Removing an Existing Tap

1. Turn Off the Water Supply

The first step in removing an old tap is to ensure that no water is flowing during the process:

• Locate and Close Isolating Valves: Most kitchen sinks have isolating valves located under the sink. These valves control the water flow to the tap. To close them, turn each valve clockwise until it is fully closed. If you’re unsure which valves control the hot and cold water, turning off both ensures that no water will flow from either line.
• Main Stopcock: If your sink does not have isolating valves or if you cannot access them, you will need to turn off the main stopcock. The main stopcock is usually located in your home’s utility room or under the kitchen sink. Turn the stopcock clockwise to shut off the water supply to the entire house.
• Run the Tap: After closing the valves or stopcock, turn on the tap(s) to drain any remaining water in the pipes. This step is essential to avoid spills when disconnecting the tap. Let the water run until it stops, confirming that the flow has ceased. Check any valve at the hot water supply tank if applicable, to ensure that the water is completely off.

2. Prepare the Area

Preparing the area under the sink helps in managing any water that might spill and ensures easy access to the tap components:

• Clear Space Under the Sink: Remove any items stored under the sink to create a clear workspace. This might include cleaning supplies, trash cans, or storage containers. Having a clear area makes it easier to access the tap and work comfortably.
• Lay a Towel and Place a Washing Bowl: Place a towel on the floor beneath the sink to catch any water that may leak during the removal process. Position a washing bowl under the area where you’ll be working to catch any residual water that might spill out when you disconnect the tap.
• Ensure You Have All Required Tools: Gather all necessary tools before starting the removal process. These typically include a basin wrench or back nut box spanner, slip joint pliers, and a cleaning cloth. Having everything at hand will streamline the process and prevent delays.

3. Disconnect the Tap

Disconnecting the tap involves removing the connections that hold it in place:

• Standard Water Pipe Connections: For taps with standard water pipe connections, use an open-ended spanner to loosen the nuts that secure the tap to the pipes. Hold the tap steady with one hand while using the spanner with the other hand to avoid putting undue stress on the pipes. Ensure you have a cloth handy to protect the finish and catch any residual water.
• Flexible Hose Connections: If your tap is connected via flexible hoses, use slip joint pliers to loosen the nuts on the hose connections. Place a cloth over the connection to protect it from scratches and to catch any water that might escape. Once the nuts are loosened, remove the hoses by unscrewing them from the tap.

4. Extract the Existing Tap

Once the water connections are detached, you can proceed with removing the tap itself:

• Loosen and Remove the Nut Securing the Tap: Depending on the type of tap you have, use a basin wrench or a back nut box spanner to loosen the nut that secures the tap to the sink. For pillar or bridge taps, the nut is typically located beneath the sink. For single block or mixer taps, it might be easier to access from above.
• Remove the Tap and Hoses: Once the securing nut is removed, lift the tap out of the sink. Be prepared for some residual water to spill out. Clean the area around the mounting holes with a wet cloth to remove any old sealant or residue. This will prepare the surface for the new tap installation.
• Clean Any Residue: If there is any remaining residue or old sealant around the pipe connections, gently clean it with a cloth. For stubborn residue, you might need a limescale remover or a mild cleaner appropriate for the material of the sink. Ensure the area is dry and clean before proceeding with the new tap installation.

Fitting a New Tap

1. Clean the Mounting Surface

The mounting surface is where the new tap will be installed. Proper preparation of this area is crucial for ensuring a secure and leak-free installation. Start by removing any old sealant or debris from the previous tap:

• Removing Old Sealant: Use a plastic scraper or a utility knife to gently scrape away any old sealant around the mounting holes. Be careful not to scratch or damage the sink surface. Old sealant can prevent the new tap from sitting flush against the sink, leading to leaks.
• Cleaning Residue: Once the old sealant is removed, clean the surface with a damp cloth to remove any remaining particles. For stubborn residues, use a mild cleaner appropriate for the material of your sink (e.g., stainless steel cleaner for stainless sinks, or a general-purpose cleaner for ceramic sinks). If there’s limescale buildup, use a limescale remover according to the product’s instructions. Make sure the surface is completely dry before proceeding to ensure a proper seal.

2. Mount the New Tap

With the mounting surface prepared, proceed to install the new tap. This step involves placing the tap correctly and ensuring it’s securely fastened:

• Apply PTFE Tape: PTFE tape, or plumber's tape, is used on threaded connections to prevent leaks. Wrap 4-5 turns of PTFE tape around the threads of the mains water connection. The tape should cover the threads evenly but not excessively, as too much tape can interfere with the proper sealing of the connection. PTFE tape helps create a watertight seal by filling any small gaps in the threads.
• Install the New Tap: Position the new tap over the mounting holes in the sink. If the tap has pre-fitted hoses, ensure they are positioned correctly and are accessible. Align the tap so that it fits snugly into the holes. Make sure the tap is centered and positioned as desired before securing it.
• Secure the Tap: The new tap will come with a retaining nut that needs to be tightened to hold the tap in place. Initially, hand-tighten the retaining nut to hold the tap steady. Use a basin wrench or back nut box spanner to tighten the nut securely. These tools are specifically designed to reach and tighten nuts in tight spaces under the sink. Ensure the tap is firmly secured without wobbling. If needed, ask someone to hold the tap while you tighten the nut to ensure it stays properly aligned.
• Verify Alignment and Placement of Seals and Washers: Before you finish, check that the tap is correctly aligned with the sink and that all seals and washers are in their proper places. Seals and washers are crucial for preventing leaks. Ensure they are seated correctly around the base of the tap. Misalignment or improperly placed seals can cause water to leak out.

3. Reconnect to the Mains Supply

After securing the tap, you need to reconnect the plumbing lines:

• Reconnect the Hoses: Attach the flexible hoses from the new tap to the water supply lines. Begin threading the hoses onto the connections by hand to avoid cross-threading. Cross-threading can damage the fittings and cause leaks. Once the hoses are hand-tightened, use an open-ended spanner and adjustable pliers to tighten them securely. Be cautious not to overtighten, as excessive force can damage the connections or cause leaks.
• Check Connections: After connecting the hoses, double-check all fittings to ensure they are tight and properly aligned. Check for any signs of leaks around the connections. Use a cloth to protect the finish of the sink and tap while tightening to avoid scratches or damage.

4. Turn On the Water Supply

Restoring the water supply and checking the new tap’s functionality is the final step:

• Open Isolating Valves or Main Stopcock: Gradually open the isolating valves under the sink or the main stopcock to allow water to flow back into the system. Open the valves slowly to prevent sudden pressure changes that could cause leaks. This step is crucial to avoid any pressure surges that might damage the new tap or plumbing.
• Check for Leaks: Inspect all the connections and the area under the sink for any signs of leaks. Check both the connections where the hoses attach to the tap and the main water supply lines. If you find any leaks, tighten the connections as needed. Address leaks promptly to avoid water damage and ensure the installation is secure.
• Turn On the Taps: Gradually turn on the new tap(s) to allow the water flow to stabilize. Start with a low flow to let the system adjust and check for proper operation. Ensure that both hot and cold water flows are functioning as expected. If you notice any issues with water pressure or flow, double-check the connections and adjust as necessary.
