Fitting a washing machine tap is a common task that many homeowners may need to do when installing a new washing machine or replacing an old tap. The washing machine tap is essential for providing water supply to the appliance, and it’s crucial to ensure it is installed correctly to avoid any leaks or water damage. If you’re a DIY enthusiast or someone who loves taking care of home projects, fitting a washing machine tap can be a rewarding and straightforward task. In this step-by-step guide, we will walk you through the process of fitting a washing machine tap, ensuring that you can complete the job with confidence.

Tools and Materials You’ll Need

Before you start the installation process, make sure you have the necessary tools and materials ready. Here’s what you’ll need:


  • Adjustable wrench
  • Screwdriver
  • Pipe cutter or hacksaw
  • PTFE tape (also known as plumber’s tape)


  • Washing machine tap
  • Isolating valve (optional but recommended)
  • Flexible hose or copper tubing (depending on your setup)
  • Rubber washer or O-ring

Step 1: Turn off the Water Supply

Before you begin any plumbing work, it’s essential to turn off the water supply to the area where you’ll be installing the washing machine tap. Locate the main water supply valve in your home and shut it off. If there’s no isolation valve for the specific water line you’re working on, you may need to turn off the main water supply.

Step 2: Choose the Location

Choose a suitable location for the washing machine tap. It should be near the washing machine and easily accessible. If possible, install an isolating valve at this point to allow for easy future maintenance without having to turn off the main water supply.

Step 3: Prepare the Water Supply Pipe

If you already have an existing washing machine tap that you’re replacing, you’ll need to remove it first. Use an adjustable wrench to loosen and disconnect the old tap from the water supply pipe.

Step 4: Install the Washing Machine Tap

Next, install the new washing machine tap. Wrap PTFE tape around the threaded end of the tap to create a watertight seal. Insert the tap into the prepared water supply pipe and use an adjustable wrench to tighten it securely.

Step 5: Connect the Flexible Hose or Copper Tubing

Depending on your setup, you’ll either connect a flexible hose or copper tubing to the washing machine tap. If using a flexible hose, make sure to use a rubber washer or O-ring to ensure a tight seal.

Step 6: Turn on the Water Supply

Once you’ve connected the hose or tubing, turn on the water supply at the isolating valve (if installed) or the main water supply. Check for any leaks around the washing machine tap and connections. If you notice any leaks, tighten the connections further or replace any damaged components.


Fitting a washing machine tap is a relatively simple task that can be completed by DIY enthusiasts and homeowners with basic plumbing skills. By following the step-by-step guide provided in this article and using the right tools and materials, you can ensure a successful installation that provides a reliable water supply to your washing machine. Remember to turn off the water supply before starting any plumbing work and to check for leaks after the installation is complete.


  1. Do I need to install an isolating valve for the washing machine tap? While it’s not always necessary, installing an isolating valve is recommended as it allows for easy maintenance and repairs without disrupting the main water supply.
  2. Can I use a washing machine tap for other appliances? Yes, washing machine taps can be used for other appliances that require a water supply, such as dishwashers.
  3. How do I know if my washing machine tap is compatible with my washing machine hose? Check the specifications of both the tap and the hose to ensure they have compatible fittings. If not, you may need to use an adapter or replace the hose with one that fits.
  4. What should I do if I encounter a stubborn connection during the installation? If you encounter a stubborn connection, use an adjustable wrench and apply gentle but steady pressure to loosen the fitting. Avoid using excessive force, as this could cause damage.
  5. Can I install a washing machine tap on my own, or should I hire a professional? If you have basic plumbing skills and feel confident in your abilities, you can install a washing machine tap on your own. However, if you are unsure or unfamiliar with plumbing work, it’s best to hire a professional to ensure a proper installation.
  6. How often should I check the washing machine tap for leaks? It’s a good idea to check the washing machine tap and connections periodically for leaks, especially after any maintenance or repairs to the washing machine.
  7. Can I reuse the old rubber washer or O-ring from the previous washing machine tap? It’s best to use a new rubber washer or O-ring to ensure a proper seal and prevent leaks. Over time, rubber components can degrade, so using a new one is recommended.
  8. What should I do if I notice a leak after the installation? If you notice a leak, turn off the water supply immediately and check all the connections. Tighten any loose fittings, replace any damaged components, and turn the water supply back on to check for leaks again. If the problem persists, consider seeking professional help to diagnose and fix the issue.
