(hereinafter called the "Corporation"), a corporation organized and existing under the General Corporation Law of the State of Delaware, the Certificate of Incorporation of which was filed  in the Office of the Secretary of Slate of Delaware on December 27, 1985 and recorded in the Office of the Recorder of Deeds of New Castle County, State of Delaware, on December 27, 1985, which Certificate of Incorporation was amended pursuant to a Certificate of Amendment  filed in the Office of the Secretary of State of Delaware on June 13, 1986 and recorded  in the Office of the Recorder of Deeds of New Castle County, State of Delaware, on June 18, 1986, does hereby certify that this Restated Certificate of Incorporation has been duly adopted pursuant to Sections 242 and 245 of the General Corporation Law of the State of Delaware. FIRST:The name of the Corporation is Watts Industries, Inc. SECOND: The address of the Corporation's registered office in the State of Delaware is 1209 Orange Street in the City of Wilmington, County of New Castle. The name of its registered agent at such address is The Corporation Trust Company, 1209 Orange Street, Wilmington, Delaware. THIRD:The nature of the business or purpose to be conducted or promoted is as follows: To conduct or engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware. FOURTH:The total number of shares of capital stock which the Corporation shall have authority to issue shall be Thirty-eight million (38,000,000) shares, of which twenty million (20,000,000) shall be Class A Common Stock, par value $.10 per share ("Class A Common Stock"), thirteen million (13,000,000) shall be Class B Common Stock, par value $.10 per share ("Class B Common Stock"), and five million (5,000,000) shall be Preferred Stock, par value $.10 per share, issuable in series ("Preferred Stock"). 00002

As of the date and time this Restated Certificate of Incorporation  shall become effective under the laws of the State of Delaware (the "Effective Time"), each share of Common Stock, par value $1.00 per share ("Old Common Stock"), issued and outstanding  immediately prior to the Effective Time shall be automatically converted (without any further act) into 330 fully paid and non-assessable shares of Class B Common Stock, each share of Class B Common Stock, par value $1.00 per share ("Old Class B Stock"), issued and outstanding immediately prior to the Effective Time shall be automatically converted (without any further act) into 330 fully paid and non-assessable shares of Class A Common Stock, and each share of 10% Preferred Stock, par value $100.00 per share ("Old Preferred Stock"), issued and outstanding immediately prior to the Effective Time shall be automatically converted (without any further act) into such number of fully paid and non-assessable shares of Class B  Common Stock as is equal to a fraction, the numerator of which shall equal 100 plus the number which is equal to the dollar value of all accrued and unpaid dividends, if any, on such  share and the denominator of which shall be 16.5; provided, however, that no fractional shares shall be issued on account of such conversion of Old Preferred Stock and that cash shall be paid in lieu thereof. Until presented and surrendered for cancellation, each certificate for shares of the Old Common Stock, Old Class B Stock and Old Preferred Stock, respectively, outstanding as of the Effective Time shall be deemed to represent the number of shares of Class A Common Stock Class B Common Stock determined in accordance with this paragraph, and upon such presentation and surrender each holder of a certificate or certificates for such Old Common Stock, Old Class B Stock or Old Preferred Stock, as applicable, shall be entitled to receive a certificate for such number or shares of Class A Common Stock or Class B Common Stock. Except as otherwise specifically stated in this Article Fourth, shares of Class A Common Stock and shares of Preferred Stock may be issued by the Corporation from time to time as approved by its Board of Directors without the approval of the stockholders. Subsequent to the Effective Time, no shares of Class B Common Stock may be issued by the Board of Directors without the prior approval of a majority in interest of the holders of Class B Common Stock and the Class A Common Stock, voting as separate classes, except as provided in Sections A.3 and A.4 of this Article Fourth. The consideration for the issuance of shares shall be paid in full before their issuance and shall not be less than the par value per share. The consideration for the shares shall be such consideration as is lawful under the General Corporation Law of the State of Delaware at the time of issue, and the value of such property, labor or services, as determined by the Board of Directors of 00003 2

