The Moen Banbury 82910 series is a single-handle tub/shower valve designed for residential use. It features a pressure balancing cycle valve and an adjustable temperature limit stop. The valve includes the valve itself, a tub spout, a showerhead, an arm, and a flange. This article details the specifications, operation, and maintenance procedures for this valve, based on available documentation.
Specifications
The Moen Banbury 82910 series valve has several key specifications. The construction utilizes metal with various finishes, identified by a suffix. Connections are 1/2" IPS (inches per pound square) and the valve utilizes a 1222 cartridge design. The cartridge is constructed from nonmetallic/nonferrous and stainless steel materials and is suitable for back-to-back installations.
Critical dimensions for installation are provided in the documentation. The finished wall line should be 4-1/2" from the center of the valve. The distance between centers is 2-3/4". The valve’s nominal diameter is 1-3/8", with a maximum shower arm length of 45" or 48" and a maximum tub spout length of 32". The wall opening diameter is 1-1/2" maximum. The valve is designed for a maximum wall thickness of 2-1/2".
The showerhead is limited to a flow rate of 2.5 gpm (gallons per minute), or 9.5 L/min (liters per minute). The valve operates with a lever-style handle that rotates counterclockwise through a 270-degree arc, with the off position at 6 o'clock and maximum hot water at the 9 o'clock position. Shut off is achieved by rotating the handle clockwise.
Operation and Features
The Banbury 82910 series valve incorporates a pressure balancing mechanism designed to maintain a selected discharge temperature within ± 2°F. This feature helps prevent scalding or sudden temperature fluctuations during changes in water pressure. An adjustable temperature limit stop is also included, allowing users to control the maximum hot water temperature.
The valve’s operation is centered around the 1222 cartridge. The documentation notes that the cartridge is unequalled in quality and reliability. The handle’s movement controls the water flow and temperature. The 270-degree arc of rotation provides a wide range of control.
Installation Considerations
While detailed installation instructions are not fully provided in the source documents, critical dimensions are specified for proper placement. The documentation emphasizes the importance of ensuring proper connections, specifically 1/2" IPS connections. The valve is designed to accommodate back-to-back installations due to the cartridge design.
Maintenance and Troubleshooting
Maintaining Moen shower fixtures, including the Banbury 82910 series, can be achieved using similar cleaning tips recommended for Moen faucets. However, a specific issue addressed in the documentation is uneven spray from the showerhead. This is often caused by mineral deposits clogging the showerhead.
To address a clogged showerhead, the swivel ball nut should be unscrewed using a wrench or channel-type pliers. The documentation advises wrapping the jaws of the tool with masking tape or using a cloth to prevent scratching the finish.
The documentation also addresses potential issues with valves becoming “frozen” from lack of use. These valves, located both below the sink and in the basement, should be checked regularly. Applying a wrench to the control handle can free up the valve, turning clockwise to close it. Caution is advised when applying the wrench to avoid breaking off the control handle.
Cartridge Replacement
The documentation provides instructions for replacing the cartridge in two-handle faucets, but does not specifically detail the process for the Banbury 82910 single-handle valve. However, the general principles are outlined. The process involves turning off the water supply and draining any remaining water from the tap. The handle and any coverings on the valve body are then removed. The documentation states that the flat part of the D-shaped top of the 1224 cartridge must line up with the cartridge tab, with the outlet port facing the spout and the cartridge tab on the opposite side.
Warranty Information
Moen products are covered under a Limited Lifetime Warranty. The documentation states that Moen products are manufactured under the highest standards of quality and workmanship. The full warranty details are included in a separate sheet found in the homeowner’s packet.

Conclusion
The Moen Banbury 82910 series tub/shower valve is a pressure-balancing valve designed for reliable performance and temperature control. Its specifications, including dimensions and flow rates, are clearly defined. Regular maintenance, such as cleaning the showerhead and checking supply valves, can ensure long-term functionality. The availability of replacement parts and a Limited Lifetime Warranty further contribute to the product’s value.
