What You'll Learn
Adjusting the Pressure Regulator Valve
To adjust the pressure regulator valve, start by removing the cover or protective cap that may be hiding the adjustment screw. Use your wrench or pliers to turn the screw clockwise to decrease the water pressure. Turning it clockwise reduces the force at which water is delivered to your shower and other fixtures. It’s important to make small adjustments and test the water pressure after each turn to avoid over-tightening, which could lead to insufficient water flow. If the screw is difficult to turn, apply steady pressure but avoid forcing it to prevent damage.
After making the adjustment, turn the main water supply back on and check the shower pressure. If the pressure is still too high, repeat the process by turning the screw clockwise in small increments. Conversely, if the pressure is too low, turn the screw counterclockwise to increase it. Keep in mind that the ideal water pressure for residential homes is typically between 45 and 55 psi (pounds per square inch). You can use a pressure gauge to measure the pressure accurately if needed.
If your American Standard shower still has high water pressure after adjusting the regulator valve, inspect the valve for signs of wear or damage. Over time, pressure regulator valves can fail or become less effective, requiring replacement. Consult the manufacturer’s instructions or a professional plumber if you suspect the valve is malfunctioning. Proper maintenance of the pressure regulator valve not only ensures a comfortable shower experience but also protects your plumbing system from potential damage caused by excessive pressure.
Finally, remember that adjusting the pressure regulator valve affects the entire plumbing system in your home, not just the shower. Ensure that reducing the pressure doesn’t negatively impact other fixtures. If you’re unsure about making these adjustments yourself, it’s always a good idea to consult a licensed plumber. They can provide expert guidance and ensure the changes are made safely and effectively, tailored to your American Standard shower and overall plumbing setup.

Replacing the Restrictor Flow Device
To begin the process, start by turning off the water supply to the shower to avoid any accidental spills or leaks. This can usually be done by locating the shut-off valves near the shower or at the main water supply. Once the water is off, remove the showerhead by unscrewing it counterclockwise from the shower arm. If it’s difficult to remove, use a cloth or rubber grip to prevent damaging the finish. After removing the showerhead, inspect it for the restrictor flow device, which is often a small plastic or rubber component located inside the showerhead or at the entrance of the showerhead’s nozzle.
If the restrictor flow device is inside the showerhead, you may need to disassemble the showerhead further. Carefully pry open the showerhead casing using a flathead screwdriver, being cautious not to apply too much force to avoid breaking any parts. Once open, locate the restrictor flow device, which is typically a small disk or washer with a hole in the center. Remove the existing device by gently lifting it out with pliers or tweezers. If you’re replacing it, insert the new restrictor flow device, ensuring it is properly seated and aligned with the water flow path.
In some cases, the restrictor flow device may be located in the shower valve cartridge rather than the showerhead. To access this, you’ll need to remove the shower handle and escutcheon plate to expose the valve cartridge. This may require unscrewing a screw or prying off a cap, depending on your shower model. Once the cartridge is accessible, look for the restrictor flow device, which may be integrated into the cartridge or located nearby. Carefully remove or replace it, ensuring not to damage any other components in the process.
After replacing or removing the restrictor flow device, reassemble the showerhead or valve cartridge in the reverse order of disassembly. Reattach the showerhead to the shower arm, ensuring it is tightened securely but not overly tightened to avoid damage. Turn the water supply back on and test the shower to ensure the water pressure has been reduced to your desired level. If the pressure is still too high, consider further adjustments or consult a professional plumber for additional solutions. Replacing the restrictor flow device is a cost-effective and efficient way to manage water pressure in your American Standard shower.

Checking for Clogged Showerheads
If you're experiencing high water pressure in your American Standard shower, one of the first steps to consider is checking for clogged showerheads. Over time, mineral deposits, sediment, and debris can accumulate in the showerhead, restricting water flow and potentially increasing pressure. Start by visually inspecting the showerhead for any visible signs of buildup, such as white or yellowish deposits around the nozzles. These deposits are often calcium or lime scale, which are common in areas with hard water. If you notice any buildup, it’s a clear indication that the showerhead may be clogged and needs cleaning.
To further check for clogs, remove the showerhead from the shower arm. This can usually be done by unscrewing it by hand or using a wrench if it’s tightly secured. Once removed, inspect the interior of the showerhead for any blockages. Pay close attention to the small nozzles where water exits, as these are the most common areas for clogs to form. You can use a flashlight to get a better view of the internal components. If you see any obstructions, such as mineral deposits or debris, this confirms that the showerhead is clogged and needs to be cleaned to reduce water pressure.
After inspecting the showerhead, test its flow by holding it under running water or submerging it in a bowl of water. If the water flow is uneven or some nozzles are not releasing water at all, this is a strong sign of clogging. Uneven flow indicates that certain pathways within the showerhead are blocked, forcing water through fewer openings and potentially increasing pressure. This test helps you pinpoint the specific areas that require cleaning to restore proper water flow and reduce pressure.
Cleaning the showerhead is a straightforward process that can effectively reduce water pressure. Fill a plastic bag with white vinegar and secure it over the showerhead using a rubber band, ensuring the nozzles are fully submerged. Let the showerhead soak for at least an hour, or overnight for severe clogs. The vinegar will dissolve mineral deposits and break down debris. After soaking, remove the bag, scrub the nozzles gently with a toothbrush or pin to dislodge any remaining buildup, and rinse the showerhead thoroughly. Reattach it to the shower arm and test the water flow. If the clog is cleared, you should notice a reduction in water pressure.
Regular maintenance can prevent future clogs and help manage water pressure in your American Standard shower. Consider cleaning the showerhead every few months, especially if you have hard water. Additionally, installing a water softener can reduce mineral buildup in your plumbing system. By routinely checking for and addressing clogged showerheads, you can ensure a consistent and comfortable water flow while avoiding excessive pressure.

