3 Handle Bathtub Faucet Replacement

3-Handle Bathtub Faucet Replacement: A Comprehensive Guide

Replacing a 3-handle bathtub faucet may seem daunting, but it can be accomplished with the right tools and a bit of know-how. This guide will walk you through the essential aspects of this task, ensuring a successful and leak-free installation.

Tools and Materials Required

Adjustable wrench
Allen wrench (if applicable)
Phillips head screwdriver
Work gloves
New 3-handle bathtub faucet
Plumber's putty
Teflon tape
Bucket or bowl

Step 1: Prepare the Work Area

Turn off the water supply lines beneath the sink or behind the bathtub access panel. Open the bathtub faucet to release any remaining water. Wear gloves to protect your hands from water and sharp edges.

Step 2: Disconnect the Old Faucet

Using an adjustable wrench, carefully loosen the nuts that connect the water supply lines to the old faucet. Disconnect the lines and allow the remaining water to drain into a bucket. Remove the handle screws with a Phillips head screwdriver and lift the handles off.

Step 3: Remove the Cartridge or Stems

Most 3-handle faucets have cartridges or stems that control the water flow. If you have cartridges, use an adjustable wrench or cartridge puller to remove them. If you have stems, use an Allen wrench to loosen and remove the packing nuts, then pull the stems out.

Step 4: Install the New Cartridge or Stems

Apply a thin bead of plumber's putty around the base of the new cartridge or stem. Insert it into place and hand-tighten it as much as possible. Use the adjustable wrench to fully tighten it, but do not overtighten.

Step 5: Connect the Faucet Handles

Slide the handles onto the cartridges or stems and secure them with the handle screws. Snug them up with a screwdriver, but again, avoid overtightening.

Step 6: Connect the Water Supply Lines

Apply Teflon tape to the threads of the water supply lines and screw them back onto the faucet. Use an adjustable wrench to hand-tighten the nuts securely. Open the water supply lines and check for leaks.

Step 7: Finalize the Installation

If there are no leaks, you can complete the installation. Wipe away any excess plumber's putty or water and enjoy your newly replaced 3-handle bathtub faucet.
