Low water pressure in the shower is a common problem with simple causes. It might be mineral buildup, a clogged showerhead, or a valve that isn’t fully open. In some cases, it’s a sign of bigger issues in your plumbing system. You may wonder, "How can I increase the water pressure in my shower?" This blog covers the most common causes of low shower water pressure and offers seven clear ways to increase water pressure in shower. If your shower isn’t performing like it should, these steps will help you fix it quickly and effectively.
Common Causes of Low Water Pressure in Shower
Low shower pressure usually points to a simple issue that can be fixed before it turns into something bigger. Here are the most common reasons:
- Clogged Showerhead: Over time, mineral deposits, especially in hard water areas, build up and block the spray nozzles.
- Flow Restrictors: Many modern showerheads come with built-in flow restrictors to save water, which often reduces pressure significantly.
- Aging Pipes: Corroded or narrow pipes, like older galvanized steel, can limit water flow.
- Hidden Leaks: Even small pipe leaks behind walls or under floors can reduce water pressure in specific areas.
- Municipal Water Supply Limits: If your whole house experiences low pressure, it could be your local water supply, especially during peak usage hours.
- Faulty Pressure-Balancing Valve: A malfunctioning valve can cause an imbalance in hot and cold water, reducing overall pressure.
- Low-Pressure Water Heater: When only the hot water has low pressure, it’s often an issue with the heater, such as sediment buildup or failing valves.
How to Increase Water Pressure in Shower?
Now that you know the potential causes, let’s get into the actionable part: how to change water pressure in shower. These seven tips range from basic DIY tricks to more involved upgrades, allowing you to choose what fits your situation best.
Method 1. Clean or Replace the Showerhead
Low water pressure in the shower is often caused by a clogged or outdated showerhead. Luckily, this is one of the simplest fixes you can try before calling in bigger solutions. Cleaning or upgrading your showerhead can quickly improve flow and make showers more comfortable without increasing water use. Options like rainfall or handheld MyHomeware showers, many of which are WELS-rated for efficiency and designed with anti-clog nozzles, offer an easy way to boost performance while staying water-smart.
Steps:
- Remove the showerhead.
- Soak it in vinegar for a few hours to dissolve mineral buildup.
- Scrub the spray holes with a brush.
- Reattach and test the flow.
- If pressure is still low, replace it with a high-pressure or pressure-boosting model.
Method 2. Remove the Flow Restrictor
Many showerheads include a built-in flow restrictor to conserve water. While useful for saving resources, it can reduce pressure to an uncomfortable level. If your shower feels weak, removing the restrictor is a simple way to restore stronger flow—just be sure to check local codes first, as altering it may not always be permitted.
Steps:
- Unscrew and disassemble the showerhead.
- Find the small colored plastic insert (the restrictor).
- Use tweezers or a small screwdriver to carefully remove it.
- Reassemble the showerhead.
- Turn on the water and test the new flow.
Method 3. Install a Shower Pump
If your home suffers from consistently low pressure, common in older or multi-story houses, a shower pump can be an effective long-term fix. These pumps use a motor to boost flow across the system.
Steps:
- Choose a pump designed for your system (mixer, gravity-fed, or electric).
- Shut off water and power.
- Install the pump at the recommended location.
- Connect plumbing and electrical safely.
- Test the system for leaks and performance.
Note: Because installation requires both plumbing and electrical work, most homeowners hire a licensed plumber.
Method 4. Check the Plumbing Valve
A main water valve that isn’t fully open can choke the flow to every faucet and shower in the house. It’s a common oversight after plumbing work. Checking and fully opening the valve is a quick, no-cost step before considering larger repairs.
Steps:
- Locate your home’s main water shut-off valve (usually near the meter or where the line enters the house).
- Inspect the handle or lever.
- Turn it fully counterclockwise (or to the open position).
- Test the shower pressure.
- If pressure improves, you’ve found the culprit.
Method 5. Check for Hidden Leaks
Even small leaks can lower water pressure and lead to expensive damage. Watch for signs like damp spots, mold, water stains, or unusually high bills. If you suspect a hidden leak, call a professional to locate and repair it. Stopping leaks not only restores pressure but also protects your home.
Here is how to check the leak:
- Watch for mold, stains, or musty odors.
- Review recent water bills for unusual spikes.
- Inspect visible pipes for drips.
- If leaks are suspected, call a plumber.
Method 6. Upgrade to a High-Pressure Showerhead
Some showerheads are designed for homes with low flow. They use narrower spray patterns or built-in pressure-boosting features to deliver a stronger stream without increasing water use. They’re easy to install and provide immediate results.
Steps:
- Purchase a high-pressure showerhead.
- Remove the old showerhead.
- Wrap plumber’s tape around the pipe threads.
- Screw on the new showerhead.
- Turn on water and test the flow.
Method 7. Shower at Off-Peak Hours
Water pressure can drop when many homes in the neighborhood are using water at once, usually early morning or evening. If your shower only struggles during these hours, try adjusting your routine. Showering mid-day or later at night often gives you steadier pressure. It’s not always convenient, but it can be an effective workaround.
Conclusion
Low shower pressure has many simple solutions. Clearing buildup, checking valves, or repairing leaks can restore steady flow, while pumps and high-pressure heads provide longer-term fixes. Learning how to increase water pressure in shower helps you handle problems quickly and keep water running as it should. For reliable, well-designed options that support both performance and efficiency, take a look at MyHomeware showers.
FAQs
Will removing the flow restrictor damage my water usage or regulations?
Removing the flow restrictor can increase water usage, which might conflict with local plumbing codes or sustainability efforts. It could also raise your water bill over time. Always check your local water regulations before removing any built-in restrictors from plumbing fixtures.
Can I install a shower pump myself, or should I hire a plumber?
Installing a shower pump takes both plumbing and electrical skills. If you’re not experienced with both, it’s best to call a licensed plumber. Professional installation ensures the pump works properly, meets safety codes, and protects your home from costly mistakes.
How often should I clean my showerhead to maintain good pressure?
You should clean your showerhead at least once a month to avoid mineral buildup that restricts flow. In areas with hard water, more frequent cleaning may be necessary. Regular maintenance helps maintain consistent water pressure and extends the life of the fixture.
