Removing the pressure control from a bonsai pulse shower often involves accessing the showerhead itself. You may need to unscrew the showerhead to find internal components that regulate water pressure or pulsing action. The goal is to gently remove or bypass these parts.
Always turn off the water supply first. Check your shower’s manual if you have it. Safety and caution are key when working with plumbing.
Understanding Your Bonsai Pulse Shower
A bonsai pulse shower is designed to give a unique shower experience. It uses different water spray patterns. Some models have a special pressure control.
This helps manage how strong the water feels. It can also affect the pulsing action. The idea is to offer a massage-like feel.
Or it might be for water saving. But sometimes, this control isn’t what you want. You might want a stronger spray.
Or maybe the pulsing is annoying. Understanding what this part does is the first step. It helps you know why you might want to change it.
Think about your showerhead. It has tiny holes where water comes out. These are called nozzles.
The pressure control is usually a small part inside. It sits between the water pipe and the nozzles. It can limit how much water flows through.
Or it can change the water flow rhythm. This change affects the spray. It can make it softer or harder.
It can also make it pulse. Some people love this feature. Others find it too weak.
Or they just want a simple, strong shower. That’s where figuring out how to remove it comes in.
Your shower connects to your home’s water pipes. Water travels from your water heater to your shower. The showerhead is the last stop.
Inside, there’s often a mechanism. This is the pressure control. It might be a small disc with holes.
Or it could be a spring-loaded valve. It’s often made of plastic or rubber. Its job is to restrict or alter the water flow.
This is controlled by the settings on your showerhead. You might have buttons or a dial for this. If you can’t adjust it enough, you might consider removing it.
The “pulse” in bonsai pulse shower often comes from this control. It might rapidly open and close. This makes the water feel like it’s tapping you.
It’s meant to be invigorating. But if you prefer a steady stream, this pulse can be a problem. The pressure control is directly linked to this pulsing.
If you remove the control, you’ll likely stop the pulsing. You’ll also change the water pressure. This is why knowing what you’re doing is important.
It’s not just about stopping the pulse. It’s about changing the whole shower feel.
Many modern showerheads have these features built-in. They try to offer variety. But what one person finds perfect, another might not.
The pressure control is a key part of this. It’s a way to offer multiple experiences from one showerhead. But if you only want one specific experience, it can be a barrier.
You might even find the control is faulty. It might stick or not work correctly. In these cases, removal is a good solution.
It lets you get back to a basic, strong shower. Or it lets you set up the shower exactly how you want it.

My Own Shower Head Scare
I remember a few years ago. I bought this fancy new showerhead. It promised all sorts of settings.
It had this “pulsating massage” option. I thought, “Great! A spa in my own bathroom!” I installed it.
The water turned on. It was. weird.
It felt like tiny, weak hammers hitting me. Not relaxing at all. I fiddled with the settings.
I turned the dial. I pressed buttons. Nothing made it feel like a normal shower.
It was just weak and buzzy. I started to get really annoyed. It was like the shower was mocking me.
I felt so defeated. I had spent good money on this thing. And it was worse than my old, basic showerhead.
I stood there, dripping and frustrated. My partner came in. They asked, “What’s wrong?” I just pointed at the showerhead.
“It pulses!” I practically shouted. They laughed a little. Then they said, “Can’t you just turn that off?” I explained I had tried everything.
They looked at it. “Maybe it’s broken?” they suggested. Or maybe, I thought, I just don’t want it to pulse.
That’s when I started looking online. I wanted to know if I could change how it worked. Could I make it stop pulsing?
Could I get more pressure? I found forums. I read articles.
I learned about pressure restrictors. And about these “pulse” features. Most people just accepted them.
But some people wanted them gone. They wanted a simple, strong shower. The idea of taking it apart started to form.
It sounded scary. Plumbing and all that. But my shower was that bad.
I had to try something. I took a deep breath. I decided I would try to remove the pressure control.
What Is a Pressure Restrictor Anyway?
So, what exactly is this pressure control? In many showers, especially those sold in the U.S., there’s a part called a pressure restrictor. The government put these in.
They wanted to save water. They also wanted to save energy. Less hot water used means less energy to heat it.
This part usually sits right where the water pipe meets the showerhead. It’s often a small plastic piece. It might look like a little washer.
It has a small hole in the middle.
This small hole is the key. It limits how much water can flow through. Even if your home has high water pressure, this restrictor caps it.
It ensures your shower doesn’t use more than a certain amount of water per minute. For a standard showerhead, this is often 2.5 gallons per minute (GPM). Some newer ones are even lower, like 1.8 GPM.
This is what saves water. It also helps conserve energy. You use less hot water, so your water heater works less.
But for some people, this is a problem. They might have good water pressure already. Or they might live in a place with lower natural pressure.
