Do the major plumbing fixture manufacturers have a uniform standard for
which way the handles on two knob fixtures should get turned to "open" them?
I got to wondering about that when we stayed at a hotel last weekend and
the two bathroom sinks in our room had fixtures which appeared to be
identical to those on six sinks in our home.
At home, every fixture operates the same; CCW to open the cold, and CW
to open the hot. That provides a natural feel when I go to open both at
the same time, my wrists twist in oposite directions. (Well, natural for
me at least, maybe a southpaw would feel different about it.)
But, the turning direction needed to open the hotel fixtures was
different on both of the sinks, one had both cold and hot turning CCW to
open, and the other was completely opposite to the ones in our home, CW
to open the cold and CCW for the hot.
Not a big whoop, but I got "fooled" every time I went to use a sink for
those two days, and it took more fiddling to adjust the water
temperature that I'm used to.
I put it down to indifferent installation or maintenance with someone
swapping parts or not having the right parts and using what was on hand,
which got me wondering what the fixture manufacturers' position on the
Jeff (Who clearly has way too much time on his hands today...)
P.S. Is the opening direction opposite below the equator? <G>
That sounds to me like the installer reversed the hot and cold inlets,
but what do I know, maybe single handled shower valves are available in
two types to make it easier to plumb them in when they are on opposite
sides of the same wall?
This reminds me of something I did several years ago, as a prank. My
elderly parents kept asking me to fix the drippy faucet on their
bathroom sink. I went there to fix it, and while I was there, I
realized it was April 1 (April fools day). I couldn't resist. I
swapped the supply hoses, putting the hot on the right and cold on the
left. Then I switched the little tabs that say H an C, so the H one
was on the hot side and C on the cold. Then I left and wert home to
wait for the phone to ring. Sure enough, I wasn't home 5 minutes when
mom calls and says "There's something different about the sink", and
she goes on trying to explain. I am trying not to laugh. I tell her
to go turn the one with the H on it, and ask her if it's hot. She
comes back to the phone and says "yes". I tell her to do the same for
the C and see if it's cold. She gets bacjk and says "yes". I said
"so what's the problem". She said "something just seems different,
but like you said, it's right". We get off the phone. Sure enough,
20 minutes later she is on the phone again. "Dad said the faucets are
backward, is that possible". I just played along and kept saying "the
H turns on the hot, right? She says "yes", I say "so what's the
Several hours later, dad calls and insists the faucets are backwards.
I just played along and did the same thing as I had done with mom. An
hour later, after discussing the faucet nearly the whole time, I told
him to put mom on the phone. She gets on, and I said "guess what.....
APRIL FOOL. Now tell dad......
We all got a good laugh out of that. However, I told them I could not
reverse it until April 2.

As far as I know the standard is for them to open the
way yours do at home. CW for hot, CCW for cold. I
thing they usually come from the manufacturer that way.
For some faucets, particularly ones with a swivel
spigot, it is quite easy to get them in backward. I did
in the kitchen. I fixed that easily enough by swapping
As far as have them both turning the same way. That is
probably a repair job. One time I needed a new
cartridge for the hot water side. I went to the store
and bought a new cartridge, which was marked for hot or
cold use. When I got home it was a cold water
cartridge, and turned the wrong way for hot. I took it
back and went to a plumbing supply house and got the
right one. Apparently, in order to reduce their stock a
lot of suppliers stock just one, which will work, but
will turn the wrong way for one side. This of course
makes things work all wrong.
I think the rule is, Round knobs open CCW, Lever knobs depend on the
side, and open with the lever pulled toward the user.
If a lever knob is changed to a round knob, then the CCW no longer
works because it did not work for the lever.
I'm surprised no one has mentioned this (yet). --Phil

.. . . despite the near-universal agreement that clockwise rotation of a
rotary control (or upward or rightward movement of a slider) should
INcrease whatever it is controlling (volume, frequency, temperature,
etc.) and counterclockwise rotation should DEcrease whatever it is

that in both UK and Australia "taps" ("faucets" to Americans) opened by
counterclockwise rotation (as in USA) but their position was reversed:
cold on the left, hot on the right.

I replumbed my basement years back. Somehow I got the hot/cold piping
to an old laundry tub reversed. 'No problem' sez I. 'I only use it
occasionally and will remember'. Nope. After getting it wrong several
times I finally bit the bullet and crossed the pipes coming out of the
ceiling. Ugly looking mess but at least it is back to standard.
Wasn't room to re-do it in the ceiling.
