Is it OK to use a water filtration faucet as the only faucet in a wet bar? It will not be hooked up to a filtration device. I only want cold water available in that location.

I see no problem with that. Is there a hot and cold supply now, or are you adding the water line for a new sink? If adding, I would suggest running both hot and cold for future just in case you decide you want hot later on.

Agree with previous post: should present no problem. Make sure you cap off cold water outlet on the bottom of the faucet. Otherwise you will have water leaking through the unused hot water outlet. Milo

I was thinking they were going to use something along the lines of an R.O. fuacet. Only has one supply. But good catch, if the faucet has both hot and cold connections, cap the hot.

Thank you both. There is no existing water supply at this time. Good idea to run both. The faucet we are thinking of purchasing is for a water filtration system (RO) and only has cold.
