In this article, we will provide clear and easy-to-follow steps for increasing the water pressure in your shower. Whether you use a rain shower head or regular, say goodbye to low pressure and disappointing showers and hello to an invigorating and refreshing experience!

Why is your shower water pressure low?

1 – Clogged nozzles or pipes

One of the common culprits of low water pressure in the shower is a clogged shower head or pipes from mineral deposits. When the nozzles of the shower head become clogged with mineral deposits or debris, it can restrict the water pressure and result in a weak and unsatisfying stream.

To fix this low pressure problem, you may need to disassemble the shower head and clean the nozzles. In some cases, simply soaking the shower head in a mixture of vinegar and water can help to loosen and remove any mineral deposits or debris.

2 – Incorrect installation of shower head or pipes

Incorrect installation of the shower head or pipes can also lead to low pressure. If the shower head is not installed properly, it may not be able to generate enough water pressure to create a strong and satisfying stream of water.

3 – Low household water pressure

If the low water pressure in your shower is not isolated to just the shower head but instead affects the entire house, it could be due to a problem with the water supply line or the pressure valve.

The water supply line is responsible for bringing water into your home, and if it becomes clogged or damaged, it can reduce the overall water pressure. Similarly, the pressure valve is responsible for regulating the water pressure and if it becomes faulty, it can cause low pressure throughout the house.

6 ways to increase shower water pressure 

We’ve figured out a few solutions to the common reasons why there is low pressure in the shower. In this section, we’ll start with the most common solutions and go down the line so you can find the one that will help increase the water pressure.

1 – Install a high-pressure shower head

If you feel that the water-pressure problem is coming directly from the shower head then replacing it with a high-pressure one will probably do the trick. Installing a high-pressure shower head can be a quick and easy way to increase the low pressure of your shower and give you a more invigorating shower experience.

Here’s how to do it:

  1. First, gather the necessary tools and materials. You will need a screwdriver, adjustable wrench, plumber’s tape, and the new shower head.
  2. Turn off the water supply to the shower. This can usually be done by closing the valves behind the shower wall or under the sink.
  3. Remove the old shower head by holding onto the base and turning it counterclockwise with the adjustable wrench. If the shower head is difficult to remove, you may need to apply penetrating oil to the connection.
  4. Wrap a few layers of plumber’s tape around the threads of the shower arm to create a watertight seal.
  5. Hold the new shower head up to the shower arm and align the threads.
  6. Attach the new shower head by turning it clockwise with the adjustable wrench. Be sure not to overtighten, as this can strip the threads or damage the shower head.
  7. Turn the water supply back on and test the new shower head to make sure it is properly installed and functioning correctly.

2 – Cleaning or replacing clogged nozzles

When you have hard water in your home then mineral deposits can build up in the shower head and create low pressure. If you haven’t been regularly keeping up with descaling it then you should do so to see if it is the cause of the water pressure problem. 

How to clean clogged shower head nozzles:

Total Time: 2 hours

Prepare the solution

First, fill the bowl or container with equal parts white vinegar and water.

Detach shower head

Remove the shower head from the wall by either unscrewing it or using a wrench to loosen it.

Soak it

Place the shower head in the bowl or container of vinegar and water solution, making sure that the nozzles are fully submerged.

Let it sit

Let the shower head soak in the solution for at least an hour. This will help to loosen any dirt or debris that may be clogging the nozzles.

Scrub it

After an hour, use a toothbrush or small brush to gently scrub the nozzles to remove any remaining dirt or debris.

Rinse it

Rinse the shower head thoroughly with water to remove any remaining vinegar solution.

Test it

Reattach the shower head to the wall and turn on the water to test the flow. If the shower head is still clogged, you may need to repeat the process or try using a mixture of baking soda and water instead of vinegar.

If the nozzles are beyond cleaning and are severely clogged or damaged, you may need to replace them. To do this:

  • Follow the steps above to remove the shower head from the wall.
  • Look for a small set screw or clip that holds the nozzles in place. You may need to use a small screwdriver or pliers to loosen this.
  • Once the set screw or clip is removed, you should be able to gently pull the nozzles out.
  • Replace the old nozzles with new ones, making sure they are properly secured in place.
  • Reattach the shower head to the wall and turn on the water to test the flow.

