Why is my Shower Head Dripping?

There’s nothing more annoying than a dripping shower head. It can irritate you by day and even keep you up at night, but there are other problems too. 

 

Over time, a dripping shower head can waste surprisingly large quantities of water. This could increase your water bill, as well as being bad for the planet. 

 

But why is your shower head dripping, and what can you do about it? Read on to find out the common causes of leaky showers and get some handy tips for effective fixes. 

 

A shower head drips when water continues to pass through the fixture even after the valve is turned off. In many cases, this happens because internal components in the shower head or valve are worn out or not sealing properly.

 

To understand why your shower head is dripping, it’s useful to know a little about how your shower system works. 

 

To give you a lovely refreshing shower each morning, your shower system sends controlled water flow through a valve. This valve is connected to the hot and cold water pipes. 

 

When you turn the shower off, the valve should completely close and not let any more water through. If it doesn’t, even slightly, small amounts of water can escape and travel up to the shower head - resulting in that annoying drip.

 

Sometimes the cause of this is simple, and can be easily resolved. But in other cases, it could be caused by more complex issues such as corrosion, mineral buildup or another failed component.

Why Does My Shower Head Drip After Use?

It’s actually quite common for a shower head to drip for a few minutes after use, so don’t panic if this is happening in your bathroom.

 

This is because of two things - residual water and pressure changes. 

 

Residual water means water that is trapped inside the shower head and pipe after use. Gravity slowly pulls it out, causing temporary dripping. 

 

As for pressure changes, this happens when the water flow stops and pressure inside the plumbing system adjusts. This can release small amounts of leftover water. 

 

In either case, the dripping should only last a few minutes. If it goes on for hours or worse still, never fully stops, then you may have a more serious problem on your hands.

Common Causes of a Dripping Shower Head

Persistent dripping is usually caused by one of the following:

 

1. A Worn-Out Shower Cartridge or Valve

Modern showers tend to have a cartridge inside the valve which controls water flow and temperature. Over time, this cartridge can crack, wear down or become clogged with debris. As soon as it no longer seals tightly, water can seep through.

 

2. Damaged Washers or O-Rings

If you have an older shower system, it may have rubber washers or O-rings instead. These do the same job, creating a watertight seal. As these components age, they can become brittle or compressed, allowing water to pass through even when the shower is turned off.

 

3. High Water Pressure

Excessively high water pressure can force water past internal seals, leading to slow but steady dripping. If you’ve noticed other plumbing issues - such as banging pipes or leaking taps - then pressure may be the culprit.

 

4. Mineral Buildup

In areas with hard water, mineral deposits (such as calcium and magnesium) can accumulate inside the valve or shower head. This buildup prevents proper sealing and can cause leaks.

 

5. Faulty Diverter Valve

If your shower shares pipework with your bath taps, a malfunctioning diverter valve may allow water to travel upward and escape through the shower head.

How to Fix a Shower Head Drip

We’ve looked at the potential causes of leaky shower heads, but it’s now time to run through some solutions. 

 

The right fix depends on the cause of the problem, and you might need to get a plumber in to accurately diagnose the issue. 

 

But here are some common fixes for dripping shower heads that you might want to try:

 

  • Tighten the connections - the problem could be as simple as a slightly loose shower head connection, which just needs tightening
  • Replace the shower cartridge - if the internal cartridge is worn, a like-for-like replacement is the best solution (you might need a plumber for this one)
  • Replace washers and/or O-rings - these components are cheap and easy to buy, and you can even replace them yourself with a little bit of DIY knowledge
  • Clean the shower head - soaking the shower head in vinegar for several hours can help to dissolve the mineral buildup. To prevent it happening again, you might want to consider upgrading to a filtered shower head - then all you’d need to do is replace the filter every few months. 
  • Install a pressure regulator - if high water pressure is the issue, installing a pressure-reducing valve (PRV) can protect your entire plumbing system as well as your shower. 

When Should a Leaking Shower Head Be Replaced?

In some severe cases, your shower head can’t be saved through repairs or replacement parts. It’ll need replacing if it’s heavily corroded or mineral buildup keeps returning. If it’s around 10 to 15 years old, it could be time to get a new one. 

 

Remember though, if the leak is caused by the valve inside the wall - not the shower head itself - replacing only the shower head won’t solve the problem. If in doubt, get a trained plumber in to take a look.
