Why Your Shower Head or Tub Spout Keeps Dripping (and When to Call a Plumber in Encinitas)

Common Causes of Shower and Tub Spout Drips in North County Homes

If your shower head or tub spout keeps dripping even after the water is turned off, it’s usually a sign that something inside the valve isn’t sealing properly. While it may seem minor, a constant drip can waste water, increase utility bills, and indicate wear inside your plumbing system.

At Encinitas Plumbing, we regularly diagnose these issues as part of our shower repair services in Encinitas, and we often find that the root cause goes beyond just a worn part.

What Causes a Shower Head or Tub Spout to Drip?

Worn Shower Valve Cartridge

Most modern shower valves use a cartridge to control water flow and temperature. Over time, these cartridges wear out or become damaged.

Signs of a failing cartridge:

• Dripping from the shower head or tub spout
• Difficulty adjusting temperature
• Stiff or loose handle movement

When the cartridge can no longer seal properly, water continues to pass through even when the valve is “off.”

High Water Pressure (Common in Encinitas)

One of the most overlooked causes of dripping shower heads is excessive water pressure.

High pressure:

• Puts stress on valve component
• Accelerates wear on cartridges and seal
• Can cause repeated failures even after replacement

In many homes throughout Encinitas and North County, pressure regulators either fail or are set too high. If your home has elevated pressure, it may be time to consider a water pressure regulator installation or replacement to protect your plumbing system.

This is why simply replacing a cartridge doesn’t always solve the problem long-term.

Mineral Buildup from Hard Water

Local water conditions can also contribute to valve failure.

Hard water can:

• Build up inside cartridges
• Prevent proper sealing
• Cause internal components to degrade faster

This often leads to recurring leaks and reduced performance over time. Installing a whole-house water treatment system can help reduce mineral buildup and extend the life of your plumbing components.

Worn Valve Seals or Internal Components

In some cases, the issue goes beyond the cartridge and involves:

• Internal valve body wear
• Damaged seals
• Older or failing fixtures

This is more common in aging systems or lower-quality installations.

Why Replacing the Cartridge Isn’t Always Enough

A common mistake is assuming:

“Just replace the cartridge and it’s fixed.”

In reality, if the underlying cause—like high water pressure —isn’t addressed, the new cartridge may fail again prematurely.

At Encinitas Plumbing, our shower valve repair service includes a full diagnostic approach:

• Measuring water pressure
• Inspecting valve components
• Identifying contributing factors

Our Approach to Shower Valve Repair

When we troubleshoot a dripping shower or tub spout, we don’t guess—we diagnose.

Our process includes:

• Checking system water pressure
• Inspecting the valve and cartridge condition
• Identifying mineral buildup or wear
• Recommending the correct repair or replacement

If high pressure is found, we may recommend a pressure regulator replacement to prevent ongoing damage.

When to Call a Plumber

You should have your shower valve inspected if:

• The shower head or tub spout continues to drip
• You’ve already replaced the cartridge and the issue returned
• Water pressure in the home seems high
• The handle is difficult to turn or inconsistent

Ignoring the issue can lead to:

• Wasted water
• Higher utility bills
• Premature failure of plumbing components
