3. Turn on the water at the saddle valve or water line and check the system for leaks. If there are leaks, check connections or repeat cartridge installation.

4. Flush 5 gallons through the system (it takes approximately 10 minutes). Residual air may cause temporary cloudiness in water. Place protective shroud back on bracket.

Conventional under sink filter

The feed water is sourced from the undersink cold water pipe. It passes through a flexible plastic tube and gets to the water filter. After filtration, it is transported from the filter to the dedicated filter faucet through another flexible plastic tube. The user gets the filtered water from this dedicated faucet right on the top of the sink. The filtration process starts when the user opens the tap, hence the system requires constant pressure to send the water from the cold water pipe to the filter and finally out of the faucet.

Simple under sink water filter

The source water leaves the cold water supply to the filter for filtration and finally dispensed through the regular water sink faucet. The hot water does not undergo filtration. The more common version is one without a distinct ledge as the flexible undersink pipes are easier to use. Unlike the hard copper undersink pipes, the flexible pipes facilitate a simple and cost-effective DIY installation.
