Water Purifier Filter Housing Bursting and Flooding the Floor? NL-FBH-6 Filter Bottle & Housing Pressure and Leak Test Bench Runs Six Stations (pump test bench)

A water purifier filter housing bursting and flooding the floor is one of the costliest complaints a maker can face: the cause is usually insufficient pressure margin in the bottle or a poor thread / O-ring seal on the housing, so a working-pressure surge in service turns into a leak or a crack. Incoming inspection normally stops at appearance and flow-through, which reveals neither the pressure margin nor a micro-leak; the deviation only surfaces after the unit is plumbed in, at significant rework and warranty cost.

What the NL-FBH-6 filter bottle and housing pressure and leak bench measures

• Six stations in parallel, with automatic pressure ramp and hold on a constant-pressure water circuit while leakage and pressure decay are logged (sharing the water-supply and metering module of our pump test bench systems)
• Hold-pressure and burst-pressure measurement, giving the true pressure margin of every unit, with automatic stop and protection on failure
• Water-hammer pulse cycling to reproduce fatigue from rapid valve opening and closing
• Micro-leak localisation on threads, O-rings and bonded joints, quantifying leaks that bubble testing cannot see
• Temperature cycling to reproduce pressure-margin decay under hot-water conditions
• Barcode and batch binding, with raw data exported per unit for batch comparison

Applicable standards

GB/T 30307 (household and similar drinking water treatment units), GB 4706.1 (household appliances – general safety), GB 34914 (water efficiency of water purifiers) and the customer's standard; hold and pulse criteria are set as multiples of the unit's working pressure.

Stations and throughput

Six stations running 24/7 bring a single hold-and-burst measurement down from tens of minutes of manual pressure testing to about ten minutes, while pulse fatigue is completed within weeks — so incoming lots can be sampled batch by batch.
