Shower head leaking at threads

Shower leaking at thread

My leaking shower head is driving me nuts.

You can see a short video of it here

A leaking shower head is frustrating for anyone especially if you have it constantly dripping even when the shower isn’t in use.

Fortunately for me, mine only drips when I’m actually using the shower so at least I’m not constantly wasting water. The really annoying part though is it means the jet of water isn’t so strong as I’m losing pressure due to the leak.

With the price of all utility bills going through the roof currently, anyone on a water metre should not be leaving dripping shower heads unfixed for any length of time.

Also, apart from the wasting of water and money the constant dripping sound can be very annoying.

One of the common causes of shower head leaks is at the threads and as you can see on the video that is exactly where mine is dripping from.

In this article, I share what I’ve learnt about the causes of shower head leaks at the threads and provide a step-by-step guide on how to fix this issue.  

Let me state upfront I’m not a qualified plumber (far from it) but I like to try and fix things for myself so I researched the internet and YouTube to see what I can find.

So here I will provide some tips on preventing future leaks and when it’s appropriate to call a professional plumber for help.

Introduction: Understanding the Problem

If you’ve noticed that your shower head is leaking at the threads, you’re not alone. After minimal research I found this is a very common problem that can be caused by a variety of issues.

Apart from being annoying and wasteful, small issues like this can develop into bigger problems if left unchecked. So, in this article, I’ll go over the common causes of shower head leaks at the threads, how to detect them, and, most importantly, how to fix them.

Overview of Shower Head Leaks

Shower head leaks can occur for a variety of reasons, including worn out parts, loose connections, and damage to the head itself. A leak at the threads is particularly common, as this is where the head attaches to the water supply.

If you use your shower every day, as I do, overtime the wiggling round of the head at the point where it meets the hose causes wear and tear.

Where they meet is a weak spot so if ever there is a problem it will always be the most likely culprit.

Consequences of Ignoring a Leaking Shower Head

Ignoring a leaking shower head can lead to several problems. As already mentioned, it wastes water and can increase your water bills.

If it drips constantly the drips can cause damage to your bathroom walls if left unchecked for a long time.

Additionally, the constant moisture from a leak can lead to mould growth, which can be hazardous to your health*.

* Mould in homes can cause health issues. Usually respiratory in nature and often start with nasal congestion, sneezing, coughing, wheeziness etc. So if you have young children or elderly relatives any mould can be serious.

Common Causes of Shower Head Leaks at Threads

Loose Connections

One common cause of a leaking shower head at the threads is loose connections. Over time, the connections between the shower head and water supply can wear down, causing water to seep through.

This can easily be fixed by tightening the connections, though don’t overdo it. As you might do more damage.

Worn Out Threads

If your shower head has been in use for several years, the threads may have worn down, causing a leak. This I think was the case for me. I’ve lived here 12 years and the shower was here when I moved in, so who knows how old it might be!

In this scenario you may need to replace the shower head entirely. (More on this later)

Cracked or Damaged Shower Head

Another cause of a leaking shower head is a cracked or damaged head. Over time, shower heads can become brittle due to the constant exposure to water and heat, causing cracks and leaks. In this case, a replacement may be necessary.

How to Detect a Leak at the Shower Head Threads

Visual Inspection

One of the easiest ways to detect a leak at the shower head threads is through a visual inspection. Check the area where the shower head screws onto the water supply and look for any signs of water or moisture. If you see any, it’s likely that you have a leak.

Listening for Dripping Sounds

If you’re having trouble spotting the leak, trying listening for any dripping sounds while the shower is turned off. If you hear any dripping, it’s a good indication that you have a leak at the shower head threads.

Feeling for Moisture

You can also feel around the shower head threads for any signs of moisture. Run your fingers over the area where the head connects to the water supply and check for any dampness.

Step-by-Step Guide to Fixing a Leaking Shower Head

Gathering Necessary Tools and Supplies

To fix a leaking shower head at the threads, you’ll need a few basic tools and supplies, including an adjustable wrench, pliers, and Teflon tape.

Removing the Shower Head

Using the adjustable wrench and pliers, remove the shower head from the water supply to access the threads. Be sure to place a rag or tea towel over the pliers to protect the finish on the shower head.

Replacing and Tightening the Teflon Tape

Wrap a new layer of Teflon tape around the threads, making sure to wrap it in a clockwise direction. This will help prevent any further leaks. Carefully screw the shower head back onto the water supply and tighten it using the wrench and pliers, making sure not to over-tighten.

Reinstalling the Shower Head

Finally, turn on the shower and test for any leaks. If you notice any leaks, repeat the process and make sure the Teflon tape is wrapped tightly and correctly. If the leak persists, you may need to replace the shower head entirely.

Additional Tips for Preventing Shower Head Leaks

No one wants to deal with a leaking shower head. Luckily, there are a few things you can do to help prevent this problem from recurring. Here are some additional things to consider:

Regular Cleaning and Maintenance

Cleaning your shower head regularly can help prevent the build-up of mineral deposits and other materials that can cause leaks. Use a soft brush or cloth to wipe away any residue, and make sure to rinse the head thoroughly afterward.

You can also soak your shower head in a mixture of vinegar and water to help dissolve stubborn build-up.

Using Teflon Seal Tape

Thread seal tape or Teflon, also known as plumber’s tape, is an inexpensive and easy way to prevent leaks at the threads of your shower head.

Simply wrap the tape around the threads before screwing on the head to create a watertight seal.

When to Call a Professional Plumber for help

While these tips can help prevent most shower head leaks, there are some situations where you may need to call in a real plumber to help fix the problem. Here are some signs that it’s time to seek assistance:

Excessive Water Leakage

If your shower head is leaking a significant amount of water, it’s likely that there’s a more serious problem at play. A plumber can diagnose the issue and make the necessary repairs to stop the leak.

Damaged or Cracked Pipes

If you notice any damage or cracks in your plumbing pipes, it’s important to have them repaired as soon as possible. Even small cracks can lead to significant leaks and water damage over time.

Deteriorated Plumbing System

If your home’s plumbing system is old or deteriorating, it may be time to consider a full replacement. A professional plumber can provide advice and guidance on the best course of action for your situation.

Repair or Replace Shower Head?

Sometimes it works out cheaper to replace something rather than to try and fix or repair it yourself. After doing a pretty good job of repairing my leaking shower head I started to think I maybe should have just replaced the shower head and hose due to the age of them.

I was proud of myself for making the repair, but about a month later I took the plunge and bought a new one. There comes a point where things have just done as much as they can!

Conclusion: Enjoying a Leak-Free Shower Experience

With regular maintenance and the right tools, you can enjoy a leak-free shower experience. Remember to clean your shower head regularly, use Teflon seal tape, and avoid over-tightening to prevent leaks.
