Have you often been woken up by the sound of your leaky shower faucet? Have you grunted in disgust and shut down the water supply to stop the annoying sound? Then decided that you can learn how to repair it yourself and failed miserably at that too? Have you considered replacing it? Relax, it's not as Herculean a task as you thought in your mind just now. Well, a little maybe, but not terribly. If you don't believe it, read the steps below. They might change your mind.
Step # 1
The first thing you need to do is buy the replacement faucet for the one that is already in your bath. How to do that? Well, the best thing to do is take the old faucet to the store and buy another one that matches its size perfectly.
Step # 2
When you get home, the first thing you need to do is shut the water supply. Else, you'll have a whole lot of water flowing out when you remove the old faucet to fix the new one. The next step is to check for the panel at the rear, which will help you access the main faucet. Ideally, there should be a rear access panel in the wall, so as to avoid any major plumbing disasters. So, find it, and remove it.
Step # 3
After removing the access panel, check what type of system your faucet has. It most probably will have a two-valve one. Now what you do is, remove the cap of the valve, so that the handle screw beneath it gets exposed. Remove the handle for this handle screw.
Step # 4
Use a set of strong pliers to extract the nuts that hold the faucet together. Do this slowly, and as you remove each part, keep it in the same order as you remove it. This will make it easier to put the parts back together again.
Step # 5
After the nuts are removed, it will be easy to pull out the faucet stems from the wall. Do this gently, using the appropriate screwdrivers. You don't want to enlarge the hole in the wall. Otherwise, your new faucet might not fit in. If the stem has a retainer clip, then use needle-nose pliers to remove it.
Step # 6
The next step is to fix the new faucet. Take a screwdriver and begin slowly fixing the new faucet stem to the base that you extracted. Fit it perfectly. Then, beginning with the last part that you removed, fix back everything in reverse order. If there are extra spaces in the wall after you have fixed the new faucet (which should not happen if you have bought a new faucet of the same size), you can seal them up with good quality putty. This will prevent any leakage of water.
With those steps you can replace that leaky faucet in your shower enclosure. However, we strongly recommend that you take professional assistance in case you cannot handle it.
