Leaking Shower Head? Here’s What You Should Do Next

A leaking shower may seem like a small problem, but each drip wastes water. This can increase your bills and damage tiles, paint, and floors. If you ignore it, that steady leak can cause problems behind the wall. This can lead to mould, rot, and expensive repairs.

At Water Works, our licensed plumbers repair leaking shower heads and hidden leaks before they cause long-term water damage. Here’s how to recognise the signs, understand the causes, and know when to call in the experts.

Common Causes of a Leaking Shower

1. Worn-Out Washers or O-Rings - The tiny rubber washers inside taps and fittings dry out or crack, letting water escape.
2. Faulty Tap Cartridges - Mixer-tap cartridges can clog or wear, preventing a watertight seal.
3. Loose Shower Fittings - Everyday vibration loosens joints, allowing leaks around connections.
4. Cracked Grout or Sealant - Water slipping through failed silicone can create leaking shower walls and hidden rot.
5. High Water Pressure - Excess pressure strains hoses, valves, and seals, accelerating wear.

How to Fix a Leaking Shower

If you’re wondering how to fix leaking shower problems safely, start here:

• Turn Off the Water Supply - Shut the main valve or shower isolation tap.
• Inspect the Shower Head - Unscrew it, clear mineral buildup, and replace any worn rubber washers.
• Check the Tap or Mixer - Remove the handle and inspect the cartridge or spindle; replace damaged parts.
• Re-Seal Around the Shower - Remove cracked grout or silicone and apply new silicone sealant.
• Test for Leaks - Restore the water supply and check every joint.

While these steps can seem straightforward, DIY shower repairs often cause bigger problems if done incorrectly. Using the wrong sealant, over-tightening fittings, or damaging waterproof layers can lead to hidden leaks behind walls, causing mould, water damage, or costly rework later on.

For lasting results, it’s always safer to call a licensed plumber who can identify the source of the problem, repair it properly, and ensure your shower stays watertight for good.
