Keeping Your Home’s Water Pressure High

Strong, consistent water pressure makes everyday tasks like showering, washing dishes, and doing laundry easier and more enjoyable. When water pressure drops, it can be frustrating and may signal an underlying plumbing issue. Understanding what affects water pressure and how to maintain it can help keep your plumbing system performing at its best.
Common Causes of Low Water Pressure
Low water pressure can be caused by several factors, including mineral buildup in pipes, partially closed shutoff valves, aging plumbing, or hidden leaks. In some cases, municipal water supply issues or pressure regulators can also contribute to reduced flow throughout the home.
Check Your Main Shutoff Valve
One of the simplest ways to improve water pressure is to make sure your main shutoff valve is fully open. This valve is often located near where the water line enters your home. If it is partially closed, it can restrict water flow and reduce pressure at your fixtures.
Inspect Individual Fixture Valves
Low pressure at a single faucet or shower often points to a localized issue. Check the fixture’s shutoff valves under sinks or behind toilets to ensure they are fully open. These valves can be accidentally turned down during repairs or maintenance.
Clean Faucet Aerators and Showerheads
Mineral deposits and debris can build up in faucet aerators and showerheads, restricting water flow. Removing and cleaning these components regularly can restore proper water pressure and improve overall performance.
Look for Hidden Leaks
Undetected leaks can reduce water pressure while increasing your water bill. Check for damp spots, water stains, or the sound of running water when no fixtures are in use. Addressing leaks promptly helps maintain strong pressure and prevents water damage.
Check Your Pressure Regulator
Homes with a pressure reducing valve rely on this device to regulate incoming water pressure. If the regulator fails or is set too low, it can limit pressure throughout the house. A plumber can test and adjust or replace the regulator if needed.
Consider Pipe Condition and Age
Older plumbing systems may have pipes narrowed by corrosion or mineral buildup, especially in galvanized steel lines. Over time, restricted pipe diameter reduces water flow and pressure. In these cases, repiping or targeted pipe replacement may be the best long-term solution.
Maintain Your Water Heater
Low hot water pressure can be caused by sediment buildup inside the water heater or at the hot water outlet. Flushing the water heater regularly helps maintain proper flow and ensures consistent pressure for hot water fixtures.
Upgrade Fixtures for Better Performance
Some older or low-quality fixtures are not designed for optimal flow. Upgrading to modern, high-efficiency fixtures can improve water delivery while still conserving water. A plumber can recommend fixtures that balance performance and efficiency.
Know When to Call a Professional
If you experience sudden or widespread drops in water pressure, it is important to contact a licensed plumber. Professional inspection can identify issues such as pipe damage, failing regulators, or system-wide restrictions that require expert repair.
Enjoy Strong, Reliable Water Pressure
Keeping your water pressure high involves a combination of regular maintenance, timely repairs, and proper system setup. By staying proactive and addressing small issues early, homeowners can enjoy consistent water pressure and avoid costly plumbing problems down the road.
