Zurn Z511 – 9" Heavy-Duty Drain

A compact, 9" heavy-duty area drain designed for traffic-rated use. The Z511 combines a Dura-Coated cast-iron body with bottom outlet, seepage pan, and a combination membrane flashing clamp & frame, topped by a heavy-duty slotted grate for dependable surface capture on decks, ramps, and industrial slabs.

In technical terms, the Z511 integrates neatly with waterproofing and resists impact loads. It’s a tough, serviceable point drain that keeps water moving and maintenance simple in high-traffic hardscapes.

Installation Highlights

1) Set & Anchor

Seat the drain body at rough elevation; anchor per detail; verify positive slope to the drain across slab or paver bed.

2) Waterproofing Tie-In

Integrate the seepage pan and clamp/frame with the membrane; protect the assembly during pours/overlays.

3) Commission & Maintain

Install/secure the grate; add a -Y bucket where leaf/grit load is high; schedule seasonal clean-outs before heavy storms.

Case Study: Entry Ramp with Cart Traffic

A retail loading ramp experienced ponding and top damage from constant cart traffic. The retrofit standardized on Zurn Z511 drains with 3" No-Hub outlets and -TS secured grates. After one rainy season, the team reported faster draw-down and no grate rocking; optional -Y buckets near landscaping cut downstream jetting visits.

Frequently Asked Questions

Which outlet connection should I specify?
Match your system: No-Hub (NH) for cast-iron, Neo-Loc (NL) for compression fit, or Threaded (IP) for steel. Typical sizes are 2", 3", and 4"—confirm on the submittal.
Do I need a sediment bucket?
Use the -Y bucket where debris load (sand, leaves) is high or maintenance intervals are longer. It traps material before it reaches the line and speeds clean-outs.
Are architectural tops available?
Yes—prefix ZB (polished bronze) or ZN (polished nickel-bronze) for finished spaces; base prefix Z is cast iron.
