How to Lower Shower Water Pressure and Improve Your Home's Water Pressure

Symptoms of High Pressure

Symptoms of high shower water pressure include audible disturbances, seepage, or excessive water consumption. Checking not only the shower but also other fixtures like the sink faucet is crucial when suspecting high shower water pressure as it helps to identify the root cause of the issue.

Removing a flow restrictor, a device that limits water flow, from your showerhead can result in an increase in water pressure.

Measuring Water Pressure

To determine if your shower water pressure is too high, you can use a water pressure gauge. These devices can be purchased from a home store for approximately $10 and are capable of reading pressure in both PSI and Bars.

To check the water pressure, follow these steps:

  1. Attach the gauge to a male threaded faucet, such as a laundry tub, hose bib, or water heater drain connection.
  2. Turn on the water to use the gauge.
  3. If the water pressure gauge indicates a reading of over 80 PSI, it is recommended to lower the pressure.

How to Increase Water Pressure in Shower

If you're dealing with lackluster water pressure during your showers, understanding how to increase water pressure in the shower is crucial for a more invigorating and satisfying bathing experience. There are several effective methods and simple adjustments you can implement to enhance the water pressure in your shower, ensuring a more enjoyable and refreshing bathing routine.

Adjusting the Water Pressure Regulator

If a faulty water pressure regulator is suspected, adjusting it may help control shower water pressure and achieve the desired levels. Water pressure regulators are vital in this process. The process involves loosening the locking nut with a wrench and turning the adjustment screw in quarter-turn increments to increase or decrease water pressure.

Before working with a water pressure regulator, consider the main water valve and the condition of the incoming water-service support for the water distribution piping in the location where you plan to work.

Locating the Regulator

The water pressure regulator is typically installed near the main shut-off valve for the water supply, directly after the water enters the home.

When assessing the pressure regulator, look for any indications of corrosion, leaks, or other damage.

Making Adjustments

To adjust the water pressure regulator, rotate the knob or lever in a clockwise direction to increase the pressure, or counterclockwise to decrease the pressure.

If the water pressure remains too high after making adjustments, it’s recommended to repeat the process until the desired pressure is achieved. Exercise caution when turning the valves, as excessive force may result in the entire shower tap being shut off.

Cleaning or Replacing the Showerhead

Optimal water pressure can be ensured by cleaning or replacing the showerhead. Reduced shower water pressure often results from mineral buildup in the pipes caused by hard water.

Additionally, mineral deposits can accumulate in the showerhead, further decreasing water pressure.

How to Fix Low Water Pressure in Shower

If you're wondering how to fix low water pressure in your shower, there are several steps you can take to address and improve the situation. Start by checking the showerhead for any mineral deposits or debris that might be clogging the openings. A simple cleaning or soaking in vinegar can often remedy this. Next, examine the water shut-off valves to ensure they are fully open, allowing maximum water flow to the shower. Sometimes, outdated or faulty piping can also be a culprit; consider consulting a plumber to evaluate and potentially replace any corroded or inadequate pipes. Additionally, investing in a high-efficiency showerhead designed to optimize water usage can significantly enhance the pressure while conserving water. Finally, if these steps don't provide the desired improvement, consulting a professional plumber for a thorough assessment and appropriate fixes is advisable.

Removing Mineral Deposits

One effective way to clean mineral deposits from the showerhead is by soaking it in a bowl of white vinegar overnight or wrapping a plastic bag with white vinegar solution around the head of the shower.

Alternatively, you can scrub the showerhead with an old toothbrush and vinegar to loosen debris. If the vinegar solution fails to remove the buildup, it’s recommended to contact a plumber, as a replacement showerhead may be necessary.

Choosing a Low-Flow Showerhead

Low-flow shower heads offer the advantage of sustaining steady water pressure. These devices have a flow rate lower than 1.5 gallons per minute (gpm) and are designed to reduce water consumption and decrease water bills.

When selecting a low-flow showerhead, consider a flow rate of less than 1.5 gpm, adjustable spray settings, anti-clog nozzles, and self-cleaning technology.

Balancing Hot and Cold Water PressureBalancing Hot and Cold Water Pressure



To ensure even shower water pressure, it’s important to balance hot and cold water pressure. This can be achieved using a balancing pressure shower valve, a device that maintains a consistent flow of both hot and cold water.

By addressing any issues with mixing valves, you can achieve a more consistent and enjoyable shower experience.

Checking Mixing Valves

To inspect and adjust mixing valves for proper hot and cold water balance, first isolate the cold water supply to the mixing valve by turning off the cold water supply valve. After waiting at least five seconds, measure the mixed water temperature with a thermometer.

Ensure that the hot water temperature is within the desired range.

Troubleshooting Temperature Fluctuations

Temperature fluctuations that may affect shower water pressure can be caused by a malfunctioning mixing valve, clogged pipes, or a malfunctioning water heater.

If any issues are encountered with the mixing valve, it should be replaced. To replace the mixing valve, turn off the water supply, disconnect the old valve, and install the new valve.

Inspecting Your Plumbing System
