How to Replace a Sink Trap in 10 Minutes (Step-by-Step Guide)

A clogged sink trap can cause a lot of headaches, from slow-draining water to unpleasant odors. If you’re facing this issue, replacing the sink trap is a relatively simple and effective solution. This comprehensive guide will walk you through the steps on how to replace sink trap and get your drains flowing smoothly again.

Gather the Necessary Tools

Before you start, make sure you have the following tools on hand:

• Adjustable wrench
• Plumber’s putty
• New sink trap
• Bucket
• Rags
• Screwdriver (optional)

Safety Precautions

• Turn off the water supply to the sink.
• Place a bucket under the sink to catch any water that may leak out.
• Wear gloves to protect your hands.

Remove the Old Sink Trap

1. Locate the trap: The sink trap is usually located under the sink, where the drain pipe connects to the wall.
2. Loosen the nuts: Use an adjustable wrench to loosen the nuts that hold the trap in place. There will be two nuts, one on each side of the trap.
3. Remove the trap: Once the nuts are loose, you can remove the old trap by pulling it straight down.

Clean the Drain Pipe

Once the old trap is removed, use a rag to clean the drain pipe. Remove any debris or buildup that may have accumulated.

Install the New Sink Trap

1. Apply plumber’s putty: Roll out a small piece of plumber’s putty into a rope and wrap it around the threads of the new trap. This will create a seal and prevent leaks.
2. Hand-tighten the trap: Screw the new trap onto the drain pipe by hand. Tighten it as much as possible.
3. Use an adjustable wrench: Use an adjustable wrench to further tighten the nuts. Do not over-tighten, as this can damage the trap.

Reconnect the Water Supply

1. Turn on the water: Turn the water supply back on and check for leaks.
2. Tighten the nuts: If there are any leaks, use an adjustable wrench to tighten the nuts further.

Test the Sink

Run water through the sink to make sure it is draining properly. If the water is still draining slowly, there may be another issue with the drain line.

Other Tips

• If the nuts are rusted or difficult to remove, you can use a screwdriver to gently tap them loose.
• If you have a double sink, you will need to replace both sink traps.
• If you are replacing the trap on a pedestal sink, you may need to remove the pedestal to access the trap.
• For stubborn clogs, you can try using a drain cleaner or a drain snake.

When to Call a Plumber

While replacing a sink trap is a relatively simple task, there are some situations where it is best to call a plumber:

• If you are not comfortable working with plumbing.
• If the clog is located deep in the drain line.
• If you have a leak that you cannot stop.
