At Future Drainage and Groundworks, trading as Blocked Drains Harrogate, we understand the importance of ensuring that your drainage system is functioning properly. One effective way to verify the integrity of your drainage system is through air testing. In this article, we will provide a step-by-step guide on how to air test drainage in North Yorkshire.

Air testing is a non-destructive method used to verify the integrity of a drainage system. It involves introducing compressed air into the system and measuring the pressure loss over a set period. This test can help identify any leaks or defects in the system, ensuring that your drainage system is safe and functional.

Before conducting an air test, it's essential to ensure that the drainage system is prepared correctly. This includes:

• Ensuring all drains and vents are sealed
• Disconnecting any water supply lines
• Filling the system with water to a depth of at least 1 meter
• Installing a test plug or cap to seal the system

To conduct an air test, follow these steps:

1. Connect a compressor to the test plug or cap, and introduce compressed air into the system.
2. Monitor the pressure gauge and record the initial pressure reading.
3. Allow the system to stabilize for 5 minutes.
4. Record the pressure reading after 5 minutes.
5. Calculate the pressure loss over the 5-minute period.

The results of the air test are measured in mm of water column loss per minute. The acceptable loss rate varies depending on the pipe diameter and pipeline length. As a general rule, a loss rate of:

• 0-10 mm/min is considered acceptable for pipes up to 100mm in diameter
• 0-5 mm/min is considered acceptable for pipes between 100-200mm in diameter
• 0-2 mm/min is considered acceptable for pipes over 200mm in diameter

When conducting an air test, it's essential to take necessary safety precautions to avoid injury or damage to the system. These include:

• Ensuring the system is properly sealed to prevent air leaks
• Using a compressor with a pressure gauge to monitor the pressure
• Wearing protective gear, such as safety glasses and gloves
• Ensuring the area is clear of any obstacles or hazards

Air testing is a reliable method for verifying the integrity of a drainage system. By following the steps outlined in this guide, you can ensure that your drainage system is functioning properly and safely.