The restrictor makes it feel weaker. It can also affect showerhead performance. Some fancy spray patterns need more pressure to work well.
The pulsing effect is often created by a specific type of restrictor. It might be designed to rapidly change the water flow. This creates the “massage” or “pulse” feeling.
Sometimes, a pressure restrictor can get clogged. Mineral deposits from hard water can build up. This can make the water flow even more restricted.
Or it can cause it to spray unevenly. If you have hard water, this is common. Cleaning the showerhead might help.
But if the restrictor is just too small for your liking, it’s a different story. Removing it means you’ll get the full water pressure your home can provide. For many, this makes a big difference.
The shower feels much stronger. The spray is more powerful. And the annoying pulse might disappear.
It’s important to note that in some areas, removing these restrictors might be against local water-saving codes. However, for most homeowners, it’s a simple modification to improve shower performance. The goal isn’t to waste water wildly.
It’s to get a shower that feels good to you. And for many, a strong, steady stream is the ideal. The pressure restrictor is often the only thing standing in the way of that.
Understanding its purpose is crucial before you decide to remove it.
Why You Might Remove It
Common Reasons to Remove:
- Weak Water Pressure: Your shower feels too soft.
- Dislike Pulsing: The massage or pulse action is unwanted.
- Improve Spray Pattern: Some settings work better with more pressure.
- Clogged Restrictor: Deposits made it perform poorly.
- Personal Preference: You just want a strong, steady shower.
Taking Apart Your Showerhead Safely
Before you start, gather your tools. You’ll need a few simple things. A wrench is usually needed.
An adjustable wrench works best. You might also want some plumber’s tape. This helps create a watertight seal.
And a soft cloth or towel is a good idea. You don’t want to scratch your showerhead. Most importantly, you need to turn off the water supply.
Find the shut-off valve for your shower. If you can’t find one for just the shower, you might need to shut off the main water to your house. This is very important.
Once the water is off, you can begin. Hold the showerhead firmly. Use your wrench to loosen the connection.
It’s usually where the shower arm meets the showerhead. Turn the wrench counter-clockwise. Do this gently.
You don’t want to force it. If it’s stuck, try a little more pressure. The soft cloth can protect the finish.
Once it’s loose, you should be able to unscrew it by hand. Be prepared for a little residual water to drip out. That’s why the towel is useful.
With the showerhead in your hand, look inside. You should see the part where the water enters. Sometimes the restrictor is obvious.
It might be a small plastic disc. It could have a tiny hole. You might need to pry it out gently.
A small screwdriver or a utility knife can help. Be careful not to damage the showerhead housing. If you can’t see it right away, check your showerhead’s manual.
It will show you the internal parts. It might be hidden behind a screen or a larger piece.
Some showerheads have a more complex system. They might have a rubber washer that includes the restrictor. In this case, you might need to replace the entire washer.
Or you might be able to carefully cut out the restrictor part of the washer. If it’s a metal screen, you might need to remove that too. The goal is to create a clear path for water.
For the pulsing effect, there might be a specific valve or mechanism. You’ll need to identify that part. It’s often a small spring-loaded piece.
You can usually just pull it out. It might require a bit of wiggling.
Once you’ve removed the part you believe is the pressure control or restrictor, take a good look. Does it look like it was limiting flow? Does it seem related to the pulsing?
If you’re unsure, it’s okay to consult online videos. Search for your specific showerhead model. Many people document these kinds of changes.
Seeing someone else do it can be very helpful. It reduces the guesswork. And it makes the process feel less daunting.
Remember, patience is key. Don’t rush. Rushing can lead to mistakes.
Tools You Might Need:
- Adjustable Wrench
- Plumber’s Tape
- Soft Cloth or Towel
- Small Flathead Screwdriver or Utility Knife (for prying)
- Showerhead Manual (if available)
Identifying the Specific Part
Now, let’s get a bit more specific about what you’re looking for. On a bonsai pulse shower, the “pressure control” isn’t always a single, simple restrictor disc. It can be part of a more complex mechanism that creates the pulsing.
Often, you’ll find a small rubber washer with a hole. This is your basic restrictor. If you remove this, you’ll increase the flow.
But it might not stop the pulsing. The pulsing is usually caused by something else inside.
Look for a part that seems to move or change shape. It might be a small plastic piece that sits on a spring. When water hits it, it might push back.
This movement can create the pulse. It’s like a tiny hammer inside your showerhead. This piece is designed to interrupt the steady flow of water.
It makes the water come out in short bursts. If you want to stop the pulsing, this is the part you need to remove. It might be held in place by a small clip or just friction.
Sometimes, manufacturers use a flow-limiting screen. This is a mesh-like material. It’s designed to reduce flow and potentially create a finer spray.
