Addressing Corroded Wall Seat


Corroded wall seats can be a persistent headache for homeowners, causing leaks, reduced water flow, and potential water quality issues. Fortunately, addressing this issue doesn’t have to be complicated. In this blog, we’ll provide you with a comprehensive guide on how to effectively address corroded wall seats in your plumbing system, ensuring your faucets and valves function optimally and your home remains free from water damage.

1. Identifying Corroded Wall Seats

Before you address the issue, it’s essential to recognize the signs of corroded wall seats. Look for rust, pitting, or visible damage on the inner components of your faucets or shower valves.

2. Gather Necessary Tools

To address corroded wall seats, you’ll need a few tools:

  • Adjustable Wrench: Used for removing faucet handles and fixtures.
  • Plumber’s Tape: Helps create a watertight seal during reassembly.
  • Replacement Parts: New wall seats, faucet washers, and other components as needed.

3. Step-by-Step Approach

Step 1: Turn Off Water Supply

Before you begin any work, turn off the water supply to the affected faucet or shower valve. This prevents water from gushing out while you work.

Step 2: Disassemble the Faucet

  • Remove the faucet handle using an adjustable wrench or screwdriver, depending on the type of handle.
  • Unscrew the packing nut to access the stem assembly.
  • Gently remove the stem assembly.

Step 3: Remove the Corroded Wall Seat

  • Locate the wall seat inside the faucet body.
  • Use a suitable tool, like a seat wrench, to carefully remove the corroded wall seat.

Step 4: Clean and Inspect

  • Thoroughly clean the faucet body to remove any mineral deposits or debris.
  • Inspect the faucet body for signs of damage or pitting. If necessary, consider replacing the entire fixture.

Step 5: Install the New Wall Seat

  • Apply plumber’s tape to the threads of the new wall seat to ensure a watertight seal.
  • Carefully insert the new wall seat into the faucet body, ensuring it’s properly aligned.

Step 6: Reassemble the Faucet

  • Reattach the stem assembly and packing nut.
  • Tighten the packing nut gently to avoid overtightening.
  • Reattach the faucet handle and secure it in place.

Step 7: Test and Monitor

  • Turn on the water supply and test the faucet for leaks.
  • Monitor the faucet over the next few days to ensure that the issue has been successfully addressed.

4. When to Seek Professional Help

If you’re uncomfortable performing these steps or if the corrosion is severe, it’s best to consult a professional plumber. They have the expertise and tools to handle the situation safely and effectively.


Addressing corroded wall seats might seem like a daunting task, but with the right tools and a step-by-step approach, you can restore the functionality of your faucets and shower valves. By taking proactive measures to tackle this issue, homeowners can prevent leaks, improve water flow, and ensure the longevity of their plumbing fixtures. Whether you choose to tackle the task yourself or seek professional assistance, addressing corroded wall seats is a crucial step towards maintaining a healthy and functional plumbing system.
