Turn off the water supply

To turn off the water supply to your water filter candle, start by locating the main water valve. This is usually found underneath the handle of the faucet. Next, using a screwdriver, carefully pry up the handle from left to right. Apply slow, even pressure to gradually lift the handle and avoid applying force unevenly, which could damage the handle or valve. Once the handle is removed, you will have access to the water filter candle.

At this point, it is important to remember that different water filter candles may have specific procedures for turning off the water supply. For instance, some candles may have a shut-off mechanism built into the handle, while others may require you to close a valve located elsewhere on the system. Always refer to the manufacturer's instructions or a trusted guide specific to your model.

If you are unable to locate specific instructions for your model, a general guideline is to look for a valve or knob near the water filter candle housing. This valve controls the water flow to the candle and should be turned clockwise to shut off the water supply. Ensure that the valve is tightly closed to prevent any water leakage.

Once the water supply is turned off, you can proceed to remove the old water filter candle. This typically involves unscrewing or unclipping the candle from its housing. Be sure to follow any specific instructions provided by the manufacturer for your particular model of the water filter candle.

If you have any concerns or are unsure about any steps, it is always best to consult a professional or seek advice from a trusted source to ensure you do not damage your water filtration system or compromise the water quality.

Disconnect the filtration system

Disconnecting the filtration system is a crucial step in changing your water filter candle. This process will ensure that you can safely remove the old candle and install a new one. Here is a step-by-step guide to help you through the process:

Firstly, locate the main water valve and turn it off. This step is essential to shut off the water supply to the filtration system. It is important to note that the valve may vary in appearance depending on your system, but it is typically located near the faucet or under the sink.

Once the water supply is turned off, you can proceed to disconnect the filtration system from the water source. This step may involve unscrewing or detaching hoses or pipes connected to the system. Be gentle during this process to avoid any damage to the connections or the system itself.

After disconnecting the hoses or pipes, you will need to release any built-up pressure in the system. This can be done by slowly opening the faucet connected to the filtration system. You may need to place a bucket or container under the faucet to collect any remaining water that drains out.

Now that the water supply is turned off and the system is disconnected, you can carefully remove the housing containing the filter candle. This step may require unscrewing or unclipping any fasteners or seals that hold the housing in place. Be sure to refer to the manufacturer's instructions or a professional guide for your specific model to ensure that you are safely and correctly removing the housing.

Once the housing is removed, you will have access to the old water filter candle. Proceed with caution as the candle may still contain some water. Place it in a safe location, ready for the next steps of removal and replacement.

By following these steps, you have successfully disconnected the filtration system, allowing you to safely remove and replace your water filter candle. Remember to refer to specific instructions for your filtration system model and always exercise caution when working with water systems.

Clean the housing

After opening the housing, carefully remove the old water filter candle. It may be stuck inside the housing, so you might need to twist it back and forth to loosen it before pulling it out. Inspect the O-ring for any signs of damage and lubricate it with food-grade lubricant. Never use silicone or petroleum-based lubricants as they can contaminate your water.

With the old candle removed, it's time to clean the housing. Start by removing any large debris or sediment that may be present. Use a soft brush or cloth to gently wipe down the inside of the housing, ensuring that all surfaces are free of dirt and grime. Pay close attention to the O-ring seal and make sure it is thoroughly cleaned. Rinse the housing with clean water to remove any remaining debris or cleaning solution residue. You can use a mild detergent solution for cleaning, but be sure to rinse thoroughly to avoid leaving any soap residue behind.

If you notice any mineral deposits or scale buildup inside the housing, you may need to use a mild acid solution for descaling. Prepare a solution of equal parts white vinegar and water, and carefully pour it into the housing. Allow it to sit for several minutes to loosen the mineral deposits. Then, use a soft brush or cloth to gently scrub away the deposits. Rinse the housing thoroughly with clean water to remove any vinegar residue. Ensure that the housing is completely dry before installing the new water filter candle.

It is important to keep the housing clean and well-maintained to ensure the effectiveness of the water filtration system. Regular cleaning can help extend the life of the water filter candle and maintain the quality of your filtered water. By following these steps, you can ensure that your water filter housing is properly cleaned and maintained.

Install the new candle

To install the new candle, start by ensuring the filtration system is clean and dry. Insert the new candle—ceramic, stainless steel, or roller-filter—into the designated slot, making sure it fits securely. If you are installing a ceramic candle, tighten any fasteners or seals according to the manufacturer's instructions to prevent leaks. Prime the candle by soaking it in clean water for the specified time to activate its filtration capabilities. Once primed, reconnect the filtration system to the water source and allow water to flow through the new candle.

After installing the new candle, insert the handle and adjust the direction of the handwheel. When the handle is on both sides, the water is turned off. Install the screws and cover the blue cover on the right, so that the new water filter candle is replaced. You should also test the filtered water for quality before consumption.
