GET YOUR FREE QUOTE NOWWhat Is Hydrostatic Testing?
When it comes to fire protection systems, few tests are as critical—or as often overlooked—as the hydrostatic test. Apex Pumps provides AS1851-compliant hydrostatic testing for fire pumps, hydrant systems, booster assemblies, PRVs, and fire pipework.
Hydrostatic testing applies controlled water pressure to fire protection equipment to verify structural integrity, pressure capacity, and system reliability under fire conditions.
Hydrostatic testing is required every five years under AS1851 to ensure your system can withstand real-world emergency pressures. If your system has not been hydrostatically tested within the required interval, both compliance and insurance coverage may be at risk.
Hydrostatic testing reveals issues that cannot be detected through visual checks or routine annual maintenance.
| Typical Components Tested | Why It's Critical |
|---|---|
| Fire pump casings | Detects leaks, cracks, corrosion, and structural fatigue |
| Hydrant pipework and valves | Ensures the system can withstand brigade-assisted pressures |
| Booster assemblies | Validates AS1851 compliance |
| Pressure relief and reduction valves | Prevents system failure during fire events |
| Isolation and control valves | Provides verifiable evidence for insurance and certifiers |
| Fire service pipework | Reveals issues not detected through visual checks |
| Sprinkler system components | Ensures reliability under real-world fire conditions |
| Flexible couplings and fittings | Maintains system integrity and operational safety |
AS1851 & AS2941 Hydrostatic Testing Requirements
Apex Pumps performs all hydrostatic tests in accordance with:
- AS1851:2012 — Routine Service of Fire Protection Systems
- AS2941 — Fixed Fire Protection Installations — Pumpsets
- NSW Annual Fire Safety Statement (AFSS) requirements
| Fire System Asset | Hydrostatic Test Frequency | Relevant Standard |
|---|---|---|
| Fire Pump Casings | Every 5 years | AS1851 / AS2941 |
| Hydrant System Valves & Components | Every 5 years | AS1851 |
| Booster Assemblies | 5-year integrity test | AS1851 |
| PRVs & Control Valves | 5-year overhaul & pressure test | AS1851 |
| Fire Pipework Under Pressure | Required testing | AS1851 |
Missing a hydrostatic test is one of the most common causes of AFSS non-compliance in NSW.
Our Hydrostatic Testing Process
1 Pre-Test Assessment
+We begin with:
- System isolation checks
- Visual inspection of pipework
- Valve condition checks
- Verification of test points
- Safety risk assessment
- Confirmation of appropriate AS1851 pressures
This ensures safe, accurate testing.
2 Controlled Pressurisation
+Using calibrated test equipment, we elevate pressure to AS1851/AS2941 levels:
- Fire Pumps: Typically 1.5 × duty pressure
- Hydrant Systems: Pressure per AS1851 table
- Booster Assemblies: Fire brigade operating pressure
- Valves & PRVs: Manufacturer-defined test ranges
We hold pressure and monitor:
- Pressure loss
- Structural deformation
- Leakage points
- Gasket and flange integrity
- Valve performance
- Pump controller response
3 Integrity Verification
+During and after the test, we document:
- Leaks or cracks
- Weak pipe sections
- PRV or valve malfunction
- Pump casing failure
- Fitting or flange fatigue
- Incorrect installation issues
If defects are found, isolation and urgent rectification may be required.
4 Compliance Reporting & Certification
+Every hydrostatic test includes:
- AS1851 hydrostatic test certificate
- Pressure logs and duration records
- Photos of all test points
- Defect reports with severity rankings
- Recommended rectification steps
- AFSS-ready documentation
Our reports meet fire certifier and insurer requirements.

Why Hydrostatic Testing Matters
Hydrostatic testing exposes hidden failures that annual servicing cannot detect.
Common failures we uncover:
- Corroded pipework inside risers and shafts
- Cracked hydrant valves under load
- Weak booster pipe sections
- PRVs leaking under emergency pressure
- Pump casing fatigue
- Loose or incorrectly installed fittings
- Gaskets that pass annual tests but fail under real fire conditions
The consequences of skipping hydrostatic testing:
- AFSS rejection
- Delayed occupancy certificates
- Insurance claim denial
- Severe legal liability in fire events
- Total system failure during fire brigade boost operations

Frequently Asked Questions
How often is hydrostatic testing required under AS1851?
+Hydrostatic testing is required every 5 years for fire pumps, hydrant valves, booster assemblies, PRVs, and other key system components as specified in AS1851.
What happens if we skip the five-year hydrostatic test?
+You risk:
- AFSS non-compliance
- Insurance claim denial
- Hidden system weaknesses
- Total system failure under fire brigade pressure
Skipping hydrostatic testing exposes the building owner and strata committee to significant legal liability.
Can hydrostatic testing damage the system?
+When performed incorrectly — yes.
When performed by trained AS1851 technicians — no.
Our controlled pressurisation prevents overloading while ensuring valid structural verification.
How long does the test take?
+Most hydrostatic tests are completed within 2–4 hours, depending on building access and complexity.
Do I need to notify occupants or fire brigade?
+Some buildings require notification depending on isolation requirements. We advise and assist with all necessary pre-test procedures.
Can Apex Pumps provide rectification if the system fails the test?
+Yes. We repair fire pumps, hydrant valves, PRVs, booster assemblies, fittings, flanges, controllers, and pipework defects.
