Why Is My Water Pressure Low? Common Causes and When to Call a Plumber

Turn on the shower and barely get more than a trickle? Or maybe your faucets suddenly don't have the pressure they used to.

Low water pressure is frustrating, but it can also be a sign that something in your plumbing system needs attention.

The key is figuring out whether the problem is happening at one fixture or throughout your entire home.

Why Is My Water Pressure Low?

Here are some of the most common reasons your water pressure may have dropped.

1. Clogged Faucet or Showerhead

Low pressure at just one faucet or shower? Start there.

Mineral buildup and debris can collect inside aerators and showerheads, restricting water flow. Cleaning the affected fixture may be enough to get the water flowing normally again.

2. Pressure Regulator Problem

Some homes have a pressure regulator that controls the water pressure entering the house.

When it isn't working properly, you may notice a sudden drop or other changes in water pressure throughout your home.

A plumber can test the pressure and determine whether the regulator needs adjustment or replacement.

3. Hidden Plumbing Leak

A leak can reduce the amount of water reaching your faucets and fixtures.

Keep an eye out for other warning signs, including:

• Higher water bills

• The sound of running water when everything is turned off

• Unexplained wet areas around your home

If you notice any of these signs along with low water pressure, it's worth having your plumbing inspected.

One Fixture or the Whole House?

If one faucet or shower has low pressure, the issue may be with that specific fixture.

If the entire house has low pressure, the problem could involve your main valve, pressure regulator, plumbing pipes, a leak, or even the municipal water supply.

When Should You Call a Plumber?

If cleaning the faucet or showerhead doesn't fix the problem, or the pressure is low throughout your home, it's time to take a closer look.

A plumber can check your water pressure, valves, pipes, and other components to find the source of the problem instead of guessing.
