5 Common Causes of Low Water Pressure and How to Fix Them

A dripping faucet with low water pressure.

Did you turn on the kitchen faucet or shower only to find a slow trickle of water? Having low water pressure can be incredibly frustrating to deal with, especially if it’s getting in the way of your daily routine.

What causes low water pressure, and what can you do to fix this problem fast? Below, we’ll go over the five most common causes of low water pressure. Once you understand what can cause this issue, you can diagnose and fix it according to your specific needs.

Hidden Plumbing Leaks

You might not be surprised to discover that one of the most common causes of low water pressure is a plumbing leak. When a pipe is damaged or cracked, the flow of water will be disrupted. The leak can be anywhere in your home, such as beneath your sink or behind walls.

If you suspect a leak, shutting off the water to your home and calling a plumber should be your first courses of action. Even a small amount of water can cause significant damage. Your local Prosper plumbing experts can help you address the leak and minimize any water damage when you act fast.

Water Meter Value Issues

Your home’s water supply is commanded by two central valves: the main water shutoff valve and the water meter valve. You control the main water shutoff valve, while your local water company manages the other.

Both of these valves should be fully open. However, if any work has recently been performed at your house, one of these valves might be partially closed, resulting in low water pressure. This is one of the most common causes of low water pressure, but it’s fortunately easy to check. To inspect the shutoff valve, locate where the municipal water supply connects to your plumbing system — this is where you’ll find the valve. You’ll need to contact your water company if the issue is with the water meter valve. 

Damaged Pressure Regulator

If you want to fully understand what causes low water pressure, get to know your home’s water pressure regulator. This valve’s main objective is to supply your home with normal water pressure — a perfect medium that’s not too low and not too high.

Generally speaking, the water pressure should be around 75 pounds per square inch. If your water pressure is drastically below this, you could have a malfunctioning pressure regulator.

Corroded or Clogged Pipes

In the past, corroded pipes were one of the most common causes of low water pressure. This particular issue can still apply if your home is equipped with galvanized steel water pipes.

Although galvanized water lines used to be more popular and have widely been replaced, your home could still have them if the plumbing system hasn’t been updated in the last 30 years. Over time, these pipes can corrode and develop leaks that drastically restrict water flow. You will need to replace any corroded pipes if you want to fix your water pressure.

Faulty Plumbing Fixtures

When discussing what causes low water pressure, you might not immediately think about your plumbing fixtures. However, blocked or faulty fixtures can easily wreak havoc on your water pressure, making washing dishes and other routine tasks difficult.
