             WATTS WATER TECHNOLOGIES REPORTS THIRD QUARTER RESULTS


      North Andover, MA...November 4, 2003. Watts Water Technologies, Inc. (NYSE
Symbol "WTS") today announced results for the quarter ended September 30, 2003.
For the three-month period ended September 30, 2003, sales were $175,509,000, an
increase of $15,698,000, or 10%, from the three-month period ended September 30,
2002. Net income for the three-month period ended September 30, 2003, was
$8,905,000, or $0.32 per share, which includes a net loss from discontinued
operations of $114,000, compared to net income of $8,773,000, or $0.32 per
share, for the three-month period ended September 30, 2002. Income from
continuing operations for the three-month period ended September 30, 2003, was
$9,019,000, or $0.33 per share, compared to income from continuing operations
for the three-month period ended September 30, 2002 of $8,773,000, or $.32 per
share, which includes $398,000 of after-tax costs, or $0.02 per share, incurred
for our manufacturing restructuring plan.

      Sales for the nine-month period ended September 30, 2003, increased 13% to
$514,713,000 from $454,636,000 for the nine-month period ended September 30,
2002. Net income for the nine-month period ended September 30, 2003 was
$23,621,000, or $0.86 per share, which includes a net loss from discontinued
operations of $3,014,000, or $0.11 per share, compared to $25,462,000, or $0.94
per share, for the nine-month period ended September 30, 2002. Income from
continuing operations increased $1,173,000, or 5% to $26,635,000 for the
nine-month period ended September 30, 2003 compared to $25,462,000 for the
nine-month period ended September 30, 2002.

      Excluding the costs incurred for our manufacturing restructuring plan from
both periods, income from continuing operations increased $383,000, or 1%, to
$27,275,000, or $0.99 per share, for the nine-month period ended September 30,
2003 compared to $26,892,000, or $0.99 per share, for the nine-month period
ended September 30, 2002. Please refer to the table included at the end of this
press release for a reconciliation of reported net income to adjusted income
from continuing operations.

      Patrick S. O'Keefe, Chief Executive Officer, commented, "We are pleased
with our North American and European results for the third quarter of 2003.
These strong results were partially offset by inventory write-downs and other
net adjustments in our Chinese segment. Our overall increase in sales was
achieved by the change in foreign exchange rates, organic growth and
contributions from acquired companies. On a consolidated basis, the change in
foreign



exchange rates for the three-month period ended September 30, 2003 increased our
sales by $7,509,000, over the three-month period ended September 30, 2002, due
primarily to the strengthening of the euro versus the U.S. dollar. On a
consolidated basis we achieved an organic growth rate of 4% for the three-month
period ended September 30, 2003 over three-month period ended September 30,
2002, which represents $6,523,000 of increased sales. Our acquisition program
contributed $1,666,000 of sales for the three-month period ended September 30,
2003, derived from the recent acquisitions of Martin Orgee and Giuliani Anello,
both European based companies."

      Mr. O'Keefe continued, "Our North American segment had an increase in
sales for the three-month period ended September 30, 2003 of 6% to $121,001,000
compared to $114,136,000 for the three-month period ended September 30, 2002.
This increase in North American sales over the three-month period ended
September 30, 2002 was achieved through the combination of organic sales growth
of 5%, or $5,825,000, and favorable foreign exchange rates associated with the
strengthening of the Canadian dollar versus the U.S. dollar, which had the
effect of increasing sales by $1,041,000. Sales into the North American home
improvement retail market for the three-month period ended September 30, 2003
increased by 11% with total sales of $33,468,000 compared to $30,055,000 for the
three-month period ended September 30, 2002. Sales into the North American
wholesale market for the three-month period ended September 30, 2003 increased
4% to $87,533,000 compared to $84,081,000 for the three-month period ended
September 30, 2002. This increase was primarily due to improved sales of our
well-known backflow prevention line."

      Mr. O'Keefe continued, "We derived 29% of our total sales for the
three-month period ended September 30, 2003 from Europe compared to 24% in the
three-month period ended September 30, 2002. Sales in Europe for the three-month
period ended September 30, 2003 increased 29% compared to the three-month period
ended September 30, 2002, due to the favorable change in foreign exchange rates,
an internal growth rate of 9%, and the inclusion of acquisitions consummated
during 2003. On April 18, 2003 we acquired Martin Orgee U.K. Ltd. located in
Kidderminster, West Midlands, United Kingdom, and on July 30, 2003, we acquired
Giuliani Anello S.r.l. located in Bologna, Italy. These European acquisitions
contributed $1,666,000 of sales during the three-month period ended September
30, 2003. The euro has appreciated approximately 15% versus the three-month
period ended September 30, 2002 resulting in a positive impact on European sales
of $6,468,000 and on income of $0.02 per share in the three-month period ended
September 30, 2003.

      Mr. O'Keefe also commented, "As we discussed at the end of our second
quarter of 2003, we had experienced a delay in production at our new
wholly-owned manufacturing plant in Tianjin, China. We have experienced some
increase in the production levels from this factory during the third quarter of
2003, however the under-absorption of manufacturing costs caused by this delay
had an adverse impact of $.02 per share in the three-month period ended
September 30, 2003. The results of the three-month period ended September 30,
2003 also include the



impact of inventory write-downs and other net adjustments at our TWT joint
venture in Tianjin which reduced income by $0.03 per share."

      During the three-month period ended September 30, 2003, the Company
recorded an after-tax charge of $114,000, or $0.01 per share, to discontinued
operations. This charge is primarily attributable to legal fees associated with
the James Jones litigation that is now treated as a discontinued operation.

      On July 30, 2003 a wholly-owned subsidiary of the Company acquired
Giuliani Anello located in Bologna, Italy for approximately $12 million in cash.
Giuliani Anello manufactures and distributes valves and filters utilized in
heating applications including strainer filters, solenoid valves, flow stop
valves, stainless steel water filter elements and steam cleaning filters.
Giuliani Anello's annual sales, prior to the acquisition, were $7 million at the
exchange rate in effect as of the closing date.

      To supplement our unaudited consolidated financial statements presented on
a generally accepted accounting principles (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
Water Technologies' 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
