Installing a Water Purifier

 
 

Water purifiers remove impurities or sediment from tap water. There are two types of water purifiers: faucet-mounted and in-line. Faucet-mounted water purifiers are easy to install, but the filter has to be changed frequently. The in-line system may be more costly, but it is more comprehensive and requires only an occasional filter change. In-line systems are not difficult to install.

MATERIALS:


 

Step 1

 Step 1: Position the water purifier & attach the bracket

Position the water purifier. Set the bracket so the bottom of the purifier hangs at least 3 inches above the cabinet floor. This will allow you to remove the cartridge easily. Predrill the holes, then attach the bracket to the wall with wood screws. You may find it easier to attach the bracket with the cartridge removed.

  

Step 2

Step 2: Cut the water supply line at least 3 inches above the shutoff & drain water

To tap into the water supply line, place a bucket under the water line. Turn off the shutoff valve for the line. Use a tubing cutter to cut into the supply line at least 3 inches above the shutoff if the line is copper or plastic. If the line is a braided flexible supple line do not cut it. Drain the line into the bucket.

  

Step 3

Step 3: Install a compression fitting on each end of the cut line

Install a compression fitting on each end of the cut line. Insert the lines to and from the water purifier into the compression fitting. Tighten the compression nuts for the fitting using two adjustable wrenches.  Braided supply lines can have the compression fitting threaded to them.

  

Step 4

Step 4: Connect the inlet and outlet lines to the water purifier

Connect the inlet and outlet lines to the tap water purifier. Slide the compression nuts over each line. Place compression rings over each end. Insert the lines into the water purifier, and tighten the nuts using an adjustable wrench.

Step 5: Flush the system, install the cartridge and turn the water back on
