Why Is Your Shower Valve Leaking?

A shower valve controls the flow and temperature of your water. When it leaks, it usually means something is worn out, broken, or installed incorrectly. Here are the most common culprits:

• Worn-out washers or seals: These small parts form a tight seal inside the valve, but they naturally degrade over time. Once they fail, water can seep through, causing that dreaded leak.
• Cartridge damage: Many modern showers use cartridges to manage water flow. If a cartridge cracks or builds up mineral deposits, it can’t seal properly, leading to drips.
• Loose valve connections: Over years of use, pipes and fittings can shift or loosen behind the wall, causing water to escape around the valve housing.
• Corroded parts: Hard water is often to blame for corrosion inside the valve body, which weakens parts and causes leaks.

In rare cases, a poorly installed valve can start leaking almost immediately, especially if shortcuts were taken during remodeling or a DIY project.

When to Call a Professional

A minor drip might seem easy to ignore, but a leaking shower valve is more than a nuisance. It can:

• Waste gallons of water over time
• Drive up your utility bills
• Cause hidden water damage behind your shower wall
• Promote mold growth

If you notice any of these red flags, it’s time to call for help:

• The leak is constant, even with the water turned off
• You see water pooling around the shower floor
• There’s a musty smell or peeling paint near the shower
• You hear water running inside the wall

Experts from Fast Trak Plumbing and Drain can diagnose the leak, repair or replace the valve, and even check the surrounding pipes to keep your bathroom dry and damage-free.

How to Prevent Shower Valve Leaks

While some plumbing failures are unavoidable, you can definitely reduce the risk of a leaking shower valve with these steps:

• Schedule annual plumbing checkups
• Use a water softener to limit hard water damage
• Avoid forcing the handle or turning it too hard
• Keep an eye out for early drips and fix them right away

Simple habits — like gently shutting off the shower and cleaning fixtures regularly — can make a big difference.
