                 WATTS INDUSTRIES REPORTS FIRST QUARTER RESULTS

      North Andover, MA...May 6, 2003. Watts Industries, Inc. (NYSE Symbol
"WTS") today announced earnings for the quarter ended March 31, 2003. For the
three months ended March 31, 2003, sales were $165,692,000, an increase of
$22,372,000, or 16% from the comparable period last year. Net income for the
three months ended March 31, 2003, was $6,610,000 or $0.24 per share, which
includes a net loss from discontinued operations of $2,326,000, or $0.09 per
share, compared to net income of $8,056,000, or $0.30 per share, for the quarter
ended March 31, 2002. Income from continuing operations for the quarter ended
March 31, 2003, was $8,936,000 or $.33 per share, which includes $277,000 of
after-tax costs, or $.01 per share, incurred for the previously announced
manufacturing restructuring plan. Income from continuing operations for the
three months ended March 31, 2002, was $8,056,000, or $.30 per share, which
includes $555,000 of after-tax costs, or $.02 per share, incurred for the
manufacturing restructuring plan. Excluding the manufacturing restructuring
costs in both periods, income from continuing operations increased 7% to
$9,213,000 for the three months ended March 31, 2003, compared to $8,611,000 for
the three months ended March 31, 2002. Excluding the manufacturing restructuring
plan expenses, earnings per share from continuing operations for the quarter
ended March 31, 2003, exceeded consensus earnings estimates by $.01 per share.
Please refer to the financial information included at the end of this press
release for a reconciliation of adjusted income from continuing operations to
net income.

      Patrick S. O'Keefe, Chief Executive Officer, commented, "We are pleased
with a strong showing for the quarterly results, despite some weakness
experienced in our core North American wholesale market. We continue to show
gains in our sales into the North American home improvement retail market with
an internal growth rate of 18% for the quarter over the first quarter of 2002.
Sales into the North American retail market were $33,892,000 for the quarter
ended March 31, 2003. We are pleased that we achieved sales growth in all of our
brands into the North American retail markets during our first quarter. Our
sales into the North American wholesale market declined 3% compared to the
quarter ended March 31, 2002, primarily due to the weak commercial construction
market. However due to our strong showing on the retail



side, our overall sales in the North American market had an internal growth rate
of 3% for the quarter over the comparable period in 2002."

      Mr. O'Keefe continued, "We derived 29% of our total revenue for the
quarter ended March 31, 2003, from Europe compared to 22% in the quarter ended
March 31, 2002. Sales in Europe, in local currency, for the three months ended
March 31, 2003, increased 25% compared to the comparable period last year due to
the inclusion of the acquisitions consummated during 2002. On July 15, 2002, we
acquired ADEV Electronic SA located in Rosieres, France, and its closely
affiliated distributor, E.K. Eminent in Gothenburg, Sweden, and on July 29,
2002, we acquired F&R Foerster Rothmann GmbH located in Neuenburg am Rhein,
Germany. These European acquisitions contributed $8,728,000 of revenue during
the quarter. The euro has appreciated approximately 24% versus the quarter ended
March 31, 2002, and had a positive impact on sales of $7,655,000, and on
earnings of $.02 per share in the quarter ended March 31, 2003. Excluding the
effect of acquisitions and the appreciation of the euro, sales into our European
market increased 3% in the quarter, as compared to the first quarter of last
year, primarily attributable to increased sales to our OEM customers. Sales into
the Chinese market increased $2,000,000 for the quarter ended March 31, 2003,
compared to the comparable period last year, due to the establishment of our
joint venture in March 2002 with the Cheng Guan Metal Hose Factory."

      During the quarter ended March 31, 2003, an offer was made for $13 million
($11 million from us and $2 million from Tyco), plus payment of Relator's
attorney's fees, to settle the claims of the three cities (Santa Monica, San
Francisco and East Bay Municipal Water District) in the James Jones litigation
chosen by the Relator as having the strongest claims. This offer included the
Relator's statutory share. The three cities have indicated through their
attorney that the $13 million is acceptable to them, but the Relator's
attorney's fee issue has not been resolved. The offer is subject to a written
Memorandum of Understanding between the Relator and the defendants, a written
Sharing Agreement for the defendants and an approval by the California Superior
Court. It is possible that the written settlement agreements or the court
approval may not be obtained. As a result of this offer, the Company recorded an
after tax charge of $2,326,000, or ($0.09) per common share on a diluted basis,
in the quarter ended March 31, 2003. This charge is reported as a loss from
discontinued operations.

      To supplement our unaudited consolidated financial statements presented on
a GAAP basis, we sometimes use non-GAAP measures of net income, net income per
share, income from continuing operations or income from continuing operations
per share that we believe are appropriate to enhance an overall understanding of
our historical financial performance and future prospects. The non-GAAP results,
which are adjusted to exclude certain costs, expenses, gains and losses from the
comparable GAAP measures, are an indication of our baseline performance before
gains, losses or other charges that are considered by management to be outside
of our core operating results. These non-GAAP results are among the primary
indicators management uses as a basis for evaluating our financial performance
as well as for forecasting of future periods. For these reasons, management
believes these non-GAAP measures can be useful to investors, potential investors
and others. The presentation of this additional information is not



meant to be considered in isolation or as a substitute for net income or income
per share prepared in accordance with GAAP.

      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 Exchange Commission and other reports Watts files from time to time
with the Securities and Exchange Commission. Watts does not intend to and
