5 Causes of Low Water Pressure in Your Faucets

Having low water pressure in your home can be more than just a nuisance. It can indicate a much bigger problem.

Low water pressure affects everything from taking a shower to washing dishes. Sometimes, the cause is something simple, like someone using water somewhere else in the home. Other times, though, the answer isn’t so obvious.

Here are the top five causes of low water pressure in your faucets and what you can do to fix it.

1. A Clogged Aerator

Every faucet contains an aerator, which is a small device that screws onto the end of the faucet and helps regulate water flow. Over time, it can become clogged with mineral deposits and debris, which can restrict water flow and cause low water pressure.

You can remove the aerator for cleaning, then replace it to see if it helps your water pressure issues. Soak the aerator in vinegar for five minutes, then use an old toothbrush to scrub it clean.

2. Leaks in Your Pipes

Leaks in the plumbing system can reduce water pressure. The more places where water is being used, the less pressure there is to go around. Check for leaks under sinks, around toilets, and in other areas of the home.

3. Corroded Pipes

Old, corroded pipes can restrict water flow and reduce water pressure. This is especially common in homes with galvanized pipes, which can corrode over time and become clogged with rust and mineral buildup. This buildup can also create rough surfaces on the interior of the pipe, which can cause turbulence and reduce water flow even more.

Corrosion can also cause pipes to weaken and develop leaks. These leaks can cause a loss of water pressure, as water is diverted away from its normal flow path and escapes through the leak.

4. A Faulty Pressure Regulator

A pressure regulator is a device that controls the water pressure in your home. If it becomes faulty or malfunctions, it can cause low water pressure or even high water pressure, which can damage your plumbing system.

The water pressure regulator is usually located near the main shut-off. It usually looks like a bell-shaped device or a cylindrical value with an adjustable screw. Test the water pressure regulator by turning off the main water supply and relieving the pressure in the system by opening a faucet. Remove the regulator from the pipes and inspect it for signs of damage or wear. Look for any cracks, corrosion, or other signs of damage.

You can also test the regulator by attaching a water pressure gauge to the regulator and turning the water supply back on. If the regulator is functioning correctly, it should maintain a consistent water pressure regardless of the flow rate.

5. Local Water Supply Issues

Sometimes, water pressure issues have nothing to do with your home and everything to do with your local water supplier. Municipal issues (e.g., water main breaks, water line repairs, high demand) are out of your control and will resolve themselves. Look for alerts on your local city websites and social media to know if there are current issues affecting the water pressure in your home.
