 Select the tap position: Select the position suitable for your BWT water filter. The tap must be installed to allow easy access to the filter cartridge and its housing.

 Mark the surface to indicate the center: After determining the desired location for your BWT water filter, mark the surface with a marker or pen to indicate its center. This will help you make sure that it is mounted properly and securely.

 Drill a hole: For installing a BWT water filter, drill a hole into the wall where you would like to install the filter. Make sure it’s big enough to fit the fittings, so check before proceeding. An incorrect hole size could lead to leaks and other issues.

 Insert threaded section into the hole: Insert the threaded section of the filter into the hole in your water line. Tighten this connection with a wrench.

 Lock in place using the spanner: Lock the tap in place using the spanner provided in the package. Be sure to apply pressure evenly until it is completely secured.

Remove the saddle from the back plate: Twist the large nut counterclockwise until it comes off. Pull out the saddle from the back plate and discard. Make sure to clean out any debris that may be inside before you install your BWT water filter.

 Screw male thread into the saddle: Now, screw the male thread into the saddle using a spanner or adjustable wrench. Ensure the spanner does not slip off and damage the saddle threads; otherwise, it won’t fit properly.

Firmly push the tube: Once the tube has been connected to the input/output ports of the BWT filter, it needs to be firmly pushed in. To do this properly, use two hands and press down with equal pressure on both ends of the tube until it is securely attached.

 Turn on the water supply: turn on the cold water supply at the main valve and keep it flowing steadily.


 Allow the water to run for 3 minutes: run the water from a cold tap for 3 minutes after installing the BWT filter. This allows the newly installed BWT filter to become fully operational, as the water will pass through the new filter system for the first time. During this process, you must discard any water that has been filtered by running it down a sink or drain.

Tighten the sump back onto the housing: Tighten it back onto the housing, ensuring it is properly sealed.

Turn on the water supply: Turn it on now if it is not already on. Locate the main shut-off valve and turn it clockwise until water flows from the faucet.

Allow the filter water tap to run: It is important to run it for about two minutes once you have installed your BWT water filter. This allows sufficient time for the air in the pipe and filter system to be flushed out and replaced with fresh, clean water.

Check thoroughly for leaks:  Before installing the BWT water filter, check for any leaks. Inspect the filter and connection components thoroughly and the pipe connections. If there are any signs of a leak, make sure to fix them before continuing with the installation process.


Leaks between head and cartridge: Ensure you have tightened the filter head correctly. If this does not resolve the issue, try replacing the O-ring seal between the head and cartridge with a new one.

Leaks: From fittings: If there is a water leak from the fittings, try to tighten them with a wrench. If the leak persists, you may need to replace the fitting.

Leaks: On saddle valve connection: If you notice a drip from the saddle valve connection, it can be solved by tightening the nuts on the valve. If that does not work, there may be a need to replace the O-ring or the whole valve body.

Leaks: On tap/tubing connection: If you notice any water leakage from the tap/tubing connection, it is important to check if all the parts are tightly connected. Make sure that all the nuts and washers are securely fastened. If necessary, unscrew these components and re-tighten them for a secure seal.

Maintenance And Safety Tips

The maximum temperature of cold water should be 25 degrees: It is recommended to use cold water (25 degrees or lower) for optimal filtration performance. The high temperature of the water may reduce filter life and the efficiency of filters.

Do not install BWT water filter near hot water pipeline: BWT water filters are designed to be installed near cold water pipes only. If you try installing the filter near a hot water pipe, it will not work properly, and you may experience reduced performance or even complete failure.

Avoid using a wrench. It will damage the casing: When installing a BWT water filter, it is important to avoid using a wrench or any other tools that may damage the casing. Doing so will not only compromise the integrity of the product but also potentially cause harm to users in the long term.

Clean filter bowl with warm soapy water: The filter bowl is the main component of your BWT water filter. To ensure that it works properly, you should clean it regularly with warm soapy water. This will help remove dirt and other debris from the bowl and reduce bacteria buildup.

 Check joints regularly for leaks: It’s important to ensure all the joints are secure and there are no leaks. This can be done by regularly checking the tightness of each joint connection. It’s also important to check the actual filter itself for any signs of damage or leakage and inspect other parts, such as hoses and valves. If any leaking is detected, it should be addressed immediately to avoid potential damage to the system.

Cartridges should be replaced every three to six months: To ensure your BWT water filter is performing optimally, it is important to replace them every three to six months. This will enable the filter to effectively remove bacteria and other contaminants from your drinking water.

Do not use BWT filter with biologically unsafe water: Use BWT water filter only for biologically safe water. If you are uncertain about the quality of your water, have it tested by a professional before installing and using a BWT filter.