This isn’t usually what causes the pulsing. But it does affect pressure. You might find this screen near the inlet of the showerhead.
If you’re aiming for maximum pressure and a steady stream, you might consider removing this too. However, some screens are designed to prevent debris from entering the showerhead. So, use your judgment here.
The actual “pulse” mechanism can vary greatly between brands. Some are very simple. Others are more engineered.
If you have a specific model, searching for images of its internal parts is a great idea. Look for diagrams. Look for exploded views.
These will show you exactly what each piece is. You can then identify the part responsible for the pulsing. It might be labeled as a “flow regulator” or “pulse generator.” Don’t be afraid to search for your model number plus “disassembly” or “internal parts.”
In some cases, the pulsing might be achieved through a cleverly designed nozzle plate. Instead of a separate component, the shape and angle of the holes in the spray plate itself could create the effect. If this is the case, removing a restrictor might increase pressure but won’t change the pulse.
You would then need to look into replacing the entire spray plate if that’s an option for your model. But typically, the pulsing is a separate mechanism. Identifying it is key to achieving a steady shower.
Contrast: Pulse vs. Pressure
Normal Shower: Steady water flow, consistent pressure. Feels smooth.
Bonsai Pulse Shower (Default): Water flows in rapid bursts. Feels like taps. Pressure might be lower.
After Removing Pulse Mechanism: Steady water flow. Pressure might increase. No more pulsing feel.
After Removing Pressure Restrictor (only): Water flow increases significantly. Pulse might still be present or even stronger with more flow. Pressure definitely higher.
Reassembly and Testing
Once you’ve successfully identified and removed the offending part(s), it’s time to put it all back together. This is almost as important as taking it apart. A loose connection can cause leaks.
A poorly reassembled part can malfunction. Take the showerhead. Look at where you removed the pieces.
If you removed a restrictor disc, simply leave it out. If you removed a spring-loaded pulse mechanism, just don’t put it back in. Make sure any O-rings or rubber seals are in place correctly.
Before you screw the showerhead back onto the shower arm, apply some plumber’s tape. Wrap it around the threads of the shower arm. Go clockwise.
About three to five wraps is usually enough. This tape creates a tight seal. It prevents water from leaking out at the connection.
Now, carefully screw the showerhead back onto the arm. Hand-tighten it first. Then, use your wrench to snug it up.
Don’t overtighten it. Just make it firm. Again, the cloth can protect the finish.
Now for the moment of truth. Go back to your water shut-off valve. Slowly turn the water back on.
Start with just a trickle. Listen for any immediate leaks. If everything sounds okay, open the valve fully.
Let the water run. Check the connection point between the shower arm and the showerhead. Is there any dripping?
If you see a leak, turn the water off again. You may need to tighten the connection slightly more. Or you might need to reapply the plumber’s tape.
Sometimes, the seal just isn’t perfect the first time.
Once you’re sure there are no leaks, test the shower. Turn on the water and let it run for a minute. Feel the spray.
Is it steady? Is the pressure better? Does the pulsing feel gone?
For most people, the difference is immediate and noticeable. The water should feel strong and consistent. The annoying, weak pulse should be replaced by a smooth, powerful stream.
If, for some reason, it’s still pulsing, you might have missed a component. Or the pulsing mechanism might be more integrated than you thought. In that case, you might need to revisit the disassembly step.
It’s also worth noting that some showerheads have multiple settings. Make sure you’ve tried all the different spray patterns after your modification. Sometimes, removing one part can affect how other settings work.
But typically, the goal is a strong, steady shower. And for most bonsai pulse showers, removing the pressure control and the pulse mechanism achieves this. Enjoy your improved shower experience!
Quick Check After Reassembly:
- Water Supply: Turned back on slowly?
- Connection: Showerhead to arm tight and secure?
- Leaks: Any drips at the connection point?
- Spray: Water flow steady? Pulsing gone? Pressure improved?
When to Call a Professional
While removing the pressure control from a showerhead is often a straightforward DIY task, there are times when it’s best to call in a professional. If you’re not comfortable working with plumbing at all, it’s okay to admit that. You don’t want to cause more problems than you solve.
If you turn off the water supply and still can’t get the showerhead to budge, don’t force it. You could damage the pipes or the shower valve itself. This can lead to much more expensive repairs.
Another situation where you might need help is if you’ve disassembled the showerhead and can’t figure out which part is causing the problem. Or if, after reassembly, the problem persists. Some showerheads have very specific internal designs.
They might be proprietary. Without a manual or clear diagrams, it can be hard to know what you’re doing. A plumber has experience with many different brands and models.
They can often identify the issue quickly.
If you encounter any unexpected issues, like a cracked showerhead housing or a problem with the shower valve behind the wall, it’s time to call a pro. These aren’t simple fixes. Trying to patch them up yourself could lead to water damage.
