Zurn Z315 – Finish-Floor Drain

The Z315 is a robust finish-floor drain assembly featuring a Dura-Coated cast-iron body, adjustable nickel bronze strainer, and anchoring/clamping features that speed installation and deliver a clean, flush finish in tile, terrazzo, or resinous floors.

In technical terms, Z315 combines a cast-iron body with anchor flange, weep/relief openings for waterproofing, and an adjustable top with a secured strainer. In plain English: it’s a workhorse floor drain that sets flush, manages seepage at the membrane plane, and keeps maintenance straightforward.

Key Features

  • Adjustable finish-floor top — dials in a flush, trip-free set at punch-list time.
  • Nickel bronze strainer — durable, corrosion-resistant, and architecturally clean.
  • Cast-iron body with anchor flange — locks into slab and resists construction abuse.
  • Weep/relief path — helps drain moisture from above the membrane to protect finishes.
  • Multiple outlet options — common sizes and outlet types to match branch piping (verify on submittal).

Where Z315 Excels

Ideal for restrooms, locker rooms, back-of-house corridors, lobbies, and amenity areas. The adjustable top achieves a tight, clean perimeter; the body’s anchoring and seepage control support long-term floor performance.

Benefits (Plain English)

  • Cleaner installs — top adjustability makes final elevation easy across varied tile thicknesses.
  • Protected finishes — weep path relieves moisture at the waterproofing layer.
  • Predictable upkeep — secured strainer simplifies routine cleaning and prevents lost parts.
