Why Is Water Coming Out of Shower Head and Faucet?

Why Is Water Coming Out of Shower Head and Faucet?

If you’ve ever turned on your bathtub faucet only to find water pouring from the shower head, you’re not alone. Such instances can perplex many homeowners.

The main factors that might cause this issue are valve malfunction, worn-out parts, or incorrect plumbing installation.

In this article, we will delve into the reasons behind this common plumbing problem and how to fix it.

Common Scenarios of Simultaneous Water Flow

Ah, I remember it like it was yesterday. I had just returned from a long day at the office, dreaming of a soothing warm bath.

Turning on the faucet, I noticed water inexplicably streaming from the showerhead. My friends, this is a classic example of simultaneous water flow: when water pours out of the shower head and the faucet simultaneously.

This might seem harmless, but it could indicate more severe problems with your plumbing system.

Scenarios in Which This Problem Can Occur

Unexpected Shower:

It’s a chilly winter morning, and you’re trying to fill the tub for a hot, relaxing soak. But as soon as you turn the faucet on, you’re greeted with an unexpected shower. It’s not the morning surprise you were hoping for!

Prepping for Bath Time:

Picture this: you’re preparing the tub for your little one’s bath time. As the tub fills, water starts to gush from the shower head. This isn’t the water play your kiddo was expecting!

Cleaning the Tub:

You’re doing your regular bathroom cleaning, and suddenly, as you turn on the faucet to rinse off the cleaning solution, a cascade of water starts pouring from the showerhead. It’s not exactly the help you need!

Through countless encounters with these scenarios, I’ve learned that simultaneous water flow is more common than you’d think. But don’t worry!

The good news is it’s typically an easy fix. Stick with me as we journey through the world of plumbing to find out how to resolve this pesky issue.

Potential Causes

1. Faulty Diverter Valve

You might be wondering, “What’s a diverter valve?” Well, it’s truly the unsung hero of the bathroom. This tiny device in your shower directs water from the faucet to the showerhead.

You’re operating the diverter valve when you lift that lever or twist that knob on your bath faucet.

2. How It Can Malfunction

There was a time when I couldn’t get any water from my showerhead, no matter how hard I turned the lever. This is a classic example of a malfunctioning diverter valve.

Over time, this little device can wear out, get stuck, or break down. If this happens, it can cause water to flow from the faucet and showerhead concurrently, leading to simultaneous water flow.

3. Issues with Plumbing

  • Leaks or Clogs

Remember when I mentioned that the water pressure in my apartment was so low that it felt like I was bathing under a trickle?

It was a leak in my plumbing, causing reduced pressure and improper water distribution.

Similarly, clogs can disrupt water flow, leading to unforeseen issues such as simultaneous water flow.

  • Airlock Problems

Accounting for airlock problems in home plumbing is something most people never have to consider, myself included, until one day, I noticed a sudden gush of water from my showerhead when I was filling the tub.

An airlock can cause water to flow erratically or from multiple outlets.

4. Improper Installation or Design

  • Unintended Design Flaws

Sometimes, things look great on paper but don’t work as well in practice, like when I enthusiastically installed a fashionable new faucet in my guest bathroom.

Its sleek design was eye-catching, but unknown to me, its design flaw was causing water to flow from the tub and showerhead.

  • Mistakes in Installation

As a proud DIY enthusiast, I’ve had my share of mishaps. One was when I installed a new bathtub and forgot to align the diverter valve properly.

The result? You guessed it – simultaneous water flow. It was a harsh lesson learned about the importance of correct installation.

Diagnosing the Problem

Understanding the root cause of a problem is half the battle won, just as I realized when I encountered the issue of simultaneous water flow. Here’s how you can identify the root cause and some troubleshooting tips:

How to Identify the Root Cause

Like any great detective, you must gather and analyze your clues. In the case of plumbing problems, these clues come as symptoms.

For instance, if water pressure is low, there might be a leak or a clog somewhere. On the other hand, if water is flowing erratically or from multiple outlets, an airlock or a faulty diverter valve could be the culprit.

Remember when I installed a fancy new faucet, only to find later that its design flaw was causing simultaneous water flow?

That taught me just how crucial it is to examine all aspects of the issue and not jump to conclusions.

Tips for Troubleshooting

Once you’ve identified potential causes, it’s time for some hands-on troubleshooting. Start with the most straightforward possibility and work your way up.

For instance, if you suspect a clog, try clearing it using a plunger or a plumber’s snake. If that doesn’t work, you might need to consider other possibilities.

My mantra for troubleshooting is ‘be patient and persistent.’ Remember when I messed up installing a bathtub because I rushed through the process?

That mistake taught me the importance of taking my time to get things right the first time around.

And finally, don’t be afraid to call in the professionals. I’ve learned that sometimes, what seems like a minor issue can be a symptom of a much bigger problem, and it’s better to let the pros handle it than to risk causing more damage. Always remember, it’s okay to ask for help.

