2 Possible Reasons Why Your Home Has Low Water Pressure

Posted on: 11 January 2023

Lately, you may have noticed that the pressure of the water coming out of your home's faucets has steadily started to decrease. After ruling out the possibility of a water leak, you may be wondering what could be causing the issue.

When your water pressure is low, first ask your neighbors if theirs are as well to rule out an external problem. If no one else is experiencing the problem, there are a couple of possible reasons why your home has low water pressure, both of which require the attention of a plumbing professional to remedy.

1. Plumbing's Water Pressure Regulator Has Started to Malfunction

One possible reason why the water pressure in your home has decreased could be an issue with the water pressure regulator. Located near the main shutoff valve that controls the water coming into your home, this regulator is supposed to help maintain consistent pressure throughout your house.

If the regulator starts to malfunction, you may have intermittent problems with low pressure. However, if it fails completely, the issue will be constant. A plumbing professional can examine the regulator to see if it is going bad and needs to be replaced. 

2. Water Intake Pipes' Interiors Are Caked with Minerals and Corrosion 

Another possible reason why your home's water pressure has steadily decreased is that there may not be enough space for the full amount and force of water to travel through the intake pipes. Especially if you live in an area with hard water, the minerals deposited on the insides of the pipes will build up over time.

Along with these mineral deposits, the interiors of the pipes will also start to corrode, which adds to the narrowing of the lines. A professional can determine if this is the issue causing the low water pressure and discuss with you possible solutions that may include cleaning them out or replacing them if the buildup is bad enough.

If your home has low water pressure and you know no major leaks are causing it, you need to have a professional check out the water pressure regulator to see if it is malfunctioning and needs to be replaced. They can also check the interiors of the pipes to see if they are closing up because the sides are caked with minerals and corrosion.

Contact a plumbing service in your area to set up an appointment to have them send someone to find the cause of the low water pressure and take steps to fix the issue.
