Materials Needed for Install An Outside Tap

To successfully install an outside tap, you will need the following materials:

Tap kit

A tap kit includes all the necessary components for installing an outside tap, such as the tap itself, fittings, and mounting hardware.


Piping is required to carry water from the main water source to the outside tap. It is essential to choose piping suitable for outdoor use.

Pipe cutter

A pipe cutter is a tool used to easily and accurately cut the piping to the required length.

Adjustable spanner

An adjustable spanner is a versatile tool that will come in handy for tightening and loosening various fittings during the installation process.

PTFE tape

PTFE tape, also known as plumber’s tape, is used to provide an additional seal against leaks. It is usually wrapped around the threaded fittings to ensure a secure connection.

Plumbers’ putty

Plumbers’ putty is a sealing compound that is applied around the base of the outside tap to prevent any water leakage.


A drill is necessary for creating a hole in the wall to accommodate the piping and tap.

Hose connector

A hose connector is required if you plan to attach a garden hose to your outside tap.

Waterproof sealant

Waterproof sealant will be used to ensure a tight seal between the connector and the tap, preventing any potential leaks.

Measuring tape

A measuring tape is necessary for accurately measuring the distances and dimensions required for proper installation.

Step 1: Selecting the Location

Choosing the right location for your outside tap is crucial for convenience and functionality. Consider the following factors when selecting a suitable position:

Locating an appropriate position

Look for an accessible spot on an external wall near the area where you will need water. Avoid placing the tap too high or too low, ensuring it is easily reachable for everyday use.

Checking local regulations

Before proceeding with the installation, check your local regulations to ensure compliance with any legal requirements or permits needed for installing an outside tap.

Considering convenient access

Think about where you will need access to water outside your home. Installing the tap in close proximity to an outdoor kitchen, garden, garage, or any other area where water requirements are frequent will ensure convenience.

Finding a nearby water source

Identify the nearest water source inside your home, such as a bathroom or kitchen. This will make it easier to connect the tap to the water supply.

Step 2: Turning Off the Water Supply

Before starting any work, ensure you turn off the water supply to avoid any accidents or water damage. Follow the steps below:

Locating the stopcock

Locate the stopcock, which is typically situated near the main water meter or where the water supply enters your property. It may be in the basement, garage, or an outside enclosure.

Turning off the water supply

Using an adjustable spanner, turn the stopcock clockwise until it is fully closed. This will shut off the water supply to your home.

Checking the water is off

To verify that the water supply is indeed turned off, open a faucet or tap inside your home and ensure that no water is coming out. Once confirmed, you can proceed with the installation process.

Step 3: Drilling the Hole

To install your outside tap, you will need to create a hole through the wall. Follow these steps:

Deciding on the hole size

Determine the appropriate size of the hole required for your piping and tap kit. Refer to the instructions provided with your tap kit to ensure the correct hole size.

Using a template or guide

If available, use a template or guide provided with your tap kit to mark the area for drilling. This will help ensure accurate placement of the hole.

Marking the position

Using a measuring tape, mark the position on the external wall where the hole needs to be drilled. Double-check the measurements before proceeding.

Drilling the hole

Using a drill and an appropriate-sized drill bit, carefully create a hole through the marked position on the external wall. Take care to keep the drill perpendicular to the wall to ensure a clean hole.

Step 4: Preparing the Tap Kit

Before installing your outside tap, it is essential to prepare the tap kit. Follow these steps:

Assembling the tap kit

Refer to the instructions provided with your tap kit and assemble the various components. This may involve attaching fittings or connecting the tap to the mounting hardware.

Applying PTFE tape

To prevent any potential leaks, apply PTFE tape to the threaded areas of the fittings. This provides an additional seal and ensures a tight connection.

Checking for leaks

After applying the PTFE tape, check each fitting to ensure a proper seal. Tighten any loose fittings to prevent leaks during installation and use.

Step 5: Connecting the Piping

Connecting the piping is an important step in the installation process. Follow these steps:

Choosing the appropriate piping

Select the appropriate piping material and size based on your requirements and the tap kit specifications. Consider using durable piping suitable for outdoor use.

Measuring and cutting the pipe

Using a measuring tape, measure the required length of piping to connect the tap to the water source. Use a pipe cutter to accurately cut the pipe to the measured length.

Attaching the pipe to the wall

Securely attach the pipe to the wall or on a suitable surface using pipe clips or brackets. This will help support the piping and prevent any unnecessary strain.

Connecting the tap

Connect the piping to the tap using the provided fittings. Ensure a tight connection to prevent any leaks.

Step 6: Securing the Tap

Ensuring the stability of your outside tap is crucial for its longevity and functionality. Follow these steps:

Ensuring stability

Check that the tap is securely mounted and stable. A loose tap can cause leaks and become a safety hazard. Use the appropriate mounting hardware provided with the tap kit to secure it in place.

Using plumbers’ putty

Apply a small amount of plumbers’ putty around the base of the tap before attaching it to the mounting hardware. This will create a waterproof seal and prevent any water leakage.

Tightening the fittings

Using an adjustable spanner, tighten all the fittings and connections. Avoid over-tightening, as this can damage the tap or cause leaks.

Step 7: Testing for Leaks

Before completing the installation process, it is vital to test for any potential leaks. Follow these steps:

Turning on the water supply

Carefully turn on the water supply by slowly opening the stopcock in a counterclockwise direction. Allow the water to flow through the newly installed outside tap.

Checking for any leaks

Inspect all connections, fittings, and the tap itself for any signs of leaks. Pay close attention to areas where piping meets the tap and around the threaded fittings.

Rectifying leaks if found

If any leaks are detected, turn off the water supply and carefully tighten the fittings that are causing the leaks. Use an adjustable spanner to ensure a secure connection.

Step 8: Attaching the Hose Connector

If you plan to attach a garden hose to your outside tap, follow these steps to install a hose connector:

Selecting a suitable connector

Choose a hose connector that is compatible with your outside tap. Consider the size and type of the tap to ensure a proper fit.

Applying waterproof sealant

Apply a thin layer of waterproof sealant to the threads of the hose connector. This will help create a watertight seal when attaching it to the tap.

Attaching the connector to the tap

Using an adjustable spanner, carefully attach the hose connector to the outside tap. Tighten the fitting securely, but avoid over-tightening to prevent damage.

Step 10: Regular Maintenance

To keep your outside tap in good working order, perform regular maintenance. Follow these steps:

Checking for leaks

Regularly inspect all connections, fittings, and the tap itself for any signs of leaks. If any leaks are detected, promptly address and repair them to prevent further damage.

Cleaning the tap

Clean the outside tap regularly to remove any dirt, debris, or mineral buildup. Use a mild detergent or cleaning solution suitable for outdoor use and rinse thoroughly.

Protecting the tap in winter

Before the arrival of freezing temperatures, it is essential to protect your outside tap from freezing. Disconnect and drain any hoses, and cover the tap with an insulated cover or wrap it with insulating material to prevent freezing-related damage.

By following these step-by-step instructions, you can successfully install an outside tap. Remember to prioritize safety and take necessary precautions during the installation process.
