Upon arrival customer informed me that she wanted to install an RO faucet that she purchased. I was originally informed that she wanted to install a whole RO system however customer was mistaken. It was only the faucet that she needed replaced. New RO faucet was 1/4” connection which was different from previous connection. I needed to change piping around to make new faucet work. Advised customer that she would need to find a new place to mount new faucet. Tested new faucet for leaks. No leaks
