           WATTS WATER TECHNOLOGIES REPORTS FIRST QUARTER 2005 RESULTS

        North Andover, MA...May 3, 2005. Watts Water Technologies, Inc. (NYSE
Symbol "WTS") today announced results for the first quarter ended April 3, 2005.
Sales for the first quarter ended April 3, 2005 were $219,027,000, an increase
of $33,019,000, or 18%, from the first quarter ended March 28, 2004. Net income
for the first quarter ended April 3, 2005, was $12,358,000, or $0.37 per share,
which includes a net loss from discontinued operations of $39,000. Income from
continuing operations increased $1,402,000, or 13%, for the first quarter ended
April 3, 2005, to $12,397,000, or $0.37 per share, compared to income from
continuing operations for the first quarter ended March 28, 2004 of $10,995,000,
or $0.34 per share.

        Restructuring costs, net of tax, incurred in the first quarters of 2005
and 2004 were $496,000, or $0.02 per share, and $724,000, or $0.02 per share,
respectively.

        Patrick S. O'Keefe, Chief Executive Officer, commented, "Our overall
increase in sales was achieved by internal growth, contributions from acquired
companies and the change in foreign exchange rates. Our internal growth
contributed $20,104,000 of the increase in sales in the first quarter ended
April 3, 2005 over the first quarter ended March 28, 2004. Our acquisitions
contributed $9,303,000 of sales for the first quarter ended April 3, 2005 over
the first quarter ended March 28, 2004. This acquired growth was attributable to
the January 2005 acquisitions of HF Scientific, Inc. and Sea Tech, Inc., the May
2004 acquisition of Orion Enterprises, Inc. and the April 2004 acquisition of
TEAM Precision Pipework, Ltd. The change in foreign exchange rates for the first
quarter ended April 3, 2005 increased our sales by $3,612,000 over the first
quarter ended March 28, 2004 due primarily to the strengthening of the euro
versus the U.S. dollar.

        "Our North American segment increased sales for the first quarter ended
April 3, 2005 by 22% to $147,477,000 compared to $120,982,000 for the first
quarter ended March 28, 2004. This increase in North American sales was achieved
through internal sales growth of $19,245,000, the inclusion of sales from the
acquisitions of HF Scientific, Inc., Sea Tech, Inc. and Orion Enterprises, Inc.
totaling $6,500,000, and $750,000 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
first quarter ended April 3, 2005 increased 14% over the first quarter ended
March 28, 2004. 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 22% for the first quarter ended April 3, 2005 over the
first quarter ended March 28, 2004. This increase was led by new product
introductions including pre-soldered copper fittings, hot water re-circulation
pumps and hot water heater connector kits."

        "We derived 30% of our total sales for the first quarter ended April 3,
2005 from Europe compared to 32% in the first quarter ended March 28, 2004.
Sales in Europe for the first quarter ended April 3, 2005 increased $6,401,000,
or 11% to $66,434,000, compared to the first quarter ended March 28, 2004. 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
$2,862,000, the inclusion of the sales from the TEAM Precision Pipework, Ltd.
acquisition of $2,803,000 and internal sales growth of $736,000. The
appreciation of the euro also had a positive impact on European income of $0.01
per share in the first quarter ended April 3, 2005, compared with a $0.02 per
share effect for the first quarter ended March 28, 2004."

        "Sales in China increased 2% to $5,116,000 for the quarter ended April
3, 2005 from $4,993,000 for the quarter ended March 28, 2004. The improvement in
earnings from Chinese operations over last year was primarily due to the
increased production levels and lower scrap expenses."

        "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 first quarter ended April 3, 2005 we recorded a pre-tax
charge of approximately $774,000, which was comprised of $412,000 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 $362,000 recorded in selling,
general and administrative expenses for severance costs related to European
restructuring. This compares to $1,177,000 recorded in cost of goods sold in the
first quarter ended March 28, 2004 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.

        "We also incurred incremental pretax charges in the first quarter of
2005 including $709,000 for an acquisition earn-out being treated as
compensation expense and costs related to compliance with Sarbanes-Oxley
requirements of approximately $1,200,000."

        On January 5, 2005, the Company acquired 100% of the outstanding stock

        On March 29, 2004, a wholly-owned subsidiary of the Company acquired the

that had been held by the Company's former joint venture partner for

with a know-how transfer and non-compete agreement. As of April 3, 2005 the
Company had paid $5,750,000 in cash. The Company now owns 100% of Shida. The
Company had made prior investments in 2003 and 2002 totaling $8,000,000 in cash
for its initial 60% interest. Shida is a manufacturer of a variety of plumbing
products sold both into the Chinese domestic market and export markets.
