## How to Remove Pipes Under Kitchen Sink
Removing pipes under the kitchen sink can be a daunting task, but it’s actually quite simple with the right tools and a little know-how. Here’s a step-by-step guide on how to do it safely and effectively:
### Tools and Materials You’ll Need:
– Adjustable wrench
– Basin wrench
– Channel-lock pliers
– Hacksaw
– Bucket
– Towels
– Safety glasses
### Safety Precautions:
– Always wear safety glasses when working with plumbing.
– Turn off the water supply to the sink before starting any work.
– Open the faucet to release any remaining water in the pipes.
– Place a bucket under the pipes to catch any water that may leak out.
### Step-by-Step Instructions:
#### 1. Disconnect the Water Supply Lines:
– Locate the water supply valves under the sink and turn them off clockwise.
– Use an adjustable wrench to loosen the nuts connecting the flexible water supply lines to the sink faucet.
– If the nuts are too tight, use a basin wrench to provide extra leverage.
#### 2. Remove the Drain Trap:
– Place a bucket under the drain trap, which is the U-shaped pipe that connects the sink to the main drain.
– Loosen the slip nuts on both ends of the drain trap using channel-lock pliers.
– Carefully remove the drain trap and discard it.
#### 3. Cut the Pipes:
– Measure and mark the pipes where you need to cut them.
– Use a hacksaw to cut the pipes perpendicular to their length.
– Deburr the cut edges of the pipes using a file or sandpaper.
#### 4. Install New Pipes:
– Apply pipe dope to the threads of the new pipes.
– Hand-tighten the new pipes into the fittings.
– Use an adjustable wrench or basin wrench to further tighten the connections.
#### 5. Reconnect the Water Supply Lines:
– Screw the flexible water supply lines onto the sink faucet hand-tight.
– Use an adjustable wrench to further tighten the connections.
#### 6. Reconnect the Drain Trap:
– Slide the new drain trap onto the sink drainpipe.
– Tighten the slip nuts on both ends of the drain trap using channel-lock pliers.
#### 7. Turn on the Water Supply and Check for Leaks:
– Slowly turn on the water supply valves.
– Inspect all connections for leaks.
– If you find any leaks, tighten the connections further or replace the faulty parts.
### Troubleshooting Common Problems:
– **Leaking connections:** Tighten the connections until the leak stops. If the leak persists, replace the washers or gaskets.
– **Clogged drain:** Remove the drain trap and clean out any debris.
– **Broken pipes:** Cut out the damaged section and replace it with new pipe.
– **Water hammer:** Install water hammer arrestors on the water supply lines to prevent water hammer (banging noise).
### Tips for Success:
– Take pictures of the plumbing before you start disassembling it, so you can remember how it goes back together.
– Use pipe dope on all threaded connections to prevent leaks.
– Tighten all connections securely, but avoid overtightening as it can damage the parts.
– If you’re not comfortable working with plumbing, call a licensed plumber for assistance.
By following these steps and taking the necessary precautions, you can safely and effectively remove pipes under your kitchen sink yourself. Happy plumbing!
