Turn the water off: Turn off the water supply to the house by shutting off the main water valve. If you don’t have easy access to it, turn off the individual water supply valves that feed each fixture in the house.

Remove the garden hose from the Hose Bib Assembly: Before beginning the installation of a whole-house water filter for fluoride, it is essential to note that you must adequately remove the garden hose from the Hose Bib Assembly. This will be used to connect the filter assembly and inlet supply pipe. T

Allow the carbon tank to soak for at least 48 hours: Once it is installed, it needs to be conditioned by filling it with water and allowing the carbon to soak for a minimum of 48 hours. During this time, the system should not be connected to your main water line or any pipes entering it.

Reattach the garden hose: Reattach the water filter to the main water line, and reattach the garden hose back onto the main water supply. Make sure it is connected tightly and securely to avoid leaks or spills.

Slowly turn on the water: Start to turn on the water supply from outside. Make sure your water filter has been connected properly. When turning on the water, some gurgling and air will flow out of the filter. Allow it until all the air is gone, then close the valve tightly.

Please turn off the water

Please turn off the water: Before proceeding with the installation process, all water supplies that lead to your house must be turned off. To do this, locate the main shutoff valve and make sure it is turned off.

Remove the Hose Bib Assembly: Before installing the whole house water filter, remove the hose bib assembly (usually found in the area surrounding your main water line). To do this, turn off the water supply at the valve and then use a wrench to unscrew it from its plumbing connection.

Run the water through the downflow inlet side: Once the filter is mounted and in place, it is time to run water through it. Start by connecting the downflow inlet side of the filter to your cold water line. Depending on your setup, this may be a threaded or compression fitting. Using a threaded fitting, use the plumber’s tape or pipe compound on the threads to ensure a watertight seal. If you are using a compression fitting, ensure all components are hand-tightened and do not over-tighten them.

Please turn off the water: Before installing your whole house water filter, you must turn off the main water valve to install it safely. There must be no water running through the pipes while you are working.

Remove the Hose Bib Assembly: Remove the hose bib assembly. This is usually located near the main water line, consisting of an inlet valve and several pipes connecting it to the rest of the plumbing system. Please turn off the shutoff valves on either side of the assembly before unscrewing it from the main water line.

Unscrew the cover filter housing: Once you’ve found the location to install the whole house filter, begin by unscrewing the cover of the filter housing. Remove any existing filters from the inside and discard them. Place your new activated carbon water filter cartridge in the housing and make sure it is secure.

Remove the plastic covering from the sediment filter: Locate the sediment filter. It will be located near your main water line and will likely be covered with a plastic casing to protect it. Remove the plastic covering and set aside the screws or clips to secure it.

Place the sediment filter onto the standpipe: Begin by mounting the standpipe securely onto a flat surface such as a wall or floor. If you are mounting it onto a wall, use appropriate screws and anchors for your wall type. Once mounted, attach the sediment filter to the top of the standpipe where indicated.

Shut off the water: Turn off your house’s primary water supply line before installing. This will prevent any water from entering your plumbing system during installation and ensure no water is wasted.

Attach the filter cover to the mounting bracket: Once the filter housing is connected to the water line, attach the cover to the mounting bracket by inserting the cover’s tabs into the slots in the bracket and pushing down until it clicks into place. Secure with screws if necessary.

Attach the mounting bracket to the wall: Before attaching the filter body, use a level to ensure that the mounting bracket is perfectly straight. Use two screws or bolts (depending on which type of hardware you have) to attach it securely to the wall.

Install the fittings: To install the fittings, you will need a wrench and Teflon tape. First, remove the water main shutoff valve from your existing plumbing system.

Connect the incoming water supply: A whole house water filter will require a connection to the incoming water supply line. This may be a cold water line, a hot water line, or both. To make this connection, you must determine which type of pipe your incoming lines are made from. If it is copper, use compression fittings and teflon tape to secure the connections. If the pipe is made from PVC, you will need clamps and a solvent adhesive.

Connect the outgoing water supply to the outlet: Once you have installed the filter system, it’s time to connect the outgoing water supply to the outlet.

Turn on the water supply and check for leaks: Turn on the water supply to your house and check for any signs of leakage. Make sure that all connections are correctly tightened and sealed. This is a crucial step before beginning the installation process, as it ensures that no water damage occurs while installing the filter.

A whole-house water filter for fluoride can remove various contaminants from your water, including chlorine, chloramines, sediment, heavy metals such as lead and copper, volatile organic compounds (VOCs), and of course, fluoride. Depending on the filter you choose, it may also be able to remove other types of contaminants, such as bacteria, cysts, and pharmaceuticals. Many filters also come with carbon pre-filters to help reduce sediment and foul odors.

Effects Of Fluoride On Water

  • Fluoride is naturally found in water, soil, and air. It is used to prevent tooth decay and strengthen tooth enamel.
  • When fluoride levels are too high, it can cause discoloration of teeth (dental fluorosis) and impaired brain development in babies and young children.
  • High fluoride levels may also increase the risk of kidney and bone damage in adults.
  • The U.S. Environmental Protection Agency (EPA) sets safe drinking water standards for fluoride at 4 milligrams per liter (mg/L).
  • If your local public water supply contains more than this, you may consider installing a whole-house water filter for fluoride.


No water flow: Check that the power is on and all connections are secure. Check the water pressure – if it’s too low, try adjusting the water pressure valve. You may need to replace your filter cartridges if there’s still no water flow.

Media discharging during backwash: Place a bucket with a drain hose connected to it near the discharge valve. Connect the other end of the drain hose to a nearby floor drain or sink. The water produced during backwashing will be discharged into this bucket through the drain hose.
Poor performance: Once you have gathered the necessary materials and tools for installation, it’s time to begin. Start by turning off the main water supply to your home. Then locate the shutoff valve for your water filter system, usually near a cold water pipe leading into the house. This is where you will connect the whole house filter.

Leak in distributor tube: If you find a leak in the distributor tube, you need to fix it immediately.

  • Shut off the main water supply and drain any remaining water from the distribution tube.
  • Take apart the distribution tube where the leak is located. You may need to cut away part of the tubing damaged by corrosion or other damage.
  • Once the damaged section of the tube is removed, replace it with a new piece of tubing and secure it to the existing pipe with clamps.

Softener fails to regenerate: Your water filter may stop working due to a failure in the regeneration process. If you have a softener that uses salt, it’s possible that the brine tank has not been filled with enough salt or has too much sediment and needs to be cleaned out. Furthermore, when replacing your filter media, ensure it is compatible with your system.
