Non-Compliant Showerheads Introduction

Shower image 2Of concern to water providers and efficiency advocates are trends toward expanding residential shower systems and the sale of EPAct-non-compliant showerheads. The U.S. is faced with the prospect of increasing shower flow rates and water use within new homes as a consequence of these two trends. While such concerns were originally confined to new and remodeled “luxury” homes, it is evident that the trend is making its way into the average new home as well. Potentially non-compliant products include multiple showerheads in a single system, "rain" type shower systems with excessive flow rates, and shower “spas”. The extent to which these products are gaining market share is not known, but some generalized descriptions of the trend may be found in the following items.

Market Trends and Potential Loss of Savings

This short document provides selected quotations from various interior design trade publications on the topic of the “shower experience”. The reader must recognize that these trade publications and the articles therein are directed at the market for major remodeling and new construction projects. The terms used by the authors of the various statements may, to some extent, exaggerate the significance of these trends.

Lawrence Berkeley National Laboratory Showerhead Study (2005-2006)

Sponsored by Seattle Public Utilities, LBNL undertook to assess the impact upon residential water use of non-compliant and multiple-head shower systems. This study was a broad overview of the possible market penetration of such systems, the likely water consumption, and measures that might be taken to reduce water use in residential showers.
