Can A Faucet Cartridge Be Put In Backwards?

You might be wondering why faucet cartridges are often installed backward.

This is because newer models of shower faucet cartridges are washerless, which means they can fit on either side. In fact, it's easier to install it backward, making it more confusing for those who are unfamiliar with the valve installation.

Older model faucets are threaded, making it easier to identify between hot and cold. The valves have stems with washers and threads that you can turn left and right to identify between hot and cold easily.

What Side Is Hot And Cold On Moen Shower Valve?

For Moen shower valves, the cold supply must be connected to the right and the hot water supply must be connected to the left. Remember:

  • Cold water supply = right valve
  • Hot water supply = left valve

If you're having trouble with inconsistent water temperature supply, such as only either hot or cold water coming out of the faucet, then there are several possible causes:

  • Debris blocking the balancing pool so the water is not moving freely
  • Lack of water pressure in the hot and cold water supply lines
  • The valve may need calibration

What to do:

  1. Check to ensure that the hot water system in your home is working
  2. Identify the model of your shower faucet. Procedures may vary depending on the model that you have installed. If you are unsure, you can find the model of your faucet in the Moen website's Find Your Product section.
  3. Once you find your product, you can refer to the instructions in this Moen troubleshooting guide.
