How to Replace Shower Taps: A Comprehensive Guide

Replacing your shower taps might seem daunting, but with the right tools and a step-by-step approach, it's a manageable DIY project that can save you money and enhance your bathroom. This comprehensive guide will walk you through the entire process, from assessing your taps to enjoying a refreshed shower experience. Whether you're dealing with a dripping tap, a faulty mixer, or simply want an upgrade, this guide provides the knowledge and confidence to tackle the job successfully. We'll cover everything from identifying your tap type to understanding plumbing basics, ensuring you're well-equipped for a successful installation.

1. Assessing Your Shower Taps and Gathering Supplies

Before you even touch a wrench, take a moment to understand what you're working with. This crucial first step prevents unexpected complications and ensures you have the right materials.

1.1 Identifying Your Tap Type:

There are several types of shower taps, each requiring slightly different approaches to replacement. The most common types include:

• Traditional Two-Handle Taps (Hot and Cold): These have separate taps for hot and cold water.
• Mixer Taps (Single Lever): These use a single lever to control both temperature and water flow.
• Thermostatic Mixer Taps: These maintain a consistent water temperature, regardless of water pressure fluctuations.
• Concealed Shower Valves: The valve mechanism is hidden behind the wall, with only the handles visible. Replacing these is significantly more complex and often requires professional assistance.

1.2 Checking Water Supply:

Before starting any work, turn off the water supply to your shower. This is usually done via isolation valves located under the sink or near the shower. If you can't locate these valves, you may need to turn off the main water supply to your house.

1.3 Gathering Your Tools and Materials:

You'll need the following:

• New Shower Taps: Ensure you purchase taps compatible with your existing plumbing system and desired style. Check the specifications carefully, noting the connection size and type (e.g., 1/2" BSP).
• Adjustable Wrenches: A set of adjustable wrenches in various sizes is essential.
• Basin Wrench: This specialized tool helps access hard-to-reach nuts and bolts under the sink.
• Screwdrivers (Phillips and Flathead): For removing screws and trim plates.
• Plumbing Tape (PTFE Tape): Used to seal pipe threads and prevent leaks.
• Old Rags or Towels: For cleaning up spills and preventing scratches.
• Safety Glasses: Protect your eyes from debris.
• Optional: Penetrating Oil: To loosen stubborn fittings.
• Optional: Pipe Joint Compound: Provides an extra layer of sealant.

2. Removing the Old Shower Taps

This section details the process for removing typical two-handle and mixer taps. Remember, removing concealed valves is a much more advanced task requiring specialized tools and knowledge.

2.1 Two-Handle Taps:

1. Remove the Handles: Look for small screws underneath or on the side of the handles. Unscrew them and carefully remove the handles.
2. Locate and Remove the Index Plates: Once the handles are removed, you'll find index plates (decorative covers) covering the nuts that secure the taps to the pipes. Carefully remove these plates.
3. Unscrew the Nuts: Using appropriate wrenches, carefully unscrew the nuts connecting the taps to the pipes. Penetrating oil may be helpful if the nuts are stuck. Be prepared for some water dripping – this is why turning off the supply is crucial.
4. Disconnect the Taps: Once the nuts are removed, gently pull the taps out. You may need to wiggle them slightly.
5. Remove the Tailpieces: Carefully remove the tailpieces (the short pipes connecting the taps to the water supply pipes).

2.2 Mixer Taps (Single Lever):

1. Remove the Handle: Some mixer taps have a small screw underneath the handle; others require carefully prying it off. Check your tap's instructions if unsure.
2. Locate and Remove the Cartridge: Once the handle is removed, you'll find a cartridge or internal mechanism. This usually requires unscrewing a nut or collar securing the cartridge.
3. Disconnect the Water Supply: After removing the cartridge, disconnect the water supply pipes (similar to the process for two-handle taps).
4. Remove the Tap Body: Remove the main tap body.

3. Installing the New Shower Taps

This process mirrors the removal steps in reverse but with attention to detail and proper sealing.

3.1 Preparing the New Taps:

Before installing the new taps, carefully examine them and ensure all components are present.

3.2 Installing Two-Handle Taps:

1. Connect the Tailpieces: Connect the tailpieces to the new taps and wrap the threads with PTFE tape to create a watertight seal. Ensure the tape is applied neatly and evenly.
2. Install the Taps: Carefully push the new taps into position, aligning them with the water supply pipes.
3. Tighten the Nuts: Tighten the nuts securing the taps, but avoid over-tightening.
4. Replace the Index Plates: Place the index plates back on, ensuring they are properly aligned.
5. Install the Handles: Replace the handles and screws.

3.3 Installing Mixer Taps:

1. Install the Cartridge: Insert the new cartridge into the tap body.
2. Connect the Water Supply: Connect the water supply pipes, ensuring a watertight seal with PTFE tape.
3. Install the Tap Body: Carefully install the tap body.
4. Install the Handle: Replace the handle and secure it tightly.

4. Testing and Finishing Touches

Once the new taps are installed, it's time to test for leaks and ensure everything is functioning correctly.

4.1 Turn on the Water Supply:

Slowly turn on the water supply and check for any leaks around the taps and connections. If you find a leak, carefully tighten the connections. If the leak persists, you may need to redo the PTFE tape application.

4.2 Test the Functionality:

Test both the hot and cold water flow (for two-handle taps) or the temperature and flow control (for mixer taps). Ensure the water pressure is adequate and the taps operate smoothly.

4.3 Clean Up:

Clean up any debris or excess PTFE tape.

5. Troubleshooting and FAQs

Even with careful attention, issues can arise. Here are some common problems and solutions:

Q: The tap is still leaking after installation.

A: Check the PTFE tape application. Insufficient or incorrectly applied tape is a common cause of leaks. You may need to disassemble the connection, remove the old tape, and reapply it correctly. If the problem persists, the tap itself might be faulty.

Q: The tap is difficult to turn.

A: The tap may be over-tightened. Carefully loosen the connections slightly. Lubricating the moving parts with a suitable lubricant might also help.

Q: The water pressure is low.

A: This is not necessarily related to the tap installation. Check your main water supply and other fixtures to rule out a wider pressure problem.

Q: I'm uncomfortable working with plumbing. Should I call a professional?

A: If you're unsure or uncomfortable working with plumbing, it's always best to call a qualified plumber. They have the expertise and tools to handle more complex situations safely and efficiently.
