Why Is My Water Pressure Low? How Do I Fix It?

If you’re currently dealing with low water pressure in your home, then you know how frustrating this particular issue can be. As you may have experienced firsthand, low water pressure can make it difficult to thoroughly clean your dishes, rinse the shampoo from your hair, or fill your washing machine with water — among other daily tasks.

Are you wondering why your water pressure is low? The excellent news is that you can usually troubleshoot this problem all on your own. The bad news is that there are several potential reasons why this issue is occurring, so it might take some sleuthing.

Let’s go over some of the most common reasons for low water pressure in a home.

Closed Shutoff Valve

If you’re dealing with low water pressure all throughout the house, you should check your home’s main shutoff valve first. It’s possible that this valve has become partially closed and is limiting the amount of water you’re receiving at your faucets and plumbing fixtures.

This is one of the most frequently-encountered reasons for low water pressure. A plumber may have shut off the water at this valve during a repair and forgot to open it back up. You’ll want to locate this valve outside your home and check that it’s fully open.

Although you may have checked your main water valve and found nothing amiss, it’s important to recognize that your home has two shutoff valves. The second valve (called the “water meter valve”) is controlled by your local water company, so if you suspect there’s something wrong with it, don’t hesitate to call them.

Faulty Water Pressure Regulator

A broken or malfunctioning water pressure regulator could also be why your water pressure is low. As the name indicates, a water pressure regulator is responsible for maintaining an even, consistent water pressure throughout your home. Without one of these valves, your water pressure could reach unsafe levels and damage your plumbing system.

Not all homes are equipped with water pressure regulators. However, if you have one of these valves, you can perform a quick test to determine if it’s working correctly. You’ll need to attach a water pressure gauge to one of your outdoor faucets that’s in close proximity to the pressure regulator. If the water pressure gauge gives you a lower reading than the regulator, then it might be time for a replacement.

Water Heater Problems

Do you only notice water pressure problems when using hot water? If this is the case, there’s a good chance that the issue lies with your water heater. First and foremost, you should check to ensure that the water shutoff valve is open and isn’t fully or partially closed.

If you’re certain the shutoff valve isn’t the culprit, you could be dealing with sediment buildup at the bottom of your water heater tank. As fresh water enters the tank to be warmed up, it can contain a multitude of minerals that end up settling at the bottom of the tank. This sediment, as it builds up over time, can lead to water pressure problems.

You’ll want to contact a professional plumber ASAP, as sediment buildup can lead to excessive wear and tear, prompting the need for a water heater repair in Dallas-Fort Worth, TX. Although this particular problem is one of the most common reasons for low water pressure, it can also shorten your water heater’s lifespan.

Old, Corroded Pipes

If you’re still wondering why your water pressure is low, consider the possibility that your pipes are at fault. Older pipe materials, such as galvanized steel, can corrode over time. As these pipes wear away, they form a layer of scaling that can restrict the flow of water.

Although corrosion clogs pipes and can negatively impact the water pressure in your home, it’s important to recognize that this plumbing problem can lead to various other issues, such as leaks and costly water damage. Other signs of corroded pipes include a foul smell and discoloration in your home’s water supply.

Hidden Plumbing Leaks

Sure, there are many reasons for low water pressure — but hidden plumbing leaks are some of the most concerning. Leaks can lurk anywhere, including behind walls and beneath sink cabinets. It can be challenging to identify and locate these leaks, which can lead to extensive water damage and the need for expensive repairs.
