Things to Consider

Installing a new kitchen tap can be a game-changer for your sink, but there are several factors you should consider before diving in:

  1. Tap Size and Sink Compatibility: Ensure that the new tap is compatible with your sink's pre-drilled holes and size. The tap should fit comfortably without any overhang.
  2. Style and Finish: Choose a tap style and finish that complements your kitchen decor. Remember, the tap is not just functional but also an aesthetic element of your kitchen.
  3. Ease of Installation: Some taps are easier to install than others. If you're doing it yourself, consider a tap that comes with detailed installation instructions or even a DIY-friendly design.
  4. Water Pressure: Make sure the new tap is suitable for your home's water pressure system. Some taps require a certain level of pressure to function optimally.
  5. Your Budget: Taps come in a wide range of prices. Determine your budget beforehand and choose a tap that offers the best balance between cost and quality.
  6. Tap Features: Some taps come with additional features like pull-out sprayers, water filters, or touchless operation. Consider if these features align with your needs and preferences.

By taking these factors into account, you'll be better equipped to choose the perfect tap for your kitchen.

Step 1: Removing the Old Tap

The task of removing an old kitchen tap might seem daunting, particularly if you're embarking on this DIY journey. But don't worry, here's a step-by-step guide to help you navigate through the process:

  1. Be Mindful of Corrosion: Older taps can have corroded fittings, which necessitate extra caution during the removal process.
  2. Shut Off the Water Supply: This is the first and most crucial step. It ensures you can safely disconnect hoses or pipes without the fear of leaks.
  3. Disconnect Hoses and Pipes: Once the water supply is off, carefully remove any connected hoses or pipes.
  4. Loosen the Faucet: Use your adjustable wrench to disconnect the faucet from its mounting bracket.
  5. Remove the Faucet: With the aid of a pipe wrench, gently loosen and extract the faucet itself.

By carefully following these steps, you'll be able to successfully remove your old kitchen tap, paving the way for a sleek, modern replacement.

Step 2: Installing the New Tap

The installation of a new kitchen tap can be an exciting upgrade. Here's a step-by-step guide to ensure a smooth process:

  1. Measure Twice, Buy Once: Use a tape measure to accurately gauge the dimensions of the sink holes and their distance apart. This will help you pick a tap that fits your sink seamlessly.
  2. Safety First: Always turn off the water supply before you begin the installation to prevent any mishaps.
  3. Remove the Old Tap: If the old tap is still in place, use a basin wrench to remove it.
  4. Prep the New Tap: Apply a layer of plumber's putty around the base of your new tap. This will help create a water-tight seal.
  5. Insert the New Tap: Position the new tap into the sink holes and hand-tighten the mounting nuts to secure it in place.
  6. Secure the Tap: Use a wrench to give the mounting nuts a final tighten. Be mindful not to overtighten, as this could damage the tap or sink.
  7. Reconnect Everything: Reattach any hoses or pipes and turn the water supply back on.
  8. Test Run: Check your new tap for any leaks. If all's well, enjoy your new kitchen feature!

Remember, careful installation will ensure your new tap functions well and looks great in your kitchen! You can see how to install a boiling water tap here.


Even with the most careful installation, kitchen taps can sometimes run into problems. Here are some common issues and their solutions:

  1. Leaky Tap: If your tap is dripping, it may be due to a worn-out washer. You'll need to remove the tap handle and replace the faulty washer.
  2. Low Water Pressure: If the water pressure from your tap is lower than usual, it could be due to a blocked aerator. Unscrew the aerator from the end of the tap, clean out any debris, and screw it back on.
  3. Loose Tap: If your tap wobbles, it's likely the mounting nuts under the sink are loose. Tighten them with a wrench.
  4. Squeaky Tap: A squeaky tap often means the spindle or other components need lubrication. Remove the tap handle and apply plumber's grease.
  5. Stiff Tap Handle: If the tap handle is hard to turn, it could be due to sediment buildup. Remove the handle and clean the stem.
  6. Hot or Cold Water Not Flowing: If either hot or cold water isn't flowing, check the shut-off valves under the sink to ensure they're fully open.

Remember, always turn off the water supply before attempting any repairs. If you're not comfortable doing these fixes yourself, don't hesitate to call a professional plumber. You can also find some answers on our troubleshooting FAQs page.

Maintaining Your New Tap

  1. Routine Care: Regularly clean your tap using mild dish soap and warm water, check for leaks, and handle the tap gently to prevent wear and tear.
  2. Aerator Maintenance: Keep the aerator clean by routinely unscrewing it and removing any debris to maintain optimal water flow.
  3. Address Issues Promptly: If you notice a decrease in water pressure, unusual noises, or constant dripping, address these issues promptly either by doing DIY fixes or hiring a professional. This proactive approach can prevent small problems from turning into bigger, more costly ones.
