           WATTS WATER TECHNOLOGIES REPORTS FIRST QUARTER 2006 RESULTS

      North Andover, MA...May 2, 2006. Watts Water Technologies, Inc. (NYSE:
WTS) today announced results for the first quarter ended April 2, 2006. Sales
were $274,950,000, an increase of $55,923,000, or 26%, compared to the first
quarter of 2005. Net income for the first quarter of 2006 was $14,963,000, or
$0.46 per share, which included a loss from discontinued operations of $124,000,
versus net income of $12,358,000, or $0.37 per share, which included a loss from
discontinued operations of $39,000, for the first quarter of 2005. Income from
continuing operations for the first quarter of 2006 increased by $2,690,000, or
22%, to $15,087,000, or $0.46 per share, compared to income from continuing
operations for the first quarter of 2005 of $12,397,000, or $0.37 per share.

      The Company adopted Financial Accounting Standards Board Statement No.
123R (FAS 123R) that requires the Company to expense the value of employee stock
options and similar awards effective January 1, 2006. This resulted in
incremental pre-tax costs in selling, general and administrative expense of
approximately $450,000 for the first quarter of 2006 compared to the comparable
period last year.

      Patrick S. O'Keefe, Chief Executive Officer, commented, "We are pleased
with our overall performance in the first quarter of 2006. We achieved record
results with all segments contributing to our growth in sales and earnings. The
increase in sales was achieved through contributions from acquired companies and
internal growth, offset by an adverse change in foreign exchange rates.
Acquisitions contributed 17% or $37,126,000; internal growth was 11% and
contributed $23,255,000; and a net unfavorable foreign exchange movement,
primarily due to the euro devaluation against the dollar, offset these increases
by 2%, or $4,458,000. Acquired growth was attributable to the December 2005
acquisitions of Core Industries Inc. (FEBCO, Mueller Steam Specialty and Polyjet
Valves product lines) and Dormont Manufacturing Company, the November 2005
acquisition of Flexflow Tubing LLP, the July 2005 acquisitions of the water
connecter business of the Donald E. Savard Company and Microflex N.V., the June
2005 acquisition of the water softener business of Alamo Water Refiners, Inc.,
and the May 2005 acquisition of Electro Controls Ltd."

      "Our North American segment sales increased for the first quarter of 2006
by 33% to $196,566,000 compared to $147,477,000 for first quarter of 2005. This
increase was achieved through the inclusion of acquired sales totaling


$34,316,000, or 23%, internal sales growth of $13,967,000, or 9%, and favorable
foreign exchange rates of $806,000 associated with the strengthening of the
Canadian dollar versus the U.S. dollar."

      "Internal sales in our North American wholesale market increased 9% over
the first quarter of 2005. This increase was led by increased sales of water
pressure regulators, relief valves and backflow prevention units, as well as
strength in the plumbing and under-floor radiant heating product lines. Internal
growth in our North American home improvement retail market was 10% for the
first quarter of 2006 over the first quarter of 2005. This increase was led by
increased sales of fittings and supply lines and under-floor radiant heating
product lines."

      "We derived 26% of our total sales for the first quarter of 2006 from our
European segment. European sales increased $5,825,000, or 9%, to $72,259,000
compared to the first quarter of 2005. Internal growth of 13%, or $8,450,000,
and acquired growth of 4%, or $2,810,000, was offset by an unfavorable foreign
exchange movement associated with the weakening of the euro versus the US dollar
of $5,435,000. Our internal growth in Europe was broad-based with most markets
and channels exhibiting improvement."

      "China's segment sales in the first quarter of 2006 increased $1,009,000,
or 20%, to $6,125,000 compared to the first quarter of 2005. Internal growth was
$838,000, or 17%, and $171,000, or 3%, was due to favorable foreign exchange
rates associated with the yuan strengthening against the U.S. dollar. The
internal growth in China was due to a 22% increase in the domestic market, as
well as, an increase into the export market over the comparable period last
year."

      "Our operating income for the first quarter of 2006 increased by
$5,222,000, or 25%, to $26,532,000 as compared to $21,310,000 in 2005. Internal
growth was 12%, or $2,568,000, with positive performances from each segment.
Acquisitions provided $2,590,000, or 12%, and reduced quarter-on-quarter
restructuring costs contributed to the increase with unfavorable foreign
exchange movements offsetting these increases."

      O'Keefe concluded, "On April 27, 2006, we restructured our long-term debt.
We completed a private placement offering of $225,000,000 of 5.85% senior
unsecured notes payable in April 2016. We used the net proceeds from the notes
to repay $147,000,000 outstanding under our revolving credit facility. The
balance of the net proceeds will be used to finance future acquisitions and for
general corporate purposes. Additionally, we amended our revolving credit
facility, increasing our borrowing capacity from $300,000,000 to $350,000,000,
reducing the interest spread and extending the term to April 2011."

      The Company incurred costs, net of tax, of $149,000 and $496,000,
respectively, in the first quarters of 2006 and 2005 for its manufacturing
restructuring plan. In the first quarter of 2006, the Company recorded a net
pre-tax charge of approximately $235,000 primarily for severance costs related
to European restructuring efforts. For the first quarter of 2005, the Company


recorded a pre-tax charge of approximately $774,000, which consisted 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.

      The loss from discontinued operations in the first quarters of 2006 and
2005 were for costs associated with the James Jones litigation.
