This installation requires to have a hole in your faucet, one can be drilled, but we are presenting how we add a T- adapter to the main plumbing and use it to be able to add an additional faucet on your countertop. This helps so that you do not have to use a distracting adapter onto your main faucet. It is a clean and simple installation! #kangen #kangenwater #water #enagic #health #healthylifestyle #healthyrecipes #enagic #kangen #entrepreneur #business #diy
