          WATTS WATER TECHNOLOGIES REPORTS SECOND QUARTER 2006 RESULTS

      North Andover, MA...August 1, 2006. Watts Water Technologies, Inc. (NYSE:
WTS) today announced results for the second quarter ended July 2, 2006. Sales
were $300,175,000, an increase of $71,992,000, or 32%, compared to the second
quarter of 2005. Net income for the second quarter of 2006 was $22,446,000, or
$0.68 per share, compared to net income of $13,913,000, or $0.42 per share, for
the second quarter of 2005. Income from continuing operations for the second
quarter of 2006 increased by $8,555,000, or 61%, to $22,543,000, or $0.68 per
share, compared to income from continuing operations for the second quarter of
2005 of $13,988,000, or $0.42 per share.

      The Company recorded income, net of tax, of $3,554,000, or $0.11 per
share, in the second quarter of 2006 compared to a loss, net of tax, of
$241,000, or $0.01 per share, in the second quarter of 2005 for its
manufacturing restructuring plan. In the second quarter of 2006, the Company
recorded an after tax gain of approximately $4,100,000 related to a building
sale in Italy. This gain was partially offset by after tax costs of
approximately $546,000 primarily for severance costs related to its European and
Chinese restructuring plans. For the second quarter of 2005, the costs were
primarily for accelerated depreciation for both the closure of a U.S.
manufacturing plant and for severance costs related to the Company's European
restructuring plan.

      Sales for the first six months of 2006 were $575,125,000, an increase of
$127,915,000, or 29%, compared to the first six months of 2005. Net income for
the first six months of 2006 was $37,409,000, or $1.13 per share, versus net
income of $26,271,000, or $0.80 per share, for the first six months of 2005.
Income from continuing operations for the first six months of 2006 increased by
$11,245,000, or 43%, to $37,630,000, or $1.14 per share, compared to income from
continuing operations for the first six months of 2005 of $26,385,000, or $0.80
per share.

      The Company recorded income, net of tax, of $3,405,000, or $0.10 per
share, in the first six months of 2006 compared to a loss, net of tax, of
$737,000, or $0.02 per share, in the first six months of 2005 for its
manufacturing restructuring plan. In the first six months of 2006, the Company
benefited from the previously mentioned building sale in Italy. This benefit was
offset by after tax costs of approximately $695,000, or $0.02 per share,
primarily for severance costs related to the Company's European and Chinese
restructuring plans. For the first six months of 2005, the costs were primarily
for accelerated depreciation for both the closure of a U.S. manufacturing plant
and for severance costs related to the Company's European restructuring plan.


      Patrick S. O'Keefe, Chief Executive Officer, commented, "During the second
quarter, the Company was able to maintain the momentum in operating performance
we experienced in the first quarter of this year. Aided by acquisitions and
internal growth, we again achieved record results with all segments contributing
to our growth in sales and earnings. The sales increase was achieved through
contributions from acquired companies of $50,946,000, or 23%, internal growth of
$18,236,000, or 8%, and to a lesser extent from favorable changes in foreign
exchange rates of $2,810,000, or 1%. Acquired growth was primarily attributable
to the December 2005 acquisitions of Core Industries Inc. (which included the
FEBCO, Mueller Steam Specialty and Polyjet Valves product lines) and Dormont
Manufacturing Company and the May 2006 acquisition of ATS Expansion Group.

      "Sales in our North American segment increased for the second quarter of
2006 by $51,133,000, or 33%, to $208,249,000 compared to $157,116,000 for second
quarter of 2005. This increase was achieved through the inclusion of acquired
sales totaling $40,167,000, or 26%, internal sales growth of $9,511,000, or 6%,
and favorable foreign exchange rates of $1,455,000, or 1%, associated with the
strengthening of the Canadian dollar versus the U.S. dollar.

      "Internal sales in our North American wholesale market increased 7% over
the second quarter of 2005. This increase was primarily due to price increases
implemented to cover recent increases in the prices of copper and other raw
materials and increased unit sales of our plumbing and heating and backflow
products. Internal growth in our North American home improvement retail market
was 5% for the second quarter of 2006 over the second quarter of 2005. This
increase was led by increased sales of under-floor radiant heating product
lines.

      "We derived 28% of our total sales for the second quarter of 2006 from our
European segment. European sales increased $20,221,000, or 32%, to $83,857,000
compared to the second quarter of 2005. This increase was achieved through the
inclusion of acquired sales totaling $10,155,000, or 16%, internal growth of
$8,947,000, or 14%, and a favorable foreign exchange movement associated with
the strengthening of the euro versus the US dollar of $1,119,000, or 2%. Our
internal growth in Europe was broad-based with most markets and channels
exhibiting improvement. Sales growth in our OEM market and Italian wholesale
market were particularly strong in the second quarter.

      "China's segment sales in the second quarter of 2006 increased $638,000,
or 9%, to $8,069,000 compared to the second quarter of 2005. This increase was
achieved through the inclusion of acquired sales totaling $624,000, or 8%,
favorable foreign exchange rates associated with the yuan strengthening against
the U.S. dollar of $236,000, partially offset by a decline in internal sales of
$222,000.

      Mr. O'Keefe concluded, "Our operating income for the second quarter of
2006 increased by $14,035,000, or 58%, to $38,236,000 as compared to $24,201,000
in 2005. Our quarter-on-quarter restructuring costs contributed $6,067,000, or
25%, acquisitions provided $5,659,000, or 23%, internal growth contributed
$1,736,000, or 7%, and favorable foreign exchange movements contributed
$573,000, or 3%. Our overall margins were impacted by a favorable mix within the
North American wholesale market partially offset by write-downs of our inventory
carrying values of certain product lines."
