Description
The Bull Run Valve™ splits and alternates flows to drainfields or systems, increasing the useable life of the septic system. Because the user has zero contact with wastewater (due to the valve’s leak-proof and external operating characteristics) the Bull Run Valve™ is the safest alternating device available. The change from one field to another can be accomplished in less than a minute by merely turning the valve without digging or contact with wastewater.
The Bull Run Valve™ is available in 4″ sch 40 PVC and is suitable wherever disposal systems are used. It is compatible with all gravity drain field products for commercial, industrial, and residential applications.
Engineering Specifications
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 the valve. At no time shall the operator have contact (physical or visu-al) 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.
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 a standard water meter key.
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. The maximum pressure recommended shale not exceed 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.
