Do you want to have purer and healthier drinking water in your home? Installing an under-sink water purification and filtration system is certainly the most convenient solution. Not only do such systems save space, but they also provide higher-quality drinking water by filtering your water directly from the faucet.

However, many people may be concerned about the complexity of the installation process, when in fact, it can be easily completed by following some simple steps. This article will guide you through the entire installation process so that you can enjoy cleaner drinking water in your home.

What are some common problems encountered during installation?

Common problems when installing an under-sink water filter system include:

• Lack of space: Measure the space under the sink before installation and choose a water filter with a compact design.
• Leaking joints: use raw tape to seal and ensure all connections are tight.
• Reduced water pressure: choose a unit that is suitable for your home's water pressure and replace cartridges regularly.
• Difficulty in replacing cartridges: plan the location and make sure there is enough space for maintenance.
• Pipe mismatch: prepare adapters to connect pipes of different sizes.

With a good understanding of these issues, we can gradually begin to prepare tools to install the under-sink water filter system.

What tools are needed for installation?

The following tools are typically needed to install an under-sink water filtration system:

• Wrench: to tighten or loosen pipes and fittings.
• Screwdriver: to secure brackets and other components.
• Teflon tape: is used to seal pipe connections to prevent leaks.
• Electric drill: used to make holes in the cabinet and install brackets or other fixed parts (depending on the installation location).
• Tape measure: used to measure space and pipe lengths to ensure proper fit of equipment.
• Plumbing scissors: to cut and adjust the length of the pipes.

After preparing these tools, it is time to take out the sink water filtration system you bought and install it.

How to install an under-sink water filter system？

First of all, before installation, you should confirm in advance whether the water pressure in your home is suitable for the water purifier to avoid affecting the water flow effect.

Then make sure that all the parts of the water purification and filtration system are complete, including the three-way valve, inlet pipe, outlet pipe, mounting bracket (if any), filter cartridge, and so on. Then you can follow the detailed steps below for installation:

Step 1: Preparation

Turn off the water: Before you begin, make sure you close the cold water valve under the sink to avoid leaks during installation. Usually, the cold water valve is located under the sink and can be closed by hand by turning it clockwise.

Empty the under-cabinet space: Remove all items under the sink, including cleaning supplies and storage bins, to ensure that there is enough room to work and that there is enough room for future maintenance and cartridge replacement.

Step 2: Install the Water Inlet Valve Adapter

Remove the cold water pipe: Locate the connection between the cold water pipe and the faucet, usually a metal or plastic hose, and use a wrench to carefully loosen the pipe's nut. Carefully remove the cold water pipe, note that a small amount of residual water may come out, and have a towel or basin ready to catch the water.

Install the 3-way valve: connect the cold water pipe to the 3-way valve under the sink, one way to the faucet and the other to the water purifier. Tighten all joints with a wrench to make sure each connection is secure. Use raw tape to wrap the threads of the connections to increase sealing and prevent leaks.

Step 3: Install the water purifier body

Determine the water purifier installation location: Depending on the space under the sink, choose a location that is easy to operate and maintain, usually on the side of the sink cabinet.

Fix the bracket: Use a drill or screwdriver to drill holes inside the sink cabinet and fix the water purifier bracket.

Make sure the bracket is solid and can hold the weight of the water purifier. Install the main body of the water purifier on the bracket and make sure it is securely fastened in place for future cartridge changes.

Step 4: Connecting the inlet hose

Measure and cut the inlet pipe: Starting from the other outlet of the 3-way valve, connect the inlet pipe to the water inlet of the water purifier. Use a tape measure to measure the desired length of pipe to avoid excessive length or tangling. Use plumbing scissors to cut the appropriate length of the inlet pipe.

Connecting the inlet pipe: connect one end of the cut inlet pipe to the outlet of the 3-way valve and the other end to the water inlet of the water purifier.
Make sure each connection point is tightly connected and wrap the threaded portion with raw material tape to prevent leakage. Check again that all joints are secure.

Step 5: Connecting the Water Purifier Outlet Hose

Connect the outlet pipe: Connect the outlet of the water purifier to the outlet pipe and the other end to a water purification faucet or a dedicated water purification outlet.

If your system comes with a separate water purification faucet, you will need to drill holes in the sink to install the dedicated water purification faucet.

Step 6: Test the system

Turn on the water: Reopen the cold water valve under the sink and turn it on slowly to ensure that the water flows properly to the water purifier and faucet. Check for leaks at all connections, especially at the 3-way valve, inlet, and outlet hose connections. If any leaks are found, immediately turn off the water supply, tighten the connections, and re-wrap the raw material tape.

Exhausting and flushing the filter cartridge: When using the water purifier for the first time, and opening the water purifier faucet to expel the air from the system, the water flow may be a little erratic.

Continue to allow water to flow through the water purifier for several minutes until the water flow is steady and clear. There may be tiny carbon particles or air bubbles in the water from the initial installation, this is normal and can be eliminated by rinsing for a few minutes.

Step 7: Inspection and Adjustment

Final check: Make sure there are no leaks in all pipes and joints. Confirm that the water flow is normal and the water pressure is moderate.

Clean up the site: Put tools and equipment in order and remove any leftover packing materials or discarded pipes. Replace items under the sink.

Installation of an under-sink water system by following the above steps, and changing the filter cartridge regularly, is the key to maintaining water quality. You should check the fittings and piping at regular intervals after installation to ensure that the system is working properly.

How to choose the under-sink water filter system?

When choosing an under-sink water purification and filtration system, you need to consider the following points:

water quality issues: choose the right type of filtration according to the contaminants in the water, such as activated carbon (to remove chlorine), reverse osmosis (to remove heavy metals), etc.

Filtration capacity: Choose a filtration system that meets your household's water consumption, and make sure the capacity is sufficient to avoid frequent cartridge changes.

Cartridge Replacement Frequency: Understand the life span of the cartridge, TOKIT's water purification system can be used for at least 12 months.

Flow rate and water pressure: Ensure that the filter does not excessively affect the water pressure and choose a system with a moderate flow rate.

Space and Installation: Choose the right size system for the space under the sink and make sure it is easy to install and maintain.

Certification standards: Choose products with NSF certification to ensure reliable filtration.

Budget and Maintenance Costs: Consider both the purchase price and the long-term cost of filter cartridge replacement.
