Which side of the kitchen faucet does the red (hot) ceramic
disc cartridge stem go on?
Hot water should only flow from the left side of all faucets.
However, in some cases, the water was not plumbed correctly when your home was built. To fix the problem,
reverse the faucet's water lines from the shut-off valves to the faucet. This should be a simple fix, but if
you are not comfortable working on the plumbing, a plumber or handyman will do. The whole job will only take an
hour or less.
