Sewage Basin Cover Vent

The Zoeller 17-0411 is a structural foam cover designed for sewage basins. It suits installers and maintenance teams who need a reliable vented seal for 2-inch or 3-inch vent pipes. The cover fits basins with a 20-1/2 inch diameter and provides a 1-inch overall height profile.

Poly Structural Foam Build

The cover uses poly structural foam for corrosion resistance in wet environments. Its material handles sewage exposure without rust or rot. The integrated vent accepts both 2-inch and 3-inch piping, reducing the need for separate adapters during installation or retrofit work.

Replaces Damaged Basin Covers

This unit replaces cracked, warped or missing basin covers that allow odours or debris to escape. The jump is worth it when an existing cover fails inspection or no longer seals the basin opening. Buyers who need a non-vented solid lid or a different diameter should verify basin specifications first.

Questions about this item

Does the 2‑inch outlet and 2‑or‑3‑inch vent on the 17‑0411 cap airflow at the basin’s rated capacity?

The cover provides a 2‑inch discharge outlet and accepts either a 2‑inch or 3‑inch vent pipe, matching the basin’s standard venting requirements.

What mounting diameter and clearance does the 20‑1/2‑inch cover need?

It fits a 20‑1/2‑inch basin opening and adds only 1 inch of overall height, so it clears standard riser rings.

How is the structural‑foam cover secured, and what step do installers often miss?

The cover seats on the basin flange and is bolted down; the common miss is forgetting to seal the vent‑pipe grommet before tightening the bolts.
