INSTALLATION INSTRUCTIONS
DIRECT BURIAL
The valve is designed to be buried directly in the pipe trench requiring no concrete or hold down strap installation. The valve must be installed with the septic tank effluent line connected to the valve port marked "IN". The valve ports marked "OUT" are connected to each half of the drainfield.
ADAPTABLE TO VARIOUS PIPES
Each valve port connection is a 4" schedule 40 female slip connection. The riser tube connection is a 4" schedule 40 male slip connection. Use ample pvc, abs, or multi-purpose glue to form a water-tight joint. Any of the following can be used to connect to the Valve:
- Schedule 40 Pvc or Abs Pipe
- Adapter Bushing (Dwv Hub To Sewer & Drain Spigot)
- Astm 2729 (Schedule 30) Coupling
- Bell End Of Astm 2729 (Schedule 30) Pipe

SAMPLE VALVE SPECIFICATION
A non-corrosive alternating valve shall be provided with 4" schedule 40 female connections. The valve plug shall be non-removable, watertight and externally operated. The valve shall be provided with an internal stop mechanism for positioning the plug, and the plug shall be non-jamming when turning from stop. There shall be no metal parts in contact with the wastewater.
The inlet and outlet ports shall be clearly labeled for easy installation and the position of the valve shall be clearly indicated on the top of te valve. At no time shall the operator have contact (physical or visual) with the wastewater. The valve shall be installed in such a manner as to be easily accessible from the ground surface and operated with the standard water meter key provided.
Simple instructions for use and maintenance, printed on durable material, shall be supplied along with each device. The valve shall be the Bull Run Valve.
OPERATION BY WATER METER KEY
A riser cap adapter, a water-tight access cap and valve key are provided. The valve should be buried at such a depth as to allow easy access and operation from the ground surface with the standard water meter key provided.
PUMP SYSTEMS
Effluent pumps can be used to dose the drainfield. The top of the valve is o-ring sealed and pressure tight under normal effluent pump operating conditions. Maximum pressure 25 psi.
The internal plug is tapered to match the valve body seating ribs. This seating mechanism will prevent bypass under minimum head pressure conditions. |
