          WATTS WATER TECHNOLOGIES REPORTS SECOND QUARTER 2005 RESULTS


      North Andover, MA...August 2, 2005. Watts Water Technologies, Inc. (NYSE
Symbol "WTS") today announced results for the second quarter ended July 3, 2005.
Sales for the second quarter ended July 3, 2005 were $228,183,000, an increase
of $21,229,000, or 10%, from the second quarter last year. Net income for the
second quarter ended July 3, 2005, was $13,913,000, or $0.42 per share, which
includes a net loss from discontinued operations of $75,000, versus net income
of $13,953,000, or $0.43 per share, which included a net loss from discontinued
operations of $106,000 for the second quarter last year. Income from continuing
operations for the second quarter ended July 3, 2005 decreased $71,000, or 1%,,
to $13,988,000, or $0.42 per share, compared to income from continuing
operations for the second quarter last year of $14,059,000, or $0.43 per share.

      Costs incurred for our manufacturing restructuring plan, net of tax, in
the second quarters of 2005 and 2004 were $241,000, or $0.01 per share, and
$344,000, or $0.01 per share, respectively.

      Sales for the six months ended July 3, 2005 were $447,210,000, an increase
of $54,248,000, or 14%, from the same period last year. Net income for the six
months ended July 3, 2005, was $26,271,000, or $0.80 per share, which includes a
net loss from discontinued operations of $114,000, versus net income of
$24,954,000, or $0.77 per share, which included a net loss of $100,000 from
discontinued operations for the same period last year. Income from continuing
operations increased $1,331,000, or 5%, for the six months ended July 3, 2005,
to $26,385,000, or $0.80 per share, compared to income from continuing
operations for the same period last year of $25,054,000, or $0.77 per share.

      Costs incurred for our manufacturing restructuring plans, net of tax, in
the six months of 2005 and 2004 were $737,000, or $0.02 per share, and
$1,068,000, or $0.03 per share, respectively.

      Patrick S. O'Keefe, Chief Executive Officer, commented, "Our overall
increase in sales for the second quarter as compared to last year was achieved
by internal growth, contributions from acquired companies and the change in
foreign exchange rates. Our internal growth contributed $11,985,000 of the
increase in sales in the second quarter ended July 3, 2005. Acquisitions



contributed sales of $6,387,000 for the second quarter. This acquired growth was
attributable to the June 2005 acquisition of Alamo Water Refiners, Inc., the May
2005 acquisition of Electro Controls Ltd., the January 2005 acquisitions of HF
Scientific, Inc. and Sea Tech, Inc., and the May 2004 acquisition of Orion
Enterprises, Inc. The change in foreign exchange rates for the second quarter
ended July 3, 2005 increased our sales by $2,857,000, due primarily to the
strengthening of the euro versus the U.S. dollar."

      "Our North American segment increased sales for the second quarter ended
July 3, 2005 by 13% to $157,116,000 compared to $138,782,000 last year. This
increase in North American sales was achieved through internal sales growth of
$11,674,000, the inclusion of sales from the acquisitions of Alamo Water
Refiners, Inc., HF Scientific, Inc., Sea Tech, Inc. and Orion Enterprises, Inc.
totaling $5,752,000, and $908,000 due to favorable foreign exchange rates
associated with the strengthening of the Canadian dollar versus the U.S.
dollar."

      "Internal sales growth in the North American wholesale market for the
second quarter ended July 3, 2005 increased 8% as compared to the second quarter
last year. This increase was led by increased sales of backflow prevention
units, as well as strength in our plumbing and under-floor radiant heating
product lines. Our internal sales growth in the North American home improvement
retail market increased 12% for the second quarter ended July 3, 2005 over last
year. This increase was led by new product introductions including flood-safe
connectors, pre-soldered copper fittings, hot water heater connector kits and
hot water re-circulation pumps."

      "We derived 28% of our total sales for the second quarter ended July 3,
2005 from Europe compared to 29% last year. Sales in Europe for the second
quarter ended July 3, 2005 increased $2,655,000, or 4% to $63,636,000, compared
to last year. This increase is due to the favorable foreign exchange rates
associated with the strengthening of the euro versus the U.S. dollar, which
accounted for $1,949,000, the inclusion of the sales from the Electro Controls
Ltd acquisition of $635,000 and internal sales growth of $71,000. The
appreciation of the euro had a minimal impact on European income in the second
quarter ended July 3, 2005, compared with a $0.01 per share effect for the
second quarter last year."

      "Sales in China increased 3% to $7,431,000 for the quarter ended July 3,
2005 from $7,191,000 last year. Earnings in China also improved as compared to
last year primarily due to the increased production levels."

      "Operating income for the quarter ended July 3, 2005 declined 2% to
$24,201,000 as compared to $24,707,000 last year. This decrease is primarily
attributable to the increased costs of our raw materials. We have experienced
significant increases in costs of raw materials since June 2004, and copper and
oil prices remain at historic levels. During the quarter ended July 3, 2005, we
were not able to completely recover these increased costs through reduced
manufacturing costs or increased selling prices in the North American market. We
also incurred incremental pre-tax charges in the second quarter of 2005 of
$541,000 for an acquisition earn out being treated as compensation expense.



These increased costs were partially offset by decreased costs of $697,000 to
comply with the requirements of Section 404 under the Sarbanes-Oxley Act of
2002."

      "We continue with the consolidation of our manufacturing plants in North
America and Europe while continuing to expand our manufacturing capacity in
China and other areas of the world in an effort to lower our cost of
manufacturing. For the second quarter ended July 3, 2005 we recorded a pre-tax
charge of approximately $398,000, which was comprised of $302,000 recorded in
cost of sales primarily for accelerated depreciation for both the expected
closure of a U.S. manufacturing plant and a reduction in the estimated useful
lives of certain manufacturing equipment and $96,000 recorded in selling,
general and administrative expenses for severance costs related to European
restructuring. This compares to $560,000 recorded in cost of goods sold last
year for accelerated depreciation for both the expected closure of a U.S.
manufacturing plant and a reduction in the estimated useful lives of certain
manufacturing equipment."

      On July 8, 2005, the Company acquired the water connector business of the
Donald E. Savard Company located in San Gabriel, California. The acquisition of
the water connector business of Savard is consistent with the Company's theme of
water conservation, safety and control. This acquisition allows the Company to
expand its presence in one of its leading product lines with a brand name that
is well known to the plumbing wholesale market. Savard has annual revenues of
approximately $6 million.

      On July 5, 2005, the Company acquired 100% of the outstanding stock of
Microflex N.V., located in Rotselaar, Belgium. Microflex produces and
distributes flexible, pre-insulated, waterproof PEX pipes for hot and cold water
transport, as well as a range of accessory products including couplings, caps,
and insulation kits in the HVAC and water protection markets. Microflex has
annual revenues of $8.5 million.

      On June 20, 2005, the Company acquired the water softener business of
Alamo Water Refiners, Inc. located in San Antonio, Texas. The products of Alamo
are consistent with the Company's theme of water quality and provide many
synergistic opportunities when utilized in conjunction with its existing water
filtration and water quality businesses. The acquisition of Alamo also expands
its distribution presence into the southwestern U.S. markets. Alamo has annual
revenue of approximately $13 million.

      On May 11, 2005, the Company acquired 100% of the outstanding stock of
Electro Controls Ltd. located in Hounslow, United Kingdom. Electro Controls
designs and assembles a range of electrical controls for the HVAC market, with
sales primarily in the United Kingdom with some export sales to the Middle East.
Electro Controls has annual revenue of approximate $4 million.
