Full compliance with E1 requires the drain to be part of a complete system meeting these standards, including proper sizing, sediment control, and protected outfalls to prevent flooding and ingress. - Clause G13 Foul water: Performance G13.3.1, G13.3.1(a), G13.3.1(b), G13.3.1(c), G13.3.1(d), G13.3.2, G13.3.2(a), G13.3.2(b), G13.3.2(c), G13.3.2(d), G13.3.2(e), G13.3.2(f), G13.3.3, G13.3.4, G13.3.4(a), G13.3.4(b), G13.3.4(c), G13.3.4(d), G13.3.4(e), G13.3.4(f), G13.3.4(g), G13.3.4(h), G13.3.4(i), G13.3.4(j), G13.3.4(k)
The SPS 130S/C Vari-Level drain supports compliance with NZBC Clause G13 requirements through its design and materials. G13 mandates the safe disposal of foul water to prevent illness and loss of amenity from odour or offensive matter. The drain’s 130mm outlet and connection to 100mm pipework align with G13/AS2 acceptable solution dimensions for gravity foul water drainage.
Its cast iron body and stainless steel grate ensure durability, resistance to leakage, and structural protection from loads, addressing G13 performance needs to avoid blockages, leaks, and damage. The height-adjustable grate facilitates maintenance access to clear blockages and ventilate the drainage system per G13.3 performance requirements.
Applicable standards include AS/NZS 3500.2 for sanitary plumbing and drainage, referenced in G13 acceptable solutions. Verification methods under G13/VM4 involve demonstrating system capacity, durability, and connection to approved outfalls.
Overall, the product’s robust construction, pipe compatibility, and maintenance accessibility contribute to meeting G13's performance criteria when installed as part of a compliant plumbing system.
Notes
The SPS 130S/C Vari-Level drain, designed with a 130mm round stainless steel grate and cast-iron body, is engineered to connect with 100mm
pipework, supporting the efficient conveyance of foul and surface water in
drainage systems.
Regarding NZ Building Code (NZBC) Clause G13 Foul Water, the
drain design aligns with the performance requirement of conveying foul water
from buildings to drainage systems, minimizing blockage and leakage risk, and
allowing maintenance access, which are essential for compliance under G13.
In
relation to Clause E1 Surface Water, while the drain's grate and build support
surface water disposal, full compliance with E1’s requirements for sediment
control and protection against debris ingress depends on the drain's
integration within a compliant drainage system featuring necessary sumps and
outlets.
Therefore, the SPS 130S/C drain contributes towards meeting G13 and E1
objectives but requires appropriate system installation to fully comply with
NZBC standards.
Evidence
The product meets the requirements set out in the following documents, or relevant parts of cited standards within the documents:
The SPS 130S/C Vari-Level drain meets NZBC G13 performance requirements by serving as a reliable component in foul water drainage systems. It provides a durable and corrosion-resistant stainless-steel grate and cast-iron body that connect to 100mm pipework, enabling gravity flow conveyance of foul water while minimizing blockages and leakage.
The drain’s adjustable grate height allows effective integration with various flooring types, supporting reasonable maintenance access as required by G13 to ensure clearing blockages and ventilation to prevent foul air entry. Regarding NZBC E1, the drain satisfies part of the surface water disposal function with its grate design and robust build.
However, full E1 compliance depends on the drain’s inclusion within a comprehensive surface water system incorporating sumps, sediment traps, and proper outlet protection to prevent debris ingress and ensure sediment collection.
Thus, while the SPS 130S/C drain supports both G13 and E1 objectives structurally and functionally, full code compliance necessitates appropriate system design and certification from an Engineer or Installer confirming these standards are met