the Corporation, shall be conclusive. Upon payment of such consideration, such shares shall be deemed to be fully paid and non-assessable. In the case of a stock dividend, that part of the surplus or retained earnings of the Corporation which is transferred to stated capital upon the issuance of shares as a share dividend shall be deemed to be the consideration for such issuance. A description of the different classes of the Corporation's capital stock and a statement of the powers, designations, preferences and relative, participating, optional or other specified rights of each class of capital stock or series thereof and the qualifications, limitations or restrictions appertaining thereto are as follows: A. Class A Common Stock and Class B Common Stock. 1. Voting. (a) At every meeting of the stockholders of the Corporation (or with respect to any action by written consent in lieu of a meeting of stockholders), each share of Class A Common Stock shall be entitled to one (1) vote (whether voted in person by the holder thereof or by proxy or pursuant to a stockholders' consent) and each share of Class B Common Stock shall be entitled to ten (10) votes (whether voted in person by the holder thereof or by proxy or pursuant to a stockholders' consent), voting together as one class on all matters which may lawfully be submitted to a vote of stockholders, except to the extent otherwise required by law and except as otherwise provided in this Restated Certificate of Incorporation or any amendment hereof. (b) In determining whether any resolution has been adopted by the vote of a specified  percentage of the holders of shares of the Corporation pursuant to the Corporation's  By-laws or otherwise, such percentage shall be calculated as a percentage of the total number of votes entitled to be cast by the holders of the Class A Common Stock and the Class B Common Stock (and any other shares entitled to vote thereon) except to the extent such holders vote as separate classes as required by law or as otherwise provided in this Restated Certificate of Incorporation. 2. Conversion. (a) Each share of Class B Common Stock may at any time be converted into one (1) fully paid and non-assessable share of Class A Common Stock. Such 00004 3

conversion right shall be exercised by the surrender of the certificate representing such share of Class B Common Stock to be converted by the record holder thereof at any time during normal business hours at the principal executive offices of the Corporation or, if an agent for the registration of the transfer of shares of Class A Common Stock is then duly appointed and acting (the "Transfer Agent"), then at the office of the Transfer Agent, accompanied by a written notice of the election by the record holder thereof to convert, and (if so required by the Corporation or the Transfer Agent) by instruments of transfer, in form satisfactory to the Corporation or the Transfer Agent. A conversion shall be deemed to have occurred at the close of business on the date when the Corporation or the Transfer Agent has received the prescribed written notice, the required certificate or certificates and any such instruments of transfer; provided, however, that any such conversions within five (5) business days after the Effective Time shall be deemed to have occurred at the time the Corporation or Transfer Agent, as applicable, receives all such documentation in proper form. The Corporation or the Transfer Agent shall deliver a certificate or certificates representing the shares of Class A Common Stock issuable upon such conversion to the record holder requesting such conversion as soon as practicable thereafter. Any such conversion shall be made without charge for any stamp or similar tax  in respect of the issuance of the certificate or certificates for the shares of Class A Common Stock issued in connection with such conversion, unless such certificate or certificates are to be issued in a name other than that of the record holder of the share or shares of Class B Common Stock converted, in which case such record holder shall pay to the Corporation or the Transfer Agent the amount of any stamp or similar tax which may be payable in respect of any transfer involved in such conversion. (b) The Corporation shall not be required to convert Class B Common Stock and no surrender of Class B Common Stock shall be effective for that purpose while the stock transfer books of the Corporation are closed for any purpose; but the valid presentation of Class B Common Stock for conversion during any period such books are so closed shall become effective for conversion immediately upon the re-opening  of such books, as if the conversion had been made on the date such Class B Common Stock was surrendered.  (c) The Corporation covenants that it will at all times reserve and keep available, solely for the purpose of issuance upon conversion of the outstanding shares of 00005 4

