plumbing backwards resized 600Many people have thought that their plumbing is backwards, meaning that the hot and cold water lines have been reversed. This is seldom the case.

\

In most cases the problem lies with how the fixture or fixtures were installed. A common location for the reversed water temperatures is at the shower, and involve a single handle that controls both the hot and cold water. In this case, the cartridge is reversed and needs to be rotated 180 degrees.

It’s the same solution for really any single handle fixture with the hot and cold reversed. A kitchen faucet is the same fix as the shower faucet. Remove the cover on the handle, unscrew the screw that holds the handle, and remove the handle. Rotate the stem 180 degrees and reassemble the handle. It should work fine.

If the kitchen faucet has two separate handles (one for cold and one for hot) and the temperatures are reversed, it is likely that the hot water supply line is connected to the cold side of the faucet and vise-versa. This is pretty hard to do as the hot is on the left and the cold is on the right. It is almost as if someone intentionally hooked up the water supply to the wrong sides.