It’s a good idea to regularly clean your shower head nozzles to ensure that they are functioning properly and providing strong water pressure.

3 – Adjust the flow restrictor or water pressure regulator

The flow restrictor or water pressure regulator in a shower head is designed to control the amount of water that flows through the head, which can help to conserve water and reduce your water bill. However, sometimes the flow restrictor may need to be adjusted to increase or decrease the water pressure.

Here’s how to do it:

  • First, locate the flow restrictor. It is usually found inside the shower head itself, either in the connection to the arm or near the nozzles.
  • Remove the shower head from the wall by either unscrewing it or using a wrench to loosen it.
  • Look for a small set screw or clip that holds the flow restrictor in place. You may need to use a small screwdriver or pliers to loosen this.
  • Once the set screw or clip is removed, you should be able to gently pull the flow restrictor out.
  • Adjust the flow restrictor as needed by turning it clockwise to increase the water flow or counterclockwise to decrease it.
  • Replace the flow restrictor and secure it in place with the set screw or clip.
  • Reattach the shower head to the wall and turn on the water to test the flow. If the water pressure is still not to your liking, you may need to adjust the flow restrictor further.

It’s important to note that adjusting the flow restrictor too much can cause damage to the shower head or the plumbing system, so be sure to make only small adjustments at a time.

4 – Replace the shower hose

A faulty shower hose can be a nuisance, as it can cause low pressure. Sometimes the hose gets bent and restricts the water pressure. Others get leaks that affect the water pressure. If your shower hose is damaged or not functioning properly, it may be time to replace it.

Here’s how to do it:

  • You will need a screwdriver, adjustable wrench, plumber’s tape, and the new shower hose.
  • Turn off the water supply to the shower. This can usually be done by closing the valves behind the shower wall or under the sink.
  • Use the screwdriver to loosen the mounting hardware that holds the shower hose in place.
  • Once the mounting hardware is removed, gently pull the shower hose out from the shower head and the wall connection.
  • Inspect the end of the shower hose for any damage or debris that may be blocking the flow of water.
  • If the end of the hose is damaged or clogged, it may need to be replaced as well.
  • Wrap a few layers of plumber’s tape around the threads of the shower head and wall connection to create a watertight seal.
  • Attach the new shower hose to the shower head and the wall connection by turning it clockwise with the adjustable wrench. Be sure not to overtighten, as this can strip the threads or damage the hose.
  • Turn the water supply back on and test the new shower hose to make sure it is properly installed and functioning correctly.

5 – Increasing the water pressure for the entire house

If you’re having issues with low water pressure throughout your entire house, there are a few steps you can take to try and increase water pressure.

Here are some options to consider to increase household water pressure:

  • Check for leaks: Low water pressure can sometimes be caused by leaks in the plumbing system. Inspect your pipes and fixtures for any visible signs of leakage, such as dripping faucets or wet spots on the walls or floor.
  • Check the water pressure regulator: The water pressure regulator’s job is to control the flow of water into your home. If it’s not functioning properly, it can cause low water pressure. You can check the pressure regulator by locating the main water pressure reducing valve and attaching a water pressure gauge to it. If the pressure is too low, you may need to adjust the regulator or have it replaced.
  • Install a water pressure booster: If the above steps don’t help improve the water pressure, you may want to consider installing a water pressure booster. These devices are installed on the main water line and use a pump to increase the water pressure throughout the house.

6 – Don’t run other water-using appliances

Running other water-using appliances, such as the washing machine or dishwasher, while taking a shower can significantly decrease the water pressure in the shower. This is because these appliances are also drawing water from the same supply line, which can reduce the amount of water available for the shower. To avoid this issue and maintain a strong water pressure in the shower, it’s best to avoid running other water-using appliances at the same time.

Additionally, showering at non-peak times, such as early in the morning or late at night, can help to improve the water pressure.

Final thoughts

By fixing your water pressure you can bring your shower back from being a chore to being one of your favorite things to do at home. Most people are looking for a spa like experience in the shower and having good water pressure is essential. Use the tips above and you will achieve this.
