Some problems show up in life unannounced. They don’t give us a heads-up or wait until it’s convenient to strike. Instead, they barge in and demand immediate attention. Low water pressure is one of those issues. You notice it instantly — washing dishes takes forever, showers are unsatisfying, and even filling a pot can feel like a chore. For something as essential as water in your home, having low pressure can disrupt your day in big ways.
If you’re experiencing low water pressure, it’s time to uncover what’s causing the issue. Below, we’ll break down the common causes of low water pressure, what they mean for your home, and what you can do about it.
What Is Considered Normal Water Pressure?
Water pressure is measured in pounds per square inch (psi). For most homes, typical water pressure ranges between 40 and 60 psi. If the water pressure in your home dips significantly below this range, it could lead to noticeable issues when you’re showering, washing dishes, or simply turning on a faucet.
If the water pressure is low, it’s a sign that something in your plumbing system isn’t working properly. The good news? Once you identify the problem, it’s usually fixable.
Common Causes of Low Water Pressure
If you’re experiencing low water pressure, it’s important not to overlook it. While the issue can be perplexing for homeowners, knowing the common causes of low water pressure can help you identify the root of the problem. Let’s explore the usual culprits and how to get things flowing smoothly again.
Partially Closed or Malfunctioning Valves
A main house shutoff valve or water meter valve that’s partially closed is a common reason for low water pressure in your house. These valves control how water flows into your home. If they’re not fully open, water flow can be restricted, resulting in noticeably less pressure at your faucets and shower heads.
Check these valves to see if they’re fully open. Sometimes, a simple adjustment is all you need to restore proper water pressure.
Leaking Pipes
Leaky pipes or more than one leak in your home could also be why your water pressure is low. When water escapes from damaged pipes, it reduces the amount of water that reaches your fixtures. Leaks can happen due to old or corroded plumbing, cracks, or even freezing temperatures that cause a burst pipe.
Keep an eye out for signs of leaks, like water stains, damp areas, or an unusually high water bill. Andreas Plumbing, Heating & Air Conditioning can help you locate the issue with professional leak detection in Lehighton, PA, or one of the surrounding areas.
Clogged Pipes or Plumbing Fixtures
Over time, mineral deposits and debris buildup can form inside pipes and fixtures, causing a restricted flow of water. This is particularly common in areas with hard water. Clogged pipes and shower heads are notorious for causing low flow, making everyday tasks like washing dishes or taking a shower feel frustrating.
Cleaning out clogged fixtures or replacing old, galvanized pipes with newer materials like copper pipes can help water flow freely again.
Problems With the Water Supply Company
Sometimes, the issue isn’t inside your home but with the local water supplier or municipal water supply. Low pressure can happen if there’s a problem with the water company, such as maintenance work, a break in a water pump, or high water demand in your neighborhood.
Reach out to your water supplier to check if there are issues affecting your area.
Faulty or Broken Pressure Regulators
Your home’s water pressure regulator is designed to maintain proper water pressure. If it’s malfunctioning, you might notice high water pressure in some cases or low water pressure in others.
If you suspect a broken pressure regulator, a plumber can test and replace it to restore normal pressure levels.
Corroded Pipes
In older homes, pipes made of galvanized steel are prone to pipe corrosion over time. This corrosion can reduce the pipe’s internal diameter, restrict water flow, and cause low pressure. Replacing galvanized pipes with modern alternatives, such as brass pipes or copper pipes, is a long-term solution to this problem.
Water Heater Issues
If you’re only experiencing low pressure when using hot water, your water heater might be to blame. Sediment buildup inside the heater or issues with the heater’s connections can restrict water flow and result in low pressure. Flushing your water heater regularly can prevent sediment buildup and keep it functioning optimally.
How to Diagnose Low Water Pressure in Your Home
If you’re still wondering why the water pressure is low, here’s a quick checklist to help you pinpoint the problem:
- Check All the Faucets: Is the pressure low at a single faucet, or throughout the house? If it’s isolated, the issue might be with the fixture.
- Inspect the Valves: Make sure your water valves are fully open, including the hose spigot and branch lines.
- Look for Leaks: Watch for signs of leaks around the home.
- Use a Pressure Gauge: A pressure gauge can measure your home’s water pressure to determine if it’s outside the normal range.
- Call a Plumber: For persistent problems or issues like clogged water pipes or a malfunctioning pressure regulator, call in professionals like Andreas Plumbing, Heating & Air Conditioning.
