Corroded valve seat


Corroded wall seats might not be the first thing that comes to mind when you think about household maintenance, but they can pose a significant threat to your plumbing system and home. These seemingly inconspicuous components play a crucial role in preventing leaks and ensuring the proper functioning of fixtures like faucets and showerheads. In this blog, we’ll delve into the world of corroded wall seats, exploring what they are, the dangers they pose, and how to address them effectively.

1. What Are Corroded Wall Seats?

Corroded wall seats are metal components found within faucets and showerheads, where the valve stem comes into contact with the fixture’s body. These seats create a seal that prevents water from leaking out when the fixture is turned off. Over time, exposure to water, minerals, and chemicals can cause corrosion on these seats, compromising their ability to create a watertight seal.

2. The Dangers of Corroded Wall Seats

Corroded wall seats can lead to a range of plumbing problems, including:

  • Leaks: The primary risk of corroded wall seats is leaks. When the seat can no longer provide a proper seal, water can escape even when the fixture is turned off. This can result in wasted water, increased water bills, and potential water damage to your home.
  • Low Water Pressure: Corrosion buildup can restrict the flow of water through the fixture, leading to decreased water pressure. This can affect the functionality of faucets and showerheads, making them less efficient and less enjoyable to use.

3. Addressing Corroded Wall Seats

Dealing with corroded wall seats requires a systematic approach:

  • Inspection: Regularly inspect your faucets and showerheads for signs of corrosion. Look for discolored or deteriorating metal surfaces. Early detection can prevent more extensive damage.
  • Cleaning: If you notice minor corrosion, you might be able to clean the affected area using a soft brush, vinegar, and a cloth. Be gentle to avoid further damage.
  • Replacement: In cases of significant corrosion, it’s best to replace the corroded wall seats. This requires disassembling the fixture and installing new, non-corroded seats. If you’re not comfortable with this process, hiring a professional plumber is a wise choice.

4. Preventive Measures

To prevent or minimize corrosion on wall seats:

  • Use a Water Softener: If your water supply is hard water, consider installing a water softener. Hard water contains high levels of minerals that can contribute to corrosion. A water softener can help reduce mineral buildup.
  • Regular Maintenance: Perform routine maintenance on your fixtures, including cleaning and checking for signs of corrosion. This proactive approach can extend the life of your fixtures and prevent more extensive damage.


Corroded wall seats might seem like a small issue, but they can have significant implications for your plumbing system and home. Leaks, low water pressure, and potential water damage are risks associated with corroded wall seats. Regular inspection, cleaning, and timely replacement can help you address this issue effectively and ensure the proper functioning of your faucets and showerheads. By staying vigilant and taking proactive measures, you can maintain a well-functioning plumbing system and a leak-free home.
