Water filter faucets play a huge role in providing clean and safe drinking water. However, like any other plumbing fixture, they can develop leaks over time. Addressing these leaks promptly is important for several reasons. First and foremost, leaks can lead to water wastage and create an outrageous water bill, or horrible water damage. Moreover, a leaking faucet can compromise the quality of filtered water, defeating the purpose of having a water filter in the first place. 

Common Causes for a Leaking Water Filtration Faucet

Two primary culprits behind leaks are worn O-rings/rubber washers and old or broken cartridges. Good news for you, both of these issues are an easy fix for you! You can find and replace the washers that are typically found in the handle or spout sections of the faucet. If you suspect the cartridge is the cause of the leak, locate it at the handle. The two most common types are washerless and ceramic disc cartridges, the latter being more modernly popular. 

Should You Repair or Replace?

After assessing the leak and identifying the potential causes, the next step is to determine whether repair or replacement is the best course of action. The age and overall condition of the faucet are important things to pay attention to in making a decision. If the faucet is relatively new and in good condition, repairing the specific faulty component, such as the washer or cartridge, may be sufficient. However, if the faucet is old and showing signs of wear and deterioration beyond the specific faulty component, it may be more practical and budget-friendly in the long run to replace the entire faucet.

How to Replace the Faucet Cartridge and Washers

Step 1: Turn Off Water Supply

Prior to disassembling the faucet, shut off the water supply at the isolation valve, usually located beneath the sink.

Step 2: Remove Handle

To access the internal components of the faucet, the handle needs to be removed. The method for removing the handle can vary depending on the faucet model. Some handles may have a set screw that needs to be loosened with an Allen key, while others call for a standard Phillips screwdriver. Refer to the manufacturer's instructions or consult a professional if you're unsure about the specific method for your faucet.

Step 3: Locate Cartridge

Once the handle is removed, you can access the cartridge, which is responsible for controlling the flow and temperature of water. It might be tedious to repair the cartridge yourself if you have no prior experience; however, we recommend replacing the unit for the best result. View our replacement cartridges.

Step 4: Reassemble & Test

After your desired method of either repairing or replacing your water filtration faucet, reassemble the components beneath the sink, and complete the assembly of the faucet itself above the sink top. 

To prevent future leaks and maintain the optimal functioning of the water filter faucet, regular maintenance is essential. This includes periodic inspection of washers, cartridges, and other components, as well as cleaning and descaling the faucet as recommended by the manufacturer. By staying proactive with maintenance, homeowners can prolong the lifespan of their water filter faucets and minimize the likelihood of leaks and other plumbing issues.
