What Can Cause Low Water Pressure?
Dealing with a weak trickle instead of a strong flow from faucets and plumbing fixtures can be extremely inconvenient, making it harder and more time-consuming to wash hands, clean dirty dishes, and more, because the reduced water flow cannot effectively rinse away soap and debris. However, poor water pressure can also be a sign of an underlying issue that may require professional plumbing services. Identifying the underlying issue is the first step toward resolving the problem and restoring optimal water pressure.
Faulty Fixtures or Closed Valves
If the reduction in water pressure is localized, meaning it affects only one fixture, such as a single showerhead or faucet, the source of the trouble is likely that specific fixture. In many instances, the problem is a clogged aerator in the faucet or an accumulation of mineral deposits within the showerhead. Often, simply cleaning or replacing the plumbing fixture will solve the issue.
However, if diminished water pressure is throughout the property, the cause could be as simple as a valve that has been unintentionally closed or left partially shut, such as the main water shutoff valve or the water meter valve. An initial troubleshooting step is to inspect water valves and ensure they are fully open.
Water Leaks
A decrease in water pressure affecting all taps and fixtures in the house can also be a significant indicator of a leak in the water line. When water escapes through a water line leak or burst pipe, it diminishes the volume and force of the water that ultimately flows out of the fixtures.
While some leaks are easily spotted, others can occur hidden inside walls, under the home's foundation, or underground, making them difficult to locate. Beyond the loss of water pressure, an unexpected spike in the monthly water bill is another strong clue pointing to a leak. Promptly identifying leaks and calling for water leak repair is vital, not only to prevent structural damage and water waste but also to restore proper water pressure levels.
Clogs and Buildup
Over time, the inner diameter of a home's water pipes can narrow, resulting in frustratingly low water pressure. Blockages and accumulations in water lines can lead to this issue and may arise from old, corroded water pipes. As the metal degrades and rust forms, flakes can detach and accumulate, reducing the pipe's internal diameter and slowing water flow.
Another potential cause of narrowing water lines is limescale and mineral buildup, particularly in regions with hard water. The minerals present in hard water, such as magnesium and calcium, can form a hard, abrasive layer often referred to as scaling or limescale inside the pipes. This gradual accumulation effectively constricts the water line, reducing the water pressure.
