Item 5.02.                                         Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On October 31, 2011, the Board of Directors of Watts Water Technologies, Inc. (the “Company”) approved amendments to the Company’s Pension Plan (the “Pension Plan”) and Supplemental Employees Retirement Plan (the “SERP”) to cease benefit accruals under both the Pension Plan and the SERP effective December 31, 2011.  As a result of these amendments, employees who participate in the Pension Plan or the SERP will not earn additional pension benefits for pay or service under either plan after December 31, 2011.

The eligibility and vesting provisions applicable to benefits accrued through December 31, 2011 and the optional forms of payments under the Pension Plan and SERP will not change.  Although service after December 31, 2011 will not result in additional benefits under the Pension Plan and SERP, service after December 31, 2011 will be counted for purposes of vesting and retirement eligibility under the plans, and service during 2012 will also be counted towards satisfying the one-year requirement for participation in the Pension Plan for employees hired during 2011.

In connection with the amendments to the Pension Plan and SERP, effective January 1, 2012 the Company’s 401(k) Savings Plan will be amended to add an enhanced match and non-elective core contribution.
