           WATTS WATER TECHNOLOGIES REPORTS THIRD QUARTER 2005 RESULTS

      North Andover, MA. October 31, 2005. Watts Water Technologies, Inc. (NYSE
Symbol "WTS") today announced results for the third quarter ended October 2,
2005. Sales for the third quarter ended October 2, 2005 were $232,729,000, an
increase of $22,539,000, or 11%, from the third quarter last year. Net income
for the third quarter ended October 2, 2005 was $13,368,000, or $0.40 per share,
which includes a loss from discontinued operations of $71,000, versus net income
of $13,705,000, or $0.42 per share, which included a loss from discontinued
operations of $130,000 for the third quarter last year. Income from continuing
operations for the third quarter ended October 2, 2005 decreased $396,000, or
3%, to $13,439,000, or $0.41 per share, compared to income from continuing
operations for the third quarter last year of $13,835,000, or $0.42 per share.

      Costs incurred for our manufacturing restructuring plan, net of tax, in
the third quarters of 2005 and 2004 were $655,000, or $0.02 per share, and
$349,000, or $0.01 per share, respectively.

      Sales for the nine months ended October 2, 2005 were $679,939,000, an
increase of $76,787,000, or 13%, from the same period last year. Net income for
the nine months ended October 2, 2005 was $39,639,000, or $1.20 per share, which
includes a loss from discontinued operations of $185,000, versus net income of
$38,659,000, or $1.18 per share, which included a loss of $230,000 from
discontinued operations for the same period last year. Income from continuing
operations increased $935,000, or 2%, for the nine months ended October 2, 2005,
to $39,824,000, or $1.21 per share, compared to income from continuing
operations for the same period last year of $38,889,000, or $1.19 per share.

      Costs incurred for our manufacturing restructuring plans, net of tax, in
the nine months of 2005 and 2004 were $1,392,000, or $0.04 per share, and
$1,417,000, or $0.04 per share, respectively.

      Patrick S. O'Keefe, Chief Executive Officer, commented, "Our overall
increase in sales for the third quarter as compared to last year was achieved by
internal growth and contributions from acquired companies. Changes in net
foreign exchange had a minimal positive effect on sales. Our internal growth
contributed $11,845,000 of the increase in sales in the third quarter ended


October 2, 2005. Acquisitions contributed sales of $10,473,000 for the third
quarter. This acquired growth was attributable to the July 2005 acquisitions of
the water connecter business of 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."

      "Our North American segment increased sales for the third quarter ended
October 2, 2005 by 14% to $160,029,000 compared to $140,403,000 last year. This
increase in North American sales was achieved through internal sales growth of
$11,757,000, the inclusion of sales from the acquisitions of the water connecter
business of Donald E. Savard Company, the water softener business of Alamo Water
Refiners, Inc., HF Scientific, Inc. and Sea Tech, Inc. totaling $6,924,000, and
$945,000 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
third quarter ended October 2, 2005 increased 8% as compared to the third
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 13% for the third quarter ended October 2,
2005 over last year. This increase was primarily due to the new product
introduction of FloodSafeTM connectors."

      "We derived 28% of our total sales for the third quarter ended October 2,
2005 from Europe compared to 30% last year. Sales in Europe for the third
quarter ended October 2, 2005 increased $3,168,000, or 5%, to $65,554,000,
compared to last year. This increase is due to the inclusion of the acquired
sales of Microflex N.V. and Electro Controls Ltd. totaling $3,549,000, internal
sales growth of $495,000 offset by $876,000 of unfavorable foreign exchange
associated with the weakening of the euro versus the U.S. dollar. We 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."

      "Sales in China decreased $255,000 to $7,146,000 for the quarter ended
October 2, 2005 from $7,401,000 last year. Sales into the Chinese domestic
market increased offset by a decrease in the Chinese export market which is now
handled by our U.S. subsidiaries. Our China segment experienced favorable
foreign exchange rates associated with the strengthening of the yuan versus the
U.S. dollar."

      "Operating income for the quarter ended October 2, 2005 remained
relatively flat at $22,905,000 as compared to $22,890,000 last year. This 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. We were not able to completely


recover these increased costs through reduced manufacturing costs or increased
selling prices in the North American market. Additionally, the economies in our
main European countries of Germany, Italy and France continued to be weak. These
factors are offset by the contribution of operating income from our acquired
companies and increased profits in China due to increased capacity utilization
and low cost sourcing."

      "We are continuing 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 third quarter ended October 2, 2005 we recorded a pre-tax
charge of approximately $995,000, which was comprised of $991,000 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 $4,000 recorded in selling, general
and administrative expenses for severance costs related to European
restructuring. This compares to $567,000 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.
