WATTS WATER TECHNOLOGIES REPORTS THIRD QUARTER 2006 RESULTS

      North Andover, MA...October 31, 2006. Watts Water Technologies, Inc.
(NYSE: WTS) today announced results for the third quarter ended October 1, 2006.
Sales were $325,137,000, an increase of $92,408,000, or 40%, compared to the
third quarter of 2005. Net income for the third quarter of 2006 was $18,187,000,
or $0.55 per share, which includes a loss from discontinued operations of
$3,137,000, or ($0.09) per share, compared to net income of $13,368,000, or
$0.40 per share, which included a loss from discontinued operations of $71,000,
for the third quarter of 2005. Income from continuing operations for the third
quarter of 2006 increased by $7,885,000, or 59%, to $21,324,000, or $0.65 per
share, compared to income from continuing operations for the third quarter of
2005 of $13,439,000, or $0.41 per share.

      Sales for the first nine months of 2006 were $900,262,000, an increase of
$220,323,000, or 32%, compared to the first nine months of 2005. Net income for
the first nine months of 2006 was $55,596,000, or $1.68 per share, which
includes a loss from discontinued operations of $3,358,000, or ($0.10) per
share, versus net income of $39,639,000, or $1.20 per share, which included a
loss from discontinued operations of $185,000, or ($0.01) per share, for the
first nine months of 2005. Income from continuing operations for the first nine
months of 2006 increased by $19,130,000, or 48%, to $58,954,000, or $1.79 per
share, compared to income from continuing operations for the first nine months
of 2005 of $39,824,000, or $1.21 per share.

      Patrick S. O'Keefe, Chief Executive Officer, commented, "The Company
achieved record results in both sales and earnings during the quarter. All
segments contributed to the results, which were primarily due to acquisitions
and internal growth. The sales increase was achieved through contributions from
acquired companies of $55,573,000, or 24%, internal growth of $31,948,000, or
14%, and, to a lesser extent, from favorable changes in foreign exchange rates
of $4,887,000, or 2%. 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 third quarter of
2006 by $51,740,000, or 32%, to $211,769,000 compared to $160,029,000 for the
third quarter of 2005. This increase was achieved through the inclusion of
acquired company sales of $33,348,000, or 21%, internal sales growth of
$17,447,000, or 11%, and, to a lesser extent, from favorable foreign exchange
rates of $945,000 associated with the strengthening of the Canadian dollar
versus the U.S. dollar.


      "Internal sales in our North American wholesale market increased 14% over
the third quarter of 2005. This increase was primarily due to price increases
implemented to cover increases in the costs 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 2% for
the third quarter of 2006 over the third quarter of 2005. This increase is
primarily due to price increases in certain product lines.

      "We derived 31% of our total sales for the third quarter of 2006 from our
European segment. European sales increased $35,883,000, or 55%, to $101,437,000
compared to $65,554,000 for the third quarter of 2005. This increase was
achieved through the inclusion of acquired company sales totaling $17,848,000,
or 27%, internal growth of $14,239,000, or 22%, and a favorable foreign exchange
movement associated with the strengthening of the euro versus the US dollar of
$3,796,000, or 6%. Our internal growth in Europe was broad-based with most
markets and channels showing improvement. Sales growth in our German OEM and
wholesale markets was particularly strong in the third quarter.

      "China's segment sales in the third quarter of 2006 increased $4,785,000,
or 67%, to $11,931,000 compared to the third quarter of 2005. This increase was
achieved through the inclusion of acquired company sales totaling $4,377,000, or
61%, internal growth of $262,000, or 4%, and favorable foreign exchange rates
associated with the yuan strengthening against the U.S. dollar of $146,000, or
2%."

      Mr. O'Keefe concluded, "Our operating income for the third quarter of 2006
increased by $13,133,000, or 57%, to $36,038,000 as compared to $22,905,000 in
the third quarter of 2005. Operating margins in the third quarter of 2006
increased by approximately 120 basis points to 11.1% as compared to 9.8% in the
third quarter of 2005. Our quarter-on-quarter internal growth contributed
$7,459,000, or 32%, acquisitions provided $5,132,000, or 22%, and favorable
foreign exchange movements contributed $828,000, or 4%, partially offset by
increased restructuring costs of $286,000, or 1%. Our `overall margins were
positively affected by a favorable mix within the North American wholesale
market, manufacturing efficiencies in China, acquisitions and leveraged selling,
general and administrative expenses in Europe, partially offset by increased
administration costs in Corporate."

      Included in the above results, as part of its manufacturing restructuring
plan, the Company recorded a charge, net of tax, of $834,000, or $0.02 per
share, in the third quarter of 2006 compared to a charge, net of tax, of
$655,000, or $0.02 per share, in the third quarter of 2005. For the third
quarter of 2006, these costs were primarily for severance costs related to its
European and Chinese restructuring plans. For the third 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.


      As part of its manufacturing restructuring plan for the first nine months
of 2006, the Company recorded a gain, net of tax, of $2,571,000, or $0.08 per
share, compared to a charge, net of tax, of $1,392,000, or $0.04 per share, in
the first nine months of 2005. In the first nine months of 2006, the Company
benefited from an after-tax gain of approximately $4,100,000, or $0.12 per
share, related to the sale of a building in Italy, which was recorded in the
second quarter of 2006. This benefit was offset by after-tax costs of
approximately $1,529,000, or $0.04 per share, primarily for severance costs
related to the Company's European and Chinese restructuring plans. For the first
nine 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.

      The Company recorded a charge, net of tax, to discontinued operations in
the third quarter of 2006 of $3,137,000, or ($0.09) per share on a diluted
basis. This charge was primarily due to a recent federal appellate court
decision which affirmed that an arbitration panel could decide which deductible
agreements between Watts and Zurich American Insurance Company (Zurich) would
control Zurich's reimbursement claim for defense costs paid in the James Jones
case. As a result of this development, the Company recorded a pre-tax charge of
$5,000,000 in the third quarter of 2006 to provide for a contingency for this
reimbursement claim.
