Moen Brass M-CORE 2/3 Function Transfer Valve with CC/IPS — U231CI

Overview

The Moen Brass M-CORE 2- or 3-Function Transfer Valve (U231CI) is a durable, adaptable centerpiece for modern showers. Crafted from solid brass and backed by Moen’s trusted warranty, this valve provides reliable control and a flexible foundation for customized shower experiences that can evolve with your design goals.

Flexible configuration for your shower design

Engineered to manage two or three showering devices, the valve switches between outlet counts via a simple cartridge modification. When you’re using two devices, outlet 3 must be capped (sold separately) to ensure balanced flow and a clean, focused shower experience. The setup supports a range of fixtures, from rainfall heads to handheld sprayers, enabling you to tailor the feel of your space.

Installation that saves time

An integrated mounting bracket anchors the valve directly to a wall brace, speeding up installation and delivering a tidy, professional result. This feature is especially valuable during remodels or in tight spaces where time and precision matter.

Included components and future-proofing

The valve ships with an independent 2- or 3-function diverter cartridge for straightforward configuration and dependable operation. The M-CORE family is designed to welcome future style or functional updates without removing the valve, keeping the core component relevant as your shower style evolves.

Plumbing compatibility and warranty

With CC/IPS connections and durable brass construction, the U231CI remains broadly compatible with standard fixtures. Moen backs this valve with a Limited Lifetime Warranty, offering long-term peace of mind for your investment.

Practical use cases

In a master bath, pair a rainfall head with a handheld or body sprays for a spa-like routine. In a family bathroom, configure two zones from a single control to accommodate different users. The valve’s adaptable design supports both new construction and remodel projects without locking you into a single path.
