There’s nothing quite as frustrating as turning on a faucet only to be met with a disappointing trickle of water. Whether you’re trying to rinse dishes, take a shower, or water the lawn, low water pressure can put a damper on daily routines—and sometimes point to more serious plumbing issues. If you’re experiencing water pressure problems in your home, you’re not alone—and you’re not without solutions.
We’ve helped countless homeowners track down the causes of weak water flow and restore strong, steady pressure. Let’s break down the most common culprits, walk through a handy homeowner checklist, and explain how our expert plumbing team can help you get things flowing again.
Common Causes of Low Water Pressure
Low water pressure can stem from a variety of issues, some simple and others more complex. Here are the top reasons your water pressure might be lagging:
- Clogged faucet aerators or showerheads – Mineral buildup, especially in homes with hard water, can clog the small screens on faucets and showerheads. This reduces the water flow dramatically, often affecting only specific fixtures.
- Malfunctioning pressure regulator – Many homes have a pressure-reducing valve (PRV) that manages the overall water pressure entering the house. If this regulator fails or is set too low, it can cause weak flow throughout your home.
- Hidden leaks – Undetected plumbing leaks—whether inside walls, under the foundation, or in outdoor supply lines—can siphon off water before it reaches your fixtures. Leaks not only reduce pressure but can also lead to water damage and mold issues.
- Corroded or blocked pipes – Older homes, especially those with galvanized steel piping, may suffer from internal pipe corrosion. Over time, this reduces the interior diameter of the pipes, restricting water flow.
- Municipal supply issues – Sometimes, the problem isn’t in your home at all. City water systems may occasionally lower pressure due to maintenance, construction, or high demand. This can be verified by contacting your local water utility provider.
Homeowner Water Pressure Checklist
Before calling in the pros, you can try this quick checklist to identify or rule out common causes:
- Check multiple fixtures. Is the pressure low at one faucet or throughout the entire house?
- Clean faucet aerators and showerheads. Unscrew them and soak in vinegar overnight to dissolve mineral buildup.
- Inspect for leaks. Look for unexplained wet spots, moldy smells, or running water sounds behind walls or under sinks.
- Check your main shut-off valve. Make sure it’s fully open. A partially closed valve can restrict water flow.
- Ask your neighbors. If others are experiencing low pressure too, it may be a city supply issue.
If you’ve checked these items and the problem persists, it’s time to call the experts.
