The Moen Eva series encompasses single-handle lavatory faucets designed for bathroom sink installations. These faucets are characterized by a contemporary aesthetic, durable construction, and water-saving features. Available in various finishes, the Eva series aims to complement diverse bathroom styles. Documentation indicates a commitment to quality through a limited lifetime warranty and adherence to relevant industry standards. This article details the installation process, specifications, and operational characteristics of the Moen Eva series, specifically referencing model 6400 and the 66410.
Design and Construction
The Moen Eva faucets feature a single-handle design with a curved spout. The construction utilizes metal components, contributing to the faucet’s durability and longevity. The faucets are available in a variety of finishes, allowing for customization to match existing bathroom décor. Model 6400 includes an optional three-hole deck plate (escutcheon) for installations requiring coverage of additional mounting holes. Flexible supply lines with 3/8” fittings are included, designed for direct connection to supply stops.
Installation Procedures
Installation of the Moen Eva faucet is designed to be straightforward, though the provided documentation emphasizes the importance of following the included instructions. Specific steps, as outlined in available materials, include removing existing angle valves and installing the provided supply angle valves. For vessel sink applications, the use of a 1717 extension kit is recommended. The faucet is designed to be installed through a single hole with a minimum diameter of 1-1/8 inches. When installing, it is crucial to align markings on the ceramic body with corresponding marks on the floor to ensure proper positioning and prevent leaks. The documentation cautions against moving or rocking the faucet after alignment, as this could compromise the seal created by the putty.
