In-House Quality Assurance Laboratory Testing Protocols

Real testing benchmarks performed on every batch. We subject water housings, fittings, and filter elements to extreme hydraulic pressure and cycle fatigue to eliminate field failure risks.

EXTREME STRESS TEST Protocol Ref: CWS-LAB-HYD-500

500 PSI Hydrostatic Burst Pressure Test Bench

Computerized hydraulic pressure bench ramps complete RO manifolds and 10" filter housing bowls to 500 PSI (3.45 MPa) with continuous hold for 15 minutes. While residential line pressure is typically 40โ€“80 PSI, our 500 PSI benchmark guarantees a 3.5x safety margin against sudden municipal water hammer spikes.

Test Pressure:
500 PSI (3.45 MPa)
Hold Duration:
15 Minutes Continuous
Failure Criterion:
Zero Deformation / Leak

100,000 Cycle Water Hammer Impulse Fatigue Bench

Servo-controlled high-speed impulse valves subject water filter housings and POM quick fittings to 100,000 continuous cycles of 0 to 150 PSI (0 to 1.0 MPa) pulsation at 30 cycles per minute. This simulates over 10 years of harsh residential water hammer without thread fatigue or fitting separation.
