How To Repair An Old Compression Faucet

As a homeowner, you want to make sure all of your plumbing is working properly. A compression faucet is a common type of faucet found in many homes, but it can wear out over time and need repairs.

If you’re looking to repair an old compression faucet, you’ve come to the right place. This article will walk you through the steps you need to take to identify the problem, gather the necessary supplies, and repair your compression faucet.

Let’s get started!

Identifying the Problem

You must identify the issue before you can move on to the next step of addressing the plumbing fixture.

Start by checking for clogged pipes. If you have clogged pipes, you need to find the source and clear the blockage.

If you have a water leak, you’ll need to determine if the issue is caused by a faulty seal, an issue with the valve, or a crack in the fixture.

You may need to disassemble the fixture to verify the source of the leak. Once you’ve identified the issue with your compression faucet, you can move on to the necessary repairs.

Gathering the Necessary Supplies

Gather the items you’ll need quickly and easily – don’t let a lack of supplies hold you back from completing the job!

You’ll need some basic installing tools, such as a wrench and a screwdriver, for tightening or loosening the faucet parts. You’ll also need to recognize the parts of the faucet, like the O-ring, washer, or valve seat. Additionally, you may need other items such as a replacement valve stem or a tube of plumbing compound.

You may also need a few other items to help make the job easier, such as:

  • Protective Gear:

  • Safety goggles

  • Glove

  • Cleaning Supplies:

  • Mild cleaner

  • Rag

  • Miscellaneous Supplies:

  • Adjustable pliers

  • Pipe wrench

  • Teflon tape

Replacing the Faucet Washer

To begin the process of replacing your faucet’s washer, you’ll need to locate the washer and unscrew it from the faucet fixture.

It’s important to examine the seals around the fixture, as well as the gasket, to make sure they are properly installed.

Once you’ve done this, you can begin the process of unscrewing the washer. Carefully use a wrench to loosen the washer and then remove it from the fixture.

Once the washer is off, you’ll need to find a replacement. Match up the size and shape of the old washer to the new one and be sure the new washer is the same size and shape as the old one.

Once you have found the right washer, you can install it by screwing it into the faucet fixture. Make sure it is securely in place before you finish the job.

Replacing the Faucet Seat

Tighten your grip and take a closer look at the faucet fixture, as you’ll need to unscrew the seat to get the job done.

Installing a replacement seat requires inspecting the existing one for signs of damage. If the seat is chipped, cracked, or otherwise damaged, you’ll need to purchase a new seat.

Start by using a basin wrench to loosen the nuts on either side of the valve stem. Once the nuts are loose, you can unscrew the seat and remove it.

Next, take the new seat and apply a thin layer of plumber’s grease or lubricant onto the threads. This will help ensure a tight seal and prevent any leaks.

Once the new seat is in place, tighten the nuts with your wrench. Make sure the seat is secure and flush with the faucet before you turn the water back on.

You can now turn the handle to check for any leaks or problems.

Testing the Repair

Now that the new seat is installed, take a moment to assess your work and make sure you won’t be left with any unwelcome surprises.

Start by assessing the damage that prompted you to replace the seat in the first place. Inspect the area for any signs of corrosion or other damage to the valve body, as well as any issues with the new seat’s fit.

Also consider the valving options you have available to you. If you have any doubts about the success of the repair, don’t hesitate to contact a professional for assistance.

Next, test the faucet to make sure that the repair has been successful. Turn on the water supply to the faucet and open the faucet to its fullest.

Let the water run for a few minutes and check for any signs of leaks or drips. If everything looks good, turn off the water supply and check the handle and knob operation.

Make sure they move smoothly and that they can be easily operated. If everything is working correctly, you can be satisfied that your repair has been successful.

Tightening the Compression Nut

After fitting the new seat, it’s time to secure it in place by tightening the compression nut. Doing this step properly is important for preventative maintenance and to help prevent further deterioration of the faucet.

To begin, make sure the nut is snug but not overly tight. If it’s too tight, it can cause damage to the faucet and lead to leaking. Use a wrench to tighten the nut in a clockwise direction until it’s secure.

Make sure the connection between the faucet and the water supply line is sealed and secure. If it’s not, you may need to use a pipe sealant to help create a watertight connection.

Once the nut is tightened, turn on the water valve to check for leaks. If the faucet is still leaking, you may need to tighten the nut a bit more. Repeat this process until the faucet is no longer leaking and then you can be confident your repair is complete.

Troubleshooting Common Issues

If you’re experiencing any issues with your new faucet, troubleshooting common issues is a great way to get it back up and running. It’s important to assess any damage to the faucet, evaluate your options, and take the necessary steps to correct the problem.

Here are some tips to help you troubleshoot common issues:

  • Check the valve seat and the valve stem for corrosion or damage.
  • Make sure all connections are tight and secure.
  • Replace any damaged parts or faulty valves.
  • Clean the valve seat and the valve stem to remove any debris or build-up.
