The minimum size of any pump or any discharge pipe from a sump having a water closet connected thereto shall be not less than two (2) inches. 3. The discharge line from such ejector, pump or other mechanical device shall be provided with an acasssible back water valve and gate valve and if the gravity drainage line to which such discharge line connects is horizontal, the method of connection shall be from the top through a "wye" branch fitting. 4.

Two (2) fixture units shall be allowed for each gallon per minute of continuous flow. 5.

If constructed of poured concrete, the walls and bottom shall be adequately reinforced and designed to recognized acceptable standards. Metal sumps or tanks shall be of such thickness as to serve their intended purpose and shall be treated internally and externally to resist corrosion. 8. All such sumps and receiving tanks shall be automatically discharged and when in any public use' occupancy shall be provided with dual pumps or ejectors arranged to function independently in case of overload or mechanical failure. The lowest inlet shall have a minimum clearance of twelve (12) inches from the high water or 'starting' level of the sump. 9.
