ERA PP Acoustic Drainage System

Compliant with EN1451-1 | Enjoy Quiet Living

Product Introduction

ERA PP Acoustic Drainage System is a high-performance gravity soil & waste drainage solution engineered for modern buildings. Built with innovative three-layer composite PP structure and fully certified to EN1451-1 European standard, it physically suppresses drainage-generated noise, delivers outstanding heat resistance and mechanical strength. The complete pipe-and-fitting portfolio with push-fit connections simplifies site installation, creating a peaceful indoor environment for residential, commercial and public-building projects.

Core Technology: Three-Layer Composite Noise-Reduction Structure

Layer-by-layer noise reduction achieves physical sound elimination without additional wrapping materials.

Inner Layer — Eco-Friendly PP

Smooth inner bore mitigates water impact and friction, cutting down water-collision noise inside the pipeline.

Middle Layer — Polymer Sound-Absorbing Layer

Embedded high-density sound-absorbing polymer material effectively blocks sound wave transmission and dampens vibration.

Outer Layer — Impact-Resistant PP Reinforced Layer

Robust anti-impact & anti-vibration outer shell safeguards pipeline integrity, ensuring stable long-term operation even in complex installation conditions.

Key Features & Advantages

Superior Acoustic Performance

Multi-layer damping construction absorbs both airborne and structure-borne noise from wastewater flow. No extra acoustic lagging required, greatly enhancing indoor comfort

Reliable High-Temperature Resistance
Premium heat-resistant PP raw material supports ≈70°

Continuous operating temperature, and withstands short-term hot-water discharge up to ≈90°

Fully adapted for waste water from showers, washing machines and dishwashers.

Flexible Quick-Insert Installation

One-step push-fit socket connection with integrated EPDM sealing ring.
Greatly shortens construction cycles and reduces labour costs.

Flexible joints absorb water-flow vibration to avoid noise transfer across building structures, while providing reliable leak-proof performance. Full range of pipes, bends, branches, inspection ports and reducers available in DN50-DN160.

Excellent Mechanical & Chemical Performance

Mineral-reinforced PP material delivers high impact resistance,anti-crack performance on-site. Resists most domestic wastewater chemical corrosion,with a 50-year design service life. Halogen-free and fully recyclable for sustainable building projects.

EN1451-1 Standard Compliance

Conforms to European standard EN1451-1 for building soil & waste plastic piping systems, suitable for Application Area B / BD: indoor gravity drainage and in-structure buried installation.

Wide Application Scenarios

ERA PP Acoustic Drainage System fits diverse building projects where low-noise drainage is essential：

Residential buildings & luxury apartments
Hotels
Hospitals & healthcare facilities
Schools
Office buildings
Indoor gravity soil-waste drainage, ventilation and rainwater discharge systems.
