Installation Steps
1. Spider Valve
®
assembly must be
installed at the high point of the system
such that the effluent will gravity drain
from the valve to the disposal trenches.
Consult site plan and Figure 1.
2. At least 3' of distal pressure should be
maintained on the manifold to ensure
proper effluent splitting.
