There are two types of taps in my house, and both of them are suitable for cold, hot or mixed water.
The difference is one kind has ONE knob and the other kind has TWO.
The one-knob tap (for kitchen) controls hot and cold water together. When the knob is rotated to the left, hot water flows out, meanwhile right means cold water, and center means mixed water.
The two-knob tap (for bathroom) controls hot and cold water separately. One is for hot water and the other is for cold water.
OK, so are there two specific terms or phrases for two kinds of taps?
Thanks a lot.
