Zurn Z539 – 12" Heavy-Duty Drain with Deep Sump

A 12" class heavy-duty area drain featuring a Dura-Coated cast-iron body, bottom outlet, seepage pan, and a combination membrane flashing clamp & frame—engineered with a deep sump for increased debris capacity and paired with a heavy-duty slotted grate.

In technical terms, the Zurn Z539 is a 12" top, cast-iron point drain built for harsher conditions and sediment-laden runoff. In plain English: it’s a tough drain that ties cleanly into waterproofing and holds more debris in its deep sump so lines clog less often and clean-outs are faster.

Key Features

  • 12" round top with a heavy-duty, heel-proof slotted grate for reliable inflow under traffic.
  • Deep sump body increases capture volume for sand, fines, and organic debris—reducing downstream clogging.
  • Dura-Coated cast-iron body with bottom outlet for long service life in exposed environments.
  • Seepage pan + combination flashing clamp & frame for clean waterproofing details.
  • Outlet families commonly include NH (No-Hub), NL (Neo-Loc), and IP (Threaded) in 2", 3", 4" sizes (verify per submittal).
  • Top finishes (prefix): Z (cast iron), ZB (polished bronze), ZN (polished nickel-bronze).

Where Z539 Excels

Choose Z539 for parking decks, plazas, ramps, service yards, and light-industrial floors where runoff often carries grit or leaf litter. The deep sump stores debris between clean-outs, and the heavy-duty grate resists rocking in high-traffic zones.

Options & Accessories (Snapshot)

  • -TS top secured; -VP vandal-proof hardware for public areas.
  • -P trap-primer connection; -TC Neo-Loc test cap (for NL outlets).
  • -DG Duresist ductile-iron grate; -AR acid-resist epoxy; -G galvanized coating.

Always confirm final dimensions, loading, outlet availability, and furnish (e.g., bucket options) on the project submittal.

Installation Highlights

1) Set & Anchor

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

2) Tie-In Waterproofing

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

3) Commission & Maintain

Install/secure the grate; schedule regular debris checks—deep sump capacity extends intervals, but pre-storm clean-outs are still best practice.

Case Study: Ramp Runoff with Grit Load

A municipal parking ramp collected sand and fines from winter sanding operations. Replacing standard point drains with Zurn Z539 deep-sump units (3" No-Hub outlets, secured tops) cut downstream jetting calls and shortened maintenance time. The greater sump volume captured seasonal grit, and crews reported faster return-to-service after clean-outs.

Frequently Asked Questions

What’s the advantage of a deep sump?
A deeper sump holds more debris between service visits and reduces the chance of sediment entering the storm line—ideal where runoff carries sand, mulch, or leaf litter.
Which outlet should I specify?
Match to your system: No-Hub (NH) for cast-iron, Neo-Loc (NL) for compression fit, or Threaded (IP) for steel. Common sizes are 2", 3", and 4"; confirm sizes/options on the submittal for your exact SKU.
Is a bucket included?
Deep sump capacity manages debris; a sediment bucket may be furnished or specified depending on configuration. Verify furnish and accessories (e.g., -Y bucket) on the submittal.
