Replacing Bathroom Sink Water Supply Lines

Replacing the water supply lines to your bathroom sink is a relatively simple task that can be completed in a few hours. By following these steps, you can ensure that your sink is properly connected and free of leaks.

Step 1: Gather Your Materials

Before you begin, you will need to gather the following materials:

Two new water supply lines (one for hot water and one for cold water)
A wrench
A pair of pliers
A bucket
A rag

Step 2: Turn Off the Water Supply

Once you have gathered your materials, you need to turn off the water supply to your sink. To do this, locate the shutoff valves beneath the sink and turn them clockwise until they are fully closed.

Step 3: Disconnect the Old Water Supply Lines

Once the water supply is turned off, you can disconnect the old water supply lines. To do this, use a wrench to loosen the nuts that connect the lines to the sink and the shutoff valves. Once the nuts are loose, you can use your pliers to remove the lines.

Step 4: Install the New Water Supply Lines

Now you can install the new water supply lines. To do this, first wrap a few wraps of Teflon tape around the threads of the new lines. Then, screw the new lines into the shutoff valves and the sink by hand. Once the lines are hand-tight, use your wrench to tighten them further. Be careful not to overtighten the lines, as this could damage them.

Step 5: Turn On the Water Supply

Once the new water supply lines are installed, you can turn on the water supply. To do this, simply turn the shutoff valves counterclockwise until they are fully open. Check for leaks around the connections. If you see any leaks, tighten the nuts until the leaks stop.

Step 6: Clean Up

Once the water supply is turned on and there are no leaks, you can clean up. Use a rag to wipe away any water that may have spilled during the repair. You can also use a bucket to catch any water that drips from the sink while you are working.

Conclusion

Replacing the water supply lines to your bathroom sink is a simple task that can be completed in a few hours. By following these steps, you can ensure that your sink is properly connected and free of leaks.
