Technical Specifications, Applications, Standards and Price
The NAFFCO Test & Drain Valve is a critical component in fire sprinkler systems, designed to test system performance and safely drain water from fire protection pipelines. This valve allows system operators and inspectors to simulate sprinkler activation without triggering an actual fire event, ensuring the system is fully operational and compliant with international fire safety standards.
Manufactured by NAFFCO (National Fire Fighting Manufacturing FZCO) in the United Arab Emirates (UAE), this valve is widely used in residential, commercial, and industrial fire protection projects worldwide.
What Is a Test & Drain Valve?
A Test & Drain Valve is a control valve installed at the remote end of a sprinkler system. It serves two primary purposes:
- Testing the hydraulic performance of the sprinkler system
- Draining residual water from the pipeline during maintenance or inspections
The test orifice inside the valve is calibrated to simulate the discharge of one sprinkler head, allowing accurate testing of flow, pressure, alarms, and pump activation.
Applications of NAFFCO Test & Drain Valve
The NAFFCO Test & Drain Valve is commonly used in:
- Wet pipe sprinkler systems
- Fire protection risers
- High-rise residential buildings
- Commercial complexes and shopping malls
- Industrial plants and warehouses
- Hospitals, data centers, and sensitive facilities
Its precise performance makes it essential for periodic fire system inspections.

Main Components of NAFFCO Test & Drain Valve
Valve Body
Manufactured from high-quality ductile iron or bronze, ensuring high pressure tolerance and long service life.
Test Orifice
A precisely sized opening that simulates the discharge of a standard sprinkler head.
Shut-Off Valve
Allows controlled opening and closing during testing and draining operations.
Drain Outlet
Safely directs discharged water away from the system to prevent damage or flooding.
Difference Between Test & Drain Valve and Drain Valve
Many projects mistakenly use standard drain valves instead of test & drain valves. The difference is critical:
| Feature | Test & Drain Valve | Drain Valve |
|---|---|---|
| Simulates sprinkler flow | ✅ Yes | ❌ No |
| System performance testing | ✅ Yes | ❌ No |
| Water drainage | ✅ Yes | ✅ Yes |
| NFPA compliance | ✅ Required | ❌ Not sufficient |
For NFPA-compliant systems, a NAFFCO Test & Drain Valve is strongly recommended.
Installation Location in Fire Sprinkler Systems
According to NFPA standards, the Test & Drain Valve should be installed:
- At the hydraulically most remote point of the system
- At the end of the riser or branch line
- In an accessible location for inspection and maintenance
Correct installation ensures accurate testing results and system approval.
Role of Test & Drain Valve in Fire Pump Testing
During testing, opening the NAFFCO Test & Drain Valve creates a pressure drop in the system.
- Proper pump operation
- Correct pressure switch settings
- Functional alarm systems
Importance for Fire Safety Approval
Fire authorities and third-party inspectors require proper testing of sprinkler systems. A missing or non-functional test & drain valve can result in:
- Failure to obtain fire safety approval
- Delays in project handover
- Increased safety risks
Using certified NAFFCO valves helps ensure smooth approval processes.
Available Sizes of NAFFCO Test & Drain Valve
NAFFCO Test & Drain Valves are commonly available in:
- 1 inch
- 1½ inch
- 2 inch
The correct size should be selected based on system design calculations.
Standards and Certifications
NAFFCO Test & Drain Valves are designed in compliance with:
- NFPA 13 – Installation of Sprinkler Systems
- NFPA 25 – Inspection, Testing and Maintenance
- UL / FM approvals (available for selected models)
These certifications make the valve suitable for international projects.
Price of NAFFCO Test & Drain Valve
The price depends on several factors:
- Valve size
- Body material
- Certifications (UL / FM)
- Project quantity and delivery location
For accurate pricing and technical consultation, it is recommended to contact authorized suppliers such as Tetis Sazeh, a specialized provider of NAFFCO firefighting equipment.
Maintenance and Inspection Guidelines
To ensure long-term reliability:
- Perform periodic testing
- Check for leaks or corrosion
- Keep the drain outlet clear
- Verify alarm and pump activation during tests
Regular maintenance extends the valve’s lifespan and ensures system readiness.
