DIY steps
- Shut off the water supply to the tub by locating the shut-off valves and turning them clockwise. Open the tub faucet to drain the water from the pipes.
- Put on safety goggles and gloves, then identify the spout type. For a threaded spout, turn it counterclockwise by hand or with a protected wrench; for a slip-fit spout, loosen its underside set screw with an Allen wrench and slide it straight off. Do not combine these procedures.
- Carefully remove the old spout using the procedure for its type. Inspect the pipe or stub-out for damage and mineral buildup.
- For a threaded replacement, clean the threads and apply plumber's tape only if the spout manufacturer specifies it. For a slip-fit replacement, clean the smooth pipe and use no thread tape.
- Install the new spout using the procedure for its type: hand-thread a threaded spout without cross-threading, or slide on a slip-fit spout and tighten only its set screw. Do not use a wrench to tighten a slip-fit spout.
- Turn the water supply back on and check for leaks around the new spout. Run some water through the faucet to ensure the spout is functioning properly.
- Clean up any mess or debris from the repair, and dispose of the old tub spout.
