Mueller Water Products Amends Credit Facility

June 18, 2009

ATLANTA, June 18 /PRNewswire-FirstCall/ -- Mueller Water Products, Inc. (NYSE: MWA) announced today that it has amended its Credit Facility dated as of May 24, 2007. The amended $765.7 million Credit Facility includes a $200.0 million revolving line of credit which remains undrawn and is effective June 18, 2009. The amended Credit Facility includes revised and new financial covenant ratios through its remaining life, among other changed terms.

"We are very pleased to have completed this amendment, which was driven by the need for covenant ratio relief and not by liquidity issues," said Gregory E. Hyland, chairman, president and chief executive officer of Mueller Water Products. "This amendment allows us to remain focused on meeting our customers' needs during this economic recession while continuing to improve our market-leading positions in the water infrastructure and flow control industries. We appreciate the relationship we have with our lenders and their support of this amendment."

Additional information concerning the revised financial covenant ratios, pricing and other changes to the Credit Facility, and a copy of the amendment to the Credit Facility, can be found in the Company's Form 8-K, to be filed with the Securities and Exchange Commission.
