In a high-rise, every flush above you is a sound problem. Silent drainage pipes solve it at the source.
In a premium high-rise, residents below shouldn't hear a flush from above. Standard PVC SWR stacks transmit flow noise through walls and slabs — Kwiet silent drainage pipes solve that with a three-layer polypropylene wall engineered specifically for acoustic damping.
Three-Layer Construction
Outer layer — impact-resistant skin.
Middle mineral-loaded layer — dense acoustic damping core.
Inner smooth layer — high-flow, anti-deposit bore.
Acoustic Performance
Independent testing shows installed noise levels under 17 dB(A) at typical flow rates — well below the 30 dB(A) limit used in premium European hospitality specifications.
Where to Specify Kwiet
Premium residential high-rises and villas.
Five-star hotels and luxury serviced apartments.
Hospitals and quiet healthcare zones.
Studio buildings and acoustic-sensitive spaces.
Installation
Kwiet pipes use rubber-ring socket joints with standard SWR/DWV brackets at extended spacing. No special tools required.
Frequently Asked Questions
What is a silent drainage pipe?
A silent (or low-noise) drainage pipe uses a mineral-loaded multi-layer wall to damp flow and impact noise — typically achieving installed sound levels under 17 dB(A).
Where are Kwiet pipes used?
Premium high-rises, five-star hotels, hospitals and any space where waste-stack noise transfer is unacceptable.
Can Kwiet pipes replace standard SWR?
Yes. Kwiet pipes use standard SWR sizes and brackets and can replace conventional PVC SWR stacks one-for-one.
