Item 8.01. Other Events.

On November 9, 2007, Watts Water Technologies, Inc. (the "Registrant") issued a
press release announcing that the Board of Directors authorized the Registrant
to repurchase shares of its Class A Common Stock. A copy of the press release is
attached hereto as Exhibit 99.1 and incorporated herein by reference.

On November 15, 2007, the Registrant adopted a written trading plan under Rule
10b5-1 of the Securities Exchange Act of 1934, as amended. The Registrant
implemented this written trading plan in connection with its share repurchase
program. Adopting a trading plan that satisfies the conditions of Rule 10b5-1
allows a company to repurchase its shares at times when it might otherwise be
prevented from doing so due to self-imposed trading blackout periods or pursuant
to insider trading laws. A broker selected by the Registrant will have the
authority under the terms and limitations specified in the plan to repurchase
shares on the Registrant's behalf in accordance with the terms of the plan.

Information regarding share repurchases will be available in the Registrant's
periodic reports on Form 10-K and 10-Q filed with the Securities and Exchange

Item 9.01. Financial Statements and Exhibits

undersigned hereunto duly authorized.