Class B Common Stock, such number of shares of Class A Common Stock as shall be issuable upon the conversion of all such outstanding shares, provided that nothing contained herein shall be construed to preclude the Corporation from satisfying its obligations in respect of the conversion of the outstanding shares of Class B Common Stock by delivery of shares of Class A Common Stock which are held in the treasury of the Corporation. The Corporation covenants that if any shares of Class A Common Stock required to be reserved for purposes of conversion hereunder require registration with or approval of any governmental authority under any federal or state law before such shares of Class A Common Stock may be issued upon conversion, the Corporation will use its best efforts to cause such shares to be duly registered or approved, as the case may be. The Corporation will endeavor to list the shares of Class A Common Stock required to be delivered upon conversion prior to such delivery upon each national securities exchange or listing service, if any, upon which the outstanding Class A Common Stock is listed at the time of such delivery. The Corporation covenants that all shares of Class A Common Stock which shall be issued upon conversion of the shares of Class B Common Stock, will, upon issuance, be fully paid and non-assessable and not entitled to any preemptive rights. (d)At such time as the total number of shares of Class B Common Stock issued and outstanding shall constitute less than five percent (5%) of the aggregate number of shares of Class A Common Stock and Class B Common Stock issued and outstanding, all of the outstanding shares of Class B Common Stock shall be automatically converted (without any further act) into an equal number of shares of Class A Common Stock pursuant to the terms of this Section A.2. Such conversion shall be deemed to be effective at such time, regardless of whether the certificate or certificates for such outstanding shares of Class B Common Stock shall have been duly surrendered for conversion. (e)All shares of Class B Common Stock converted pursuant to this Section A.2 shall thereupon be retired and revert to the status of authorized and unissued shares, and may not be reissued except as provided in Section A.3 or A.4 of this Article Fourth.  3.Further Issuance and Authorization of Class B Common Stock. Following the Effective Time, no additional shares of Class B Common Stock shall be issued or authorized without 00006 5

the affirmative vote of a majority of all votes entitled to be cast by the holders of the Class A Common Stock and Class B Common Stock, voting as separate classes, except as provided in Section A.4 of this Article Fourth.  4. Dividends.  Dividends may be declared by the Board of Directors upon and paid to the holders of the Class A Common Stock and Class B Common Stock out of funds legally available therefor; provided, however, that such dividends, when, as and if declared and paid, shall be so declared and paid to such holders pro rata according to the number of shares of Class A Common Stock and Class B Common Stock held by each such holder (with the number of shares of outstanding  Class A Common Stock and Class B Common Stock being aggregated and considered a single class for this purpose); and provided further, however, that no dividend or other distribution may be declared upon the Class A Common Stock, whether  payable in cash or in shares of Class A  Common Stock or otherwise, unless a comparable dividend shall be declared upon the Class B Common Stock and vice versa. If the dividend declared upon the Class A Common Stock is payable in shares of Class A Common Stock, the comparable dividend declared upon the Class B Common Stock shall be payable in shares of Class B Common Stock, and vice versa. No dividend declared on shares of Class A Common Stock shall be payable in shares of Class B Common Stock, and vice versa.  5. Stock Splits and Other Transactions. Shares of Class A Common Stock or Class B Common Stock may not be split up, subdivided, 'combined or reclassified, unless at the same time the shares of such other class are proportionately so split up, subdivided, combined or reclassified in a manner which maintains the same proportionate equity ownership (i.e., the same proportion  of shares of Class A Common Stock and Class B Common Stock held by each class) between the holders of Class A Common Stock and Class B Common Stock as comprised on the record date for any such transaction. 6. Liquidation Rights.  In the event of a liquidation or dissolution of the Corporation, or a winding up of its affairs, whether voluntary or involuntary, or a merger or consolidation of the Corporation, after payment or provision for payment of the debts or liabilities of the Corporation and the amounts to which holders of Preferred Stock, if any, may be entitled, holders of Class A Common Stock and Class B  00007 6

Common Stock shall be entitled to share ratably as one class for this purpose (i.e., an equal amount of assets for each share of either Class A Common Stock or Class B Common Stock) in the remaining assets of the Corporation. 7. Restriction on Transfer of Class B Common Stock. (a) No person holding shares of Class B Common Stock of record (hereinafter called a "Class B Holder") may transfer, and the Corporation shall not register the transfer of, such shares of Class B Common Stock, whether by sale, assignment, gift, bequest, appointment or otherwise, except to a Permitted Transferee (as hereinafter defined). A Permitted Transferee shall mean, with respect to each person from time to time shown as the record holder of shares of Class B Common Stock, as follows:  (i)In the case of a Class B Holder who is a natural person, a Permitted Transferee shall mean: (A) The spouse of such Class B Holder, any lineal descendant of a grandparent of such Class B Holder, and any spouse of such lineal descendant (which lineal descendants, their spouses, the Class B Holder, and his or her spouse are herein collectively referred to as the "Class B Holder's Family Members");  (B) The trustee of a trust for the benefit of such Class B Holder and/or one or more of his or her Permitted Transferees described in each subclause of this clause (i) other than this subclause (B), provided that such trust may also grant a general or special power of appointment to one or more of such Class B Holder's Family Members and may permit trust assets to be used to pay taxes, legacies and other obligations of the trust or of the estates of one or more of such Class B Holder's Family Members payable by reason of the death of any of such Family Members;  (C) A corporation of which all of the beneficial ownership of outstanding capital stock entitled to vote for the election of directors is owned by, or a partnership of which all of the beneficial ownership of the partnership interests entitled to participate in the management of the partnership are held by, the Class B Holder or his or her Permitted Transferees determined under this clause (i), provided that if by reason of any change in the ownership of such stock or partnership interests, such corporation or  00008  7

