancaster Camp Ground and along the Hocking River floodplain, where older pipes expand and contract with seasonal temperature shifts. A shower head that only leaks in winter is often a pressure issue, not a failed part.

Tools and Materials You Will Need

You do not need a full plumbing kit to fix a leaky shower head. Here is what we carry on every call and what you should have on hand:

• Adjustable wrench or channel-lock pliers
• New rubber washer or O-ring (match the size to your shower head brand)
• Teflon tape (PTFE thread seal tape)
• White vinegar and a plastic bag for descaling
• A small wire brush or old toothbrush
• Replacement shower head if the old one is cracked or beyond cleaning

If you are replacing the head, buy a model with a brass or stainless steel ball joint. Plastic joints fail faster in Lancaster's hard water. A basic replacement head costs $15 to $40 at any local hardware store. A handheld model with a hose runs $25 to $60.

For homes with a shower valve leak - where water drips from the tub spout when the shower is off - you will also need a replacement cartridge. Those cost $20 to $80 depending on the brand. We stock Moen, Delta, and Kohler cartridges on our trucks because those are the three brands we see in 80% of Lancaster homes.

Step-by-Step: How to Fix a Leaky Shower Head in Lancaster OH

Follow these steps in order. Most leaks resolve at step 3 or 4.

1. Turn Off the Water and Remove the Shower Head

Close the shower valve so no water flows. If your home has a dedicated shutoff for the bathroom, use it. Otherwise, turn off the main water supply. Unscrew the shower head from the arm by hand or with an adjustable wrench. Wrap the wrench jaws with tape to avoid scratching the finish.

2. Inspect the Washer and Inlet Screen

Look inside the threaded end of the shower head. You should see a rubber washer and a fine mesh screen. If the washer is cracked, flattened, or missing, that is your leak. If the screen is white or crusty, it is clogged with calcium. Soak the screen in white vinegar for 30 minutes, then scrub it with a toothbrush.

3. Clean or Replace the Washer

Replace the washer if it is deformed. A new washer costs less than $1. If you cannot find an exact match, a universal shower head washer works for most standard 1/2-inch fittings. Do not reuse a washer that has hardened - it will not seal.

4. Apply Teflon Tape and Reattach

Wrap Teflon tape clockwise around the threads of the shower arm - two to three turns is enough. Screw the shower head back on by hand until snug, then give it a quarter turn with the wrench. Do not overtighten; you can crack the plastic housing or strip the threads.

5. Test for Leaks

Turn the water back on and run the shower for 60 seconds. Check the connection point and the spray face. If water still drips from the head when the valve is off, the problem is the valve cartridge, not the head. That is when you call us for shower and bathtub services Lancaster OH.

If the leak is at the base of the shower arm where it enters the wall, you may have a failed drop ear elbow or a cracked pipe behind the tile. That is a hidden leak, and we handle those with leak detection and repair Lancaster OH before any tile gets opened up.

How Much Does Shower Head Replacement Cost in Lancaster OH?

Typical 2026 pricing in this area runs $75 to $150 for a professional shower head replacement, including the part and labor. If you supply your own head, expect $60 to $100 for the install. A full shower valve replacement - which requires opening the wall - costs $350 to $800 depending on access and tile work.

DIY replacement costs $15 to $60 for the head and about 20 minutes of your time. That is the route we recommend for a simple threaded connection. But if the leak is behind the wall or the valve is failing, DIY turns into a $2,000 water damage repair fast. We have seen that happen in Lancaster homes where a slow drip ran behind the tile for months.

Common Mistakes to Avoid

Most failed DIY shower head repairs come down to four mistakes. Avoid these and you will save yourself a second trip to the hardware store.

• Overtightening the head. Plastic threads strip easily. Hand-tight plus a quarter turn is all you need.
• Reusing a hardened washer. If it does not flex, it will not seal. Replace it.
• Skipping the Teflon tape. Tape fills the tiny gaps in the threads that water finds under pressure.
• Ignoring a valve leak. If water drips when the shower is off, the head is not the problem. Replacing it will not stop the drip.

One more thing: do not use pipe dope on a shower head connection. It makes future removal difficult and can clog the screen. Teflon tape only.

If you are dealing with a leak that has already caused water stains on the ceiling below, stop and call us. That is a sign of a failed pan liner or drain connection, not a shower head issue. We see this often in older two-story homes near downtown Lancaster where the original cast iron drains are still in service.

When to Call a Professional

Call a licensed plumber when the leak continues after you have replaced the washer and tightened the connection, when water drips from the tub spout with the shower off, or when you see water damage on the wall or ceiling. Those point to a valve cartridge, a failed mixing valve, or a pipe leak behind the tile.

Frequently Asked Questions

How do I fix a leaky shower head in Lancaster OH?

Turn off the water, unscrew the shower head, and check the washer and inlet screen. Replace a cracked washer, soak a clogged screen in vinegar, wrap the threads with Teflon tape, and reattach. That fixes 8 out of 10 leaks in under 30 minutes.

Why is my shower head leaking in Lancaster Ohio?

Hard water is the usual cause. Lancaster water runs 8 to 12 grains per gallon, which scales up washers and screens in 12 to 18 months. The leak is either at the threaded connection or inside the valve if water drips when the shower is off.

Should I replace or repair a leaky shower head in Lancaster?

Repair if the head is under 5 years old and the leak is at the connection. Replace if the housing is cracked, the spray face is scaled shut, or the head is a cheap plastic model. A new head costs $15 to $60 and takes 10 minutes to install.

How much does shower head replacement cost in Lancaster OH?

Professional replacement runs $75 to $150 in 2026, including the part. If you supply the head, labor is $60 to $100. A full valve replacement behind the wall costs $350 to $800 because it involves opening and patching the wall.

Can a leaky shower head raise my water bill?

Yes. A shower head dripping once per second wastes about 8 gallons a day, or 240 gallons a month. At Lancaster's current water rates, that adds roughly $3 to $6 per month - more if the leak is a steady stream rather than a drip.
