Troubleshooting Low Water Pressure in the Shower

Over time, a variety of different issues may afflict your showerhead. This can lead to low water pressure, which can make it very difficult for you to clean yourself and generally reduces your comfort levels in the shower. Being aware of some of the most common reasons why your shower's water pressure may have suddenly dropped can help you figure out the next best steps to take in order to fix the underlying issues.

Clogged Showerhead

The water pressure may have dropped in your shower specifically because of mineral buildup within the showerhead itself, which is caused by dissolved minerals and sediment within your water supply. You can unscrew your showerhead and soak it overnight in a mixture of one part white vinegar and two parts warm water to dissolve the buildup and restore the flow, though there are a number of cleaning chemicals available at most hardware stores that will do the same thing. Talk to a plumber about your options moving forward. Depending on the type of mineral buildup, it may be in your best interest to install a water filter within your home's plumbing supply to remove particles and minerals which can build up over time.

Damaged Water Pressure Regulator

Another reason why the water pressure in your shower may be low is because of a damaged or old water pressure regulator. These regulators are installed on your water main to reduce water pressure before it enters your home, as high water pressure can cause significant damage to your pipes and create leaks. Regulators may restrict your water pressure too much, which can lead to a dribbling showerhead. You'll be able to tell if this is the case if all of your taps and showers in your home are suffering from low water pressure. A plumber will be able to inspect and replace your regulator.

Water Valve Issues

If you have an older shower that has not had a new showerhead installed in a very long time, your shower may be suffering from a worn-out valve. Known as single-control valves or single-control showers, these valves control the flow of water out of your showerhead but are complicated internal mechanisms that can malfunction or clog over time. Usually, when this happens it indicates that your showerhead is overdue for a replacement, though you can also keep the showerhead and simply replace the valve if you prefer.
