Zurn Z550 – 9" Diameter Medium-Duty Drain

A 9" round, medium-duty area drain built around a Dura-Coated cast-iron body with a bottom outlet, seepage pan, and combination membrane flashing clamp & frame—topped by a slotted, heel-proof grate for dependable surface capture on plazas, decks, and garage levels.

In technical terms, the Zurn Z550 is a coated cast-iron point drain with a clamp/frame assembly that ties neatly into waterproofing systems. In plain English: it’s a tough, low-maintenance drain that’s easy to service and sized right for common hardscape low-points.

Key Features

  • 9" round top with medium-duty heel-proof slotted grate for safe, reliable inflow.
  • Dura-Coated cast-iron body with bottom outlet for long service life.
  • Seepage pan + combination flashing clamp & frame to simplify membrane tie-in.
  • Outlet choices typically include NH (No-Hub), NL (Neo-Loc), and IP (Threaded) in common 2", 3", and 4" sizes.
  • Top finishes by prefix: Z (cast iron), ZB (polished bronze), ZN (polished nickel-bronze).

Where Z550 Excels

Specify Z550 for plazas, parking decks, ramps, walkways, and light-industrial floors where durability, service access, and clean waterproofing details matter. The round grate resists rocking under foot and cart traffic, while the clamp/frame assembly makes it easier to coordinate with toppings or pavers.

Popular Options (Snapshot)

  • -TS top secured; -VP vandal-proof hardware.
  • -DG Duresist grate for harsher duty; -AR acid-resist epoxy; -G galvanized.
  • -Y sediment bucket; -P trap-primer connection; -TC Neo-Loc test cap (NL outlets).

Installation Highlights

1) Set & Elevate

Place the body to rough elevation; ensure positive slope toward the drain across slab or pavers.

2) Tie Into Waterproofing

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

3) Commission & Maintain

Install/secure the grate; add a -Y bucket if specified; schedule debris checks before heavy rain or freeze-thaw cycles.

Case Study: Retail Deck Low-Point Fix

A two-level retail deck experienced nuisance ponding near expansion joints and curb returns. The engineer standardized on Zurn Z550 drains with 3" No-Hub outlets and -TS secured tops. After a full rainy season, facility logs showed faster drawdown, fewer slip-hazard calls, and shorter clean-out windows. Where landscaping bordered the deck, adding -Y buckets reduced downstream jetting visits.

Frequently Asked Questions

Which outlet connection should I specify?
Match to your piping and detailing: No-Hub (NH) for cast-iron systems, Neo-Loc (NL) for compression fit, or Threaded (IP) for steel. Most Z550 configurations are available in 2", 3", and 4" sizes.
Is a sediment bucket included?
A -Y sediment bucket is typically an optional accessory. Add it in debris-prone locations (leaves, sand, mulch) to extend time between line cleanings.
Are bronze or nickel-bronze tops available?
Yes—use prefixes ZB (polished bronze) or ZN (polished nickel-bronze) for finished areas; base model Z is cast iron.
