Effortless Testing Process

1. Seal off the drain to be tested with the 6" Steel Drain Test Plugs, ensuring the pipe surface is clean and smooth.
2. Replace the Blanking Cap on one plug with the Nipple Cap.
3. Divide the Air Test Tubing into three lengths.
4. Fill the ‘U’ Air Gauge with water and level it at at zero.
5. Connect the Air Test Tubing to the Hand Bellows, Drain Test Plugs, and ‘U’ Air Gauge using the ‘Y’ Piece.
6. Pump the Hand Bellows until a pressure of 100mm (4") of water is shown on the gauge. Allow 5 minutes for air temperature to stabilise and adjust back to 100mm.
7. The water level should not drop by more than 25mm over a 5-minute period, without additional pumping.
