          WATTS WATER TECHNOLOGIES REPORTS FOURTH QUARTER 2006 RESULTS

      North Andover, MA...February 13, 2007. Watts Water Technologies, Inc.
(NYSE: WTS) today announced results for the fourth quarter ended December 31
2006. Sales were $330,515,000, an increase of $86,108,000, or 35%, compared to
the fourth quarter of 2005. Net income for the fourth quarter of 2006 was
$18,140,000, or $0.51 per share, compared to net income of $14,960,000, or $0.45
per share, which included a loss from discontinued operations of $236,000, or
$0.01 per share, for the fourth quarter of 2005. Income from continuing
operations for the fourth quarter of 2006 increased by $2,943,000, or 19%, to
$18,139,000, or $0.51 per share, compared to income from continuing operations
for the fourth quarter of 2005 of $15,196,000, or $0.46 per share.

      Costs incurred related to the Company's manufacturing and restructuring
plan, net of tax, in the fourth quarters of 2006 and 2005 were $1,106,000, or
$0.03 per share, and $241,000, or $0.01 per share, respectively. Costs for
severance programs in both Europe and China and accelerated depreciation on
certain assets in China were partially offset by a gain from a building sale in
Italy in the fourth quarter of 2006. Costs incurred in 2005 primarily relate to
severance costs in Europe.

      As a result of the Company's November 2006 stock offering of 5,750,000
shares of Class A common stuck, the impact of the additional shares, which was
partially offset by approximately $1.0 million of additional interest income
from investing the net offering proceeds, was to reduce net income and income
from continuing operations by $0.02 per share in the fourth quarter of 2006.

      Sales for the year ended December 31, 2006 were $1,230,777,000, an
increase of $306,431,000, or 33%, compared to the year ended December 31, 2005.
Net income for the year ended December 31, 2006 was $73,736,000, or $2.19 per
share, which includes a loss from discontinued operations of $3,357,000, or
$0.10 per share, versus net income of $54,599,000, or $1.66 per share, which
included a loss from discontinued operations of $421,000, or $0.01 per share,
for the year ended December 31, 2005. Income from continuing operations for the
year ended December 31, 2006 increased by $22,073,000, or 40% to $77,093,000, or
$2.29 per share, compared to income from continuing operations of $55,020,000,
or $1.67 per share, for the previous year.

      For the year ended December 31, 2006 the Company recorded income, net of
tax, of $1,465,000, or $0.04 per share, for its manufacturing and restructuring
plan, compared to a charge of $1,633,000, or $0.05 per share, for the previous
year. Gains from the sales of two facilities in Italy were offset by costs
incurred for severance programs in Europe and China and accelerated depreciation
in China in 2006. In 2005, costs related primarily to European severance costs
and accelerated depreciation for the closure of a U.S. manufacturing plant.


      Patrick S. O'Keefe, Chief Executive Officer, commented, "All segments
again contributed to record fourth quarter results, which were primarily due to
acquisitions and internal growth. The sales increase was achieved through
contributions from acquired companies of $49,160,000, or 20%, internal growth of
$28,711,000, or 12%, and, to a lesser extent, from favorable changes in foreign
exchange rates of $8,237,000, or 3%. Acquired growth was primarily attributable
to the December 2005 acquisitions of Core Industries Inc. (which included the
FEBCO, Mueller Steam Specialty and Polyjet Valves product lines) and Dormont
Manufacturing Company and the May 2006 acquisition of ATS Expansion Group."

      "Sales in our North American segment increased for the fourth quarter of
2006 by $39,377,000, or 24%, to $204,692,000 compared to $165,315,000 for the
fourth quarter of 2005. This increase was achieved through the inclusion of
acquired company sales of $26,028,000, or 16%, internal sales growth of
$13,037,000, or 8%, and, to a lesser extent, from favorable foreign exchange
rates of $312,000 associated with the strengthening of the Canadian dollar
versus the U.S. dollar."

      "Internal sales growth in our North American wholesale market increased 9%
over the fourth quarter of 2005. This increase was primarily due to price
increases implemented to cover increases in the costs of copper and other raw
materials. Internal growth in our North American home improvement retail market
was 6% for the fourth quarter of 2006 over the fourth quarter of 2005. This
increase is primarily due to price increases in certain product lines."

      "We derived 33% of our total sales for the fourth quarter of 2006 from our
European segment. European sales increased $39,247,000, or 55%, to $109,969,000
compared to $70,722,000 for the fourth quarter of 2005. This increase was
achieved through the inclusion of acquired company sales totaling $18,049,000,
or 26%, internal growth of $13,571,000, or 19%, and a favorable foreign exchange
movement associated with the strengthening of the euro versus the US dollar of
$7,627,000, or 10%. Our internal growth in Europe was fairly broad-based with
most markets and channels showing improvement. Sales growth in our German OEM
and wholesale markets was particularly strong in the fourth quarter, as were
Italian OEM sales."

      "China's segment sales in the fourth quarter of 2006 increased $7,484,000
or 89%, to $15,854,000 compared to the fourth quarter of 2005. This increase was
achieved through the inclusion of acquired company sales totaling $5,083,000, or
61%, internal growth of $2,103,000, or 25%, and favorable foreign exchange rates
associated with the Chinese yuan strengthening against the U.S. dollar of
$298,000, or 3%. Acquired growth was attributable primarily to the April 2006
acquisition of Changsha Valves Works."


      Mr. O'Keefe commented, "Our operating income for the fourth quarter of
2006 increased by $3,542,000, or 14%, to $29,681,000 as compared to $26,139,000
for the fourth quarter of 2005. Quarter-on-quarter internal growth contributed
$3,210,000, or 12%, acquisitions provided $2,033,000, or 8%, and favorable
foreign exchange movements contributed $1,093,000, or 4%, partially offset by
increased restructuring costs of $2,794,000, or 10%. Operating margins in the
fourth quarter of 2006 decreased by approximately 170 basis points to 9.0% as
compared to 10.7% in the fourth quarter of 2005. Operating margins were affected
by increased copper costs, increased acquisition related charges, increased
manufacturing restructuring costs and increased administrative costs."

      The effective tax rate for the fourth quarter of 2006 was 31% compared
with 36% in the fourth quarter of 2005. Earnings mix between segments
contributed to the decrease and is being driven by higher profits in China being
taxed at lower effective rates.

      The loss from discontinued operations in the fourth quarter of 2005
includes an after-tax charge of $236,000, or $0.01 per share, for costs
associated with the James Jones litigation.

      The Company generated $82,231,000 in net cash provided from continuing
operations for the year ended December 31, 2006 as compared to $51,867,000 for
the year ended December 31, 2005. Free cash flow (a non-GAAP financial measure)
for the year ended December 31, 2006 was $57,005,000 compared with $23,449,000
for the year ended December 31, 2005 (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) decreased to 11% for the year ended December 31, 2006 from
33% in the prior year as the result of the Company's 2006 equity offering and
private placement offering (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).

      Concerning the Company's financial position, Mr. O' Keefe commented, "With
the completion of the April 2006 private placement bond offering and line of
credit refinancing and the November 2006 stock offering, we have successfully
strengthened our capital structure in order to fund near- and medium-term
acquisitions. We also doubled free cash flow from the previous year. In addition
to cash on hand of $342,979,000 at December 31, 2006, we maintained
approximately $226,000,000 in unused and potentially available funding from our
revolving line of credit."

      To supplement our consolidated financial statements presented on 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.
