Zurn Z556 – 8" Adjustable Heavy-Duty Drain

An 8" diameter, heavy-duty area drain with Dura-Coated cast-iron body, bottom outlet, seepage pan, and a combination membrane flashing clamp & frame for adjustable extension—topped by a heavy-duty slotted cast-iron grate for long service in exposed environments.

The Zurn Z556 is built for point drainage where durability and service access matter. In technical terms, it’s an 8" top, Dura-Coated cast-iron drain with a bottom outlet, seepage pan, and an adjustable clamp/frame assembly furnished with a heavy-duty slotted grate. In everyday language: it ties neatly into waterproofing, handles traffic loads, and lets you dial in finish elevation during install.

Installation Highlights

1) Set & Anchor

Position the body at rough elevation; anchor per detail; verify positive slope to the drain across the slab or paver bed.

2) Tie-In Membrane

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

3) Adjust & Commission

Fine-tune the frame to finished grade; install/secure the grate; schedule periodic clean-outs (and bucket service if specified).

Case Study: Deck Overlay Retrofit

A municipal garage planned a polymer overlay over an uneven slab. The team selected Zurn Z556 for its adjustable clamp/frame, which let installers dial in grate elevation after waterproofing and overlay. Outfitted with 3" No-Hub outlets and -TS secured tops, the drains eliminated ponding at low points and simplified seasonal clean-outs with optional -Y buckets.

Frequently Asked Questions

What does “adjustable” mean on Z556?
The frame and clamping assembly allow small height adjustments at finish, so you can match the grate to pavers, overlays, or slope corrections without re-setting the entire body.
Which outlet connection should I choose?
Match to your piping: No-Hub (NH) for cast-iron systems, Threaded (IP) for steel, or Inside Caulk (IC) / Inside Gasket (IG) / Neo-Loc (NL) based on detailing—commonly in 2", 3", or 4" sizes.
Is a sediment bucket included?
The -Y sediment bucket is an optional accessory for debris capture. Add it where grit or leaves are common to extend time between downstream cleanings.
