What Causes Low Water Pressure

If you have ever rinsed dishes under a trickle of water or gotten a few drips when trying to fill a glass of water, then you know the inconveniences that come with low water pressure. Toilets may take forever to refill, or taking a shower may be a less-than-refreshing experience. Either way, low water pressure can turn simple tasks into a hassle. In this article, you’ll learn about the common causes of low water pressure and how to resolve low water pressure in your home.

Using Too Many Water-Using Appliances at Once

Running multiple water-intensive appliances simultaneously can strain your water supply system. When the demand for water exceeds the system's capacity, you’ll experience reduced water pressure. This is particularly noticeable in older homes with smaller water heaters or undersized pipes. To alleviate this issue, stagger the use of appliances and consider upgrading your water heater.

Main Valve Is Slightly Closed

The main water supply valve controls the water flow into your home. If it's partially closed, it will restrict the water volume. Over time, sediment or mineral deposits can cause the valve to stick or become partially closed. To resolve this, fully open the valve and clean any debris. If the issue persists, the valve might need replacement.

Pressure Regulator Is Broken

If the main valve is fully open, check if the pressure regulator is in good working condition. A pressure regulator maintains consistent water pressure within your home. If it malfunctions, it can cause either low or high pressure. A broken regulator might not be regulating pressure effectively, leading to reduced water flow. Inspect the regulator for damage and replace it if necessary.

Water Softener Issues

A failing water softener can also contribute to low water pressure if not maintained properly. Issues like salt depletion, resin exhaustion, or a malfunctioning control valve can reduce water flow. Regular maintenance can help identify and resolve these problems. An experienced plumber can help you keep your water softener in tip-top shape.

Corroded or Clogged Water Lines

Over time, water pipes can accumulate mineral deposits, rust, or corrosion, especially if you have hard water. This can reduce their internal diameter and restrict water flow. If you’ve noticed signs of pipe corrosion in your home, call a trusted plumbing repair service for pipe replacement.

Clogged Screen in the Aerator or Shower Head

Aerators and showerheads contain screens that filter water and mix it with air to create a more forceful stream. Mineral buildup or debris can clog these screens and reduce water flow. Unscrewing the aerator or showerhead and cleaning the screen can often restore water pressure. If the problem persists after cleaning the fixture, call a reputable plumbing service to perform an inspection.

Leaking Water Pipes

Leaking pipes can significantly reduce water pressure. The water escaping from the leak decreases the overall water volume available to your fixtures. Signs of leaks include damp spots, unusual water sounds, or unexplained increases in your water bill. If you notice any of these signs, call a nearby plumber for leak detection and repair. Locating and repairing leaks in a timely manner is crucial to restoring normal water pressure.

Outdated Fixtures

Older plumbing fixtures such as faucets and showerheads often have smaller openings and less efficient designs, which can lead to reduced water flow. You’re more likely to have outdated fixtures if you live in an older home. Reach out to a professional plumbing repair service to upgrade your fixtures and improve water pressure and water efficiency.
