Item 1.01. Entry into a Material Definitive Agreement.

      On February 6, 2007, the Board of Directors of Watts Water Technologies,
Inc. (the "Company") approved changes to the compensation arrangements for
non-employee directors of the Company. A summary of the annual compensation
payable to non-employee directors of the Company effective as of February 6,
2007 is filed as Exhibit 10.1 to this Current Report and is incorporated herein
by reference.

Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal

      The Board of Directors of the Company amended Article IV of the Company's
By-laws (the "By-laws"), effective as of February 5, 2007, to allow for the
issuance of uncertificated shares. By being able to issue uncertificated shares,
the Company may now participate in the Direct Registration System, which is
currently administered by The Depository Trust Company. The Direct Registration
System allows investors to have securities registered in their names without the
issuance of physical certificates and allows investors to electronically
transfer securities to broker-dealers in order to effect transactions without
the risks and delays associated with transferring physical certificates. The
amendment to the By-laws also provides that each registered stockholder shall be
entitled to a stock certificate upon written request to the transfer agent or
registrar of the Company.

      The full text of the By-laws, as amended, is filed as Exhibit 3.1 to this
Current Report, and amended Article IV thereof is incorporated herein by
