Zurn Z545 – 16" Diameter Heavy-Duty Drain

A 16" diameter, heavy-duty area drain featuring a Dura-Coated cast-iron body, bottom outlet, seepage pan, and a combination membrane flashing clamp & frame, finished with a heavy-duty slotted grate for robust surface capture on decks, plazas, ramps, and industrial slabs.

In technical terms, the Z545 is a 16" top drain with a rugged cast-iron body, membrane clamp/frame, and seepage pan. In plain language: it ties cleanly into waterproofing, handles traffic and weather, and delivers reliable flow at common hardscape low points.

Key Features

  • 16" round top with heavy-duty slotted grate for high inflow and rugged use.
  • Dura-Coated cast-iron body with bottom outlet for long service life.
  • Seepage pan + combination flashing clamp & frame integrate with waterproofing.
  • Outlet connections (by submittal): IC Inside Caulk, IG Inside Gasket, IP Threaded, NH No-Hub, NL Neo-Loc.
  • Pipe sizes available up to 10" (varies by outlet type).
  • Top finishes (prefix): Z (cast iron), ZB (polished bronze), ZN (polished nickel-bronze).

Where Z545 Excels

Choose Z545 for parking decks, transit platforms, industrial yards, loading docks, and exposed plazas where heavy loads and concentrated runoff coincide. The robust frame resists impact and rocking, while the clamp/frame assembly keeps membrane tie-ins clean and serviceable.

Installation Highlights

1) Set & Anchor

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

2) Waterproofing Tie-In

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 periodic debris checks, especially before heavy rains or freeze-thaw cycles.

Case Study: Distribution-Center Truck Apron

A logistics hub experienced ponding and grate damage at a truck-turning apron. The retrofit standardized on Zurn Z545 drains with 6" No-Hub outlets and -VP secured tops. Post-retrofit inspections recorded faster drawdown during storm surges and fewer grate-shift incidents. The clamp/frame assembly simplified membrane tie-ins where an elastomeric overlay was added at joints.

Frequently Asked Questions

Which outlet connection should I choose?
Match the outlet to your piping and detailing: No-Hub (NH) for cast-iron systems, Threaded (IP) for steel, or Inside Caulk (IC) / Inside Gasket (IG) / Neo-Loc (NL) for specific coordination needs. Pipe sizes vary by outlet family (up to 10" in select types).
How does the clamp & frame help with waterproofing?
It provides a mechanical seal point that integrates the membrane with the drain body while allowing the grate/frame to sit flush with finished grade—useful under overlays, toppings, or pavers.
What’s the open area of the grate?
Z545 offers approximately 45 in² of open area by grate (verify exact value and configuration on the submittal for your outlet/size).
