Possible Causes of Low Water Pressure in the House

What Causes Poor Water Pressure?

Low water pressure in the house can be incredibly frustrating, especially when it hinders residents’ daily routines. However, low water pressure can be a warning sign of a larger plumbing issue in need of attention. This post will discuss possible reasons for poor water pressure so the underlying issue can be resolved.

Faulty Fixtures or Closed Valves

Troubleshooting low water pressure often begins with determining whether the problem affects a single plumbing fixture or fixtures throughout the home. When water pressure drops only at one fixture, such as a faucet or showerhead, the culprit is typically a faulty or clogged fixture rather than a systemic plumbing issue. Mineral deposits can gradually accumulate in aerators and showerheads, restricting water flow over time.

For whole-house water pressure problems, the hidden cause may be partially closed valves. The main water shutoff valve or water meter valve might have been accidentally left in a partially closed position after maintenance or repairs. These critical flow control points can dramatically impact a home's overall water pressure when not fully open. Locating and ensuring that valves are completely open can be the first step before calling a plumber. A quarter-turn ball valve should be parallel to the pipe when fully open, while older gate valves require multiple complete counterclockwise turns. The solution to water pressure woes might be as simple as a quick valve adjustment, fixture cleaning, or replacement.

Water Leaks

A water leak within a home's plumbing system can also be the culprit behind frustrating low water pressure problems. When water lines develop cracks or connections fail, water escapes before reaching plumbing fixtures, resulting in weakened flow throughout the house. After identifying these hidden issues, professional water leak repair can restore normal water pressure levels.

The severity of pressure loss typically correlates with the leak's size and location. A small drip might cause barely noticeable pressure reduction, whereas a major pipe rupture can leave the household with just a trickle from the faucets and fixtures. In addition to reduced water pressure serving as a warning sign of a water leak, higher-than-normal water bills can also point to a leak. To confirm a water leak, homeowners can check their water meter when no water is being used. After an hour with no water being used, check the meter again. If the reading has changed, it confirms there’s a leak. Prompt water leak detection and repair will restore water pressure and help prevent additional water damage and mold growth.

Clogs and Buildup

Mineral buildup and pipe clogs are other possible causes of low water pressure. Over time, water lines can accumulate debris, sediment, and mineral deposits that gradually restrict water flow. The reduction in pressure often occurs so gradually that homeowners don't notice until the problem becomes severe.

The aging process of plumbing infrastructure can also contribute to these blockages. Older galvanized pipes are particularly susceptible to internal corrosion, which creates rough surfaces where minerals readily attach. So, homes with older plumbing have a higher risk of experiencing pressure loss due to pipe corrosion. Hard water, containing high concentrations of minerals like calcium and magnesium, can also accelerate buildup inside water pipes. A professional can address these issues and restore the home’s water pressure.
