A new shower will breathe life into your bathroom, and make bathing more enjoyable. Moen has a reputation for providing high-quality, reliable shower valves. We will show you how to install the Moen shower valve in this blog.

Following these instructions will allow you to install a shower system of professional quality and benefit from its reliability and efficiency.

  1. Gather All the Materials and Tools You Need: Before starting the installation process, it is important to collect all the materials and tools you need. The Moen shower kit includes an adjustable wrench or pipe cutter, a pipe deburring instrument, a soldering torch, flux, wire, solder, PTFE, tape and a screwdriver. To avoid any interruptions, make sure to have all of the necessary tools on hand.
  2. Before beginning any plumbing project, it is important to turn off water to the shower. Close the main water supply valve to your home to stop water flowing to the shower. Turning on the shower faucet to release pressure is another way to reduce the pressure.
  3. Remove Existing Shower Valves: In order to install a Moen replacement shower valve, it is necessary to remove the current valve. This involves disconnecting water supply pipes, removing mounting screws or brackets and carefully removing the old valve. Make a note of any existing connections. Also, make sure that you have sufficient space to install the new valve.
  4. Prepare the Pipes and Wall: It is essential that you prepare the pipes and wall before installing a new Moen Shower Valve. The area around the valve should be cleaned, including removing old sealant and any debris. Also, check the pipes for corrosion or damage. If necessary, deburr and cut the pipes in order to provide a clean, smooth surface on which the new connections can be made.
  5. Installing the Moen Shower Valve Follow the manufacturer’s instructions included with the Moen Shower Valve Kit to guide you. The valve is usually mounted to the wall with mounting brackets. Next, the cold and hot water supply lines are connected and the connections are secured using soldering or compression connectors. For a waterproof seal, apply PTFE to the threaded connectors.
  6. The Moen Shower Valve must be tested and adjusted after installation. Turn on the main water supply, and look for leaks near the connections. The temperature and water pressure should be adjusted to provide a consistent and comfortable flow. Adjust the valve using its built-in features and adjusting screw.
  7. Seal and Finish – After you’ve confirmed the Moen valve is functioning properly, seal and finish your installation. To create a waterproof seal, apply silicone or plumber’s putty on the valve trimplate to give it a polished finish. The trim plate can be mounted to the wall with the mounting brackets or screws provided.


Installing the Moen shower valve in your bathroom is an easy DIY project that will enhance your showering experience. You can easily tackle the installation by following the above step-by-step instructions and achieve professional results.

It is important to remember that you will need all the tools and materials needed, turn off the water, remove the old valve, clean the pipes and walls, install the Moen Shower Valve, adjust and test its functionality, seal the installation, and then finish it. Installing a Moen Shower Valve that is reliable and efficient will allow you to enjoy a refreshing shower every day.
