Install Pipes Under Bathroom Sink: A Step-by-Step Guide

Installing pipes under a bathroom sink may seem daunting, but with the right information and a bit of preparation, it's a task that can be completed with ease. Whether you're a seasoned DIYer or a novice, following this comprehensive guide will empower you to tackle this plumbing project confidently.

Gather Materials and Tools:

P-trap
Supply lines (hot and cold)
Faucet
Pipe wrench or adjustable wrench
Slip joint pliers
Teflon tape
Basin wrench
Level
Plumber's putty

Step 1: Disassemble the Existing Setup:

Before you begin, turn off the water supply to the sink. Use a basin wrench to loosen and remove the nuts holding the faucet. Next, detach the P-trap by loosening the slip nuts on either side. Drain any remaining water from the trap.

Step 2: Install the P-trap:

Position the new P-trap under the sink. Ensure that the curved portion of the trap faces down. Tighten the slip nuts on both sides of the trap using slip joint pliers.

Step 3: Connect the Supply Lines:

Apply Teflon tape to the threaded ends of the supply lines. Connect the hot water supply line to the faucet's hot water inlet and the cold water supply line to the cold water inlet. Tighten the connections using a pipe wrench or adjustable wrench.

Step 4: Install the Faucet:

Place a bead of plumber's putty around the rim of the faucet base. Insert the faucet into the sink's hole and tighten the nuts underneath using a basin wrench. Use a level to ensure that the faucet is installed evenly.

Step 5: Test the Installation:

Turn on the water supply and check for any leaks. Inspect the connections under the sink and around the faucet base. If there are leaks, tighten the connections or apply more Teflon tape as needed.

Congratulations!
