Zurn Z533 – 9" Heavy-Duty Parking Deck Drain with Support Flange

A compact, heavy-duty deck drain with a Dura-Coated cast-iron body, gasketed support flange, and traffic-rated slotted grate—built for exposed garages, ramps, and plazas.

The Zurn Z533 is a 9" diameter parking deck drain designed for reliable surface capture under vehicular traffic. In technical terms, it combines a Dura-Coated cast-iron body with a bottom outlet, a heavy-duty gasketed drain support flange, and a heavy-duty (Duresist) slotted grate— it anchors firmly to the slab, ties cleanly into the deck membrane, and handles runoff without deforming.

Key Features

  • 9" round top sized for concentrated collection points on decks.
  • Dura-Coated cast-iron body with bottom outlet for long service life.
  • Heavy-duty gasketed support flange for anchorage and membrane tie-in.
  • Heavy-duty Duresist slotted grate engineered for vehicular loads.
  • Multiple outlet sizes & connection types (e.g., No-Hub), easing tie-in to existing piping.

(Features per Zurn product literature and distributor specs.)

Where Z533 Excels

Use the Z533 on top decks, ramps, precast garage levels, and plaza surfaces where drains must resist impact, traffic, and weather. The gasketed flange helps create a robust, watertight interface with deck membranes; the compact 9" top is ideal for point drains at low spots and scuppers.

Case Study: Downtown Garage Low-Point Fix

A downtown garage experienced recurring ponding at ramp transitions. The retrofit specified Zurn Z533 drains with No-Hub outlets at low points. The 9" tops improved surface capture without altering the structural slab, and the gasketed flange simplified membrane detailing. After one storm season, maintenance logs reported faster drainage and fewer freeze-thaw issues at joints.

Frequently Asked Questions

What does the support flange do?
It anchors the drain to the slab and provides a gasketed interface to the deck’s waterproofing, reducing leak risk at the penetration.
Is the grate traffic-rated?
Yes. The heavy-duty slotted (Duresist) grate is engineered for vehicular areas typical of parking decks and ramps.
What outlet options are available?
Z533 is offered in multiple outlet sizes and connection types (e.g., No-Hub). Check the project submittal for the exact configuration required.
