How is the undersink filter installed?
The undersink filter must be installed on the cold water tap of your sink only. The filter comes equipped with two fittings and tubing to make the install as easy as possible. The undersink also has a Ceramic Faucet option that would allow you to have a separate tap on your counter for filtered water. Make sure it is possible to cut a small hole in your sink or countertop before choosing the separate faucet option however. Porcelain sinks cannot be drilled.
