Is the bathtub spigot leaking from behind when the water is turned on? This can cause all kinds of problems some of which you can see others that you may not notice until it is too late. If it is leaking from behind the spigot it can run down the wall behind the tub creating royal water damage problems. Spigots are relatively easy to replace and are also inexpensive. The bathtub spigot can be replaced with little knowledge of plumbing and can save hundreds of dollars in repairs.
Here are the basic tools needed for replacement: Allen wrench, Channel Lock pliers large enough to go around the spigot and a tube of caulking.
Step 1: Look beneath the spigot to see if it has an Allen Screw or simply unscrews from the pipe. If there is an Allen Screw it will be recessed toward the back of the spigot. After finding the proper wrench size insert it and turn it counter clockwise. This may take a few minutes as these screws are usually hard to turn and you are feeling your way through.
Note: If the spigot is an Allen Wrench style then make sure the screw is all the way out before removing the spigot. If it is not all the way out when removing the spigot it could strip the copper pipe that it is attached to. This will cause more problems. Take the extra few minutes to do it right.
Step 2: After removing the screw the spigot should pull off. This can be done by twisting it clockwise then counter clockwise until it is released. The pliers can be used to assist the turning.
If the spigot does not have an Allen Screw visible then it should unscrew. This can be done by turning the spigot counter clockwise with pliers.
Step 3: After the spigot is removed be sure and put the same depth and style spigot back on. If it screws on then put that kind back and if it is the Allen Wrench style put that one back on.
Note: If the old spigot has a shower pop up attached make sure the new one does as well.
Step 4: After the installation is complete be sure to check your work. Turn the water supply on and make sure there is no water coming from the back of the new spigot. The job should now be complete caulk around the new spigot if desired.
Plumbing is probably one of the hardest jobs to do. There are so many plumbing parts and there is nothing is standard.
