4.2 Installation Steps
- Prepare the Basin: Ensure the top rim of the sewage basin is clean and free of debris.
- Position the Cover: Carefully place the 17-0411 cover onto the basin. Align the pre-drilled holes on the cover with the corresponding holes or mounting points on your sewage basin. The cover is designed to accommodate 2-inch or 3-inch vent pipes and a 2-inch outlet.

- Connect Pipes: Insert the vent pipe(s) and discharge pipe through their respective openings in the cover. Ensure proper sealing around these pipe penetrations to prevent gas escape and water ingress.

5. Operating Instructions
The Zoeller 17-0411 Sewage Basin Cover is a passive component designed to maintain a sealed environment for your sewage basin. Once properly installed, no active operation is required from the cover itself.
- Ensure the cover remains securely fastened at all times.
- Periodically inspect the vent and discharge pipe connections to confirm they remain sealed and free of obstructions.
- The cover's primary function is to contain odors and prevent foreign objects from entering the basin, while allowing necessary ventilation and discharge.
6. Maintenance
Regular maintenance helps ensure the longevity and effectiveness of your sewage basin cover.
- Visual Inspection: Annually inspect the cover for any signs of damage, cracks, or warping. Check the integrity of the seals around pipe penetrations and the basin rim.
- Cleaning: Clean the exterior of the cover as needed with mild soap and water. Avoid harsh chemicals that could degrade the polyethylene material.
- Fastener Check: Periodically check that all fasteners securing the cover are tight. Retighten if necessary, but do not overtighten.
- Ventilation: Ensure the vent pipe opening remains clear and unobstructed to allow for proper air exchange and prevent vacuum lock or pressure buildup.
7. Troubleshooting
Most issues related to the basin cover are minor and can be resolved with simple checks.
7.1 Odor Emission
- Cause: Improper seal around the basin rim or pipe penetrations.
- Solution: Inspect all fastening points and pipe connections. Ensure fasteners are tight and apply appropriate sealant if gaps are present. Check for cracks in the cover itself.
7.2 Water Leakage
- Cause: Loose fasteners, damaged seal, or improper pipe connections.
- Solution: Tighten all fasteners. Inspect and replace any damaged seals. Ensure pipe connections are watertight.
7.3 Cover Does Not Sit Flush
- Cause: Debris on the basin rim, warped basin, or incorrect cover size.
- Solution: Clean the basin rim thoroughly. If the basin is warped, it may need repair or replacement. Verify that the cover diameter matches your basin (this cover is 20-1/2 inches in diameter).
