It’s a high-efficiency system that uses negative pressure to rapidly drain rainwater from large roof areas using fewer and smaller pipes.
Unlike gravity systems, siphonic drainage doesn’t require sloped pipes or multiple downpipes. This allows for more design flexibility, cleaner aesthetics, and reduced installation costs.
Yes, Akasison is ideal for high-rise applications and eliminates the need for vertical stacks.
Yes, with proper design adjustments, Akasison can be integrated into existing structures.
The system uses durable HDPE pipes with electrofusion joints, ensuring leakproof and long-lasting performance.
No, the high-velocity flow keeps the pipes clean, reducing the need for frequent maintenance.
Installation should be done by trained professionals. Ashirvad provides technical support and training to ensure proper setup.
Ensure the hydraulic design is done by certified professionals. Use only Ashirvad-approved outlets and fittings. Follow the installation guidelines for electrofusion joints. Conduct regular inspections after installation. Train your installation team with support from Ashirvad’s technical experts.
Do not mix siphonic and gravity systems in the same pipeline. Do not alter the pipe layout without consulting the design team. Do not use incompatible materials or adhesives. Do not ignore air-blocking requirements at outlets. Do not install the system without proper fastening and support.