partnership would no longer qualify as a Permitted Transferee, all shares of Class B Common Stock then held by such corporation or partnership shall, upon the election of the Corporation given by written notice to such corporation or partnership, without further act on anyone's part, be converted into shares of Class A Common Stock effective upon the date of the giving of such notice, and stock certificates formerly representing such shares of Class B Common Stock shall thereupon and thereafter be deemed to represent the like number of shares of Class A Common Stock; (D) The estate of such Class B Holder; and (E) The trustee or trustees of a voting trust established by one or more Class B Holders and/or one or more of his or her Permitted Transferees described in each subclause of this clause (i) other than this subclause (E). (ii) In the case of a Class B Holder holding the shares of Class B Common Stock in question as trustee pursuant to a trust (including a voting trust) other than an irrevocable trust as provided in subsection (iii) below, "Permitted Transferee" means (A) any person who originally transferred such Class B Common Stock to such trust and (B) any Permitted Transferee of any such transferor determined pursuant to clause (i) above. (iii) In the case of a Class B Holder holding the shares of Class B Common Stock in question as trustee pursuant to a trust which is irrevocable, “permitted Transferee” means (A) any person to whom or for whose benefit principal may be distributed either during or at the end of the term of such trust whether by power of appointment or otherwise and (B) any Permitted Transferee of any such person determined pursuant to clause (i) above.

(v) In the case of a Class B Holder which is the  00009 8

estate of a deceased Class B Holder, or which is the estate of a bankrupt or insolvent Class B Holder, which holds record and beneficial ownership of the shares of Class B Common Stock in question, "Permitted Transferee" means a Permitted Transferee of such deceased, bankrupt or insolvent Class B Holder as determined pursuant to clause (i), (ii), (iii) or (iv) above, as the case may be.  (b) Notwithstanding anything to the contrary set forth herein, any Class B Holder may pledge such Holder's shares of Class B Common Stock to a pledge pursuant to a bona fide pledge of such shares as collateral security for indebtedness due to the pledgee, provided that such shares shall not be transferred to, or registered in, the name of the pledgee and shall remain subject to the provisions of this Section A.7. In the event of foreclosure or other similar action by the pledgee, such pledged shares of Class B Common Stock may only be transferred to a Permitted Transferee of the pledgor or converted into shares of Class A Common Stock, as the pledgee may elect.  (c) For purposes of this Section A.7: (i) The relationship of any person that is derived by or through legal adoption shall be considered a natural one.  (ii) Each joint owner of shares of Class B Common Stock shall be considered a "Class B Holder" of such shares.  (iii) A minor for whom shares of Class B Common Stock are held pursuant to a Uniform Gifts to Minors Act or similar law shall be considered a Class B Holder of such shares.  (iv) Unless otherwise specified, the term "person" means both natural persons and legal entities.  (v) Without derogating from the election conferred upon the Corporation pursuant to subclause (C) of clause (i) above, each reference to a corporation shall include any successor corporation resulting from merger or consolidation; and each reference to a partnership shall include any successor partnership resulting from the death, admission or withdrawal of a partner.  (d) Any transfer of shares of Class B Common Stock not permitted hereunder shall result in the automatic conversion of those shares of Class B Common Stock into an 00010 9

The Corporation may, in connection with preparing a list of stockholders entitled to vote at any meeting of stockholders, or as a condition to the transfer or the registration of shares of Class B Common Stock on the Corporation's books, require the furnishing of such affidavits or other proof as it deems necessary to establish that any person is the beneficial owner of shares of Class B Common Stock or is a Permitted Transferee.
