Compliance Statement
Scope of Use
SPS Basket Traps are primarily designed for commercial and industrial settings such as commercial kitchens, food processing plants, bars, and refuse areas where capturing solid waste like food debris is vital before wastewater enters the drainage system.
They serve as an essential first stage in trade waste pre-treatment, helping to meet discharge standards. Basket Traps should only be used indoors. These products are not suitable for stormwater applications. They must be installed on floors with cement screed, vinyl, tiles, or resin finishes.
Constructed from durable materials such as stainless steel, bronze, and cast iron, the traps feature removable and fixed strainers, as well as a range of grate designs (round, square, hinged, bayonet) to match different flooring and access requirements.
Correct sizing, installation, and maintenance are crucial for compliance with NZBC E1, G13, and relevant standards.
New Zealand Building Code (NZBC)
The product will, if employed in accordance with the supplier's installation and maintenance requirements, assist with meeting the following provisions of the building code:
- Clause E1 Surface water: Performance E1.3.1, E1.3.2, E1.3.3, E1.3.3(a), E1.3.3(b), E1.3.3(c), E1.3.3(d), E1.3.3(e), E1.3.3(f)
SPS Basket Trap Drains help meet all E1 Surface Water code requirements by efficiently collecting and conveying surface water to suitable outfalls, using gravity flow where possible (E1.3.3a). Their removable baskets prevent blockages (E1.3.3b), and their robust, watertight design prevents leakage and root ingress (E1.3.3c).
Proper installation ensures surface water does not enter buildings during heavy rainfall (E1.3.2) and prevents damage or nuisance to neighbouring properties (E1.3.1). By adhering to Acceptable Solutions such as E1/AS1 and industry standards, they help protect people, property, and drainage system outfalls from the adverse effects of surface water, as required under all E1 performance clauses. - 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)
SPS Basket Trap Drains satisfy all G13 Foul Water clauses by capturing solids, preventing blockages (G13.3.1, G13.3.2b), and safely conveying wastewater to appropriate outfalls (G13.3.1a, G13.3.2a). Their robust, watertight construction and correct installation avoid leaks and root entry (G13.3.1b, G13.3.2c), while basket access enables maintenance and cleaning (G13.3.1d, G13.3.2d).
Designed for durability, they resist damage from loads or ground movement (G13.3.2f) and can integrate with venting systems to avoid foul air in buildings (G13.3.1c, G13.3.2e).
Notes
SPS Basket Traps are designed to comply with the NZBC requirements Clauses E1 Surface Water and G13 Foul Water.G13 SPS Basket Trap Floor Wastes comply with G13/AS1, which is the Acceptable Solution for Clause G13. SPS drains are designed to safely trap solid waste and food debris, ensure watertightness, and allow access for cleaning. Their compliance is recognised for settings such as kitchens, food processing, and similar environments. Importantly, they meet both the NZBC and the relevant standard AS/NZS 3500.2.2.
E1–SPS drains are designed to meet Clause E1 by providing drainage solutions that protect buildings from surface water risks. This includes resilience against surface water ingress, which is vital for E1 compliance. These drains will help prevent surface water from entering foul water systems and causing flooding or nuisance, aligning with the Code’s intent.
SPS Basket Traps have secondary relevance to B1-Structure and B2-Durability regarding robustness.
Evidence
The product meets the requirements set out in the following documents, or relevant parts of cited standards within the documents:
SPS Basket Trap Drains are designed to meet NZBC E1 (Surface Water) standards by effectively collecting and guiding surface water from floor areas into the drainage system, reducing the risk of flooding, water ingress, or nuisance on site. Their design includes removable baskets to intercept debris and prevent blockages, facilitating easy maintenance and ensuring optimal water flow.
For G13 (Foul Water), SPS Basket Traps comply with G13/AS1 and AS/NZS 3500.2 standards by providing watertightness, preventing foul air leaks, and maintaining hygiene through debris isolation and accessible cleaning.
Constructed from stainless steel, bronze, or cast iron, they meet B2 (Durability) requirements for a long service life. Certified load ratings for certain models (e.g., Class C) conform to B1 (Structure), allow them to withstand commercial floor loads without failure.
Correct product selection, installation according to manufacturer instructions, and regular maintenance are essential to consistently meet these standards, ensuring reliable and compliant performance in demanding environments.
Design requirements
The SPS Basket Trap range is designed for cement toppings and vinyl flooring surfaces in commercial kitchens, food processing plants, bars, and similar areas where capturing solid debris before wastewater enters the plumbing is crucial.
Restrictions include exclusive use in commercial or industrial settings and installation according to the specified outlet size, number, and floor type. SPS Basket Traps with O-rings fit into 100mm and 150mm PVC or HDPE pipes.
Appearance options include round or square 304 or 316 stainless steel grates, with polished or satin finishes. The bodies are made from stainless steel or cast iron.
Features include easy-access bayonet or hinged grates, removable baskets, a fixed strainer, Load Class C ratings, and height-adjustable grates. Alternative grates and fixings are available to meet site-specific requirements.
Installation involves placing the trap below the floor in riser pipes; for vinyl floors, a clamping ring is used.
Installation requirements
SPS Basket Traps need a stable, level surface such as concrete, screed, or sheet vinyl, free of debris and prepared for secure fitting and fixture stability.
Installation should take place in ambient temperatures suitable for handling piping and drain materials, avoiding extreme weather that could affect sealing and jointing.
Installers must comply with NZBC and NZS standards. Preparatory work includes verifying pipe alignments and ensuring pipe ends are clean; floor surfaces should be prepared for waterproofing if needed.
Fixing entails securely installing the trap into the pipe or leak control flange with proper sealing to ensure watertight joints by NZBC solutions G13/AS1 and E1/AS1.
For vinyl floors, a clamping ring is used to secure the flooring to the grate. Grates are fixed with screws or bayonet fittings.
Ensure the floor is flush to prevent trip hazards and to enable proper drainage. Installation guides are available in datasheets and the SPS catalogue.
Maintenance requirements
With regular maintenance, SPS Basket Traps will meet NZBC B2 standards to ensure durability. Maintenance includes cleaning debris from the removable basket when needed or at the end of a shift, and conducting regular checks for blockages, damage, or water ponding.
Neglecting maintenance can cause system blockages and reduce durability, which may void warranties. During construction, contractors must prevent exposure to corrosive substances or mechanical damage. Businesses should stick to cleaning schedules and quickly resolve blockages to avoid early deterioration.
Use non-corrosive chemicals for cleaning. Do not use a wire brush on the grate, as it will damage the surface. Flushing with hot water occasionally helps remove buildup and prevents organic matter growth.
At the end of its life, SPS products made from stainless steel, bronze, or cast iron are recyclable, supporting environmentally responsible recycling and disposal.
