Zurn commercial toilets (Z5675 floor-mount, Z5615 wall-mount, Z5685 sensor-ready, Z5560 light-commercial) integrate primarily with Zurn flushometer valves — not the residential Korky/Fluidmaster aftermarket ecosystem. Most "Zurn parts" service involves the flushometer valve (Z6000 series) rather than the bowl itself, since the bowl is tankless on commercial models.
For facility maintenance teams, the Zurn commercial parts ecosystem is centered on three components: flushometer valve rebuild kits, flushometer valve replacement, and bowl-bowl mounting hardware. For the Z5560 light-commercial gravity-tank toilet, residential parts apply (Korky 2032BP flapper, Fluidmaster 400A fill valve).
Zurn parts compatibility by model
| Zurn model | Parts ecosystem | Most-replaced components |
|---|---|---|
| Z5675 (floor-mount flushometer) | Zurn Z6000 flushometer + commercial seat | Z6000 rebuild kit, diaphragm assembly, mounting bolts |
| Z5615 (wall-mount flushometer) | Z6000 flushometer + commercial seat + Z1203/Z1204 wall carrier | Z6000 rebuild, wall carrier service, mounting hardware |
| Z5685 (sensor-ready) | Z6000-WS sensor flushometer + commercial seat | Sensor battery, sensor module, Z6000-WS rebuild |
| Z5560 (light-commercial gravity) | Residential aftermarket (Korky/Fluidmaster) + commercial seat | Korky 2032BP flapper, Fluidmaster 400A fill valve, tank-bowl gasket |
Zurn Z6000 flushometer rebuild service
The Z6000 (and Z6000-WS sensor variant) are the dominant components in Zurn commercial toilet service. Typical service intervals:
- Diaphragm replacement: every 5-7 years in 200+ daily flush use ($25-$40 rebuild kit)
- Full Z6000 replacement: every 12-18 years ($160-$240)
- Sensor module (Z6000-WS): every 5-8 years ($120-$180 module + battery)
- Battery (Z6000-WS1): every 2-3 years (4 AA batteries, $4-$6)
Commercial-specific seat replacement
Zurn commercial bowls use heavier-duty seats than residential. Recommended:
- Bemis 7300 Commercial ($28-$45) — open-front, heavy-duty plastic, commercial spec
- Olsonite 95 Commercial ($35-$55) — heavier-duty, ADA-compliant, commercial school/healthcare
- Bemis Heavy Duty Commercial ($45-$75) — premium grade for high-traffic restrooms
Standard residential SoftClose seats (Bemis 1500EC) do NOT meet commercial spec — they wear within 6-12 months in high-traffic use. Always use commercial-grade seats on Zurn bowls.
