          WATTS WATER TECHNOLOGIES REPORTS FOURTH QUARTER 2005 RESULTS

      North Andover, MA...February 7, 2006. Watts Water Technologies, Inc.
(NYSE: WTS) today announced results for the fourth quarter ended December 31,
2005. Sales were $244,407,000, an increase of $23,001,000, or 10%, compared to
the fourth quarter of 2004. Net income for the fourth quarter ended December 31,
2005 was $14,960,000, or $0.45 per share, which includes a loss from
discontinued operations of $236,000, or $0.01 per share, versus net income of
$8,161,000, or $0.25 per share, which included a loss from discontinued
operations of $1,688,000, or $0.05 per share, for the fourth quarter of 2004.
Income from continuing operations for the fourth quarter ended December 31, 2005
increased by $5,347,000, or 54%, to $15,196,000, or $0.46 per share, compared to
income from continuing operations for the fourth quarter of 2004 of $9,849,000,
or $0.30 per share. Net income and income from continuing operations in 2004
included a charge of $2,289,000 or $0.07 per share that corrected certain
accrued expenses.

      Costs incurred for our manufacturing restructuring plan, net of tax, in
the fourth quarters of 2005 and 2004 were $241,000, or $0.01 per share, and
$408,000, or $0.01 per share, respectively.

      Sales for the year ended December 31, 2005 were $924,346,000, an increase
of $99,788,000, or 12%, compared to the year ended December 31, 2004. Net income
for the year ended December 31, 2005, was $54,599,000, or $1.66 per share, which
includes a loss from discontinued operations of $421,000, or $0.01 per share,
versus net income of $46,820,000, or $1.43 per share, which included a loss from
discontinued operations of $1,918,000, or $0.06 per share, for the year ended
December 31, 2004. Income from continuing operations increased $6,282,000, or
13%, to $55,020,000, or $1.67 per share, for the year ended December 31, 2005
compared to income from continuing operations of $48,738,000, or $1.49 per
share, for the previous year.

      Costs incurred for our manufacturing restructuring plan, net of tax, for
the years ended 2005 and 2004 were $1,633,000, or $0.05 per share, and
$1,825,000, or $0.06 per share, respectively.

      The overall increase in fourth quarter sales was achieved by internal
growth and contributions from acquired companies, offset by an adverse change in
foreign exchange rates. Organic growth was 7% and contributed $14,924,000;
acquisitions contributed 6% or $14,163,000 and a net unfavorable foreign
exchange movement primarily due to the euro devaluation against the dollar,



negatively impacted sales by 3% or $6,086,000. Acquired growth was attributable
to the December 2005 acquisitions of Core Industries Inc. (Febco, Mueller
Specialty Steam and Polyjet Valves product lines) and Dormont Manufacturing
Company, the November 2005 acquisition of Flexflow Tubing LLP, the July 2005
acquisitions of the water connecter business of the Donald E. Savard Company and
Microflex N.V., the June 2005 acquisition of the water softener business of
Alamo Water Refiners, Inc., the May 2005 acquisition of Electro Controls Ltd.,
and the January 2005 acquisitions of HF Scientific, Inc. and Sea Tech, Inc.

      North American segment sales increased for the fourth quarter ended
December 31, 2005 by 14% to $165,315,000 compared to $144,972,000 for the prior
year. This increase in North American sales was achieved through internal sales
growth of $9,120,000, the inclusion of sales from the acquisitions of Core
Industries Inc., Dormont Manufacturing Company, Flexflow Tubing LLP, the water
connecter business of the Donald E. Savard Company, the water softener business
of Alamo Water Refiners, Inc., HF Scientific, Inc. and Sea Tech, Inc. totaling
$10,714,000, and $509,000 due to favorable foreign exchange rates associated
with the strengthening of the Canadian dollar versus the U.S. dollar.

      Organic sales in the North American wholesale market increased 7% over the
fourth quarter of 2004. This increase was led by increased sales of backflow
prevention units, as well as strength in the plumbing and under-floor radiant
heating product lines. Internal sales growth in the North American home
improvement retail market was 5% for the fourth quarter of 2005 over the fourth
quarter of 2004.

      Foreign sales accounted for 38% of total sales for the fourth quarter of
2005, with 29% generated by Europe, 6% from Canada and 3% from China.

