Zurn Z662 – 16" Heavy-Duty Drain

A 16" square, heavy-duty area drain combining a Dura-Coated cast-iron body, seepage pan, and a membrane flashing clamp & frame—finished with a traffic-rated slotted grate and suspended sediment bucket for dependable performance on decks, plazas, and industrial floors.

The Zurn Z662 is engineered for exposed environments that demand strength and high inflow. In technical terms, it’s a 16" square-top, Dura-Coated cast-iron drain with bottom outlet, seepage pan, and combination membrane flashing clamp & frame, furnished with a heavy-duty slotted loose grate and a suspended sediment bucket. In everyday language: it ties securely into waterproofing, handles traffic loads, and makes clean-outs straightforward.

  • Heavy-duty slotted loose grate supports traffic loads while admitting flow.
  • Suspended sediment bucket reduces downstream clogging and eases maintenance.

Where Z662 Excels

Specify Z662 for parking decks, ramps, plazas, industrial bays, and garage levels where drains must withstand impact, wheel loads, and weather. The square top pairs well with grid-like joint layouts, and the furnished bucket helps keep systems clear between service intervals.

Specifications at a Glance

Top: 16" square, heavy-duty slotted grate

Body: Dura-Coated cast iron

Outlet: Bottom outlet (3", 4", 6")

Waterproofing: Clamp & frame with seepage pan

Furnished: Suspended sediment bucket

Use: Decks, ramps, plazas, industrial floors

Installation Highlights

1) Set & Secure

Place body to finish elevation; anchor per detail; verify positive slopes toward the drain across the slab.

2) Waterproofing Tie-In

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

3) Commission & Maintain

Install the slotted grate; confirm securement; schedule seasonal clean-outs of the furnished bucket ahead of heavy rain and freeze-thaw cycles.

Case Study: Garage Ramp Low-Point Upgrade

A city garage saw recurring ponding and winter icing at ramp low points. The retrofit standardized on Zurn Z662 drains with 4" No-Hub outlets and secured tops. After one storm season, maintenance logs showed faster runoff capture, fewer freeze-thaw edge failures, and reduced clean-out time thanks to the suspended sediment bucket.

Frequently Asked Questions

What’s the difference between Z662 and Z662-HF?
Both share the same 16" square body and clamp/seepage design. The Z662-HF variant ships with a high-flow ductile iron grate for increased intake during cloudbursts; Z662 uses a heavy-duty slotted grate. Choose based on required inflow and aesthetics.
Which outlet connection should I choose?
Match the outlet to your piping: No-Hub (NH) for cast-iron systems, Threaded (IP) for steel, or Neo-Loc (NL), Inside Caulk (IC), and Inside Gasket (IG) when detailing requires it—available in 3", 4", or 6" sizes.
Is the sediment bucket included?
Yes—Z662 is furnished with a suspended sediment bucket to capture debris and simplify maintenance.
