           WATTS WATER TECHNOLOGIES REPORTS THIRD QUARTER 2007 RESULTS
                       AND ANNOUNCES RESTRUCTURING PROGRAM

      North Andover, MA...October 30, 2007. Watts Water Technologies, Inc.
(NYSE: WTS) today announced results for the third quarter ended September 30,
2007 and a global manufacturing restructuring program. Sales for the third
quarter of 2007 were $340.5 million, an increase of $15.4 million, or 5%,
compared to the third quarter of 2006. Net income for the third quarter of 2007
was $18.1 million, or $0.46 per share, compared to net income of $18.2 million,
or $0.55 per share, for the third quarter of 2006, which included a loss from
discontinued operations of $3.1 million, or ($0.09). Income from continuing
operations for the third quarter of 2007 decreased by $3.2 million, or 15%, to
$18.2 million, or $0.47 per share, compared to income from continuing operations
for the third quarter of 2006 of $21.3 million, or $0.65 per share. Results for
the third quarter of 2007 include an after-tax charge of $4.2 million, or
($0.11) per share, as part of the global restructuring program and charges for
discontinued product lines.

      Sales for the first nine months of 2007 were $1.04 billion, an increase of
$136.7 million, or 15%, compared to the first nine months of 2006. Net income
for the first nine months of 2007 was $55.9 million, or $1.43 per share,
compared to net income of $55.6 million, or $1.68 per share, for the first nine
months of 2006, which included a loss from discontinued operations of $3.4
million, or ($0.10) per share. Income from continuing operations for the first
nine months of 2007 decreased by $3.0 million, or 5%, to $55.9 million, or $1.43
per share, compared to income from continuing operations for the first nine
months of 2006 of $58.9 million, or $1.79 per share.

      In the third quarter, the Company undertook a review of certain product
lines and its overall manufacturing capacity. Based on that review, the Company
is initiating a global restructuring program that was approved by the Board of
Directors today. The Company is also discontinuing certain product lines. This
program is expected to include the shutdown of five manufacturing facilities and
the rightsizing of a sixth facility, including the relocation of the Company's
joint venture facility in China that was previously disclosed. The restructuring
program and charges for product line eliminations will include pre-tax charges
totaling approximately $13.4 million, including charges for severance ($4.3
million), relocation costs ($2.8 million) and other asset write-downs and
expected net losses on asset disposals ($2.0 million) and will result in the
elimination of approximately 330 positions worldwide. The product lines that are
being discontinued resulted in a pre-tax charge of $4.3 million. Total net after
tax charges for this program are expected to be approximately $9.7 million ($4.7
million non-cash), with costs being incurred through early 2010. The Company
expects to spend approximately $13.4 million in capital expenditures to
consolidate operations and will fund approximately $8.0 million of this amount
through proceeds from the sale of buildings and other assets being disposed of
as part of the restructuring program. Annual cash savings, net of tax, are



estimated to be $4.5 million, which we expect to fully realize by the second
half of 2009. The Company recorded non-cash after-tax charges of approximately
$4.2 million, or ($0.11) per share, in the third quarter of 2007 for inventory
product rationalization and other asset write-downs.

      In November 2006, the Company completed a public offering of 5.75 million
shares of Class A common stock and received net proceeds of approximately $219.0
million. The net proceeds are currently being invested in short-term securities,
which provided approximately $2.0 million and $5.8 million in after-tax income
in the third quarter and first nine months of 2007, respectively. The issuance
of an additional 5.75 million shares had a dilutive impact on earnings per share
of $0.03 per share and $0.09 per share in the third quarter and first nine
months of 2007, respectively, after considering the interest income from the net
proceeds. The Company had approximately $348.0 million in cash and cash
equivalents and short-term investments at September 30, 2007.

      Patrick S. O'Keefe, Chief Executive Officer, commented, "The goals of our
restructuring program are to rationalize our product offerings and to introduce
greater efficiencies and cost reductions into our manufacturing processes. We
plan to continue to review our operational footprint and we may consider further
actions in the future, if necessary."

      Commenting on third quarter sales, Mr. O'Keefe noted, "The sales increase
was achieved through favorable changes in foreign exchange rates of $9.7
million, or 3%, internal growth of $4.2 million, or 1%, and, to a lesser extent,
contributions from acquired companies.

      "Sales in our North American segment increased for the third quarter of
2007 by $4.0 million, or 2%, to $215.8 million compared to $211.8 million for
third quarter of 2006. This increase was achieved through internal sales growth
of $3.0 million, or 1%, and, to a lesser extent, from favorable foreign exchange
rates of $1.0 million associated with the strengthening of the Canadian dollar
versus the U.S. dollar.

      "Internal sales in our North American wholesale market for the third
quarter of 2007 increased 4% over the third quarter of 2006. This increase was
primarily due to price increases implemented to cover increases in the costs of
copper and other raw materials. Our North American home improvement retail
market sales declined 8% for the third quarter of 2007 compared to the third
quarter of 2006. This decrease was primarily due to our exiting markets in
certain lower margin product lines, partially offset by new product rollouts and
price increases.

      "We derived 32% of our total sales for the third quarter of 2007 from our
European segment. European sales increased $9.1 million, or 9%, to $110.5
million compared to $101.4 million for the third quarter of 2006. This increase
was achieved through favorable foreign exchange movement associated with the
strengthening of the euro versus the US dollar of $7.9 million, or 8%, and the
inclusion of an acquired company. Our internal growth in Europe was flat for the
third quarter as minor increases in wholesale sales were offset by reduced sales
into the OEM market.


      "China's segment sales in the third quarter of 2007 increased $2.2
million, or 19%, to $14.2 million compared to the third quarter of 2006. This
increase was achieved through internal growth of $1.5 million, or 13%, and
favorable foreign exchange rates associated with the yuan strengthening against
the U.S. dollar of $0.7 million, or 6%."

      Mr. O'Keefe concluded, "Our operating income for the third quarter of 2007
decreased by $6.3 million, or 17%, to $30.1 million as compared to $36.4 million
in the third quarter of 2006. Restructuring costs increased by $4.7 million, or
13%, and internal operating earnings decreased $3.2 million, or 8%, partially
offset by favorable foreign exchange movements, which contributed $1.4 million,
or 4%. Operating margins in the third quarter of 2007 decreased by approximately
240 basis points to 8.8% as compared to 11.2% in the third quarter of 2006.
Restructuring costs decreased operating margins in the third quarter of 2007 and
the third quarter of 2006 by 180 basis points and 40 basis points, respectively.
Compared to last year, our operating margins were impacted by increased
commodity costs, which were only partially offset by price increases."

      As previously discussed, the Company recorded a $4.2 million loss, net of
tax, or $0.11 per share, for restructuring and other costs in the third quarter
of 2007. The Company recorded a loss, net of tax, of $0.8 million, or $0.02 per
share, in the third quarter of 2006 for its manufacturing restructuring plan.
For the third quarter of 2006, these costs were primarily for severance costs
related to its European and Chinese restructuring plans.

      The Company recorded a loss, net of tax, of $4.5 million, or $0.12 per
share, in the first nine months of 2007 compared to income, net of tax, of $2.6
million, or $0.08 per share, in the first nine months of 2006 for its
manufacturing restructuring plan and product line eliminations. In the first
nine months of 2006, the Company benefited from an after-tax gain of
approximately $4.1 million, or $0.12 per share, related to the sale of a
building in Italy, which was recorded in the third quarter of 2006. This benefit
was offset by after-tax costs of approximately $1.5 million, or $0.04 per share,
primarily for severance costs related to the Company's European and Chinese
restructuring plans.
