How To Replace A Whole House Water Filter System and Installation

The whole house water filter needs to be replaced often for it to work efficiently in providing you with safe, clean drinking water. The filter is known to improve the surrounding air since the chlorine from the water is removed and cannot vaporize into the air. The manufacturers' advice is to replace the filter at least every three months. The correct procedural steps below will guide you through the process.

Step 1

Turn the water supply off. Shut down the water at the inlet side of the filter and the outlet side.

Step 2

Before unscrewing the holder that holds the water filter, relieve the water pressure. To reduce the pressure, turn the outside garden hose faucet on or turn the faucet on inside your house. Without depressurizing the unit first, it will be impossible to take filter cartridges off.

Step 3

Unscrew the housing that holds the filter. Take it all the way out and be careful not to lose the o-ring in the process.

Home filters play an important role in removing toxic contaminants from water and produce a clean and pure outcome. They are popular within households and require a simple installation.

Before installation, turn off the water system from its main shut off. Then, drain most of the water from the system and release the pressure by running the tap water from the lowest point in your home. Choose the location for your water filtration system. Preferably the filter should be near the shut-off value, so you can easily access the unit and change the filters.

Cut the Pipe

  1. Use the template provided with the water filter kit to mark the tub at the exact location where you want to cut it.
  2. Make two cuts using a pipe cutter and remove the marked section from the tube.
  3. Tighten the cutter onto the tube by using the twist handle until the blade lines up with your marked cut.
  4. As you continue to turn the handle, rotate the cutter around the pipe.
  5. Continue to rotate the cutter around the pipe until it cuts all the way through.
  6. Once the section is cut, remove the burrs inside the cut tube by using the reamer blade on the cutter.

Apply the Fittings

  1. On either of the cut ends, position a compression nut by placing the small end first and slide through. Then repeat the procedure with the other end.
  2. Pass a brass fitting onto the “in” and “out” ports of the filter housing.
  3. Install it according to the manufacturer's instructions provided with the kit.
  4. Double check to make sure there is a decent seal between the filter port and the fitting.
  5. Secure the fittings on the filter until they are close fitting but do not over-tighten.

Place the Filter

  1. Let the filter stay temporarily between the two ferrules by positioning it on the water line.
  2. Tighten the compression nuts to the fitting bodies.
  3. Using two wrenches, tighten the fittings and keep the filter upright and straight.

Turn on the Water

  1. Turn the valve to the “off” position.
  2. Turn the water back on by the "shut off" valve and check if there are any leaks of water in the filter kit.
  3. Fill the tank with water and start the filtering unit by switching the valve from the “off” to “filter” position.
