A slow water pressure from a shower is quite frustrating during a shower. However, the slow flow rate from a shower is much more than what you think. According to research and findings, an average American shower lasts 8 minutes and uses around 17 gallons (65 liters) of water. This is a lot of water, ranking after toilet and washing machines.
Water conservation policies have limited the maximum flow rate a shower can have. Most showers manufactured after 1992 come with a flow restrictor that controls the water flow according to the federal policies.
The federal standard in the United States for shower flow rate is set at a maximum of 2.5 gallons per minute (GPM), a mandate established under the Energy Policy Act of 1992. However, various states have implemented their own, more stringent standards. For example, California, Hawaii, New York, and Oregon have set the maximum flow rate for showerheads at 1.8 GPM. Other states like Colorado, Massachusetts, New Jersey, Rhode Island, and Vermont have a limit of 2.0 GPM. Maine and Maryland are currently at 2.5 GPM, but Maryland plans to move to 2.0 GPM by 2024.
However, if you feel your shower delivers extremely low water compared to local laws. You can check the shower flow rate with a simple test.
Test to Check Water Flow Rate/Pressure from a Shower Head
This simple test can help you determine if your shower head meets efficiency standards and can also be useful if you’re looking to replace your shower head with a more water-efficient model.
Gather Materials: You’ll need a bucket (preferably one marked in gallons) and a stopwatch or timer.
Measure the Flow Rate
- Place the bucket under the shower head.
- Turn on the shower to the usual pressure you use.
- Time exactly one minute with the stopwatch.
- Turn off the shower and measure the amount of water in the bucket.
Calculate the Flow Rate: The amount of water collected in the bucket (in gallons) is the flow rate in gallons per minute (GPM). For instance, if you collect 1.5 gallons in one minute, your flow rate is 1.5 GPM.
Comparing with Standards: Compare your measured flow rate to standard flow rates. As per the federal standard, the maximum flow rate should be 2.5 GPM.
Why do People Prefer Shower Heads with Low Flow Rates?
Showering with a shower with a low flow rate may seem a bit frustrating and take more time to bath, but doing so is good fortune for all of us. There are a lot of models that are labeled as “Eco Performance” or “EP.” These models have a flow rate of 1.5 GPM, which is 40% less than the the 2.5 GPM flow rate. It saves a lot of water that can be used for various other purposes that are healthier than showering quickly.
Here are a few other benefits that may help you understand why it is a good idea to install water-efficientwater-efficient shower heads at your home.

Despite the initial cost of installation, water-efficient shower heads can lead to significant savings on water and energy bills over time. This makes them a cost-effective investment for homeowners.
Compliance with Regulations
Installing water-efficient shower heads helps in complying with state and federal water conservation standards. This is increasingly important as more regions adopt stringent water usage policies.
Reasons my Shower has a Low Pressure
Clogged Shower Head
Mineral deposits from hard water can accumulate in the shower head over time, blocking the flow of water. Regular cleaning or descaling of the shower head can prevent or resolve this issue.
Closed or Partially Closed Valves
The main water valve or the shower valve might not be fully open, which can restrict the flow of water. Ensuring these valves are completely open can often resolve pressure issues.
Faulty Plumbing
Leaks or damages in the pipes, especially hidden ones, can significantly reduce water pressure. Professional inspection and repair of the plumbing system may be required to address this problem.
Water Restrictor in Place
Many modern shower heads have water restrictors to conserve water. While eco-friendly, these restrictors can sometimes reduce water flow more than desired.
Low Municipal Water Pressure
Sometimes, the issue might be with the municipal water supply itself. If the water pressure is low throughout your house, this could be the cause.
Corroded Pipes or Plumbing Issues
Over time, pipes, especially older ones, can corrode or develop scale, narrowing the pathway for water and reducing pressure. Pipe replacement or repair might be necessary in these cases.
Peak Usage Times
Water pressure can drop during peak usage times in your area, like early mornings or evenings. This is more common in apartment buildings or densely populated areas.
How to Increase Water Pressure from a Shower Head?
Sometimes the water pressure inside your home is so slow that your shower hardly delivers any water. You may see a few drops of water that aren’t sufficient to wash your hair or remove soap. Here are a few tips to help you increase shower water pressure.
Clean the Shower Head
Mineral deposits and buildup can significantly reduce water flow. Detach the shower head and soak it in a vinegar solution for several hours, then use a small brush to scrub away any remaining deposits. This process helps to clear blockages in the nozzles, restoring water flow and pressure.
Check for and Repair Any Leaks
Leaks in the shower head or the pipes leading to it can cause a drop in water pressure. Inspect the shower head, the hose, and the connections for any signs of leakage. Tightening loose connections or replacing worn-out parts can effectively fix these leaks and improve water pressure.
Inspect the Water Lines
Reduced pressure might be due to issues in your home’s plumbing. Check if the shut-off valves are fully open, as partially closed valves can restrict water flow. If you suspect broader issues with your home’s plumbing, it may be wise to consult a professional plumber.
Install a Shower Pump
If low pressure is a systemic issue in your home, installing a shower pump can be an effective solution. A shower pump boosts the water flow to your shower, significantly improving the pressure. This solution is particularly relevant for homes with gravity-fed water systems.
Adjust or Remove the Water Restrictor
Most modern shower heads come with a water restrictor to conserve water. However, this can also reduce the water pressure. If you have already tried other methods and still face low pressure, consider adjusting or removing the water restrictor. This should be done carefully to avoid damaging the shower head.
Replace the Shower Head
If all else fails, replacing the shower head might be your best option. There are specific shower heads designed for low-pressure systems that can significantly improve water flow. When choosing a new shower head, look for one labeled as being high-pressure or designed for low water pressure systems.
