Installation Steps

1. Spider Valve® assembly must be

1/2" FLEX PIPE

installed at the high point of the system

such that the efuent 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

Installation Steps, continued

3. For distribution systems with unequal length disposal trench lines, use the chart provided to determine the

correct ow rate for the diameter hole that must be eld drilled in the ow control washer. Install washers

into the unions as shown in Figure 2.

4. For distribution systems with equal length disposal trenches then drill 1/4" diameter holes (or larger) in all washers.

5. The manifold should be installed in a 24" or 30" diameter access riser with lid.

6. Bed manifold area with 2" of pea gravel. Manifold should be installed level.

7. The incoming line should be pressurized with at least 3' of distal pressure. The manifold should be
connected to the pump line with a 2" union PVC pipe connection.

8. Outlet pipes contain 3' of exible PVC pipe with a 1-1/4" diameter connection. Run 1-1/4" or larger pipe

away and downgrade from manifold to individual trenches (check local codes).

9. Check that all connections are glued appropriately and watertight. Backll around manifold with pea gravel

until 2" pipe is almost buried. This will ensure the manifold does not move and stays close to level.

10. Place access riser and lid around manifold and nish backlling. Landscape as desired.

Maintenance Instructions

The Spider Valve should be inspected and maintained as needed during routine maintenance inspections of the
system. Please follow the steps below to properly inspect and maintain the Spider Valve.

1. Please wear appropriate safety apparel and equipment when maintaining any wastewater component or system.

2. Remove the riser lid to access the Spider Valve.

3. Locate the 1/2” PVC union connections (see gure 2) and unscrew them one at a time to inspect the ow
control washer orices for debris or obstructions. NOTE: It is important to inspect one union and ow
control washer at a time so that ow control washers with different orice diameters are not mistakenly

installed within an incorrect union.

4. If the orice is obstructed, remove the ow control washer and use a nylon blush to clean it with water.

5. Reinstall the ow control washer within the correct union and reassemble.

6. Repeat steps 3-5 with each union until all have been inspected and cleaned as necessary.

All Clarus Environmental products must be installed and maintained in accordance with all applicable codes.
