          WATTS WATER TECHNOLOGIES REPORTS FOURTH QUARTER 2007 RESULTS

      North Andover, MA...February 12, 2008. Watts Water Technologies, Inc.
(NYSE: WTS) today announced results for the fourth quarter ended December 31,
2007. Sales for the fourth quarter of 2007 were $345.3 million, an increase of
$14.8 million, or 4%, compared to the fourth quarter of 2006. Net income for the
fourth quarter of 2007 was $21.5 million, or $0.55 per share, compared to net
income of $18.1 million, or $0.51 per share, for the fourth quarter of 2006.
Income from continuing operations for the fourth quarter of 2007 increased by
$3.6 million, or 20%, to $21.7 million, or $0.56 per share, compared to income
from continuing operations for the fourth quarter of 2006 of $18.1 million, or
$0.51 per share.

      Results for the fourth quarter of 2007 include an after-tax charge of $0.6
million, or $0.02 per share, as part of our previously announced global
restructuring program and product line discontinuances, compared to an after-tax
charge of $1.1 million, or $0.03 per share, for the fourth quarter of 2006.

      Sales for the year ended December 31, 2007 were $1.382 billion, an
increase of $151.5 million, or 12%, compared to the year ended December 31,
2006. Net income for the year ended December 31, 2007 was $77.4 million, or
$1.99 per share, compared to net income of $73.7 million, or $2.19 per share,
for the year ended December 31, 2006, which included a loss from discontinued
operations of $3.4 million, or ($0.10) per share. Income from continuing
operations for the year ended December 31, 2007 increased by $0.5 million, or
1%, to $77.6 million.

      For the year ended December 31, 2007, the Company recorded an after-tax
charge of $5.1 million, or $0.13 per share, for product line discontinuances and
restructuring charges, compared to income, net of tax, of $1.5 million, or $0.04
per share, for the year ended December 31, 2006. The charge in 2007 relates
primarily to product line discontinuances, other asset write-downs and
accelerated depreciation. In 2006, gains from the sale of two facilities in
Italy were partially offset by costs incurred for severance programs in Europe
and China and accelerated depreciation in China.

      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 $1.4 million and $7.1 million in after-tax income
in the fourth quarter and the year ended December 31, 2007, respectively. The


issuance of an additional 5.75 million shares had a dilutive impact on earnings
per share of $0.02 per share and $0.11 per share in the fourth quarter and the
year ended December 31, 2007, respectively, after considering the interest
income from the net proceeds. The Company had approximately $329.3 million in
cash and cash equivalents and short-term investments at December 31, 2007.

      In November 2007, the Company's Board of Directors authorized the
repurchase of up to 3.0 million shares of the Company's Class A common stock. As
of February 8, 2008, the Company has repurchased approximately 2.1 million
shares at a total cost of $58.1 million.

      Patrick S. O'Keefe, Chief Executive Officer, commented, "The fourth
quarter sales increase was achieved through favorable changes in foreign
exchange rates of $15.8 million, or 5%, and contributions from an acquisition of
$2.0 million, or 1%, partially offset by a decrease in organic sales of $3.0
million, or 1%.

      "Sales in our North American segment increased for the fourth quarter of
2007 by $7.7 million, or 4%, to $212.4 million compared to $204.7 million for
fourth quarter of 2006. This increase was achieved through internal sales growth
of $3.0 million, or 2%, from favorable foreign exchange movements of $2.7
million, or 1%, associated with the strengthening of the Canadian dollar versus
the U.S. dollar and contributions from an acquisition of $2.0 million, or 1%.

      "Organic sales in our North American wholesale market for the fourth
quarter of 2007 increased 3% over the fourth 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 5% for the fourth quarter of 2007 compared to the fourth
quarter of 2006. This decrease was primarily due to our exiting certain lower
margin product lines, partially offset by price increases and new product
rollouts.

      "We derived 34% of our total sales for the fourth quarter of 2007 from our
European segment. European sales increased $8.3 million, or 8%, to $118.3
million compared to $110.0 million for the fourth quarter of 2006. This increase
was achieved through favorable foreign exchange movements associated with the
strengthening of the euro versus the US dollar of $12.3 million, or 11%. We
experienced a decline in organic sales in Europe for the fourth quarter of $4.0
million, or 3%, due to decreased sales primarily in Germany.

      "Sales in our China segment in the fourth quarter of 2007 decreased $1.2
million, or 8%, to $14.6 million compared to the fourth quarter of 2006. This
included a decrease in organic sales of $2.0 million, or 13%, partially offset
by favorable foreign exchange movements associated with the strengthening of the
yuan against the U.S. dollar of $0.8 million, or 5%."


      Mr. O'Keefe concluded, "Our operating income for the fourth quarter of
2007 increased by $6.1 million, or 21%, to $34.9 million as compared to $28.8
million in the fourth quarter of 2006. Organic operating earnings increased $2.5
million, or 9%, restructuring costs decreased by $2.3 million, or 8%, and
favorable foreign exchange movements contributed $2.0 million, or 7%, and were
partially offset by the amortization of certain costs associated with the
acquisition of Topway Global, Inc. acquired in November 2007 of $0.7 million, or
3%. Operating margins in the fourth quarter of 2007 increased by approximately
140 basis points to 10.1% as compared to 8.7% in the fourth quarter of 2006.
Restructuring costs decreased operating margins in the fourth quarter of 2007
and the fourth quarter of 2006 by approximately 20 basis points and 100 basis
points, respectively. Compared to last year, our operating margins were
favorably impacted by price increases, product mix and leveraging of selling,
general and administrative expenses."

      The Company generated $91.7 million in net cash provided from continuing
operations for the year ended December 31, 2007 as compared to $83.0 million for
the year ended December 31, 2006. Free cash flow (a non-GAAP financial measure)
for the year ended December 31, 2007 was $54.5 million compared with $70.2
million for the year ended December 31, 2006. Included in 2006 is $31.9 million
for the sale of two buildings in Europe. Please refer to Table 1 at the end of
this press release for a reconciliation of net cash provided by continuing
operations to free cash flow. The Company's net debt to capitalization ratio (a
non-GAAP financial measure) increased to 13% for the year ended December 31,
2007 from 11% in the prior year. Please refer to Table 2 at the end of this
press release for a reconciliation of long-term debt (including current portion)
to net debt and net debt to capitalization ratio.

      To supplement our consolidated financial statements presented in
accordance with generally accepted accounting principles (GAAP), we sometimes
use non-GAAP financial measures, such as free cash flow and the net debt to
capitalization ratio, that we believe are appropriate to enhance an overall
understanding of our historical financial performance and future prospects. The
non-GAAP items, which are adjusted to exclude certain cash inflows and outlays,
and include only certain balance sheet accounts from the comparable GAAP
measures, are an indication of our performance in cash flow generation and also
provide an indication of the Company's relative balance sheet leverage to other
industrial manufacturing companies. These non-GAAP financial measures are among
the primary indicators management uses as a basis for evaluating our cash flow
generation and our capitalization structure. For these reasons, management
believes these non-GAAP financial 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 changes in cash and
cash equivalents prepared in accordance with GAAP.
