Dealing with low water pressure at home can be a frustrating experience, turning everyday activities like washing and cooking into a hassle. This issue can arise due to several common causes. While a plumber can help you restore normal water pressure, keep the following information in mind to identify the cause and correct the issue.

What Causes Poor Water Pressure?

1. Partially Opened Water Valves

Modern homes are equipped with two valves controlling the flow of water. The main shutoff valve allows water to flow freely into your pipes when fully opened. A common cause of low water pressure is a partially closed shutoff valve restricting the passage of water. Locate your shutoff valve and ensure that it’s completely open to restore water pressure.

The second valve controlling water flow is the water meter valve, a device usually owned and operated by your water provider. If your water has slowed to a trickle, it’s possible that this valve was left partially closed after the installation or recent work. These are often difficult to access, so contact your water company to ask for assistance in assessing the issue.

2. Faulty Pressure Regulator

Residential water pressure should typically stay below 60 pounds per square inch (PSI) and above 40 to 45 PSI. However, if the water in your area is supplied outside of this range, your plumbing may be equipped with a water pressure regulator to bring it to a safe, efficient level.

If you’re experiencing low pressure in spite of a regulator’s presence, it could mean that the regulator is damaged or failing. To check whether this is the case, attach a water gauge to an outdoor hose spigot and turn on the water. If the readings from the gauge and the regulator don’t match, consult a plumber for repairs or replacement to restore normal water pressure.

3. Corroded Pipes

In homes with older plumbing, a leading cause of low water pressure is corrosion. Galvanized steel pipes can begin to corrode in as little as 20 years with continual use, and while copper and brass can last for up to 100 years, they too will eventually break down.

Once corrosion sets in, your pipes will gradually weaken, spring leaks, and even build up obstructions which may slow the passage of water at normal pressure. If your pipes haven’t been replaced in more than 20 years, have a plumber inspect them to determine if corrosion is the cause of lost pressure.
