1. Check the water supply: Ensure that the water supply to the cold-water system is turned on and functioning properly.
2. Inspect the pipes: Check for any visible signs of damage or leaks in the pipes that may affect the performance of the cold-water system.
3. Test the water pressure: Use a pressure gauge to measure the water pressure in the system. The pressure should be within the recommended range for the specific system.
4. Check the temperature: Use a thermometer to measure the temperature of the cold water coming out of the taps. The temperature should be within the recommended range for cold water.
5. Test the flow rate: Turn on the taps and measure the flow rate of the cold water. The flow rate should be consistent and adequate for the needs of the system.
6. Check for air in the system: Bleed any air out of the system by opening the taps and allowing the water to flow until all air is removed.
7. Inspect the fixtures: Check the faucets, showerheads, and other fixtures connected to the cold-water system for any leaks or malfunctions.
8. Test the water quality: Use a water testing kit to check the quality of the cold water, including pH levels, hardness, and any contaminants.
9. Record the results: Keep detailed records of all tests and measurements taken during the testing process for future reference.
10. Make any necessary repairs or adjustments: If any issues are identified during testing, make the necessary repairs or adjustments to ensure the cold-water system is functioning properly.

Standard Procedures for Testing a Cold-Water System
1. Preparation
- Obtain necessary equipment (pressure gauge, flowmeter, sanitizer, test kit, etc.)
- Ensure the system is clean and free of debris
- Isolate the system from other water sources
2. Pressure Test
- Close all fixtures and faucets
- Connect the pressure gauge to a test point
- Slowly open the main isolation valve
- Monitor pressure readings and ensure they meet specifications (typically between 40-80 psi)
- If pressure is below specifications, investigate leaks or other issues
3. Flow Rate Test
- Open the fixtures and faucets to maximum flow
- Connect the flowmeter to a test point
- Measure the flow rate in gallons per minute (GPM)
- Compare the measured flow rate to the design specifications
- If flow rate is below specifications, check for clogs, restrictions, or inadequate pipe sizing
4. Disinfection
- Drain the system and allow to air dry
- Follow manufacturer's instructions to prepare a chlorine or other sanitizing solution
- Recirculate the sanitizing solution through the system for the required contact time
- Drain the system and flush with clean water to remove the disinfectant
5. Water Quality Test
- Collect water samples at designated test points
- Test water samples for parameters such as pH, chlorine residual, total coliforms, and other potential contaminants
- Compare results to EPA or local water quality standards
6. Operational Check
- Open all fixtures and faucets to ensure proper operation
- Check for leaks, water hammer, or other operational issues
- Adjust flow rates or make repairs as necessary
7. Documentation
- Record all test results, observations, and actions taken
- Maintain a log or report for future reference
- Provide documentation to relevant authorities or stakeholders as required
Additional Considerations
- Use certified equipment and follow manufacturer's instructions
- Observe safety precautions and wear appropriate personal protective equipment
- Consult with a licensed plumber or water quality professional if any issues or concerns arise