Solutions and Fixes

Let’s deeply dive into the various solutions and fixes for common plumbing issues. Remember, it’s all about having the right tools and the patience to tackle these problems.

1. Repairing or Replacing the Diverter Valve

One of my most memorable experiences involved a faulty diverter valve. I noticed an erratic water flow in the shower, which was getting on my nerves.

First, I removed the diverter handle and the escutcheon plate to access the valve. I carefully removed the diverter stem using a deep socket and confirmed it was faulty.

I replaced it with a new one, and my shower was normal. This repair taught me the importance of careful observation and knowing your plumbing fixtures.

2. Plumbing Solutions

I remember a time when my sink was draining painfully slowly. It initially seemed like a minor issue, but it got progressively worse.

I tried various solutions, such as hot water, vinegar, baking soda, and a plunger. But the best solution was an excellent old-fashioned plumber’s snake.

I could dislodge the clog and restore normal flow by feeding the snake down the sink. The experience reminded me that the most straightforward tools are sometimes the most effective.

3. Seeking Professional Help if Necessary

Lastly, there was a time when my DIY chops met their match: the insidious slab leak. Despite my best efforts, I couldn’t pinpoint the source of the leak. It was time to call in the professionals.

An experienced plumber used specialized detection equipment to locate and fix the leak with minimal disruption to the rest of the house.

This incident served as a reminder that while DIY can be rewarding, there’s no replacement for professional expertise when it’s genuinely needed.

So remember, don’t hesitate to call a professional when a plumbing issue is beyond your skills or comfort level.

Preventative Measures

  • Regular Maintenance

Regular maintenance is the unsung hero of a well-functioning plumbing system. I’ve found that a small monthly investment of time can save me substantial hassle and cost in the future.

I check my faucets for leaks, inspecting pipes for corrosion, and ensuring my drains are clear and running smoothly.

I also schedule a professional inspection annually to catch any issues that may have slipped past my amateur eyes. It’s like going to the dentist – regular check-ups can prevent much pain!

  • Proper Installation and Design Considerations

Experience has taught me that starting right can save a lot of wrong turns later on.

When I renovated my bathroom, I took the time to research different plumbing fixtures and layouts, considering factors like water pressure and the house’s overall plumbing design.

I consulted with a professional to ensure everything was installed correctly. This upfront investment of time and money saved me from several potential issues, and I’ve enjoyed trouble-free usage ever since.

  • Tips for Avoiding Future Issues

Looking back at the plumbing snags I’ve faced, a few key takeaways come to mind.

First, never ignore a minor issue; it could be a symptom of something more significant.

Second, understand your limits – DIY can be fun and rewarding, but don’t hesitate to call a professional when necessary.

Lastly, invest in quality fixtures and regular maintenance. After all, prevention is better (and often cheaper) than cure!

Common Misconceptions

Just as with many aspects of life, there’s plenty of misinformation floating around when it comes to plumbing. Let’s debunk a few of those common myths and misconceptions.

  • Leaky Faucets Are No Big Deal
This is one of the most common misconceptions I’ve encountered in my plumbing journey.

A leaky faucet may seem insignificant, but did you know a faucet that drips once per second can waste over 3,000 gallons of water yearly?

That’s enough water for over 180 showers! I once ignored a slightly leaky faucet in my guest bathroom, thinking it was no big deal. Two months later, I was shocked when I got my water bill.

  • All Plumbers Are the Same
Just because someone claims to be a plumber doesn’t mean they have the necessary qualifications or experience.

I learned this the hard way when I hired a random person advertising their plumbing services online.

Not only did they incorrectly install a new toilet, but they also left quite a mess. Since then, I have always hired a licensed plumber with good references.

  • Chemical Drain Cleaners Are the Best Solution for Clogs
It’s easy to reach for that bottle of chemical drain cleaner when you have a clogged drain, but I can tell you it’s not always the best idea.

Once a plumber explained that these chemicals can cause severe damage to pipes over time, I switched to using a plumbing snake and homemade drain cleaning solutions.

My pipes are clear now, and I’m not contributing to unnecessary chemical pollution.

  • Flushable Wipes Are Okay to Flush
Despite what the packaging might say, “flushable” wipes are a plumber’s nightmare. They don’t break down like toilet paper and can cause serious clogs.

One Christmas Eve, I spent hours battling a severe clog caused by a guest flushing these wipes down the toilet. Let’s say it wasn’t the holiday memory I hoped to create!


In summary, it’s critically important to remember the following points. Firstly, even a minor leak in your faucet can lead to significant water wastage, so it’s always a good idea to fix it immediately.

Secondly, not all plumbers are created equal; always hire a licensed professional with good references.

Thirdly, chemical drain cleaners can do more harm than good in the long run despite being convenient.

Lastly, never flush “flushable” wipes, or you’ll risk a nasty clog – believe me, I’ve learned this one from a miserably spent Christmas Eve.
