Truely SAFE products do not rely on the operator to observe variances to the
norm. They operate passively and in expected ways.
Sometimes a guest to your house might use the bathroom in the dark. Since
there is a universal assumption that cold is on the right (the original
designation was probably arbitrary but now it is a Standard) that person
might wash their hands only to find the wrong temperature.
If that is not a good enough reason, you would never get an inspector to
sign off and if you sold the house, it would show up prominently in the home
inspection report and likely result in your having to fix it then.
Some faucets do not have colored inserts but have engraved letters on
handles that cannot be exchanged, some people are even colorblind (imagine
that).
Nobody will arrest you for doing it but someone might sue you and win if
they are scalded. Intentionally reversing hot and cold would probably be
seen as negligent if it got that far.
I once stayed at a hotel that had the hot water hooked up to the toilet.
For what purpose I don't know, but it is luxurious to have your butt steamed
when you flush.
If you want fair treatment for lefties, try a faucet with one handle.
Post by prescotWhat does safety have to do with this? Hot water is indicated by red
tab on top of faucet blue for cold. What difference does it make?
