Experiencing high water pressure in your shower can be more than just an uncomfortable showering experience; it can also signify potential problems in your plumbing system. While a strong shower stream might seem desirable, excessively high water pressure can lead to damaged pipes, leaks, and increased wear and tear on your plumbing fixtures. We are going to look at ways to decrease the water pressure in your shower because understanding and fixing this issue is crucial not only for your comfort but also for the health and longevity of your home’s plumbing system.

Powerful Showerhead

Method 1: Inspect O-Ring and Clean the Shower Head with Vinegar

If your shower suddenly exhibits high water pressure, addressing it might be as simple as inspecting and cleaning the shower head. Here’s a streamlined approach:

Disassemble the Shower Head

Begin by carefully removing the shower head from its fixture. This usually involves unscrewing it either by hand or with the help of adjustable pliers. Be gentle to avoid damaging the fixture. Once removed, place the shower head on a clean surface. This will expose the internal components, such as the O-ring, filter screen, and any washers.

Check and Adjust the O-Ring

Inside the shower head, locate the O-ring, a small rubber ring that helps seal and control water flow. Examine it closely for any signs of wear, cracks, or damage. If the O-ring appears damaged or worn out, replace it with a new one of the same size and thickness. If it’s in good condition but the shower pressure is still high, try adjusting its position slightly to alter the water flow.

Soak in Vinegar

To remove mineral deposits from the shower head, create a solution of equal parts white vinegar and water in a bowl. Submerge the disassembled shower head parts, including the O-ring and any other removable components, in this solution. Let them soak for several hours, ideally overnight. This will help dissolve the mineral buildup that could be affecting the water pressure.

After soaking, rinse each part thoroughly with water to remove any lingering vinegar solution, and then reassemble the shower head and attach it back to the fixture.

Method 2: Check and Adjust Valves

Adjusting the flow valves located near the shower unit can reduce the pressure and make your shower experience more comfortable:

Locate the Valves

Start by finding the shower valves, which are generally located either near the shower unit, under the bath or in a central plumbing area, such as a utility room or basement. These valves control the water flow to your shower and are integral to adjusting the pressure.

Inspect the Valves

Inspect each valve for signs of wear, damage, or corrosion. Also, check if they are too tight or too loose. Both conditions can impact the water pressure in your shower, potentially leading to issues.

Adjust the Valves

To adjust the valves, turn them carefully, typically clockwise, to reduce water flow and pressure. Do this incrementally and test the shower after each adjustment. Continue this process until you reach an optimal pressure level. It’s important to adjust slowly to avoid reducing the pressure too much, which can lead to an unsatisfactory shower experience.

Method 3: Buy a New Showerhead

This may not be ideal but buying a new showerhead that reduces the flow of water as a feature may be the way to go:

Selecting the Right Showerhead

When shopping for a new showerhead to address high water pressure issues, focus on models specifically engineered for this purpose. Look for showerheads with built-in flow restrictors or those labelled as low-flow. These types are designed to reduce water output, thereby lowering pressure. Additionally, consider features like the spray pattern, ease of installation, and any water-saving features, which can enhance your showering experience while conserving water.


Installing your new showerhead is typically straightforward. Carefully follow the manufacturer’s instructions. Ensure that the showerhead is securely fitted to avoid any leaks and to maintain effective pressure control. You might need tools like a wrench and Teflon tape to secure the connection.


Upgrading to a new showerhead can offer numerous benefits. These include improved water efficiency, which can lead to lower utility bills, and a more balanced and comfortable showering experience. Additionally, by reducing water usage, you’re contributing to environmental conservation.

Method 4: Install a Pressure Reducing Valve for the Entire Property

If the water pressure for your whole house is too high or is inconsistent, you may want to install a pressure reducing valve:

Understanding Pressure-Reducing Valves

A pressure-reducing valve is a crucial component in managing the water pressure for your entire property. It works by automatically adjusting the incoming water pressure from the main line to a level that is safe and consistent for your home’s plumbing. This valve plays a vital role in maintaining steady water pressure, preventing the potential for damage due to high pressure, such as pipe bursts or leaky fixtures.


Installing a pressure-reducing valve typically involves identifying the main water line and integrating the valve into the system. The process involves shutting off the main water supply, cutting into the pipe, and fitting the valve. This can be done yourself but if you are not confident cutting into your plumbing, it is best left to a professional.

Impact on Water Pressure

Installing a pressure-reducing valve can significantly balance the water pressure throughout your home. It ensures that the pressure is at a safe and comfortable level, reducing the risk of damage to your plumbing system and improving the overall functionality of water fixtures, leading to a more reliable and efficient water supply.


In this guide, we explored four effective methods to manage and decrease the water pressure in your shower: cleaning and adjusting the shower head, checking and adjusting the valves, buying a new showerhead, and installing a pressure-reducing valve for your entire property. Each method addresses different aspects of the issue and provides a range of solutions from quick fixes to more comprehensive approaches. Properly diagnosing and addressing high water pressure is crucial for the efficiency and longevity of your home’s plumbing system. Regular maintenance and timely interventions can prevent potential damage and ensure a comfortable and sustainable water usage experience.
