Zurn Z1731 – Floor Drain (Medium Depth), 9" Diameter

A 9" (229 mm) medium-depth, heavy-duty stainless steel floor drain with an integral anchor flange and loose-set plain grate—engineered for corrosion resistance and reliable intake in commercial and industrial environments.

In technical terms, the Zurn Z1731 is an all Type 304 (CF8) cast stainless body with a non-tilt, loose-set grate and anchoring flange; it’s available with multiple outlet types and sizes. In plain English: it’s a tough, stainless drain that ties securely into your slab and keeps water moving—ideal for process areas, loading corridors, wash bays, and decks.

Key Features

  • 9" diameter top with heavy-duty loose-set plain grate for dependable surface capture.
  • Cast stainless steel body (Type 304 standard) with integral anchor flange for secure slab embedment.
  • Corrosion-resistant construction for food & beverage, healthcare, and washdown applications.
  • Outlet families: NH No-Hub, IC Inside Caulk, IP Threaded, and BW Butt-Weld (specify pipe schedule for BW).
  • Typical pipe sizes: 2", 3", 4" (by outlet type).
  • Material prefix option: ZM (Type 316) for elevated chloride/chemical exposure.

Where Z1731 Excels

Specify Z1731 for service corridors, processing rooms, wash bays, and parking/deck retrofits where stainless construction, secure anchoring, and medium-depth capacity are needed. The loose-set grate speeds maintenance, while stainless components stand up to caustic cleaners and brine.

Popular Options & Accessories

  • -K seepage holes only; -KC clamp collar with seepage holes for membrane tie-in.
  • -TS top secured; -VP vandal-proof hardware; -SF satin finish top.
  • -Y sediment bucket; -YM fabricated mesh bucket for finer debris.

Installation Highlights

1) Set & Reinforce

Place the body to rough elevation; fasten via the integral anchor flange to rebar/chairs for stability during the pour.

2) Select the Outlet

Match your piping: NH/IC/IP as required, or BW and specify pipe schedule (10/40/80) for welded stainless systems.

3) Waterproofing & Protect

Use -KC where membranes are present; protect grate and collar during finishing to preserve alignment and sealing.

Case Study: Washdown Corridor Retrofit

A food-processing corridor experienced corrosion on painted drains and slow draw-down after frequent sanitation. Replacing them with Zurn Z1731 (Type 316 bodies for brine exposure, 3" NH outlets, -KC clamp collars) eliminated rust staining and improved seal reliability. Maintenance reported faster cleanup cycles and fewer downstream clogs where -Y buckets were installed at grit-prone locations.

Frequently Asked Questions

When should I upgrade to Type 316 stainless (ZM)?
Choose ZM in higher-chloride or aggressive chemical environments—coastal sites, salt tracking, or caustic washdowns—thanks to improved pitting resistance vs. Type 304.
Which outlet connection is right?
NH for no-hub cast-iron systems, IC for inside-caulk, IP for threaded steel, and BW for fully welded stainless (specify pipe schedule 10/40/80).
Do I need a sediment bucket?
Use -Y where grit, sand, or food solids are present—or -YM for finer capture. It simplifies clean-outs and protects downstream piping.
