Step 2. Install Tank Adapters and Risers, cont.
Key Points:
• Watertight seams and penetrations are critical for proper performance.
• Before installing the risers, make sure that:
– All risers are the correct height. Recommended riser height is
2in (50mm) above final grade.
– All risers are being installed in their correct locations.
– All penetrations are at the correct height for the connections.
– All penetrations are aligned correctly for good pump package access.
• After installing the risers, make sure that:
– All adhesive seams are free of voids, with smooth, continuous fillets.
– The adhesive is set before backfilling or testing watertightness.
Step 3. Test Tank and Adapter Seams for Watertightness
Test the tank and the tank-to-riser seams for watertightness. Follow the
manufacturer’s instructions.
• Some manufacturers require a partial or full backfill around the tank
before testing watertightness.
• Use NIN-RLA-RR-1,
PVC Access Riser Installation Instructions
to test the
seams between the access riser, tank adapter, and tank for watertightness.
Key Points:
• Plug the tank’s inlet and outlet before testing watertightness.
• Fill the tank with water to a level 2in (50mm) into the riser.
• All seams between the tank and access riser must pass the watertightness
test before you continue.
• Follow all applicable regulations for watertightness testing.
Step 4. Install Biotube Pump Package
Install the pumping components from a Biotube pump package into the
interceptor/septic tank.
Step 4a:
Install a Biotube pump vault and Biotube effluent filter.
• For Biotube pump vaults, see NIN-PVU-1,

.
• For PVP-series Biotube pump vaults, see NIN-PVU-3,
Pump Vault Installation Instructions
Key Point:
Pump vault placement and orientation is important – it
affects the location of the pump, discharge assembly, and splice box.
Fill the tank to a
level 2in (50mm)
into the riser.
