WATTS WATER TECHNOLOGIES REPORTS FIRST QUARTER 2007 RESULTS

      North Andover, MA...May 1, 2007. Watts Water Technologies, Inc. (NYSE:
WTS) today announced results for the first quarter ended April 1, 2007. Sales
were $346,092,000, an increase of $71,142,000, or 26%, compared to the first
quarter of 2006. Net income for the first quarter of 2007 was $19,992,000, or
$0.51 per share, compared to net income of $14,963,000, or $0.46 per share for
the first quarter of 2006. Income from continuing operations for the first
quarter of 2007 increased by $4,960,000, or 33%, to $20,047,000, or $0.51 per
share, compared to income from continuing operations for the first quarter of
2006 of $15,087,000, or $0.46 per share. Income from continuing operations for
the first quarter of 2007 includes a tax refund of $1,910,000, or $0.05 per
share, due to recent changes in the tax laws of Italy.

      In November 2006, the Company completed a public offering of 5,750,000
shares of Class A common stock and received net proceeds of approximately
$219,000,000. The net proceeds are currently being invested in short-term
securities, which provided approximately $1,800,000 in after-tax income in the
first quarter of 2007. The additional 5,750,000 shares had a dilutive impact of
$0.04 per share in the first quarter of 2007, after considering the interest
income from the net proceeds.

      Patrick S. O'Keefe, Chief Executive Officer, commented, "Our sales
increase was achieved through internal growth of $35,389,000, or 13%,
contributions from acquired companies of $27,878,000, or 10%, and favorable
changes in foreign exchange rates of $7,875,000, or 3%. Acquired growth was
primarily attributable to the 2006 acquisitions of ATS Expansion Group, Changsha
Valve Works, Black Teknigas, Limited, Kim Olofsson Safe Corporation AB and
Calflex Manufacturing, Inc."

      "Sales in our North American segment increased for the first quarter of
2007 by $21,759,000, or 11%, to $218,325,000 compared to $196,566,000 for the
first quarter of 2006. This increase was achieved through internal sales growth
of $20,210,000, or 10% and the inclusion of acquired company sales of
$1,661,000, or 1%."

      "Internal sales growth in the North American wholesale market increased
13% over the first quarter of 2006. This increase was primarily due to price
increases and unit growth in our commercial markets. Internal growth in the
North American home improvement retail market was 2% for the first quarter of
2007 over the first quarter of 2006. This increase was primarily due to price
increases partially offset by decreased sales of residential products."


      "We derived 33% of our total sales for the first quarter of 2007 from our
European segment. European sales increased $43,286,000, or 60%, to $115,545,000
compared to $72,259,000 for the first quarter of 2006. This increase was
achieved through the inclusion of acquired company sales totaling $22,745,000,
or 31%, internal growth of $12,878,000, or 18%, and favorable foreign exchange
movement associated with the strengthening of the euro versus the US dollar of
$7,663,000, or 11%. Our internal growth in Europe was fairly broad-based with
most channels performing well. Sales growth in the German OEM market, especially
in our under-floor radiant heating and solar product lines, was particularly
strong in the first quarter."

      "China segment sales in the first quarter of 2007 increased $6,097,000 or
100%, to $12,222,000 compared to the first quarter of 2006. This increase was
achieved through the inclusion of acquired company sales totaling $3,472,000, or
57%, internal growth of $2,301,000, or 38%, and favorable foreign exchange rates
associated with the Chinese yuan strengthening against the U.S. dollar of
$324,000, or 5%."

      Mr. O'Keefe commented, "Our operating income for the first quarter of 2007
increased by $3,835,000, or 14%, to $30,367,000 as compared to $26,532,000 for
the first quarter of 2006. Operating margins in the first quarter of 2007
decreased by approximately 80 basis points to 8.8% as compared to 9.6% in the
first quarter of 2006. The decrease in operating margin is primarily due to a
decline in gross margin percentage caused by increased raw material costs
partially offset by a decrease in selling and general administrative expenses as
a percent of sales."

      The effective tax rate for the first quarter of 2007 was 26% compared with
35% in the first quarter of 2006. The decrease was primarily due to a tax refund
recorded in Italy of approximately $1,910,000 and by higher profits in China
being taxed at lower effective rates.
