Spider Valve® The Zoeller Spider Valve® assembly is used to split pressurized effluent to a gravity disposal field. A pump is placed after the septic tank to pressurize the Spider Valve®. The Spider Valve® manifold assembly can then split the effluent evenly from 2 lines up to 10 lines. The Spider manifold should be installed at the highest elevation in the system. From there 1 ¼′′ diameter gravity discharge lines direct the effluent to the individual disposal trenches, if your local code will allow. This allows for a more profitable installation verses running 4′′ diameter lines
from the Spider Valve® to the trenches. The manifold can be configured to use on systems that have unequal length trenches. Flow control washers are available without holes for field drilling (unequal length lines) or with 1/4′′ diameter holes for equal length lines. 1/4′′ holes provide 1.65 GPM per outlet at 5′ of distal pressure. This allows the use of a Zoeller STEP system in your primary septic tank instead of an extra pump tank (check local codes). The Zoeller Spider Valve® assembly is the economical answer to your needs for equal effluent distribution.
For Additional Information
Bull Run Valve® The Bull Run Valve is designed to direct flow to septic fields or systems. In addition to the advantages of longer life and easier installation, the Bull Run Valve is an extremely health safe device installation, the Bull Run Valve is an extremely health safe device available for alternating wastewater disposal applications. The user has absolutely no contact with wastewater due to the valve′s leak proof and external operating characteristics. The changeover from one drain age field to another can be accomplished in less than a minute without digging or contact with wastewater by simply turning a valve. The Bull Run Valve is available in 4′′ diameter pipe and is suitable wherever septic disposal systems are used in commercial, industrial, and residential applications. Operating the Valve: The Direction control handle should be rotated periodically to direct effluent to one or the other two septic fields.
