Zurn Z534 – 12" Heavy-Duty Parking Deck Drain with Support Flange

A rugged, round parking deck drain that pairs a Dura-Coated cast-iron body, support flange, and heavy-duty slotted grate to move stormwater fast on exposed decks and ramps.

The Zurn Z534 is engineered for top decks, ramps, and open garages that see heavy traffic and harsh weather. In technical terms, it’s a 12" (approx. 12-1/4") heavy-duty parking deck drain with a bottom outlet, heavy-duty gasketed support flange, and a heavy-duty slotted grate—in plain English, it anchors solidly to the slab, ties cleanly into the waterproofing, and stands up to vehicles while collecting runoff efficiently.

Key Features

  • 12" class drain head (approx. 12-1/4" top) sized for deck runoff capture.
  • Dura-Coated cast-iron body with bottom outlet for robust service life.
  • Heavy-duty gasketed support flange anchors to slab and interfaces with waterproofing.
  • Heavy-duty slotted grate admits water while resisting deformation under traffic.
  • Top material options available (cast iron, bronze, nickel-bronze by prefix) to match project specs.

Where Z534 Excels

Use the Z534 on top decks, ramps, plazas, and exposed garage levels where drains must endure vehicle loads, impact, and temperature swings. The wide support flange simplifies tie-in to deck membranes and overlays, helping reduce leak risk at the penetration.

Sizing & Options (Snapshot)

  • Nominal top: 12" (≈12-1/4" overall)
  • Outlet types: No-Hub, Neo-Loc, Inside Caulk/Inside Gasket, Threaded (per submittal)

Specifications at a Glance

Top: 12" round, heavy-duty slotted grate

Body: Dura-Coated cast iron

Flange: Heavy-duty, gasketed support flange

Outlet: Bottom outlet (sizes & types per submittal)

Use: Parking decks, ramps, exposed garages

Options: Sediment bucket, secured/locking tops, heel-proof variation

Installation Highlights

1) Set & Secure

Set body to elevation; anchor via the support flange; verify positive drainage slopes across the deck.

2) Waterproofing Interface

Tie the gasketed flange to the deck membrane per details; protect the drain during pours/overlays and re-surfacing.

3) Commission & Maintain

Install/secure the top assembly; add sediment bucket if specified; schedule seasonal clean-outs ahead of heavy rain and freeze-thaw cycles.

Case Study: Mixed-Use Garage Top-Deck Resurfacing

A mixed-use garage struggled with ponding near expansion joints and drain locations. The retrofit replaced undersized drains with Zurn Z534 units. The 12" tops improved surface capture, while the support flange simplified the membrane interface. After one storm season, maintenance logs showed faster drainage, fewer freeze-thaw issues, and no grate-related trip incidents—while inspection time dropped thanks to standardized components.

Frequently Asked Questions

What does the support flange do?
It provides structural bearing/anchorage and a gasketed interface to the waterproofing—helping reduce leak risk at the drain penetration and easing installation in precast decks.
Is a heel-proof grate available?
Yes. A heel-proof variation (HP) is offered where tighter slot geometry is required near pedestrian paths; confirm selection on the submittal.
Which outlet styles can I specify?
Common options include No-Hub and Neo-Loc, with Inside Caulk/Inside Gasket or Threaded available for certain sizes. Always verify the outlet type and size against the project specification sheet.
