          WATTS WATER TECHNOLOGIES REPORTS SECOND QUARTER 2007 RESULTS

      North Andover, MA...July 31, 2007. Watts Water Technologies, Inc. (NYSE:
WTS) today announced results for the second quarter ended July 1, 2007. Sales
were $350,422,000, an increase of $50,247,000, or 17%, compared to the second
quarter of 2006. Net income for the second quarter of 2007 was $17,774,000, or
$0.46 per share, compared to net income of $22,446,000, or $0.68 per share for
the second quarter of 2006. Income from continuing operations for the second
quarter of 2007 decreased by $4,850,000, or 22%, to $17,693,000, or $0.45 per
share, compared to income from continuing operations for the second quarter of
2006 of $22,543,000, or $0.68 per share.

      Sales for the first six months of 2007 were $696,514,000, an increase of
$121,389,000, or 21%, compared to the comparable period of 2006. Net income for
the first six months of 2007 was $37,766,000, or $0.97 per share, compared to
net income of $37,409,000, or $1.13 per share for the comparable period of 2006.
Income from continuing operations for the first six months of 2007 increased by
$110,000 to $37,740,000, or $0.97 per share, compared to income from continuing
operations for the comparable period of 2006 of $37,630,000, or $1.14 per share.

      Income from continuing operations and net income for the second quarter
and first six months of 2006 included approximately $4,100,000, or $0.12 per
share, related to a gain on the sale of a building in 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 $1,900,000 and $3,700,000 in after-tax
income in the second quarter and first six months of 2007, respectively. The
issuance of an additional 5,750,000 shares had a dilutive impact on earnings per
share of $0.02 per share and $0.06 per share in the second quarter and first six
months of 2007, respectively, after considering the interest income from the net
proceeds.

      Operating income for the second quarter of 2007 decreased by $8,244,000 to
$30,316,000, as compared to $38,560,000 for the second quarter of 2006.
Operating income in the second quarter of 2006 included a gain on the sale of a
building in Italy of $6,500,000 while operating income in the second quarter of
2007 included a net charge of approximately $2,945,000 related to an increase in
the Company's workers compensation reserve primarily due to a change in
estimate. The Company continues to experience profit pressures due to increased
raw material costs, which were partially offset by a favorable sales mix derived
from the North American wholesale market.


      Patrick S. O'Keefe, Chief Executive Officer, commented, "Our sales
increase for the second quarter of 2007 was achieved through internal growth of
$26,583,000, or 9%, contributions from acquired companies of $16,590,000, or 6%,
and favorable changes in foreign exchange rates of $7,074,000, or 2%. Acquired
growth was primarily attributable to the 2006 acquisitions of ATS Expansion
Group, Black Teknigas, Limited, Changsha Valve Works, Kim Olofsson Safe
Corporation AB and Calflex Manufacturing, Inc."

      "Sales in our North American segment increased for the second quarter of
2007 by $16,203,000, or 8%, to $224,452,000 compared to $208,249,000 for the
second quarter of 2006. This increase was achieved primarily through internal
sales growth of $14,851,000, or 7%, and the inclusion of acquired company sales
of $1,091,000, or 1%."

      "Internal sales growth in the North American wholesale market increased
11% over the second quarter of 2006. This increase was primarily due to price
increases and unit growth in our commercial markets. Sales into the North
American home improvement retail market were down 7% for the second quarter of
2007 compared to the second quarter of 2006. This decrease was primarily due to
decreased unit sales of our residential brass and tubular products partially
offset by price increases."

      "We derived 31% of our total sales for the second quarter of 2007 from our
European segment. European sales increased $24,365,000, or 29%, to $108,222,000
compared to $83,857,000 for the second quarter of 2006. This increase was
achieved through the inclusion of acquired company sales totaling $13,173,000,
or 16%, favorable foreign exchange movement associated with the strengthening of
the euro versus the US dollar of $6,195,000, or 7%, and internal growth of
$4,997,000, or 6%. Internal sales growth in the OEM market, especially in our
under-floor radiant heating and solar product lines, continued to be
particularly strong in the second quarter."

      "China segment sales in the second quarter of 2007 increased $9,679,000 or
120%, to $17,748,000 compared to the second quarter of 2006. This increase was
achieved through internal growth of $6,735,000, or 83%, acquired company sales
totaling $2,326,000, or 29%, and favorable foreign exchange rates associated
with the Chinese yuan strengthening against the U.S. dollar of $618,000, or 8%.
The increase in internal growth is due to increased domestic shipments of
approximately $3,484,000 and the elimination of the one month reporting lag in
two of our Chinese entities, which amounted to approximately $3,251,000."
