How to install pur water filter on pull out faucet? Clean water is essential to daily life, contributing to our health, well-being, and overall quality of life. Its importance extends beyond mere hydration, as it also plays a vital role in cooking, cleaning, and various other household activities.

The PUR water filter is an invaluable tool to ensure our water’s safety and cleanliness. This advanced filtration system efficiently eliminates many contaminants, providing pure, clean water from our taps. Its benefits are manifold, from safeguarding our health to saving us the cost of bottled water.

This blog post will primarily focus on the installation process of the PUR water filter, guiding you through each step to ensure a seamless and efficient setup at your home.

Gather Your Materials

Before you begin the installation process, ensure you have the following tools and materials: the PUR water filter unit, an adjustable wrench, a screwdriver, Teflon tape, a bucket, and a towel. Ensure that the filter unit consists of a mount unit, a filter cartridge, and two faucet adapters.

Having all your materials ready before you start is paramount to a smooth and efficient installation. This not only saves you precious time but also helps avoid unnecessary interruptions. It also ensures you’re well-equipped to handle any unexpected situations during installation. So, before you start, check again to ensure you have all the necessary equipment.

Pre-Installation Preparation

To begin with, it is crucial to turn off the water supply to your faucet. This prevents unwanted water flow during installation, which could cause water damage or lead to an incomplete installation.

Clearing the sink area is equally important. Remove any dishes, soap dispensers, or other items around the sink. This provides ample space to work and ensures that your tools and filter components are easily accessible. Furthermore, clearing the sink area can prevent damage to your dishes or other items due to dropped tools or splashback from the faucet.

Finally, ensure the faucet is in the off position. This provides an added layer of protection against unexpected water flow during installation. Being thorough in these preparatory steps can make the process more efficient and less stressful.

Understanding Your Faucet

Pull-out faucets generally come in two common types: single-handle and double-handle. Single-handle faucets have one lever that controls both the water flow and temperature. On the other hand, double-handle faucets have separate handles for hot and cold water, allowing for more accurate temperature control. Both types may come with different connection points, so knowing your faucet type is essential before proceeding with the installation.

Identifying the appropriate connection points on your faucet is a pivotal step in the installation process. For single-handle pull-out faucets, look for a single-threaded stem underneath the sink where the hot and cold water lines connect. This is your connection point. For double-handle pull-out faucets, you’ll find two threaded branches for the hot and cold water lines separately. Always identify and mark these points before proceeding with the installation.

Assembly of the PUR Water Filter

Start the assembly process by attaching the filter cartridge to the mount unit. Ensure the filter cartridge is securely inserted into the slot in the mount unit. It should fit snugly, with no room for movement. Once the cartridge is in place, attach one of the faucet adapters to the mount unit. Use your hand to tighten the adapter until it is secure. Repeat the process with the second adapter. Finally, place the assembled filter unit onto your faucet, ensuring it fits securely and appropriately aligns with its spout.

Installation Process

To access the faucet’s connection point, you must first locate the threaded stem, typically found underneath the sink. Depending on your faucet type, you may have one or two threaded branches where the hot and cold water lines connect. Ensure the water supply is turned off before you begin. You may need an adjustable wrench to loosen any existing connections. After you’ve accessed the connection point, clean it thoroughly to ensure a secure and leak-free connection with the filter unit.

To attach the filter unit, align the faucet adapters connected to the filter unit with the faucet’s connection point. Once aligned, thread the filter unit onto the connection point, turning clockwise until secure. Ensure the filter unit is positioned correctly, with the faucet spout fitting through the filter opening. Repeat this process for both if your faucet has separate hot and cold connection points.

Ensuring all connections are secure is crucial to successfully operating your PUR water filter. Loose links can lead to leaks, which can cause water damage and interfere with the filter’s functionality. Moreover, it can result in an incomplete filtration process, potentially compromising the purity of your water. Therefore, double-check all connections after attaching the filter unit to ensure they are tight and well-sealed. However, be careful not to overtighten, as this can damage the faucet adapters and the filter unit.

Water Line Connections

Connecting the PUR water filter to the water supply is straightforward. After the filter unit has been securely mounted onto the faucet’s connection point, as detailed in the previous steps, it’s time to connect the water lines to the filter. Find the water supply lines previously connected to your faucet that you turned off during the pre-installation phase. Throw the line corresponding to the hot water onto the adapter located on the hot side of the filter unit, turning clockwise until secure. Repeat this step with the filter unit’s cold water line and the cold side adapter. Remember to tighten each connection securely, but avoid overtightening as it can damage the filter components.

Teflon tape, also known as plumber’s tape, is crucial in ensuring your connections are leak-free. To use Teflon tape, start by cutting off a small piece, approximately 6 inches long. Wrap this piece tightly around the threads of the faucet’s connection point before attaching the filter unit. The tape fills in gaps in the line, creating a tighter seal and preventing water from leaking. It is essential to wrap the tape clockwise around the threads so it won’t unravel when you screw on the filter. After applying the video, you can attach the filter unit described in the previous steps. With Teflon tape, you can enjoy the peace of mind of knowing your filter installation is secure and leak-free.

Testing Your Installation

Conducting a preliminary leak check is a crucial step post-installation. To do this:

  1. Slowly turn the water supply back on and closely observe the filter unit and all connection points.
  2. Look out for water dripping or streaming from the filter or around the faucet. If you spot a leak, immediately turn off the water supply and tighten the problematic connection.
  3. Repeat the leak check process until no leaks are detected.

Flushing the filter before use is crucial to remove any carbon dust or residues from the filter media. To do this, turn on the faucet and allow the water to flow through the filter for about 5 minutes. It is usual for the water to appear black or cloudy at first due to the carbon dust. After about 5 minutes, the water should run clear, indicating the filter is ready. Remember to always flush a new or replacement filter before using it for the first time.

Maintenance and Filter Replacement

Regular maintenance of your PUR water filter is key to ensuring its longevity and optimal performance. At least once a month, inspect the filter unit for any signs of damage or leakage. Clean the exterior of the filter unit with a soft, damp cloth to prevent any build-up of dirt or grime. Avoid using harsh chemicals or abrasive materials as they may damage the unit. Also, regularly check the condition of the faucet adapters and replace them if they show signs of wear or damage.

Replacing the filter cartridge is essential to maintaining your PUR water filter. The life of a filter cartridge varies based on your water usage, but a general rule of thumb is to replace it every 100 gallons or approximately every 2-3 months. To replace the cartridge, first, turn off the water supply. Then, remove the old filter cartridge by turning it counterclockwise until it releases from the mount unit. Please insert the new filter cartridge into the slot in the mounting unit and turn it clockwise until it’s secure. Remember to flush the new filter for about 5 minutes before using it, as described in the section on “Testing Your Installation.”


Most of the installation issues can be identified and resolved easily. One recurrent issue is leaks, which usually indicate loose connections or improperly applied Teflon tape. Ensure all connections are secure and the Teflon tape is correctly applied. If the water flow is too low, it could be due to a clogged filter cartridge. In this case, replacing the filter cartridge would solve the problem. If the filter unit doesn’t fit your faucet, double-check that you are using the correct adapter and the filter unit is suitable for your faucet type.

Regularly check the filter cartridge to ensure your PUR water filter functions correctly. A sudden change in the taste or smell of your water is usually a sign that your filter needs replacing. It’s also wise to maintain a schedule for filter replacement based on your water usage. Avoid running hot water through the filter, which can damage the filter media. Lastly, if you’re going on vacation or will not use the filter for a few days, turn off the water supply to the filter to prevent any unexpected leaks.
