The Zurn Z540 is a medium-duty area/floor drain built for balanced performance in commercial and institutional settings. It’s designed to manage surface water effectively while offering durability, ease of installation, and maintenance flexibility.

Key Features

  • Dura-Coated Cast Iron Body with Bottom Outlet & Seepage Pan
    Provides strength and corrosion resistance, while the seepage pan helps manage peripheral flow that might bypass the main grate.

  • Combination Membrane Flashing Clamp & Frame with Sur-Set Bucket
    Integrates waterproofing control and debris capture; the Sur-Set bucket makes maintenance easier without disturbing the drain body.

  • Medium-Duty Slotted Grate (with Material Options)
    Offers adequate flow capacity and load support for many pedestrian or light traffic applications. Top styles are available in cast iron, polished bronze, or polished nickel-bronze to match design needs.

Zurn Z540 – 12" Medium-Duty Drain with Sur-Set Bucket

A 12" class medium-duty area drain combining a Dura-Coated cast-iron body, bottom outlet, seepage pan, and combination membrane flashing clamp & frame—finished with a slotted, heel-proof grate and a furnished Sur-Set sediment bucket for faster maintenance.

In technical terms, the Zurn Z540 is a 12" top, cast-iron point drain with a clamp/frame assembly that ties neatly into waterproofing and helps you fine-tune finish elevation. In plain English: it’s tough, easy to service, and built to keep debris out of your storm line thanks to the included Sur-Set bucket.

Key Features

  • 12" round top with a medium-duty, heel-proof slotted grate for safe, reliable inflow.
  • Dura-Coated cast-iron body with bottom outlet for long service life and straightforward tie-in.
  • Seepage pan + combination flashing clamp & frame for clean waterproofing details.
  • Sur-Set sediment bucket (furnished) to capture grit/leaves and reduce downstream clogging.
  • Outlet families typically include NH (No-Hub), NL (Neo-Loc), and IP (Threaded) in common 2", 3", 4" sizes.
  • Top finishes (prefix): Z (cast iron), ZB (polished bronze), ZN (polished nickel-bronze).

Where Z540 Excels

Use Z540 for plazas, parking decks, ramps, walkways, and light-industrial floors where durability meets architectural finish. The clamp/frame assembly streamlines membrane tie-ins; the furnished Sur-Set bucket shortens clean-out time between storms.

Installation Highlights

1) Locate & Set

Seat the drain body at rough elevation and anchor per detail; verify positive slopes toward the drain across the slab or paver bed.

2) Tie-In Waterproofing

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

3) Commission & Maintain

Install/secure the grate; confirm Sur-Set bucket placement; schedule seasonal clean-outs—especially before heavy rain or freeze-thaw cycles.

Case Study: Plaza Edge Ponding Fix

A retail plaza experienced ponding near curb returns where leaves accumulated each fall. The retrofit added Zurn Z540 drains with 3" No-Hub outlets and secured tops. After the first rainy season, maintenance logs showed faster drawdown and fewer slip-hazard calls; the Sur-Set bucket captured debris before it reached the line, cutting downstream jetting visits roughly in half.

Frequently Asked Questions

What does the Sur-Set bucket do?
It’s a removable debris bucket beneath the grate. It traps sand, leaves, and fines so they don’t clog the line—clean-outs are quicker and downstream maintenance is reduced.
Which outlet connection should I choose?
Match to your piping and detailing: No-Hub (NH) for cast-iron systems, Neo-Loc (NL) for compression fit, or Threaded (IP) for steel. Common sizes are 2", 3", and 4".
Are bronze or nickel-bronze tops available?
Yes—use prefixes ZB (polished bronze) or ZN (polished nickel-bronze) where architectural finish is important; base prefix Z is cast iron.
