Water discoloration is a common concern for many homeowners, and it can be quite alarming to turn on your faucet only to find discolored water flowing out. While there can be several underlying causes for water discoloration, one frequently overlooked culprit is the pressure tank. In this article, we will explore whether pressure tanks can indeed cause water discoloration and discuss potential remedies to resolve this issue.
Understanding Pressure Tanks
Before delving into the topic, let us briefly understand what pressure tanks are and their role in a residential water system. Pressure tanks are pivotal components of well systems and are responsible for maintaining a steady water pressure throughout the plumbing system. These tanks work alongside pumps to regulate water flow and reduce the frequency of pump cycling.
The Inner Workings of a Pressure Tank
Pressure tanks are typically made of steel or fiberglass and are equipped with a rubber diaphragm or bladder. This diaphragm or bladder divides the tank into two compartments – one for water and the other for air. The air compartment is pressurized using an air compressor, while the water compartment receives water from the well pump. By compressing the air, pressure tanks store potential energy that helps maintain consistent water pressure even when the pump is not actively running.
Water Discoloration: The Possible Connection to Pressure Tanks
Water discoloration can take on various hues, such as brown, rusty, yellow, or even black. While there are several possible causes for water discoloration, including pipe corrosion, municipal supply issues, or sediment buildup, pressure tanks can contribute to this problem as well. Let’s explore how.
1. Corrosion within the Pressure Tank
Over time, corrosion can occur within the pressure tank, especially in steel tanks that lack a protective lining. This corrosion can result from the constant contact between the water and the tank interior. As the tank corrodes, small flakes or rust particles can break off and mix with the water, leading to discoloration when it reaches the faucets.
2. Sediment Buildup
Sediment buildup is another factor that can cause water discoloration linked to pressure tanks. If the water entering the tank contains sediment or debris, some of it can settle at the bottom over time. This sediment can consist of minerals, dirt, or even organic matter. When the water is drawn from the tank, the sediment gets disturbed, leading to discoloration.
Troubleshooting and Remedies
If you suspect that your pressure tank might be causing water discoloration, there are a few steps you can take to troubleshoot the issue and potential remedies to resolve it.
1. Check the Pressure Tank
Start by examining the pressure tank for visible signs of corrosion or damage. If you notice any rusting, flaking, or leaks, it may be time to consider replacing the tank.
2. Flushing the System
Flushing the plumbing system can help remove any sediment or rust particles that may have accumulated. Begin by turning off the power supply to the water pump and closing the main water valve. Open all the faucets in your home, starting from the highest floor and moving downward. Let the water flow for a few minutes until it runs clear. Once the water is clear, close the faucets and turn the power back on.
3. Regular Maintenance
To prevent future water discoloration issues arising from the pressure tank, it is important to conduct regular maintenance. This includes inspecting and cleaning the tank periodically, ensuring the pressure is properly adjusted, and installing a filter or water treatment system if necessary.
While pressure tanks are essential for maintaining a steady water supply, they can potentially contribute to water discoloration issues. The corrosion within the tank and sediment buildup are two common causes for this problem. By understanding the role of pressure tanks and implementing proper troubleshooting and maintenance measures, homeowners can minimize the risk of water discoloration and enjoy clean, fresh water from their faucets.