      European sales increased $888,000, or 1%, to $70,722,000 compared to the
fourth quarter of 2004. Internal growth of 6%, or $4,231,000, and acquired
growth of 5%, or $3,449,000, were almost completely offset by an unfavorable
foreign exchange movement associated with the weakening of the euro versus the
US dollar of $6,792,000. The acquired growth is due to the inclusion of the
acquired sales of Microflex N.V. and Electro Controls Ltd. Europe experienced
increased market share gains in Germany due to increased marketing and sales
efforts and increased sales into the Eastern European wholesale market, offset
by decreased sales in the OEM market primarily due to the weak economic
environments.

      China's sales increased $1,770,000, or 27%, to $8,370,000 compared to the
fourth quarter of 2004. Internal growth was $1,573,000, or 24%, and was
augmented by a favorable foreign currency movement of approximately 3% as the
yuan strengthened against the U.S. dollar. Sales increased into the domestic
Chinese marketplace with some softening of third-party export sales.



      Operating income in the quarter ended December 31, 2005 increased by
$9,914,000, or 61%, to $26,139,000 as compared to $16,225,000 in 2004. Operating
income in the fourth quarter of 2004 included a pre-tax charge of $4,258,000
that corrected certain accrued expenses. Internal growth provided 50%, or
$5,008,000, of the quarter-on-quarter operating income growth with positive
performances from each region. Acquisitions provided $1,057,000, or 11%, of the
increase with negative foreign exchange movements and reduced quarter-on-quarter
restructuring costs making up the remainder. Operating margin was 10.7% for the
quarter ended December 31, 2005 versus 9.3%, adjusted for the pre-tax charge
above, for the quarter ended December 31, 2004. Sequential operating margin
increased from 9.8% for the third quarter ended October 2, 2005 as the Company
experienced slightly higher margins and also benefited from reduced insurance
and Sarbanes Oxley costs.

      In the quarter ended December 31, 2005, the Company recorded in cost of
sales a net pre-tax charge of approximately $111,000 primarily for costs related
to European restructuring efforts. Additionally, approximately $267,000 for
European severance related charges were charged to selling, general and
administrative expenses. Costs related with the Sarbanes-Oxley Act were reduced
approximately $1,400,000 from the fourth quarter of 2004.

      The effective tax rate for the fourth quarter of 2005 was 36% compared
with 23% in the fourth quarter of 2004. In the fourth quarter of 2004, the
Company benefited from previously unrecognized deferred tax assets of
approximately $800,000 in China, of which $322,000 related to net operating loss
carry forwards. Further, in the fourth quarter of 2004, the Company recorded a
benefit for certain state tax credits of $164,000 and recorded a credit of
$462,000 as part of accounting corrections made. Earnings mix between periods
also contributed to the increase in the effective tax rate in the fourth quarter
of 2005.

      The loss from discontinued operations in the fourth quarter of 2005 is
comprised of an after-tax charge of $236,000, or $0.01 per share, for costs
associated with the James Jones litigation as compared with a loss of
$1,688,000, or $0.05 per share, in 2004 which included an after-tax charge of
$783,000 for the divestiture of Jameco International, LLC and $905,000 in James
Jones-related legal costs.

      The Company generated $51,867,000 in net cash provided from continuing
operations for the year ended December 31, 2005 as compared to $40,210,000 for
the year ended December 31, 2004. Free cash flow for the year ended December 31,
2005 was $23,449,000 compared with $12,283,000 for the year ended December 31,
2004 (Please refer to Table 1 at the end of this press release for a
reconciliation of free cash flow to net cash provided by continuing operations).
The Company's net debt to capitalization ratio increased to 33% for the year
ended December 31, 2005 from 19% in the prior year as the result of the
Company's acquisition program in 2005 which was funded with approximately
$153,500,000 in debt financing during the 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).



      Addressing the results for the fourth quarter, Patrick S. O'Keefe, Chief
Executive Officer, commented, "We are pleased with our overall performance in
the fourth quarter of 2005. Despite near-record high commodity prices,
especially in oil and copper-based raw materials, unfavorable movement in the
euro against the dollar and a tepid economic environment throughout much of
Europe, we achieved record results for the quarter. All regions delivered solid
operational growth in sales and operating income. Our 2005 acquisitions
contributed as expected and helped to boost margins, especially in Europe. We
continued our program to reduce manufacturing costs by sourcing product from,
and consolidating operations into, low-cost areas in an effort to counteract
commodity pressure on margins. We have leveraged our balance sheet in order to
fund acquisitions, but due to our disciplined approach to growth, we have
maintained a conservative capital structure. At December 31, 2005, we maintained
approximately $100,000,000 in unused and available funding from our revolving
credit facility."

      To supplement our unaudited consolidated financial statements presented on
a generally accepted accounting principles (GAAP) basis, we sometimes use
non-GAAP 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 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 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.