Installing a Pressure-Reducing Valve
Start by locating your home’s main water supply line, typically found near the water meter or where the main line enters your house. Once identified, shut off the water supply and open a faucet to relieve any remaining pressure in the system. Next, cut into the supply line where you plan to install the PRV. Use a pipe cutter or hacksaw to make clean, straight cuts, ensuring a proper fit for the valve. Clean the edges of the cut pipes to remove any burrs or debris that could interfere with the installation.
Now, prepare the pressure-reducing valve for installation. Wrap the threads of the valve and the connecting pipes with Teflon tape to create a watertight seal. Follow the manufacturer’s instructions for assembling the PRV, as designs may vary. Typically, the valve will have an inlet and outlet side, so ensure it is oriented correctly in the water flow direction. Secure the valve to the pipes using adjustable wrenches, being careful not to overtighten, as this can damage the threads or the valve itself.
After the PRV is installed, turn the main water supply back on slowly and check for leaks around the connections. If leaks are detected, tighten the connections slightly or add more Teflon tape. Once the system is leak-free, adjust the pressure-reducing valve to your desired setting. Most PRVs have a screw or adjustment knob that allows you to calibrate the output pressure. Use a pressure gauge to monitor the pressure and make adjustments until it reaches the recommended range, typically around 40-60 PSI for residential use.
Finally, test the water pressure in your American Standard shower to ensure it meets your expectations. If the pressure is still too high, further adjust the PRV. If it’s too low, you may need to fine-tune the valve or consult a professional plumber. Installing a pressure-reducing valve not only improves your shower experience but also protects your plumbing system from potential damage caused by excessive pressure. With careful installation and proper adjustment, you can enjoy a safer and more efficient water supply throughout your home.

Inspecting and Replacing Faulty Cartridges
When addressing high water pressure in an American Standard shower, one of the most effective steps is inspecting and replacing faulty cartridges. The cartridge is a critical component in the shower valve that regulates water flow and temperature. Over time, it can wear out, become clogged, or malfunction, leading to increased water pressure. Start by turning off the water supply to the shower to avoid any accidents during the inspection. Locate the shower handle and remove it by unscrewing the screw or prying off the cap, depending on the model. Once the handle is removed, you’ll have access to the cartridge, which is typically held in place by a retaining clip or screw.
Carefully inspect the cartridge for signs of damage, such as cracks, mineral buildup, or worn-out seals. Mineral deposits from hard water can restrict water flow, causing the valve to work harder and increase pressure. If the cartridge appears damaged or clogged, it’s time to replace it. Use a cartridge puller tool to gently extract the old cartridge, ensuring you don’t damage the valve body. Clean the valve opening with white vinegar or a descaling solution to remove any remaining debris or mineral deposits. This step is crucial to ensure the new cartridge operates smoothly and doesn’t immediately become clogged.
Next, install the new cartridge by aligning it properly with the valve opening. Refer to the American Standard model-specific instructions for the correct orientation, as improper installation can lead to leaks or continued pressure issues. Secure the cartridge with the retaining clip or screw, ensuring it’s firmly in place. Reattach the shower handle and turn the water supply back on to test the system. Run the shower and check for any leaks around the handle or valve. If the water pressure remains high, the issue may lie elsewhere, such as in the pressure regulator or supply line.
Replacing a faulty cartridge not only helps reduce water pressure but also improves the overall performance and longevity of your shower system. It’s a cost-effective solution compared to replacing the entire valve assembly. Regular maintenance, such as periodic inspections for mineral buildup, can prevent future cartridge failures. If you’re unsure about the process, consult the American Standard user manual or seek assistance from a professional plumber to ensure the job is done correctly.
Finally, after replacing the cartridge, consider installing a pressure-reducing valve (PRV) at the main water supply if high pressure persists. This additional measure ensures that all plumbing fixtures in your home are protected from excessive pressure, which can cause long-term damage. By combining cartridge replacement with other pressure-reducing strategies, you can achieve optimal water flow and efficiency in your American Standard shower.
