The SPS Vari-level floor drains provide premium drainage solutions suitable for both interior and exterior environments, including commercial, industrial, and residential settings.

• These drains offer efficient drainage for both surface and foul water, ensuring watertight, durable, and maintainable systems that protect buildings and occupants from water-related risks. 
• They are designed to accommodate high water flow capacity and resist chemicals and heavy loads, making them appropriate for demanding environments.
• 200mm and 300mm square grate options possess load-bearing qualities classified as Class C according to AS3996-2006.
• Grates are available in round and square designs, featuring high-heel-friendly patterns with gaps ranging from 5mm to 5.5mm, making them suitable for pedestrian precincts.
• Hinged square grates provide for easy access for inspection and maintenance.
• Flexibility is afforded by 'O' ring seals that secure the drain to push-in connections for PVC, HDPE, and copper pipes.
• Strong and aesthetically pleasing options — The drain bodies are constructed from durable, surface-coated cast iron. The grates are made from 304 and 316 grades of stainless steel, galvanised ductile iron, bronze, linished bronze, and linished nickel bronze.

Vari-Level Design

• Featuring an integrated membrane clamp collar that can be reversed for added height, this innovative and practical design allows for adjustable heights of the grate and frame, facilitating installation and alignment with various floor levels and finishes.
• This flexibility caters to diverse floor construction requirements, enabling designers and installers to ensure optimal drainage performance from the floor.
• The design of the flange and clamp collar connection, which includes three weep hole slots, enhances the waterproofing qualities of the floor membrane system.

Typical Locations for Use

• SPS Vari-level floor drains are commonly installed in housing developments, public facilities, hotels, restaurants, schools, retail spaces, podium areas, factories, and processing plants.
• They are suitable for a variety of flooring types, including paved surfaces, cement toppings, epoxy, and tiled floors.

• The drain must be precisely matched to the projected water volume. Under-sizing can cause overflow, while oversizing leads to inefficiency.
• Installation requires specific minimum heights, e.g, 17mm–25mm, depending on the model, which may not be feasible in shallow floor constructions. A standard SPS Floor Waste Drain with a lesser height dimension may be more suitable in this situation.
• Designed for specific environments, performance may be compromised if used in unapproved contexts.
• Lack of cleaning can cause issues like odours or clogging.

Installation Requirements

• Compatible Pipework: Ensure the drain outlet size (50mm, 65mm, 80mm, 100mm) matches the connected pipework, such as PVC, HDPE, or copper pipes.
• Select a drain that is compatible with the expected environment, considering factors such as internal or external location, pedestrian and vehicle traffic, and the projected volume of water present on the floor or podium area at any given time. Other considerations include aesthetic appeal and the amount of fall, if any.
• Height Adjustment: Use the adjustable (vari-level) grate and frame assembly to set the finished surface level flush with the surrounding flooring or membrane. Observe the minimum installation height for the specific model.
• Coupling and Connection: Where required, use the appropriate coupling (e.g. E100 or E150 to connect the drain body to the drainage pipe.
• Waterproofing and Membrane Integration: For installations on membrane surfaces, ensure the drain’s membrane clamp ring is correctly integrated with the waterproofing system to prevent leaks.
• Load Rating: Select the correct grate and body combination to meet anticipated load requirements (e.g. pedestrian or vehicular traffic).
• Ensure compliance with all applicable Building and Plumbing Standards.
• Refer to product data sheet.

Maintenance & Prevention Measures

• Regular Inspection: Periodically inspect the grate and outlet for debris, blockages to maintain optimal drainage performance.
• Routine Cleaning: Establish a cleaning schedule to remove accumulated debris, especially in high-use or outdoor environments, to prevent clogging.
• Height and Position Verification: Confirm that the drain remains set at the correct height relative to the finished floor level, especially after floor resurfacing or repairs.
• Seal and Flange Inspection: Check the integrity of seals and leak-control flanges to prevent sub-surface water ingress and ensure proper drainage.
• Pipe Connection Check: Inspect connections to PVC, HDPE, or copper pipes for leaks or deterioration, and ensure couplings remain securely in place.
• Grate Security: Verify that the grate is securely fastened and undamaged to prevent unauthorised removal and maintain safety.
• Surface Water Management: Ensure the surrounding area is free from obstructions that could divert water away from the drain, reducing the risk of pooling or overflow.
• Prompt Issue Resolution: Address any signs of slow drainage or unpleasant odours immediately, as these may indicate developing blockages or plumbing issues.

SPS floor drains meet the mandatory objectives and performance criteria of NZBC Clauses G13 and E1 by providing durable, watertight, and maintainable drainage solutions that protect buildings and occupants from the risks associated with foul and surface water. SPS Drain and Cleanout Products are developed for the Plumbing and Drainage Industry and to the Australia/New Zealand Standard AS/NZ 3500.2.2. SPS floor drains are designed and manufactured to comply with the relevant requirements of the New Zealand Building Code, specifically Clauses G13 (Foul Water) and E1 (Surface Water).

NZBC Clause G13: Foul Water:

• Accessible Maintenance: SPS drains are designed for easy access, allowing for regular maintenance and cleaning, which meets the requirement for accessible, durable, and safe points within foul water drainage systems.
• Durable Materials: The use of robust cast iron bodies and 316 stainless steel or bronze grates ensures long-term durability and resistance to corrosion, as required for sanitary plumbing systems.
• Water Trap Compatibility: The drains are compatible with water traps and can be fitted with cleaning eyes, supporting the requirement to prevent foul air from entering buildings and allowing for maintenance access.
• Pipe Compatibility: SPS drains can connect to PVC, HDPE, and copper pipes, meeting NZBC requirements for approved pipe and fitting materials.
• Reliable Performance: The design supports effective foul water conveyance, minimising the risk of blockages and ensuring system reliability.

NZBC Clause E1: Surface Water:

• Efficient Surface Water Disposal: SPS vari-level drains are engineered to efficiently collect and convey surface water from floors, decks, and other surfaces to an appropriate outfall, thus protecting people and property from the adverse effects of surface water.
• Adjustable Height: The vari-level feature allows the grate assembly to be set flush with the finished surface, ensuring effective surface water capture and compliance with E1’s requirements for proper sitework and drainage.
• Blockage Prevention: The design (including grates and optional strainers) help prevent debris entry, reducing the likelihood of blockages in the drainage system as required by E1.3.3(b).
• Leakage Protection: Proper integration with waterproofing membranes and secure pipe connections helps avoid leakage and groundwater entry, aligning with E1.3.3(c).
• Watermark Certification: Many SPS drains are Watermark certified, indicating compliance with relevant standards for surface water drainage products.
