How to Conduct a Fire Hydrant Pressure Test in Singapore: Step by Step

Fire protection is not a choice, especially in a densely populated and urban country like Singapore. A fire hydrant is the most vital component of every building's fire protection system. Adequate testing ensures hydrants function at optimum capacity when it is most desperately required. In this guidebook, we will take you through conducting a fire hydrant pressure test in Singapore step by step, as per local codes and standards.

What is the Fire Hydrant Pressure Test?

Fire hydrant pressure test in Singapore is a procedure that advises whether a hydrant is being supplied with the right water pressure and flow rate to facilitate firefighting activities. The test determines the residual and static pressure, and the flow capacity of the hydrant.

In Singapore, they also need to meet the SCDF criteria, which include testing the fire hydrants routinely that are installed in commercial, industrial, and residential buildings. 

Why Is It Important in Singapore?

Conducting a fire hydrant pressure test in Singapore is not only a great safety measure—it's the law. Failure to do so might result in fines, insurance issues, or worse in the case of a real emergency. The Singapore cityscape of skyscrapers makes perfect execution of water systems more important than ever.

Step-by-Step Guide on How to Conduct a Fire Hydrant Pressure Test in Singapore

Step 1: Pre-Test Preparation

Before performing any test, inform respective parties like building management, other tenants in the area, and SCDF if required. Check:

• Check maintenance record of the hydrant

• Check for visible external damage or leakage

• Check the hydrant is still accessible and not obstructed

Also, collect the necessary tools:

• Flow test gauge

• Pitot tube

• Pressure gauge

• Wrenches and valve keys

• Personal Protective Equipment (PPE)

Step 2: Isolate and Inspect the Hydrant

Close isolating valves close to the hydrant if needed and perform quick visual inspection of the hydrant. These are:

• Checking outlet caps

• Valve stems

• Nozzle threads

• For rust or corrosion signs

Physical inspection is to be performed before performing a fire hydrant pressure test in Singapore because it can identify potential mechanical defects in advance.

Step 3: Mount Pressure and Flow Measuring Equipment

Mount the pressure gauge on the outlet nozzle and the flow gauge or pitot tube on the outlet for the water to be discharged. Secure mounting of all equipment in order to avoid leaks and dubious results.

Do not forget to use a calibrated set of equipment, especially in Singapore where precision is more important for regulatory requirements.

Step 4: Record Static Pressure

Slowly turn on the hydrant to pressure up the system and take a reading of the static pressure—the system pressure without any water flowing. Make a note of this reading before opening the discharge nozzle.

This reading provides a starting reading for the pressure potential of the water supply before flow begins.

Step 5: Open the Discharge Nozzle and Measure Residual Pressure

Now open the discharge nozzle to allow water flow. With water flowing, measure the residual pressure—the system pressure with water flowing.

Note the reading of the flow rate using the pitot gauge or flow test gauge at this stage. These readings will indicate whether the hydrant is performing according to the SCDF's performance standards.

Step 6: Shut Down and Restore the System

When taking readings

• Slowly shut hydrant valve

• Remove gauges and equipment

• Drain off excess water to prevent freezing or rusting

• Replace all caps and tighten all sections

When tested, ensure the hydrant returns to service condition and document all readings in the maintenance record.

Common Challenges & Best Practices

1. Unstable Pressure Readings

Water pressure in Singapore varies according to the location of the building and the time of day. Test at steady low-usage periods whenever feasible.

2. Weather Conditions

Although Singapore enjoys a tropical climate, too much rain and flooding can hinder smooth discharge. Test under favorable weather conditions.

3. Documentation

Keep detailed records for all fire hydrant pressure test in Singapore. This allows for future audits, inspections, and planning for maintenance.

Regulatory Compliance in Singapore

The SCDF Fire Code and SS 575:2012 specs determine the hydrant's technical specifications and how often it is supposed to be tested. Annual testing conducted by a competent fire safety contractor is usually the standard.

Failure to comply with such codes will see one incurring a fine, and the worst, liability under the law should the hydrant cause failure during a response operation during emergencies.

Conclusion: Prioritize Safety with Proper Testing

A good Fire hydrant pressure test in singapore is not a checklist—it's ensuring that every person in the building is safe. In a country like Singapore with high urban population density and strict fire codes, regular testing is inevitable.

For building owners and building managers who need reassurance, professional service is highly recommended. Drakofire is one such company widely recognized for its accurate testing and compliance with standard, offering efficient and effective service across Singapore. From periodic inspection to thorough pressure analysis, Drakofire can ensure your fire hydrant system is always prepared for any event.
