Replacing shower wall taps may seem like a daunting task, but with the right guidance and a few simple tools, it's a manageable DIY project that can save you the cost of hiring a professional. Whether your taps are leaking, looking dated, or simply not functioning as they should, this comprehensive guide will walk you through the process step by step.
Before you begin, it's crucial to understand that there are two main types of shower taps: those with a single lever for temperature and flow control, and those with separate hot and cold taps. This guide will cover both types, ensuring you have all the information you need to tackle your specific situation.
Preparation and Safety Measures
Before you start, ensure you have all the necessary tools and materials. You'll typically need an adjustable wrench, a flathead screwdriver, pliers, a basin wrench (for hard-to-reach nuts), Teflon tape, and, of course, your new taps. It's also a good idea to have a towel or bucket on hand to catch any water that may leak out during the process.
Safety is paramount when working with water and electrical components. Always turn off the water supply at the main valve before starting any work. If your shower is an electric shower, ensure the power is also turned off at the mains. Use a voltage tester to confirm that no power is flowing before proceeding.
Identifying Your Tap Type
As mentioned earlier, there are two main types of shower taps. To identify yours, look at the handles. If there's one handle that controls both temperature and flow, you have a single-lever mixer tap. If there are two separate handles, one for hot and one for cold, you have separate tap valves.
It's essential to identify your tap type to ensure you purchase the correct replacement. While the process for replacing both types is similar, there are some slight differences that could trip up an unsuspecting DIYer.
Gathering Your Tools and Materials
Once you've identified your tap type, make a list of the tools and materials you'll need. For most taps, you'll need an adjustable wrench, a flathead screwdriver, pliers, and a basin wrench. You'll also need Teflon tape to create a watertight seal on the threads of the new taps. If your taps are made of brass, you may also need some brass lubricant to make removal easier.
Don't forget to purchase your new taps! Make sure they're compatible with your existing plumbing setup and that they match the style and finish of your bathroom. It's also a good idea to have a towel or bucket on hand to catch any water that may leak out during the process.
Removing the Old Taps
Now that you're prepared, it's time to remove the old taps. The first step is to turn off the water supply at the main valve. Once the water is off, open the taps to relieve any remaining pressure in the pipes.
Next, you'll need to remove the cover plates that hide the nuts securing the taps to the wall. These can usually be pried off with a flathead screwdriver. Once the cover plates are off, you should see the nuts that secure the taps. These can be quite tight, so you may need to use an adjustable wrench or a basin wrench to loosen them.
Removing the Tap Handles
Before you can remove the taps, you'll need to take off the handles. For single-lever mixer taps, this usually involves unscrewing a set screw on the side of the handle using a flathead screwdriver. For separate tap valves, you may need to use a special tool to remove the handles, as they're often secured with a grub screw hidden beneath a decorative cap.
Once the handles are off, you should be able to see the spindle that connects the handle to the tap mechanism. This can usually be pulled out with pliers. If it's stuck, you may need to use some penetrating oil to loosen it up.
Removing the Tap Body
With the handles and spindles removed, you should now be able to see the tap body itself. This is the part that connects to the water supply pipes. To remove it, you'll need to unscrew the nuts that secure it to the wall. These can be quite tight, so you may need to use an adjustable wrench or a basin wrench.
Once the nuts are loose, you should be able to pull the tap body out of the wall. If it's stuck, you may need to use some penetrating oil to loosen it up. With the tap body removed, you should now have a clear view of the water supply pipes.
Installing the New Taps
With the old taps removed, it's time to install the new ones. The process is essentially the reverse of removing the old taps, so it's a good idea to keep the old parts handy in case you need to refer to them.
Before you start, make sure the new taps are the same size and type as the old ones. If they're not, you may need to make some adjustments to the plumbing, which could involve cutting into the wall and is best left to a professional.
Preparing the New Taps
Before you install the new taps, it's a good idea to prepare them by wrapping the threads with Teflon tape. This will create a watertight seal and help prevent leaks. If your taps are made of brass, you may also want to lubricate the threads with some brass lubricant to make installation easier.
Once the threads are prepared, it's time to install the new taps. Start by inserting the tap body into the wall, making sure it's properly aligned with the water supply pipes. If the tap body is too long, you may need to shorten it using a hacksaw. Be careful not to cut into the water supply pipes, as this could cause leaks.
Securing the New Taps
With the tap body in place, it's time to secure it to the wall. Start by screwing on the nuts that came with the new taps. Tighten them by hand as much as you can, then use an adjustable wrench to give them a final tug. Be careful not to overtighten, as this could strip the threads or damage the tap.
Once the nuts are secure, it's time to install the new handles. For single-lever mixer taps, this usually involves pushing the spindle into place and screwing on the handle using a set screw. For separate tap valves, you may need to use a special tool to secure the handles, as they're often secured with a grub screw hidden beneath a decorative cap.
Testing the New Taps
With the new taps installed, it's time to test them to make sure everything is working correctly. Start by turning the water supply back on at the main valve. Let the water run for a few seconds to clear any debris from the pipes, then turn the taps on and off a few times to make sure they're working correctly.
Check for any leaks around the taps and under the sink. If there are any leaks, you may need to tighten the nuts or wrap the threads with more Teflon tape. If the leaks persist, you may need to call a professional plumber.
Finishing Touches
With the taps tested and working correctly, it's time to put the finishing touches on the job. Replace the cover plates that hide the nuts securing the taps to the wall. If necessary, use some silicone sealant to create a watertight seal around the taps.
Finally, give your bathroom a quick clean to remove any dirt or debris from the installation process. With the new taps installed and working correctly, your bathroom should now be looking and functioning better than ever.
