Now, install the new spout. For a THREAD-ON spout, wrap the pipe's threads with 2-3 layers of Teflon tape in a clockwise direction (so it doesn't unravel as you tighten). Then, screw the new spout on by hand until it is snug and facing down. If it's not tight when facing down, give it another full turn. For a SLIP-ON spout, check if your new spout comes with a plastic adapter. If so, slide it onto the copper pipe first. Then, slide the new spout over the pipe until it sits flush against the wall. Ensure the set screw hole is facing down. Use your Allen wrench or screwdriver to tighten the set screw until it is snug. Do not overtighten, as this can dent the copper pipe.
You're viewing a step from: How to Replace a Leaky Bathtub Spout (Thread-on vs. Slip-on)
This guide provides comprehensive instructions for replacing a leaky bathtub spout. The process involves identifying the spout type (thread-on vs. slip-on), carefully removing the old fixture, cleaning and preparing the wall pipe, and correctly installing the new spout to ensure a watertight, leak-free seal.
Frequently Asked Questions
What is the difference between a thread-on and slip-on bathtub spout?
A thread-on spout screws directly onto a threaded pipe nipple coming from the wall. A slip-on spout slides over a copper pipe and is secured with a set screw underneath. Check your existing spout type before buying a replacement.
How do I know if my bathtub spout is leaking from the diverter or the connection?
If water drips from the spout when the shower is running, the diverter is failing. If water leaks around where the spout meets the wall, the connection or seal needs attention. Both issues require removing the spout.
What tools do I need to replace a bathtub spout?
For most spout replacements, you will need a hex key or Allen wrench (for slip-on types), pipe wrench or adjustable pliers (for thread-on types), plumbers tape, and silicone caulk for sealing.
Can I replace a bathtub spout myself without calling a plumber?
Yes, this is typically a DIY-friendly project that takes about 30 minutes. The key is identifying your spout type first and having the right replacement part.
