How to Replace a Tub Spout How to Replace a Tub Spout

What You'll Need
Hexwrench
Pipe nipple
New spout (either screw-on, or slip-on)
Tube cutter
Large flat head screwdriver
Duct tape

There are a number of ways that a tub spout can get destroyed. Behind your bathtub faucet is a diverter. This diverter can be worn and thus it no longer blocks water from flowing out of the faucet to be diverted into the shower head. Another way that your spout can be destroyed is that the threads inside the spout can crack or corrode. These threads are located where the spout screws onto the pipe. If this happens, water might trickle along the pipe and get inside the wall. A third way that the spout can be destroyed is that its finish can corrode or flake off. If any of these things happen, you should replace the faucet.

Step 1 - Decide What Kind of Spout You Need

A new spout only costs 10 to 20 dollars. But first, you must decide what kind of spout you will need. Look under the spout.  You might need to use a screwdriver. If you see a screwset, you will need to buy a “slip-on” spout. It does not have a setscrew, you will want to purchase a screw-on spout.

Step 2 - Replace the Spout

Replacing a slip-on spout is very straightforward. Loosen up the setscrew. You will probably need a hex wrench for this. Alternatively, you might need to use a big screwdriver. Hold the screwdriver in one hand and the spout in the other. Now twist the spout counter-clockwise. This will loosen and the spout and it should now be easy for you to remove. If you plan on reusing the spout, protect it with a couple of wraps of duct tape where the wrench will be placed. Now pull the spout off the protruding copper pipe. Twist the spout while you are pulling. Make sure that you do not loose any pipe connections that might be inside the wall. Slide on the sprout. Now, tighten the setscrew.

If the spout it a screw-on, twist the old spout counterclockwise and remove. the pipe that protrudes from the wall might be copper with threaded fitting. If it is, use a tubing cutter to cut off the fitting. Then install the new spout. If this protruding pipe is made out of steal, tube cutters will not do the job.You will need to buy a new screw-on spout. The new spout should ft into the old pipe perfectly. If the pipe protrudes too far, or not far enough you will have to remove the old pipe. This is also the case if the new spout does not fit perfectly into the old pipe.

Step 3 - Replace the Old Pipe If Necessary

Pipe “nipples” - meaning short sections of threaded pipe - are often available in 1-inch increments.They usually cost less than $2 dollars each.
