                        WATTS INDUSTRIES REVISES EARNINGS

      North Andover, MA...March 26, 2003. On February 12, 2003, Watts
Industries, Inc. (NYSE Symbol "WTS") issued a press release, which disclosed its
earnings for the three and twelve months ended December 31, 2002. Subsequent to
February 12, 2003, management learned of unauthorized payments pertaining to the
Company's joint venture located in Tianjin, China, which was established in
1994. We conducted an independent investigation, which determined that
unauthorized payments and cash receipts had been made utilizing an account that
was established to fund certain employee benefit programs. These transactions
had not been properly recorded in our joint venture's results of operations.
While this activity occurred over an eight-year period, the Company recorded a
charge as of December 31, 2002 to correct and record all identified items
impacting the results of operations. Therefore, the Company has revised its
previously reported earnings for the twelve months ended December 31, 2002 from
$1.22 diluted earnings per share to $1.21 diluted earnings per share, and for
the three months ended December 31, 2002, from $.28 diluted earnings per share
to $.26 diluted earnings per share. The accompanying financial statements
reflect these revised earnings.

      On March 26, 2003, the Company is filing its annual report on Form 10-K,
which will contain a complete description of these revisions.

      This Press Release may include statements which are not historical facts
and are considered forward-looking within the meaning of the Private Securities
Litigation Reform Act of 1995. These forward-looking statements reflect Watts
Industries' current views about future results of operations and other
forward-looking information. You should not rely on forward-looking statements
because Watts' actual results may differ materially from those indicated by
these forward-looking statements as a result of a number of important factors.
These factors include, but are not limited to, the following: loss of market
share through competition, introduction of competing products by other
companies, pressure on prices from competitors, suppliers, and/or customers,
failure or delay in developing new products, lack of acceptance of new products,
failure to manufacture products that meet required performance and safety
standards, foreign exchange fluctuations, cyclicality of industries, such as
plumbing and heating wholesalers and home improvement retailers, in which the
Company markets certain of its products, reductions in the supply of raw

materials, increases in the prices of raw materials, economic factors, such as
the levels of housing starts and remodeling, impacting the markets where the
Company's products are sold, manufactured, or marketed, environmental compliance
costs, product liability risks, the results and timing of the Company's
manufacturing restructuring plan, changes in the status of current litigation,
including the James Jones case, and other risks and uncertainties discussed
under the heading "Certain Factors Affecting Future Results" in Watts' Annual
Report on Form 10-K for the year ended December 31, 2002 filed with the
Securities and Exchange Commission and other reports Watts files from time to
time with the Securities and Exchange Commission. Watts does not intend to and
undertakes no duty to update the information contained in this Press Release.
