Low Water Pressure in Your Home: Causes and Solutions

Low water pressure turns a simple shower into a frustrating experience. The cause can range from a minor fixture issue to a serious supply problem. Here's how to diagnose it.

Is it one fixture or the whole house?

Start by checking whether the low pressure affects a single faucet or every fixture. A single slow faucet usually means a clogged aerator or cartridge. House-wide low pressure points to a bigger supply issue.

Common causes

• Clogged aerators or showerheads from mineral buildup
• Corroded or narrowed galvanized pipes
• A partially closed main shut-off or pressure-reducing valve
• Hidden leaks bleeding off pressure
• Municipal supply issues

Quick fixes you can try

Unscrew and soak aerators and showerheads in vinegar to dissolve mineral deposits. Confirm your main valve is fully open. If pressure is still weak everywhere, the problem likely needs professional diagnosis.
