ITEM 5. Other Events and Required FD Disclosure

        On May 19, 2003, Timothy P. Horne, a member of the Board of Directors of
Watts Industries, Inc. (the "Company"), the controlling stockholder of the
Company, and its former Chief Executive Officer, President and Chairman,
established three pre-arranged plans to sell shares of class A common stock, par
value $.10 per share, of the Company ("Class A Common Stock") in accordance with
Rule 10b5-1 under the Securities Exchange Act of 1934. Mr. Horne's plans provide
that over a six month period, up to 239,611 shares of Class A Common Stock may
be sold.

        Mr. Horne also instituted 10b5-1 trading plans in his capacity as
trustee of certain trusts for the benefit of Horne family members, which provide
in the aggregate for the sale of up to 180,000 shares of Class A Common Stock
over a six month period.

        Rule 10b5-1 permits insiders to implement a written plan to sell stock
when they are not aware of material non-public information and continue to sell
shares in accordance with the predetermined plan, even if they subsequently
become aware of such information.


      Pursuant to the requirements of the Securities Exchange Act of 1934, the
Registrant has duly caused this report to be signed on its behalf by the
undersigned hereunto duly authorized.

                                         WATTS INDUSTRIES, INC.
