TO OUR STOCKHOLDERS, CUSTOMERS AND EMPLOYEES

     We are pleased to report that Mueller had an outstanding third quarter.
The Company's earnings increased by 40 percent, compared with the same
quarter of 1998.

     Net earnings were $26.3 million, or 66 cents per diluted share, in the
third quarter of 1999, compared to $18.8 million, or 47 cents per diluted
share, in the same quarter of 1998.

     Mueller shipped 196.0 million pounds of product in the third quarter,
generating $287.9 million in net sales. This compares to 150.7 million
pounds shipped and $212.7 million in net sales in the comparable period of
1998.

     Mueller's manufacturing operations performed well during the quarter.
Copper tube enjoyed excellent results on favorable pricing and good volume.
Copper and plastic fittings continue to deliver solid sales and
profitability. Brass rod posted good volume and a modest rise in earnings
versus the same period last year.

     Despite achieving significant cost reductions, our Europe operations
continued to incur losses in the third quarter due to competitive pricing.
However, we are optimistic that pricing conditions will improve in the near
term.

     The Company has initiated a $10 million capital investment at our Port
Huron, Michigan brass rod mill. This investment, which is expected to be
completed near the end of 2000, will increase our casting capacity, improve
yield and reduce conversion costs.

     In addition, major capital improvements are under way at our Wynne,
Arkansas copper tube mill. Our casting facility in Fulton, Mississippi is
complete, enabling substantial savings in material costs under the right
market conditions.

     On August 30, 1999 Mueller repurchased 500,000 of its common
shares. The shares were bought for $29.15 each, slightly below the closing
price on the New York Stock Exchange on that date.

     Economic indicators continue to be positive for the U.S. economy and
housing industry. This bodes well for our business for the balance of 1999,
and into the year 2000.

Sincerely,

/S/HARVEY L. KARP                     /S/WILLIAM D. O'HAGAN
