Galvanized pipes are common in many older homes and buildings, and they can last for many years if they are cared for properly. Unfortunately, galvanized pipes are prone to rust, which can cause them to leak. If you have a galvanized water pipe that is leaking at the threads, you may need to repair it. Here are some steps you can take to repair a leaking galvanized water pipe at the threads.
Tools You Need To Repair a Leaking Galvanized Water Pipe at the Threads
Before you begin the repair process, you will need to gather the right tools for the job. These include:
- Channel-type pliers
- Pipe wrench
- Teflon tape
- Thread sealant
Steps to Repair a Leaking Galvanized Water Pipe at the Threads
Once you have all the tools you need, you can begin the repair process. Here are the steps you need to take:
- Turn off the water supply to the pipe. This is an important step, as you do not want to be dealing with a flooded basement or other area if the pipe leaks more than you expect.
- Use the channel-type pliers to loosen the nut at the end of the pipe. The nut is likely to be very tight, so use the pliers to loosen it.
- Once the nut is loose, use the pipe wrench to unscrew the pipe from the fitting. If the pipe is stuck, use a bit of penetrating oil to help loosen it.
- Clean the threads on the pipe and the fitting. Use a wire brush to remove any rust or debris that may be present.
- Apply a few wraps of Teflon tape to the threads of the pipe. This will help provide a watertight seal when the pipe is reattached.
- Apply a thread sealant to the threads of the fitting. This will help ensure that the connection is watertight.
- Reattach the pipe to the fitting, using the pipe wrench to tighten the nut. Once the nut is tight, turn the water supply back on and check for any leaks.
