If you have a wall mounted tub faucet, one of the problems that you could face is the screws coming loose, or the parts inside the tub working their way free of the surroundings. If you experience this problem, then you may need to tighten this up yourself. The other option, of course, is to call in a plumber, but you would not want to do this unless you are feeling very free with your money. Getting the best out of your plumbing sometimes means working to fix a problem yourself. So long as you have some basic home improvements skills, and a spare hour or two, then you should be able to tighten your wall mounted tub faucet yourself.
Step 1 - Turning off the Water
In order to start working on your faucet, you will need to make sure that the water is turned off in the bathroom. You can do this in one of two ways. You can turn off the upstairs water supply by turning the knob which is usually under the sink or behind the toilet. This knob controls the flow of water upstairs, while allowing the downstairs to work just as well. If you are not sure that you are secure with just the upstairs water turned off, then you can go downstairs to the main water supply valve and turn this off. You may need a wrench to turn the valve fully in the right direction. Run the water from your taps until it is completely gone.
Step 2 - Screw the Faucet
You will now be able to screw the wall-mounted tub faucet back into position. Find the screw which secures your faucet onto the tub mount and place your handle on top of the faucet while you unscrew the tub. Take out the screw and check it for signs of cracking or corrosion which could be the cause of your tub faucet freeing itself from the wall. In particular, check the ball mount for signs of scratching, which will indicate damage to the screw. If you are happy that it is in good condition, screw the faucet as tightly as possible into position. You are now ready to proceed.
Step 3 - Finishing up
When you have screwed the wall mounted tub faucet into position as tightly as you can, then you should check this by moving the faucet left and then right. If your faucet is still wobbling, then you may need to lay a little bit of caulking around the edge of the faucet, in order to keep it in one place. Take a putty knife and add a little layer of caulking to the edge. Place the knife against the side of the faucet and apply this layer evenly until you are sure that the caulking has gone into the bottom of the faucet. Press the faucet down, and then screw as tightly as you can.
