Understanding Water Pressure

Water pressure refers to the force at which water flows through your home’s plumbing system. It is typically measured in pounds per square inch (PSI) and is determined by the amount of water that can be pushed through your pipes at a given time. Normal water pressure ranges between 40 and 60 PSI, with 50 PSI being ideal.

If you experience low water pressure in your home, it can lead to issues like weak showers, slow-filling appliances, or even complete water flow stoppages. Understanding the factors that contribute to water pressure and how to properly measure it can help you identify any problems and take steps to increase the pressure if necessary.

To measure your home’s water pressure, you can use a pressure gauge that attaches to an outdoor water spigot. First, ensure all water fixtures in the house are turned off, then attach the gauge to the spigot and turn the water on. The gauge will provide an instant reading of the pressure in PSI. If your reading is lower than 40 PSI, it’s possible that the city is delivering water at low pressure, or there could be an issue with your home’s plumbing.

A common reason for low water pressure is the presence of partially closed or faulty shut-off valves near your water meter. These can restrict the flow of water, causing less pressure throughout the system. Check that these valves are fully open or replace them if necessary.

Another factor that may impact water pressure is the pipe diameter in your plumbing system. Larger pipes can deliver more gallons of water per minute, increasing the overall water pressure. However, it’s important to note that replacing your pipes can be an expensive and time-consuming process. Before considering this option, consult with a plumber to evaluate your existing system and determine if this is a practical solution for your situation.

Keep in mind that water pressure can also vary depending on the time of day and usage patterns in your neighborhood. Peak demand periods can cause pressure fluctuations due to increased strain on the water supply.

By understanding the key factors that contribute to water pressure, you are better equipped to identify and address any issues you may encounter with low pressure in your home.

Causes of Low Water Pressure

Clogged Pipes and Fixtures

Clogged pipes and fixtures can significantly reduce your water pressure. Sediment, mineral deposits, and other debris tend to accumulate in the pipes, especially when hard water is involved. These obstructions restrict the flow of water, causing less pressure at your fixtures. Regularly clean your fixtures, such as showerheads and faucets, to remove buildup and maintain water pressure.

Leaks and Damaged Pipes

Leaks in your plumbing system can reduce water pressure by diverting water flow away from its intended destination. Damaged pipes, whether from corrosion, freezing, or physical trauma, can lead to leaks or complete pipe failure. Periodically inspect your plumbing to identify and address leaks or damage. Copper pipes are generally more resistant to corrosion, making them a popular choice for more durable plumbing.

Pressure Reducing Valves

Pressure reducing valves (PRVs) are installed in some homes to regulate water pressure from the municipal water system. If a PRV is set too low or is malfunctioning, it can lead to lower water pressure inside your home. Check the PRV setting to ensure it is configured for an appropriate pressure level, usually between 40-60 psi.

Closed or Partially Closed Water Valves

Closed or partially closed water valves can significantly affect water pressure. Be sure to check the main shut-off valve near the water meter to ensure it is entirely open. Also, verify that any other water valves within your plumbing system are open and functioning correctly.

Water Softeners

Water softeners that remove hard minerals from your water supply can sometimes contribute to low water pressure. Over time, water softeners can become clogged with sediment, impeding water flow and lowering pressure. Regular maintenance, including flushing the system and cleaning the resin bed, can keep your water softener operating efficiently and maintain water pressure.

Municipal Water System

Low water pressure might not necessarily be an issue with your home’s plumbing but could be due to the municipal water system. The city may be delivering water at a low pressure or experiencing a reduced capacity due to a break in the main water line. If you have ruled out other causes of low water pressure in your home, contact your local water utility to inquire about any potential issues within the municipal system.

Testing Your Water Pressure

Using a Pressure Gauge

To test your home’s water pressure, you’ll need a pressure gauge. You can purchase a water pressure test gauge online or at a local hardware store. Attach the pressure gauge to an outside water spigot or garden hose. Turn on the water and take note of the instant reading on the gauge. A reading of 45 to 60 pounds per square inch (PSI) indicates that your water pressure is at an ideal level. Make sure to fully open the shutoff valves near the water meter for optimal results.

Performing Simple Tests

If you don’t have a pressure gauge, you can still perform simple tests to check your water pressure. Try turning on multiple faucets at once and observe the water flow. If the water pressure decreases significantly when multiple faucets are turned on, this may indicate low water pressure. Additionally, you can check with your neighbors to see if they are experiencing similar issues with their water pressure. If they are, the problem could be with the city’s water distribution system, and you should contact your local municipality.

Remember to use a water pressure test gauge for a more accurate measurement of your home’s water pressure. By performing these tests, you will gain a better understanding of whether you need to increase your water pressure or not.

How to Increase Water Pressure

Clean and Replace Clogged Fixtures

Over time, your faucets and showerheads can become clogged with mineral deposits, reducing the water pressure in your home. To clean them, remove the shower head or faucet aerator and soak them in a mixture of white vinegar and water for a few hours. If the fixture is too clogged or damaged, consider replacing it with a new one that has a higher flow rate.

Repair or Replace Damaged Pipes

Damaged or corroded pipes can restrict water flow and lead to low water pressure. Inspect your plumbing for any visible damage or leaks. If you find any issues, consider calling a professional plumber to repair or replace the damaged pipes. Pay particular attention to older copper or plastic water main connections, as they can be more susceptible to damage over time.

Adjust or Replace Pressure Reducing Valves

Pressure reducing valves (PRVs) are installed in some homes to lower the water pressure coming from the city supply. If your PRV is set too low, it might be causing low water pressure in your home. Locate your PRV (usually located near the water meter) and try adjusting the adjustment screw to increase water pressure. If the valve is old and not functioning properly, you might need to replace it.

Open Water Valves Fully

Check all the water supply valves in your home, including the main water valve and those connected to individual appliances like your washing machine and dishwasher. Ensure that these valves are fully open to allow maximum water flow. If you find closed water valves or partially open ones, open them completely to improve the water pressure in your home.

Upgrade Your Water Softener

A water softener can help reduce the build-up of minerals in your pipes, but an old or poorly functioning unit might negatively impact your water pressure. Check if your water softener is working properly. If it’s older or not functioning effectively, consider upgrading to a new model that is better suited to handle the demands of your appliances and plumbing.
