Exhibit 19.1

To Our Stockholders, Customers, and Employees

     Mueller's net income in the first quarter of 2007 was $18.9 million, or
51 cents per diluted share, which compares with $33.4 million, or 90 cents
per diluted share, for the same period of 2006.  First quarter net sales for
2007 were $609.8 million compared with $551.0 million in 2006.  The increase
in net sales was primarily attributable to acquired businesses.  The change
in net sales was also affected by the increased cost of copper, the
Company's principal raw material, which was largely passed through to
customers, offset by lower unit volume.  The COMEX average price of copper
was $2.70 per pound in the first quarter of 2007, which compares with $2.25
in the first quarter of 2006.

     Our Plumbing & Refrigeration segment posted operating earnings of $26.9
million on net sales of $370.0 million, which compares with prior year
earnings of $44.2 million on net sales of $386.9 million.  Operating margins
were affected by higher unit costs on lower production volume.  Net sales
for the Trading Group trended up but operating income was off slightly.
European results overall were profitable on the strength of our trading
businesses which continue to perform well.

     Our OEM segment posted operating earnings of $5.5 million during the
first quarter of 2007 on net sales of $243.7 million, which compares with
operating earnings of $11.0 million on net sales of $168.0 million for the
same period in 2006.  Our Chinese joint venture reported total operating
income of $1.7 million.

     We completed the acquisition of Extruded Metals, a brass rod mill, at
the end of February; their results are included in the OEM segment.  We are
presently rationalizing production with particular emphasis on casting
operations.  Operations have already been accretive to earnings; however,
there are opportunities for additional improvement as we integrate the brass
mill operations.

     The housing construction market is undergoing a much anticipated
correction which has dampened demand for certain of our products.  However,
we believe this market will improve later this year or early next year.  On
the other hand, the commercial construction market remains strong.

Very Truly Yours,

   /s/Harvey L. Karp                      /s/William D. O'Hagan
