I had a plumber last week install/replace an old bathroom faucet. He remarked that the faucet I had provided (a special order slant back unit from a plumbing supply house) "was backwards." Link to faucet sales site.
This guy is a top plumber, well known and respected, been working at this for probably 20 or more years and everyone swears by him, so I didn't question it.
Now, after he rebuilt it, what I have is a faucet where the knobs rotate clockwise for hot and counter clockwise for cold. I did not notice until I was shaving and it seems wrong and I compared to other bathroom faucet and it was the opposite.
Does it matter? Is it a simple matter of swapping the faucet cartridges back if it bothers me?