A plumber can diagnose and fix these deeper problems. They have the right tools and knowledge. They can also ensure the job is done to code.
Don’t forget about water-saving regulations. In some areas, removing a pressure restrictor might be against local codes. A professional plumber will be aware of these regulations.
They can advise you on what’s permissible in your area. They can also ensure that any modifications are done correctly and safely. If you’re in doubt at any step, it’s always better to err on the side of caution.
A professional plumber can save you time, stress, and potential costly mistakes.
Alternatives to Removal
Perhaps you don’t want to remove the pressure control or pulsing mechanism entirely. Maybe you just want a bit more pressure or less pulsing. There are alternatives to full removal.
Some showerheads come with different flow-setting inserts. You might be able to swap out a low-flow insert for a slightly higher one. This would increase pressure without removing the control completely.
Check your showerhead’s manual for options like this.
Another option is to buy a new showerhead. If your current one is too old or too difficult to modify, consider upgrading. There are many showerheads on the market that offer strong pressure.
Many also have adjustable settings. You can choose one that has a steady stream option and good pressure. You can read reviews to find models known for strong performance.
This might be an easier solution than trying to modify your current showerhead.
For the pulsing effect, some showerheads have a simple dial or lever. This lets you turn the pulse on and off. If your showerhead has this feature, you might just need to find it.
It could be a small switch on the showerhead itself. Or it might be part of the main handle. Sometimes, the pulse is designed to be a feature you can control.
You don’t always have to remove it. Just using the controls correctly might solve your problem.
If you have hard water, cleaning your showerhead regularly can help. Mineral buildup can clog the nozzles. This reduces water flow and pressure.
You can soak the showerhead in vinegar. This helps break down mineral deposits. Sometimes, just cleaning the nozzles with a pin or a brush can make a difference.
A cleaner showerhead can improve performance. It might give you a better spray even with the pressure control in place. Always check for these simpler solutions first.

Frequently Asked Questions
Will removing the pressure control void my showerhead warranty?
Yes, in most cases, modifying your showerhead by removing internal parts like the pressure restrictor or pulse mechanism will likely void the manufacturer’s warranty. If your showerhead is still under warranty, it’s worth checking the warranty terms. If you decide to proceed, you do so at your own risk regarding future warranty claims.
How can I tell if my showerhead has a pressure restrictor or a pulse mechanism?
You can usually tell by the shower’s behavior. If the water pressure feels consistently weak, even when your home’s water pressure is good, you likely have a pressure restrictor. If the water comes out in rapid, choppy bursts that feel like taps, you have a pulse mechanism.
Disassembling the showerhead as described in this guide is the best way to visually confirm its internal parts.
Can I remove the pressure restrictor but keep the pulsing function?
Generally, no. The pressure restrictor and the pulse mechanism are often integrated or work closely together. Removing the restrictor increases the overall water flow.
This increased flow might even make the pulsing more intense, or it could interfere with the delicate balance needed for the pulse to function as intended. The goal of removing the restrictor is usually to get more flow, which can be incompatible with the precise control needed for pulsing.
What if my showerhead has multiple spray settings? Will removing the restrictor affect them?
Yes, it can. Removing a pressure restrictor will increase the water flow to all settings. This might make some settings feel much stronger than intended.
It could also change the spray pattern slightly. If your showerhead has a “massage” or “pulse” setting, that particular setting might become more intense or less defined. The goal of removal is typically to achieve a stronger, steadier spray across all modes, or to have one main strong mode.
Is it legal to remove the pressure restrictor from my showerhead?
In the United States, federal regulations limit showerhead flow rates to 2.5 gallons per minute (GPM). Many new showerheads are designed to meet even lower standards (e.g., 1.8 GPM) for water and energy conservation. While the government mandates these limits, enforcement typically focuses on manufacturers and retailers.
Homeowners removing restrictors for personal use generally face no direct legal penalty, though some local ordinances might exist. It’s primarily a matter of personal choice for improving shower performance.
How much pressure should I expect after removing the restrictor?
You should expect the pressure to match your home’s natural water pressure. If your home has good water pressure, your shower will feel significantly stronger. If your home’s water pressure is naturally low, removing the restrictor will help, but it won’t magically create pressure that isn’t there.
The goal is to get the maximum pressure your plumbing system can deliver to the showerhead.
Final Thoughts
Changing your shower experience can make a big difference. You want your shower to feel good. If your bonsai pulse shower isn’t quite right, you have options.
Removing the pressure control is a common fix. It can give you the strong, steady shower you’re looking for. Just remember to be careful.
Turn off the water. Use the right tools. And take your time.
Most of the time, it’s a simple fix. You can enjoy a better shower very soon. It’s about making your home work for you.
And your shower is an important part of that. Enjoy that improved stream!
