TO OUR STOCKHOLDERS, CUSTOMERS, AND EMPLOYEES

     The first quarter of 2001 was a "good news - bad news" story for
Mueller.  The bad news was that sales and earnings declined as the overall
economy slowed.  Net earnings were $15.5 million, or 42 cents per diluted
share, compared with 69 cents per diluted share for the same quarter last
year.  Also, net sales for the first quarter were $276.6 million compared
with sales of $309.3 million for the first quarter of 2000.

     The good news was that Mueller remained solidly profitable with
excellent cash flow and a strong balance sheet that continued to
strengthen.  Moreover, we are optimistic that business will improve in the
second quarter.  Our optimism is fueled by several factors:

  * the severe winter weather (which we had been spared for several years)
    constrained construction activity, but it is now behind us;

  * the inventory adjustments made by our customers are now largely complete;

  * significant steps have been taken to reduce our costs; and,

  * the construction industry has shown remarkable resiliency, due, in part,
    to declining mortgage rates

     The theme of Mueller's Annual Report this year is "looking ahead."  We
selected this theme because it reflects our strategy of building basic
shareholder value over the long term rather than embracing short-term
palliatives.  This strategy has succeeded over the past decade and we are
convinced it is the best strategy going forward.

     In 2000, Mueller invested over $63 million in capital improvement
projects.  We expect to invest approximately $50 million during 2001, of
which approximately $20 million relates to the modernization of our European
tube mills.  By year-end this project will be completed and our conversion
costs in Europe should be sharply reduced.  We anticipate that capital
expenditures in future years will be restrained, as we focus on realizing
the full potential of the many projects we have implemented in recent years.

     Our Annual Stockholders' Meeting will be held at Mueller's headquarters
in Memphis, Tennessee on May 10, 2001.  You should have already received the
notice of meeting, as well as proxy material and the 2000 Annual Report.  We
hope you can attend, but if you cannot, we urge you to sign and return your
proxy card.

Sincerely,

/S/HARVEY L. KARP
