Tips for Installing a Water Purifier

You can install a water filter in just a few steps. Here are step-by-step instructions for installing a drinking water filter at your sink.

There are various types of water filter devices you can install in your kitchen including dual cartridge water filters. Keep in mind that the cartridges have to be changed about twice a year to maintain the quality and cleanliness of the water.

Here are step-by-step instructions for installing a drinking water filter at your sink:

Mount the dispenser. If you sink has an extra hole, this is where you can mount the water filter dispenser. If there is no hole, you will have to drill one in the sink. You can also drill a hole in the countertop.

Tap into cold water supply. First turn off the water supply. Open the faucet and drain the line. Then use a saddle valve to tap into the cold water supply. Drill a small hole and place the valve where the lance can fit into the hole that you drilled. Put the plate on the valve and tighten the nuts. Screw the lance into the valve.

Install the cartridge water filtration unit. You'll want to place the water filtration unit between the cold water line and the dispenser. Leave enough room to replace the water filter cartridge.

Connect the system. Now it's time to connect the system. Do this by cutting some plastic tubing to connect the saddle and the water filtration unit system. Use a wrench to press the tubing into the compression fitting. Then take it through the saddle valve. Then take the end of the tubing through another compression fitting and into the filtration unit. Tighten the nut.

Connect the system and the water dispenser. Cut another piece of tubing and run that tubing from the system to the water dispenser. You'll need to put compression fittings on both ends of the tubing as well as nuts. Insert the nuts on the system and the dispenser.

Turn water supply back on. After you've turned on the water supply, open the dispenser. Let the water run for a few minutes. This will get rid of air pockets and carbon particles.
