Easy Installation for your Plumber

​​​​​​Valve installation is an extremely technical and tremendously complex job that requires a lot of time and a high level of plumbing skill. It can be tricky and time consuming. The M-CORE valve system is making this process a whole lot easier for pro installers by allowing them to quickly and efficiently install a valve that will allow for adaptable functionality once it has been plumbed. The valve’s features were designed to reduce time and labor costs, without sacrificing work quality.

The M-CORE system also features an integrated mounting bracket that secures the valve directly to a brace, streamlining the installation process. It offers a quicker temperature limit stop adjustment process, and the integrated test plug allows installers to easily flush and test the system without having to remove or install the cartridge. M-CORE mixing and transfer valves also are available in several inlet and outlet plumbing options to meet the needs of the installers.
